+Date: May 2008

+Description:
+ The Trusted Computing Group(TCG) runtime Integrity
+ Measurement Architecture(IMA) maintains a list of hash
+ values of executables and other sensitive system files
+ loaded into the run-time of this system. At runtime,
+ the policy can be constrained based on LSM specific data.
+ Policies are loaded into the securityfs file ima/policy
+ by opening the file, writing the rules one at a time and
+ then closing the file. The new policy takes effect after
+ the file ima/policy is closed.
+
+ rule format: action [condition ...]
+
+ action: measure | dont_measure
+ condition:= base | lsm
+ base: [[func=] [mask=] [fsmagic=] [uid=]]
+ lsm: [[subj_user=] [subj_role=] [subj_type=]
+ [obj_user=] [obj_role=] [obj_type=]]
+
+ base: func:= [BPRM_CHECK][FILE_MMAP][INODE_PERMISSION]
+ mask:= [MAY_READ] [MAY_WRITE] [MAY_APPEND] [MAY_EXEC]
+ fsmagic:= hex value
+ uid:= decimal value
+ lsm: are LSM specific
+
+ default policy:
+ # PROC_SUPER_MAGIC
+ dont_measure fsmagic=0x9fa0
+ # SYSFS_MAGIC
+ dont_measure fsmagic=0x62656572
+ # DEBUGFS_MAGIC
+ dont_measure fsmagic=0x64626720
+ # TMPFS_MAGIC
+ dont_measure fsmagic=0x01021994
+ # SECURITYFS_MAGIC
+ dont_measure fsmagic=0x73636673
+
+ measure func=BPRM_CHECK
+ measure func=FILE_MMAP mask=MAY_EXEC
+ measure func=INODE_PERM mask=MAY_READ uid=0
+
+ The default policy measures all executables in bprm_check,
+ all files mmapped executable in file_mmap, and all files
+ open for read by root in inode_permission.
+
+ Examples of LSM specific definitions:
+
+ SELinux:
+ # SELINUX_MAGIC
+ dont_measure fsmagic=0xF97CFF8C
+
+ dont_measure obj_type=var_log_t
+ dont_measure obj_type=auditd_log_t
+ measure subj_user=system_u func=INODE_PERM mask=MAY_READ
+ measure subj_role=system_r func=INODE_PERM mask=MAY_READ
+
+ Smack:
+ measure subj_user=_ func=INODE_PERM mask=MAY_READ

+ This document describes how to write an

+ ALSA (Advanced Linux Sound Architecture)</citetitle></ulink>
+ driver. The document focuses mainly on PCI soundcards.
+ In the case of other device types, the API might

+ consistent, and therefore it would be still a bit help for
+ writing them.
+ </para>
+
+ <para>
+ This document targets people who already have enough
+ C language skills and have basic linux kernel programming
+ knowledge. This document doesn't explain the general
+ topic of linux kernel coding and doesn't cover low-level
+ driver implementation details. It only describes
+ the standard way to write a PCI sound driver on ALSA.
+ </para>
+
+ <para>
+ If you are already familiar with the older ALSA ver.0.5.x API, you
+ can check the drivers such as <filename>sound/pci/es1938.c</filename> or
+ <filename>sound/pci/maestro3.c</filename> which have also almost the same
+ code-base in the ALSA 0.5.x tree, so you can compare the differences.

+ <para>
+ The ALSA drivers are provided in two ways.
+ </para>
+
+ <para>
+ One is the trees provided as a tarball or via cvs from the
+ ALSA's ftp site, and another is the 2.6 (or later) Linux kernel
+ tree. To synchronize both, the ALSA driver tree is split into
+ two different trees: alsa-kernel and alsa-driver. The former
+ contains purely the source code for the Linux 2.6 (or later)
+ tree. This tree is designed only for compilation on 2.6 or
+ later environment. The latter, alsa-driver, contains many subtle
+ files for compiling ALSA drivers outside of the Linux kernel tree,
+ wrapper functions for older 2.2 and 2.4 kernels, to adapt the latest kernel API,
+ and additional drivers which are still in development or in
+ tests. The drivers in alsa-driver tree will be moved to
+ alsa-kernel (and eventually to the 2.6 kernel tree) when they are
+ finished and confirmed to work fine.
+ </para>
+
+ <para>
+ The file tree structure of ALSA driver is depicted below. Both
+ alsa-kernel and alsa-driver have almost the same file
+ structure, except for <quote>core</quote> directory. It's
+ named as <quote>acore</quote> in alsa-driver tree.

+ interrupt handler looks usually like the following:
+
+ <informalexample>
+ <programlisting>
+<![CDATA[
+ static irqreturn_t snd_mychip_interrupt(int irq, void *dev_id)
+ {
+ struct mychip *chip = dev_id;
+ ....
+ return IRQ_HANDLED;
+ }
+]]>
+ </programlisting>
+ </informalexample>
+ </para>
+
+ <para>
+ Now let's write the corresponding destructor for the resources
+ above. The role of destructor is simple: disable the hardware
+ (if already activated) and release the resources. So far, we
+ have no hardware part, so the disabling code is not written here.
+ </para>
+
+ <para>
+ To release the resources, the <quote>check-and-release</quote>
+ method is a safer way. For the interrupt, do like this:
+
+ <informalexample>
+ <programlisting>
+<![CDATA[
+ if (chip->irq >= 0)
+ free_irq(chip->irq, chip);
+]]>
+ </programlisting>
+ </informalexample>
+
+ Since the irq number can start from 0, you should initialize
+ chip->irq with a negative value (e.g. -1), so that you can
+ check the validity of the irq number as above.
+ </para>
+
+ <para>
+ When you requested I/O ports or memory regions via
+ <function>pci_request_region()</function> or
+ <function>pci_request_regions()</function> like in this example,
+ release the resource(s) using the corresponding function,
+ <function>pci_release_region()</function> or
+ <function>pci_release_regions()</function>.
+
+ <informalexample>
+ <programlisting>
+<![CDATA[
+ pci_release_regions(chip->pci);
+]]>
+ </programlisting>
+ </informalexample>
+ </para>
+
+ <para>
+ When you requested manually via <function>request_region()</function>
+ or <function>request_mem_region</function>, you can release it via
+ <function>release_resource()</function>. Suppose that you keep
+ the resource pointer returned from <function>request_region()</function>
+ in chip->res_port, the release procedure looks like:
+
+ <informalexample>
+ <programlisting>
+<![CDATA[
+ release_and_free_resource(chip->res_port);
+]]>
+ </programlisting>
+ </informalexample>
+ </para>
+
+ <para>
+ Don't forget to call <function>pci_disable_device()</function>
+ before the end.
+ </para>
+
+ <para>
+ And finally, release the chip-specific record.
+
+ <informalexample>
+ <programlisting>
+<![CDATA[
+ kfree(chip);
+]]>
+ </programlisting>
+ </informalexample>
+ </para>
+
+ <para>
+ Again, remember that you cannot
+ use the <parameter>__devexit</parameter> prefix for this destructor.
+ </para>
+
+ <para>
+ We didn't implement the hardware disabling part in the above.
+ If you need to do this, please note that the destructor may be
+ called even before the initialization of the chip is completed.
+ It would be better to have a flag to skip hardware disabling
+ if the hardware was not initialized yet.
+ </para>
+
+ <para>
+ When the chip-data is assigned to the card using
+ <function>snd_device_new()</function> with
+ <constant>SNDRV_DEV_LOWLELVEL</constant> , its destructor is
+ called at the last. That is, it is assured that all other
+ components like PCMs and controls have already been released.
+ You don't have to stop PCMs, etc. explicitly, but just
+ call low-level hardware stopping.
+ </para>
+
+ <para>
+ The management of a memory-mapped region is almost as same as
+ the management of an I/O port. You'll need three fields like
+ the following:
+
+ <informalexample>
+ <programlisting>
+<![CDATA[
+ struct mychip {
+ ....
+ unsigned long iobase_phys;
+ void __iomem *iobase_virt;
+ };
+]]>
+ </programlisting>
+ </informalexample>
+
+ and the allocation would be like below:
+
+ <informalexample>
+ <programlisting>
+<![CDATA[
+ if ((err = pci_request_regions(pci, "My Chip")) < 0) {
+ kfree(chip);
+ return err;

+ chip->iobase_virt = ioremap_nocache(chip->iobase_phys,
+ pci_resource_len(pci, 0));
+]]>
+ </programlisting>
+ </informalexample>
+
+ and the corresponding destructor would be:
+
+ <informalexample>
+ <programlisting>

+ <title>Registration of Device Struct</title>
+ <para>
+ At some point, typically after calling <function>snd_device_new()</function>,
+ you need to register the struct <structname>device</structname> of the chip

+ so that it stores the PCI's device pointer to the card. This will be
+ referred by ALSA core functions later when the devices are registered.
+ </para>

+ So far, so good. Let's finish the missing PCI

+
+ <para>
+ The first and second fields of

+ The PCM middle layer of ALSA is quite powerful and it is only
+ necessary for each driver to implement the low-level functions
+ to access its hardware.
+ </para>
+
+ <para>
+ For accessing to the PCM layer, you need to include
+ <filename><sound/pcm.h></filename> first. In addition,
+ <filename><sound/pcm_params.h></filename> might be needed
+ if you access to some functions related with hw_param.

+
+ <para>
+ Each card device can have up to four pcm instances. A pcm
+ instance corresponds to a pcm device file. The limitation of
+ number of instances comes only from the available bit size of
+ the Linux's device numbers. Once when 64bit device number is
+ used, we'll have more pcm instances available.
+ </para>
+
+ <para>
+ A pcm instance consists of pcm playback and capture streams,
+ and each pcm stream consists of one or more pcm substreams. Some
+ soundcards support multiple playback functions. For example,
+ emu10k1 has a PCM playback of 32 stereo substreams. In this case, at
+ each open, a free substream is (usually) automatically chosen
+ and opened. Meanwhile, when only one substream exists and it was
+ already opened, the successful open will either block
+ or error with <constant>EAGAIN</constant> according to the
+ file open mode. But you don't have to care about such details in your
+ driver. The PCM middle layer will take care of such work.

+ The PCM configurations are stored in the runtime instance
+ after the application sends <type>hw_params</type> data via

+ sw_params structs. For example,
+ <structfield>format</structfield> holds the format type

+ <constant>SNDRV_PCM_FORMAT_XXX</constant>.
+ </para>
+
+ <para>
+ One thing to be noted is that the configured buffer and period
+ sizes are stored in <quote>frames</quote> in the runtime.
+ In the ALSA world, 1 frame = channels * samples-size.
+ For conversion between frames and bytes, you can use the
+ <function>frames_to_bytes()</function> and

+ The <structfield>dma_area</structfield> holds the buffer

+ <function>memcpy</function> from/to
+ this pointer. Meanwhile, <structfield>dma_addr</structfield>
+ holds the physical address of the buffer. This field is
+ specified only when the buffer is a linear buffer.
+ <structfield>dma_bytes</structfield> holds the size of buffer
+ in bytes. <structfield>dma_private</structfield> is used for

+ <section id="buffer-and-memory-external-hardware">
+ <title>External Hardware Buffers</title>
+ <para>
+ Some chips have their own hardware buffers and the DMA
+ transfer from the host memory is not available. In such a case,
+ you need to either 1) copy/set the audio data directly to the
+ external hardware buffer, or 2) make an intermediate buffer and
+ copy/set the data from it to the external hardware buffer in
+ interrupts (or in tasklets, preferably).
+ </para>
+
+ <para>
+ The first case works fine if the external hardware buffer is large
+ enough. This method doesn't need any extra buffers and thus is
+ more effective. You need to define the
+ <structfield>copy</structfield> and
+ <structfield>silence</structfield> callbacks for
+ the data transfer. However, there is a drawback: it cannot
+ be mmapped. The examples are GUS's GF1 PCM or emu8000's
+ wavetable PCM.
+ </para>
+
+ <para>
+ The second case allows for mmap on the buffer, although you have
+ to handle an interrupt or a tasklet to transfer the data
+ from the intermediate buffer to the hardware buffer. You can find an
+ example in the vxpocket driver.
+ </para>
+
+ <para>
+ Another case is when the chip uses a PCI memory-map
+ region for the buffer instead of the host memory. In this case,
+ mmap is available only on certain architectures like the Intel one.
+ In non-mmap mode, the data cannot be transferred as in the normal
+ way. Thus you need to define the <structfield>copy</structfield> and
+ <structfield>silence</structfield> callbacks as well,
+ as in the cases above. The examples are found in
+ <filename>rme32.c</filename> and <filename>rme96.c</filename>.
+ </para>
+
+ <para>
+ The implementation of the <structfield>copy</structfield> and
+ <structfield>silence</structfield> callbacks depends upon
+ whether the hardware supports interleaved or non-interleaved
+ samples. The <structfield>copy</structfield> callback is
+ defined like below, a bit
+ differently depending whether the direction is playback or
+ capture:
+
+ <informalexample>
+ <programlisting>
+<![CDATA[
+ static int playback_copy(struct snd_pcm_substream *substream, int channel,
+ snd_pcm_uframes_t pos, void *src, snd_pcm_uframes_t count);
+ static int capture_copy(struct snd_pcm_substream *substream, int channel,
+ snd_pcm_uframes_t pos, void *dst, snd_pcm_uframes_t count);
+]]>
+ </programlisting>
+ </informalexample>
+ </para>
+
+ <para>
+ In the case of interleaved samples, the second argument
+ (<parameter>channel</parameter>) is not used. The third argument
+ (<parameter>pos</parameter>) points the
+ current position offset in frames.
+ </para>
+
+ <para>
+ The meaning of the fourth argument is different between
+ playback and capture. For playback, it holds the source data
+ pointer, and for capture, it's the destination data pointer.
+ </para>
+
+ <para>
+ The last argument is the number of frames to be copied.
+ </para>
+
+ <para>
+ What you have to do in this callback is again different
+ between playback and capture directions. In the
+ playback case, you copy the given amount of data
+ (<parameter>count</parameter>) at the specified pointer
+ (<parameter>src</parameter>) to the specified offset
+ (<parameter>pos</parameter>) on the hardware buffer. When
+ coded like memcpy-like way, the copy would be like:
+
+ <informalexample>
+ <programlisting>
+<![CDATA[
+ my_memcpy(my_buffer + frames_to_bytes(runtime, pos), src,
+ frames_to_bytes(runtime, count));
+]]>
+ </programlisting>
+ </informalexample>
+ </para>
+
+ <para>
+ For the capture direction, you copy the given amount of
+ data (<parameter>count</parameter>) at the specified offset
+ (<parameter>pos</parameter>) on the hardware buffer to the
+ specified pointer (<parameter>dst</parameter>).
+
+ <informalexample>
+ <programlisting>
+<![CDATA[
+ my_memcpy(dst, my_buffer + frames_to_bytes(runtime, pos),
+ frames_to_bytes(runtime, count));
+]]>
+ </programlisting>
+ </informalexample>
+
+ Note that both the position and the amount of data are given
+ in frames.
+ </para>
+
+ <para>
+ In the case of non-interleaved samples, the implementation
+ will be a bit more complicated.
+ </para>
+
+ <para>
+ You need to check the channel argument, and if it's -1, copy
+ the whole channels. Otherwise, you have to copy only the
+ specified channel. Please check
+ <filename>isa/gus/gus_pcm.c</filename> as an example.
+ </para>
+
+ <para>
+ The <structfield>silence</structfield> callback is also
+ implemented in a similar way.
+
+ <informalexample>
+ <programlisting>
+<![CDATA[

+ </para>
+
+ <para>
+ The meanings of arguments are the same as in the

+ callback, although there is no <parameter>src/dst</parameter>
+ argument. In the case of interleaved samples, the channel
+ argument has no meaning, as well as on
+ <structfield>copy</structfield> callback.
+ </para>
+
+ <para>
+ The role of <structfield>silence</structfield> callback is to

+ (<parameter>count</parameter>) of silence data at the

+ ALSA provides an easy interface for procfs. The proc files are

+ To create a proc file, call

+ struct snd_info_entry *entry;
+ int err = snd_card_proc_new(card, "my-file", &entry);
+]]>
+ </programlisting>
+ </informalexample>
+
+ where the second argument specifies the name of the proc file to be

+ <filename>my-file</filename> under the card directory,
+ e.g. <filename>/proc/asound/card0/my-file</filename>.
+ </para>

+ Like other components, the proc entry created via

+ </para>
+
+ <para>
+ When the creation is successful, the function stores a new

+ ALSA provides a verbose version of the
+ <function>printk()</function> function. If a kernel config
+ <constant>CONFIG_SND_VERBOSE_PRINTK</constant> is set, this
+ function prints the given message together with the file name
+ and the line of the caller. The <constant>KERN_XXX</constant>
+ prefix is processed as
+ well as the original <function>printk()</function> does, so it's
+ recommended to add this prefix, e.g.
+
+ <informalexample>
+ <programlisting>
+<![CDATA[
+ snd_printk(KERN_ERR "Oh my, sorry, it's extremely bad!\n");
+]]>
+ </programlisting>
+ </informalexample>
+ </para>
+
+ <para>
+ There are also <function>printk()</function>'s for
+ debugging. <function>snd_printd()</function> can be used for
+ general debugging purposes. If
+ <constant>CONFIG_SND_DEBUG</constant> is set, this function is
+ compiled, and works just like
+ <function>snd_printk()</function>. If the ALSA is compiled
+ without the debugging flag, it's ignored.
+ </para>
+
+ <para>
+ <function>snd_printdd()</function> is compiled in only when

+15. The whole point of call_rcu(), synchronize_rcu(), and friends
+ is to wait until all pre-existing readers have finished before
+ carrying out some otherwise-destructive operation. It is
+ therefore critically important to -first- remove any path
+ that readers can follow that could be affected by the
+ destructive operation, and -only- -then- invoke call_rcu(),
+ synchronize_rcu(), or friends.
+
+ Because these primitives only wait for pre-existing readers,

sampling_rate: measured in uS (10^-6 seconds), this is how often you
want the kernel to look at the CPU usage and to make decisions on
what to do about the frequency. Typically this is set to values of
-around '10000' or more.

+around '10000' or more. It's default value is (cmp. with users-guide.txt):
+transition_latency * 1000
+The lowest value you can set is:
+transition_latency * 100 or it may get restricted to a value where it
+makes not sense for the kernel anymore to poll that often which depends
+on your HZ config variable (HZ=1000: max=20000us, HZ=250: max=5000).
+Be aware that transition latency is in ns and sampling_rate is in us, so you
+get the same sysfs value by default.
+Sampling rate should always get adjusted considering the transition latency
+To set the sampling rate 750 times as high as the transition latency
+in the bash (as said, 1000 is default), do:
+echo `$(($(cat cpuinfo_transition_latency) * 750 / 1000)) \
+ >ondemand/sampling_rate
+
+show_sampling_rate_(min|max): THIS INTERFACE IS DEPRECATED, DON'T USE IT.
+You can use wider ranges now and the general
+cpuinfo_transition_latency variable (cmp. with user-guide.txt) can be
+used to obtain exactly the same info:
+show_sampling_rate_min = transtition_latency * 500 / 1000
+show_sampling_rate_max = transtition_latency * 500000 / 1000
+(divided by 1000 is to illustrate that sampling rate is in us and
+transition latency is exported ns).

+Introduction
+============
+
+This document describes how to use the dynamic debug (ddebug) feature.
+
+Dynamic debug is designed to allow you to dynamically enable/disable kernel
+code to obtain additional kernel information. Currently, if
+CONFIG_DYNAMIC_DEBUG is set, then all pr_debug()/dev_debug() calls can be
+dynamically enabled per-callsite.
+
+Dynamic debug has even more useful features:
+
+ * Simple query language allows turning on and off debugging statements by
+ matching any combination of:
+
+ - source filename
+ - function name
+ - line number (including ranges of line numbers)
+ - module name
+ - format string
+
+ * Provides a debugfs control file: <debugfs>/dynamic_debug/control which can be
+ read to display the complete list of known debug statements, to help guide you
+
+Controlling dynamic debug Behaviour
+===============================
+
+The behaviour of pr_debug()/dev_debug()s are controlled via writing to a
+control file in the 'debugfs' filesystem. Thus, you must first mount the debugfs
+filesystem, in order to make use of this feature. Subsequently, we refer to the
+control file as: <debugfs>/dynamic_debug/control. For example, if you want to
+enable printing from source file 'svcsock.c', line 1603 you simply do:
+
+nullarbor:~ # echo 'file svcsock.c line 1603 +p' >
+ <debugfs>/dynamic_debug/control
+
+If you make a mistake with the syntax, the write will fail thus:
+
+nullarbor:~ # echo 'file svcsock.c wtf 1 +p' >
+ <debugfs>/dynamic_debug/control
+-bash: echo: write error: Invalid argument
+
+Viewing Dynamic Debug Behaviour
+===========================
+
+You can view the currently configured behaviour of all the debug statements
+via:
+
+nullarbor:~ # cat <debugfs>/dynamic_debug/control
+# filename:lineno [module]function flags format
+/usr/src/packages/BUILD/sgi-enhancednfs-1.4/default/net/sunrpc/svc_rdma.c:323 [svcxprt_rdma]svc_rdma_cleanup - "SVCRDMA Module Removed, deregister RPC RDMA transport\012"
+/usr/src/packages/BUILD/sgi-enhancednfs-1.4/default/net/sunrpc/svc_rdma.c:341 [svcxprt_rdma]svc_rdma_init - "\011max_inline : %d\012"
+/usr/src/packages/BUILD/sgi-enhancednfs-1.4/default/net/sunrpc/svc_rdma.c:340 [svcxprt_rdma]svc_rdma_init - "\011sq_depth : %d\012"
+/usr/src/packages/BUILD/sgi-enhancednfs-1.4/default/net/sunrpc/svc_rdma.c:338 [svcxprt_rdma]svc_rdma_init - "\011max_requests : %d\012"
+...
+
+
+You can also apply standard Unix text manipulation filters to this
+data, e.g.
+
+nullarbor:~ # grep -i rdma <debugfs>/dynamic_debug/control | wc -l
+62
+
+nullarbor:~ # grep -i tcp <debugfs>/dynamic_debug/control | wc -l
+42
+
+Note in particular that the third column shows the enabled behaviour
+flags for each debug statement callsite (see below for definitions of the
+flags). The default value, no extra behaviour enabled, is "-". So
+you can view all the debug statement callsites with any non-default flags:
+
+nullarbor:~ # awk '$3 != "-"' <debugfs>/dynamic_debug/control
+# filename:lineno [module]function flags format
+/usr/src/packages/BUILD/sgi-enhancednfs-1.4/default/net/sunrpc/svcsock.c:1603 [sunrpc]svc_send p "svc_process: st_sendto returned %d\012"
+
+
+Command Language Reference
+==========================
+
+At the lexical level, a command comprises a sequence of words separated
+by whitespace characters. Note that newlines are treated as word
+separators and do *not* end a command or allow multiple commands to
+be done together. So these are all equivalent:
+
+nullarbor:~ # echo -c 'file svcsock.c line 1603 +p' >
+ <debugfs>/dynamic_debug/control
+nullarbor:~ # echo -c ' file svcsock.c line 1603 +p ' >
+ <debugfs>/dynamic_debug/control
+nullarbor:~ # echo -c 'file svcsock.c\nline 1603 +p' >
+ <debugfs>/dynamic_debug/control
+nullarbor:~ # echo -n 'file svcsock.c line 1603 +p' >
+ <debugfs>/dynamic_debug/control
+
+Commands are bounded by a write() system call. If you want to do
+multiple commands you need to do a separate "echo" for each, like:
+
+nullarbor:~ # echo 'file svcsock.c line 1603 +p' > /proc/dprintk ;\
+> echo 'file svcsock.c line 1563 +p' > /proc/dprintk
+
+or even like:
+
+nullarbor:~ # (
+> echo 'file svcsock.c line 1603 +p' ;\
+> echo 'file svcsock.c line 1563 +p' ;\
+> ) > /proc/dprintk
+
+At the syntactical level, a command comprises a sequence of match
+specifications, followed by a flags change specification.
+
+command ::= match-spec* flags-spec
+
+The match-spec's are used to choose a subset of the known dprintk()
+callsites to which to apply the flags-spec. Think of them as a query
+with implicit ANDs between each pair. Note that an empty list of
+match-specs is possible, but is not very useful because it will not
+match any debug statement callsites.
+
+A match specification comprises a keyword, which controls the attribute
+of the callsite to be compared, and a value to compare against. Possible
+keywords are:
+
+match-spec ::= 'func' string |
+ 'file' string |
+ 'module' string |
+ 'format' string |
+ 'line' line-range
+
+line-range ::= lineno |
+ '-'lineno |
+ lineno'-' |
+ lineno'-'lineno
+// Note: line-range cannot contain space, e.g.
+// "1-30" is valid range but "1 - 30" is not.
+
+lineno ::= unsigned-int
+
+The meanings of each keyword are:
+
+func
+ The given string is compared against the function name
+ of each callsite. Example:
+
+ func svc_tcp_accept
+
+file
+ The given string is compared against either the full
+ pathname or the basename of the source file of each
+ callsite. Examples:
+
+ file svcsock.c
+ file /usr/src/packages/BUILD/sgi-enhancednfs-1.4/default/net/sunrpc/svcsock.c
+
+module
+ The given string is compared against the module name
+ of each callsite. The module name is the string as
+ seen in "lsmod", i.e. without the directory or the .ko
+ suffix and with '-' changed to '_'. Examples:
+
+ module sunrpc
+ module nfsd
+
+format
+ The given string is searched for in the dynamic debug format
+ string. Note that the string does not need to match the
+ entire format, only some part. Whitespace and other
+ special characters can be escaped using C octal character
+ escape \ooo notation, e.g. the space character is \040.
+ Alternatively, the string can be enclosed in double quote
+ characters (") or single quote characters (').
+ Examples:
+
+ format svcrdma: // many of the NFS/RDMA server dprintks
+ format readahead // some dprintks in the readahead cache
+ format nfsd:\040SETATTR // one way to match a format with whitespace
+ format "nfsd: SETATTR" // a neater way to match a format with whitespace
+ format 'nfsd: SETATTR' // yet another way to match a format with whitespace
+
+line
+ The given line number or range of line numbers is compared
+ against the line number of each dprintk() callsite. A single
+ line number matches the callsite line number exactly. A
+ range of line numbers matches any callsite between the first
+ and last line number inclusive. An empty first number means
+ the first line in the file, an empty line number means the
+ last number in the file. Examples:
+
+ line 1603 // exactly line 1603
+ line 1600-1605 // the six lines from line 1600 to line 1605
+ line -1605 // the 1605 lines from line 1 to line 1605
+ line 1600- // all lines from line 1600 to the end of the file
+
+The flags specification comprises a change operation followed
+by one or more flag characters. The change operation is one
+of the characters:
+
+-
+ remove the given flags
+
++
+ add the given flags
+
+=
+ set the flags to the given flags
+
+The flags are:
+
+p
+ Causes a printk() message to be emitted to dmesg
+
+Note the regexp ^[-+=][scp]+$ matches a flags specification.
+Note also that there is no convenient syntax to remove all
+the flags at once, you need to use "-psc".
+
+Examples
+========
+
+// enable the message at line 1603 of file svcsock.c
+nullarbor:~ # echo -n 'file svcsock.c line 1603 +p' >
+ <debugfs>/dynamic_debug/control
+
+// enable all the messages in file svcsock.c
+nullarbor:~ # echo -n 'file svcsock.c +p' >
+ <debugfs>/dynamic_debug/control
+
+// enable all the messages in the NFS server module
+nullarbor:~ # echo -n 'module nfsd +p' >
+ <debugfs>/dynamic_debug/control
+
+// enable all 12 messages in the function svc_process()
+nullarbor:~ # echo -n 'func svc_process +p' >
+ <debugfs>/dynamic_debug/control
+
+// disable all 12 messages in the function svc_process()
+nullarbor:~ # echo -n 'func svc_process -p' >
+ <debugfs>/dynamic_debug/control
+
+// enable messages for NFS calls READ, READLINK, READDIR and READDIR+.
+nullarbor:~ # echo -n 'format "nfsd: READ" +p' >
+ <debugfs>/dynamic_debug/control
Secmark, it is time to deprecate the older mechanism and start the
process of removing the old code.

- <para>
- This document describes how to write an
- <ulink url="http://www.alsa-project.org/"><citetitle>
- ALSA (Advanced Linux Sound Architecture)</citetitle></ulink>
- driver. The document focuses mainly on PCI soundcards.
- In the case of other device types, the API might
- be different, too. However, at least the ALSA kernel API is
- consistent, and therefore it would be still a bit help for
- writing them.
- </para>
-
- <para>
- This document targets people who already have enough
- C language skills and have basic linux kernel programming
- knowledge. This document doesn't explain the general
- topic of linux kernel coding and doesn't cover low-level
- driver implementation details. It only describes
- the standard way to write a PCI sound driver on ALSA.
- </para>
-
- <para>
- If you are already familiar with the older ALSA ver.0.5.x API, you
- can check the drivers such as <filename>sound/pci/es1938.c</filename> or
- <filename>sound/pci/maestro3.c</filename> which have also almost the same
- code-base in the ALSA 0.5.x tree, so you can compare the differences.

- <section id="file-tree-general">
- <title>General</title>
- <para>
- The ALSA drivers are provided in two ways.
- </para>
-
- <para>
- One is the trees provided as a tarball or via cvs from the
- ALSA's ftp site, and another is the 2.6 (or later) Linux kernel
- tree. To synchronize both, the ALSA driver tree is split into
- two different trees: alsa-kernel and alsa-driver. The former
- contains purely the source code for the Linux 2.6 (or later)
- tree. This tree is designed only for compilation on 2.6 or
- later environment. The latter, alsa-driver, contains many subtle
- files for compiling ALSA drivers outside of the Linux kernel tree,
- wrapper functions for older 2.2 and 2.4 kernels, to adapt the latest kernel API,
- and additional drivers which are still in development or in
- tests. The drivers in alsa-driver tree will be moved to
- alsa-kernel (and eventually to the 2.6 kernel tree) when they are
- finished and confirmed to work fine.
- </para>
-
- <para>
- The file tree structure of ALSA driver is depicted below. Both
- alsa-kernel and alsa-driver have almost the same file
- structure, except for <quote>core</quote> directory. It's
- named as <quote>acore</quote> in alsa-driver tree.

- This directory contains code shared among different drivers
- on different architectures. They are hence supposed not to be

- <title>Card Instance</title>
- <para>
- For each soundcard, a <quote>card</quote> record must be allocated.
- </para>
-
- <para>
- A card record is the headquarters of the soundcard. It manages
- the whole list of devices (components) on the soundcard, such as
- PCM, mixers, MIDI, synthesizer, and so on. Also, the card
- record holds the ID and the name strings of the card, manages
- the root of proc files, and controls the power-management states
- and hotplug disconnections. The component list on the card
- record is used to manage the correct release of resources at
- destruction.
- </para>
-
- <para>
- As mentioned above, to create a card instance, call
- <function>snd_card_new()</function>.
-
- <informalexample>
- <programlisting>
-<![CDATA[
- struct snd_card *card;
- card = snd_card_new(index, id, module, extra_size);
-]]>
- </programlisting>
- </informalexample>
- </para>
-
- <para>
- The function takes four arguments, the card-index number, the
- id string, the module pointer (usually
- <constant>THIS_MODULE</constant>),
- and the size of extra-data space. The last argument is used to
- allocate card->private_data for the
- chip-specific data. Note that these data
- are allocated by <function>snd_card_new()</function>.
- </para>
- </section>
-
- <section id="card-management-component">
- <title>Components</title>
- <para>
- After the card is created, you can attach the components
- (devices) to the card instance. In an ALSA driver, a component is
- represented as a struct <structname>snd_device</structname> object.
- A component can be a PCM instance, a control interface, a raw
- MIDI interface, etc. Each such instance has one component
- entry.
- </para>
-
- <para>
- A component can be created via
- <function>snd_device_new()</function> function.
-
- <informalexample>
- <programlisting>
-<![CDATA[
- snd_device_new(card, SNDRV_DEV_XXX, chip, &ops);
-]]>
- </programlisting>
- </informalexample>
- </para>
-
- <para>
- This takes the card pointer, the device-level
- (<constant>SNDRV_DEV_XXX</constant>), the data pointer, and the
- callback pointers (<parameter>&ops</parameter>). The
- device-level defines the type of components and the order of
- registration and de-registration. For most components, the
- device-level is already defined. For a user-defined component,
- you can use <constant>SNDRV_DEV_LOWLEVEL</constant>.
- </para>
-
- <para>
- This function itself doesn't allocate the data space. The data
- must be allocated manually beforehand, and its pointer is passed
- as the argument. This pointer is used as the
- (<parameter>chip</parameter> identifier in the above example)
- for the instance.
- </para>
-
- <para>
- Each pre-defined ALSA component such as ac97 and pcm calls
- <function>snd_device_new()</function> inside its
- constructor. The destructor for each component is defined in the
- callback pointers. Hence, you don't need to take care of
- calling a destructor for such a component.
- </para>
-
- <para>
- If you wish to create your own component, you need to
- set the destructor function to the dev_free callback in
- the <parameter>ops</parameter>, so that it can be released
- automatically via <function>snd_card_free()</function>.
- The next example will show an implementation of chip-specific
- data.

- </para>
-
- <para>
- In the case of PCI devices, you first have to call
- the <function>pci_enable_device()</function> function before

- <title>Resource Allocation</title>
- <para>
- The allocation of I/O ports and irqs is done via standard kernel
- functions. Unlike ALSA ver.0.5.x., there are no helpers for
- that. And these resources must be released in the destructor
- function (see below). Also, on ALSA 0.9.x, you don't need to
- allocate (pseudo-)DMA for PCI like in ALSA 0.5.x.
- </para>
-
- <para>
- Now assume that the PCI device has an I/O port with 8 bytes
- and an interrupt. Then struct <structname>mychip</structname> will have the
- following fields:
-
- <informalexample>
- <programlisting>
-<![CDATA[
- struct mychip {
- struct snd_card *card;
-
- unsigned long port;
- int irq;
- };
-]]>
- </programlisting>
- </informalexample>
- </para>
-
- <para>
- For an I/O port (and also a memory region), you need to have
- the resource pointer for the standard resource management. For
- an irq, you have to keep only the irq number (integer). But you
- need to initialize this number as -1 before actual allocation,
- since irq 0 is valid. The port address and its resource pointer
- can be initialized as null by
- <function>kzalloc()</function> automatically, so you
- don't have to take care of resetting them.
- </para>
-
- <para>
- The allocation of an I/O port is done like this:
-
- <informalexample>
- <programlisting>
-<![CDATA[
- err = pci_request_regions(pci, "My Chip");
- if (err < 0) {
- kfree(chip);

- </programlisting>
- </informalexample>
- </para>
-
- <para>
- <!-- obsolete -->
- It will reserve the I/O port region of 8 bytes of the given
- PCI device. The returned value, chip->res_port, is allocated
- via <function>kmalloc()</function> by
- <function>request_region()</function>. The pointer must be
- released via <function>kfree()</function>, but there is a
- problem with this. This issue will be explained later.
- </para>
-
- <para>
- The allocation of an interrupt source is done like this:
-
- <informalexample>
- <programlisting>
-<![CDATA[
- if (request_irq(pci->irq, snd_mychip_interrupt,
- IRQF_SHARED, "My Chip", chip)) {
- printk(KERN_ERR "cannot grab irq %d\n", pci->irq);
- snd_mychip_free(chip);
- return -EBUSY;
- }
- chip->irq = pci->irq;
-]]>
- </programlisting>
- </informalexample>
-
- where <function>snd_mychip_interrupt()</function> is the
- interrupt handler defined <link
- linkend="pcm-interface-interrupt-handler"><citetitle>later</citetitle></link>.
- Note that chip->irq should be defined
- only when <function>request_irq()</function> succeeded.
- </para>
-
- <para>
- On the PCI bus, interrupts can be shared. Thus,
- <constant>IRQF_SHARED</constant> is used as the interrupt flag of
- <function>request_irq()</function>.
- </para>
-
- <para>
- The last argument of <function>request_irq()</function> is the
- data pointer passed to the interrupt handler. Usually, the
- chip-specific record is used for that, but you can use what you
- like, too.
- </para>
-
- <para>
- I won't give details about the interrupt handler at this
- point, but at least its appearance can be explained now. The
- interrupt handler looks usually like the following:
-
- <informalexample>
- <programlisting>
-<![CDATA[
- static irqreturn_t snd_mychip_interrupt(int irq, void *dev_id)
- {
- struct mychip *chip = dev_id;
- ....
- return IRQ_HANDLED;
- }
-]]>
- </programlisting>
- </informalexample>
- </para>
-
- <para>
- Now let's write the corresponding destructor for the resources
- above. The role of destructor is simple: disable the hardware
- (if already activated) and release the resources. So far, we
- have no hardware part, so the disabling code is not written here.
- </para>
-
- <para>
- To release the resources, the <quote>check-and-release</quote>
- method is a safer way. For the interrupt, do like this:
-
- <informalexample>
- <programlisting>
-<![CDATA[
- if (chip->irq >= 0)
- free_irq(chip->irq, chip);
-]]>
- </programlisting>
- </informalexample>
-
- Since the irq number can start from 0, you should initialize
- chip->irq with a negative value (e.g. -1), so that you can
- check the validity of the irq number as above.
- </para>
-
- <para>
- When you requested I/O ports or memory regions via
- <function>pci_request_region()</function> or
- <function>pci_request_regions()</function> like in this example,
- release the resource(s) using the corresponding function,
- <function>pci_release_region()</function> or
- <function>pci_release_regions()</function>.
-
- <informalexample>
- <programlisting>
-<![CDATA[
- pci_release_regions(chip->pci);
-]]>
- </programlisting>
- </informalexample>
- </para>
-
- <para>
- When you requested manually via <function>request_region()</function>
- or <function>request_mem_region</function>, you can release it via
- <function>release_resource()</function>. Suppose that you keep
- the resource pointer returned from <function>request_region()</function>
- in chip->res_port, the release procedure looks like:
-
- <informalexample>
- <programlisting>
-<![CDATA[
- release_and_free_resource(chip->res_port);
-]]>
- </programlisting>
- </informalexample>
- </para>
-
- <para>
- Don't forget to call <function>pci_disable_device()</function>
- before the end.
- </para>
-
- <para>
- And finally, release the chip-specific record.
-
- <informalexample>
- <programlisting>
-<![CDATA[
- kfree(chip);
-]]>
- </programlisting>
- </informalexample>
- </para>
-
- <para>
- Again, remember that you cannot
- use the <parameter>__devexit</parameter> prefix for this destructor.
- </para>
-
- <para>
- We didn't implement the hardware disabling part in the above.
- If you need to do this, please note that the destructor may be
- called even before the initialization of the chip is completed.
- It would be better to have a flag to skip hardware disabling
- if the hardware was not initialized yet.
- </para>
-
- <para>
- When the chip-data is assigned to the card using
- <function>snd_device_new()</function> with
- <constant>SNDRV_DEV_LOWLELVEL</constant> , its destructor is
- called at the last. That is, it is assured that all other
- components like PCMs and controls have already been released.
- You don't have to stop PCMs, etc. explicitly, but just
- call low-level hardware stopping.
- </para>
-
- <para>
- The management of a memory-mapped region is almost as same as
- the management of an I/O port. You'll need three fields like
- the following:
-
- <informalexample>
- <programlisting>
-<![CDATA[
- struct mychip {
- ....
- unsigned long iobase_phys;
- void __iomem *iobase_virt;
- };
-]]>
- </programlisting>

- and the allocation would be like below:
-

- <programlisting>
-<![CDATA[
- if ((err = pci_request_regions(pci, "My Chip")) < 0) {
- kfree(chip);
- return err;

- chip->iobase_virt = ioremap_nocache(chip->iobase_phys,
- pci_resource_len(pci, 0));
-]]>
- </programlisting>
- </informalexample>
-
- and the corresponding destructor would be:
-
- <informalexample>

-
- <section id="pci-resource-device-struct">
- <title>Registration of Device Struct</title>

- The PCM middle layer of ALSA is quite powerful and it is only
- necessary for each driver to implement the low-level functions
- to access its hardware.
- </para>
-
- <para>
- For accessing to the PCM layer, you need to include
- <filename><sound/pcm.h></filename> first. In addition,
- <filename><sound/pcm_params.h></filename> might be needed
- if you access to some functions related with hw_param.
- </para>
-
- <para>
- Each card device can have up to four pcm instances. A pcm
- instance corresponds to a pcm device file. The limitation of
- number of instances comes only from the available bit size of
- the Linux's device numbers. Once when 64bit device number is
- used, we'll have more pcm instances available.
- </para>
-
- <para>
- A pcm instance consists of pcm playback and capture streams,
- and each pcm stream consists of one or more pcm substreams. Some
- soundcards support multiple playback functions. For example,
- emu10k1 has a PCM playback of 32 stereo substreams. In this case, at
- each open, a free substream is (usually) automatically chosen
- and opened. Meanwhile, when only one substream exists and it was
- already opened, the successful open will either block
- or error with <constant>EAGAIN</constant> according to the
- file open mode. But you don't have to care about such details in your
- driver. The PCM middle layer will take care of such work.

- Ok, let's go back again to the PCM runtime records.
- The most frequently referred records in the runtime instance are
- the PCM configurations.
- The PCM configurations are stored in the runtime instance
- after the application sends <type>hw_params</type> data via
- alsa-lib. There are many fields copied from hw_params and
- sw_params structs. For example,
- <structfield>format</structfield> holds the format type
- chosen by the application. This field contains the enum value
- <constant>SNDRV_PCM_FORMAT_XXX</constant>.
- </para>
-
- <para>
- One thing to be noted is that the configured buffer and period
- sizes are stored in <quote>frames</quote> in the runtime.
- In the ALSA world, 1 frame = channels * samples-size.
- For conversion between frames and bytes, you can use the
- <function>frames_to_bytes()</function> and
- <function>bytes_to_frames()</function> helper functions.

- holds the physical address of the buffer. This field is

- You can override the former if you need to assign different data

- <title>Atomicity</title>
- <para>
- One of the most important (and thus difficult to debug) problems
- in kernel programming are race conditions.
- In the Linux kernel, they are usually avoided via spin-locks, mutexes
- or semaphores. In general, if a race condition can happen
- in an interrupt handler, it has to be managed atomically, and you
- have to use a spinlock to protect the critical session. If the
- critical section is not in interrupt handler code and
- if taking a relatively long time to execute is acceptable, you
- should use mutexes or semaphores instead.
- </para>
-
- <para>
- As already seen, some pcm callbacks are atomic and some are
- not. For example, the <parameter>hw_params</parameter> callback is
- non-atomic, while <parameter>trigger</parameter> callback is
- atomic. This means, the latter is called already in a spinlock
- held by the PCM middle layer. Please take this atomicity into
- account when you choose a locking scheme in the callbacks.
- </para>
-
- <para>
- In the atomic callbacks, you cannot use functions which may call
- <function>schedule</function> or go to
- <function>sleep</function>. Semaphores and mutexes can sleep,
- and hence they cannot be used inside the atomic callbacks
- (e.g. <parameter>trigger</parameter> callback).
- To implement some delay in such a callback, please use
- <function>udelay()</function> or <function>mdelay()</function>.
- </para>
-
- <para>
- All three atomic callbacks (trigger, pointer, and ack) are
- called with local interrupts disabled.

- <title>Constraints</title>
- <para>
- If your chip supports unconventional sample rates, or only the

- </para>
-
- <para>
- For example, in order to restrict the sample rates in the some
- supported values, use
- <function>snd_pcm_hw_constraint_list()</function>.
- You need to call this function in the open callback.

-
- <para>
- There are many different constraints.
- Look at <filename>sound/pcm.h</filename> for a complete list.
- You can even define your own constraint rules.
- For example, let's suppose my_chip can manage a substream of 1 channel
- if and only if the format is S16_LE, otherwise it supports any format
- specified in the <structname>snd_pcm_hardware</structname> structure (or in any
- other constraint_list). You can build a rule like this:
-

-<![CDATA[
- static int hw_rule_format_by_channels(struct snd_pcm_hw_params *params,

- }
- return 0;

-]]>
- </programlisting>

- The rule function is called when an application sets the number of

- <title>Definition of Controls</title>
- <para>
- To create a new control, you need to define the
- following three
- callbacks: <structfield>info</structfield>,
- <structfield>get</structfield> and
- <structfield>put</structfield>. Then, define a
- struct <structname>snd_kcontrol_new</structname> record, such as:

- </example>
- </para>
-
- <para>
- Most likely the control is created via
- <function>snd_ctl_new1()</function>, and in such a case, you can
- add the <parameter>__devinitdata</parameter> prefix to the
- definition as above.
- </para>
-
- <para>
- The <structfield>iface</structfield> field specifies the control
- type, <constant>SNDRV_CTL_ELEM_IFACE_XXX</constant>, which
- is usually <constant>MIXER</constant>.
- Use <constant>CARD</constant> for global controls that are not
- logically part of the mixer.
- If the control is closely associated with some specific device on
- the sound card, use <constant>HWDEP</constant>,
- <constant>PCM</constant>, <constant>RAWMIDI</constant>,
- <constant>TIMER</constant>, or <constant>SEQUENCER</constant>, and
- specify the device number with the
- <structfield>device</structfield> and
- <structfield>subdevice</structfield> fields.
- </para>
-
- <para>
- The <structfield>name</structfield> is the name identifier
- string. Since ALSA 0.9.x, the control name is very important,
- because its role is classified from its name. There are
- pre-defined standard control names. The details are described in
- the <link linkend="control-interface-control-names"><citetitle>
- Control Names</citetitle></link> subsection.
- </para>
-
- <para>
- The <structfield>index</structfield> field holds the index number
- of this control. If there are several different controls with
- the same name, they can be distinguished by the index
- number. This is the case when
- several codecs exist on the card. If the index is zero, you can
- omit the definition above.
- </para>
-
- <para>
- The <structfield>access</structfield> field contains the access
- type of this control. Give the combination of bit masks,

- the <link linkend="control-interface-access-flags"><citetitle>
- Access Flags</citetitle></link> subsection.
- </para>
-
- <para>
- The <structfield>private_value</structfield> field contains
- an arbitrary long integer value for this record. When using
- the generic <structfield>info</structfield>,
- <structfield>get</structfield> and
- <structfield>put</structfield> callbacks, you can pass a value
- through this field. If several small numbers are necessary, you can

- (casted to unsigned long) of some record to this field, too.
- </para>

- might be a part of its own PCI I/O region. It depends on the
- chip design.
- </para>
-
- <para>
- The 5th argument is a bitflag for additional information.

- <para>
- ALSA provides several different buffer allocation functions
- depending on the bus and the architecture. All these have a
- consistent API. The allocation of physically-contiguous pages is
- done via
- <function>snd_malloc_xxx_pages()</function> function, where xxx
- is the bus type.
- </para>
-
- <para>
- The allocation of pages with fallback is
- <function>snd_malloc_xxx_pages_fallback()</function>. This

- enough space is found.
- </para>
-
- <para>
- The release the pages, call
- <function>snd_free_xxx_pages()</function> function.
- </para>
-
- <para>
- Usually, ALSA drivers try to allocate and reserve
- a large contiguous physical space
- at the time the module is loaded for the later use.
- This is called <quote>pre-allocation</quote>.
- As already written, you can call the following function at
- pcm instance construction time (in the case of PCI bus).
-
- <informalexample>
- <programlisting>
-<![CDATA[

-]]>
- </programlisting>
- </informalexample>
-
- where <parameter>size</parameter> is the byte size to be
- pre-allocated and the <parameter>max</parameter> is the maximum
- size to be changed via the <filename>prealloc</filename> proc file.
- The allocator will try to get an area as large as possible
- within the given size.
- </para>
-
- <para>
- The second argument (type) and the third argument (device pointer)
- are dependent on the bus.
- In the case of the ISA bus, pass <function>snd_dma_isa_data()</function>
- as the third argument with <constant>SNDRV_DMA_TYPE_DEV</constant> type.
- For the continuous buffer unrelated to the bus can be pre-allocated
- with <constant>SNDRV_DMA_TYPE_CONTINUOUS</constant> type and the
- <function>snd_dma_continuous_data(GFP_KERNEL)</function> device pointer,
- where <constant>GFP_KERNEL</constant> is the kernel allocation flag to

- <section id="buffer-and-memory-external-hardware">
- <title>External Hardware Buffers</title>
- <para>
- Some chips have their own hardware buffers and the DMA
- transfer from the host memory is not available. In such a case,
- you need to either 1) copy/set the audio data directly to the
- external hardware buffer, or 2) make an intermediate buffer and
- copy/set the data from it to the external hardware buffer in
- interrupts (or in tasklets, preferably).
- </para>
-
- <para>
- The first case works fine if the external hardware buffer is large
- enough. This method doesn't need any extra buffers and thus is
- more effective. You need to define the
- <structfield>copy</structfield> and
- <structfield>silence</structfield> callbacks for
- the data transfer. However, there is a drawback: it cannot
- be mmapped. The examples are GUS's GF1 PCM or emu8000's
- wavetable PCM.
- </para>
-
- <para>
- The second case allows for mmap on the buffer, although you have
- to handle an interrupt or a tasklet to transfer the data
- from the intermediate buffer to the hardware buffer. You can find an
- example in the vxpocket driver.
- </para>
-
- <para>
- Another case is when the chip uses a PCI memory-map
- region for the buffer instead of the host memory. In this case,
- mmap is available only on certain architectures like the Intel one.
- In non-mmap mode, the data cannot be transferred as in the normal
- way. Thus you need to define the <structfield>copy</structfield> and
- <structfield>silence</structfield> callbacks as well,
- as in the cases above. The examples are found in
- <filename>rme32.c</filename> and <filename>rme96.c</filename>.
- </para>
-
- <para>
- The implementation of the <structfield>copy</structfield> and
- <structfield>silence</structfield> callbacks depends upon
- whether the hardware supports interleaved or non-interleaved
- samples. The <structfield>copy</structfield> callback is
- defined like below, a bit
- differently depending whether the direction is playback or
- capture:
-
- <informalexample>
- <programlisting>
-<![CDATA[
- static int playback_copy(struct snd_pcm_substream *substream, int channel,
- snd_pcm_uframes_t pos, void *src, snd_pcm_uframes_t count);
- static int capture_copy(struct snd_pcm_substream *substream, int channel,
- snd_pcm_uframes_t pos, void *dst, snd_pcm_uframes_t count);
-]]>
- </programlisting>
- </informalexample>
- </para>
-
- <para>
- In the case of interleaved samples, the second argument
- (<parameter>channel</parameter>) is not used. The third argument
- (<parameter>pos</parameter>) points the
- current position offset in frames.
- </para>
-
- <para>
- The meaning of the fourth argument is different between
- playback and capture. For playback, it holds the source data
- pointer, and for capture, it's the destination data pointer.
- </para>
-
- <para>
- The last argument is the number of frames to be copied.
- </para>
-
- <para>
- What you have to do in this callback is again different
- between playback and capture directions. In the
- playback case, you copy the given amount of data
- (<parameter>count</parameter>) at the specified pointer
- (<parameter>src</parameter>) to the specified offset
- (<parameter>pos</parameter>) on the hardware buffer. When
- coded like memcpy-like way, the copy would be like:
-
- <informalexample>
- <programlisting>
-<![CDATA[
- my_memcpy(my_buffer + frames_to_bytes(runtime, pos), src,
- frames_to_bytes(runtime, count));
-]]>
- </programlisting>
- </informalexample>
- </para>
-
- <para>
- For the capture direction, you copy the given amount of
- data (<parameter>count</parameter>) at the specified offset
- (<parameter>pos</parameter>) on the hardware buffer to the
- specified pointer (<parameter>dst</parameter>).
-
- <informalexample>
- <programlisting>
-<![CDATA[
- my_memcpy(dst, my_buffer + frames_to_bytes(runtime, pos),
- frames_to_bytes(runtime, count));
-]]>
- </programlisting>
- </informalexample>
-
- Note that both the position and the amount of data are given
- in frames.
- </para>
-
- <para>
- In the case of non-interleaved samples, the implementation
- will be a bit more complicated.
- </para>
-
- <para>
- You need to check the channel argument, and if it's -1, copy
- the whole channels. Otherwise, you have to copy only the
- specified channel. Please check
- <filename>isa/gus/gus_pcm.c</filename> as an example.
- </para>
-
- <para>
- The <structfield>silence</structfield> callback is also
- implemented in a similar way.
-
- <informalexample>
- <programlisting>
-<![CDATA[
- static int silence(struct snd_pcm_substream *substream, int channel,
- snd_pcm_uframes_t pos, snd_pcm_uframes_t count);
-]]>
- </programlisting>
- </informalexample>
- </para>
-
- <para>
- The meanings of arguments are the same as in the
- <structfield>copy</structfield>
- callback, although there is no <parameter>src/dst</parameter>
- argument. In the case of interleaved samples, the channel
- argument has no meaning, as well as on
- <structfield>copy</structfield> callback.
- </para>
-
- <para>
- The role of <structfield>silence</structfield> callback is to
- set the given amount
- (<parameter>count</parameter>) of silence data at the
- specified offset (<parameter>pos</parameter>) on the hardware
- buffer. Suppose that the data format is signed (that is, the
- silent-data is 0), and the implementation using a memset-like
- function would be like:
-
- <informalexample>
- <programlisting>
-<![CDATA[
- my_memcpy(my_buffer + frames_to_bytes(runtime, pos), 0,
- frames_to_bytes(runtime, count));
-]]>
- </programlisting>
- </informalexample>

- in the <structfield>hw_params</structfield> callback
- as well as in the case of normal PCI buffer.
- The SG-buffer handler will allocate the non-contiguous kernel
- pages of the given size and map them onto the virtually contiguous

- The physical address (runtime->dma_addr) is set to zero,
- because the buffer is physically non-contigous.
- The physical address table is set up in sgbuf->table.

- For the write callback, you can use

- <para>
- If the chip is supposed to work with suspend/resume
- functions, you need to add power-management code to the
- driver. The additional code for power-management should be
- <function>ifdef</function>'ed with
- <constant>CONFIG_PM</constant>.
- </para>
-
- <para>
- If the driver <emphasis>fully</emphasis> supports suspend/resume
- that is, the device can be
- properly resumed to its state when suspend was called,
- you can set the <constant>SNDRV_PCM_INFO_RESUME</constant> flag
- in the pcm info field. Usually, this is possible when the
- registers of the chip can be safely saved and restored to
- RAM. If this is set, the trigger callback is called with
- <constant>SNDRV_PCM_TRIGGER_RESUME</constant> after the resume
- callback completes.
- </para>
-
- <para>
- Even if the driver doesn't support PM fully but
- partial suspend/resume is still possible, it's still worthy to
- implement suspend/resume callbacks. In such a case, applications
- would reset the status by calling
- <function>snd_pcm_prepare()</function> and restart the stream
- appropriately. Hence, you can define suspend/resume callbacks
- below but don't set <constant>SNDRV_PCM_INFO_RESUME</constant>
- info flag to the PCM.
- </para>
-
- <para>
- Note that the trigger with SUSPEND can always be called when
- <function>snd_pcm_suspend_all</function> is called,
- regardless of the <constant>SNDRV_PCM_INFO_RESUME</constant> flag.
- The <constant>RESUME</constant> flag affects only the behavior
- of <function>snd_pcm_resume()</function>.
- (Thus, in theory,
- <constant>SNDRV_PCM_TRIGGER_RESUME</constant> isn't needed
- to be handled in the trigger callback when no
- <constant>SNDRV_PCM_INFO_RESUME</constant> flag is set. But,
- it's better to keep it for compatibility reasons.)
- </para>
- <para>
- In the earlier version of ALSA drivers, a common

- The driver needs to define the suspend/resume hooks according to

- So far, you've learned how to write the driver codes.
- And you might have a question now: how to put my own
- driver into the ALSA driver tree?
- Here (finally :) the standard procedure is described briefly.
- </para>
-
- <para>
- Suppose that you create a new PCI driver for the card
- <quote>xyz</quote>. The card module name would be
- snd-xyz. The new driver is usually put into the alsa-driver
- tree, <filename>alsa-driver/pci</filename> directory in
- the case of PCI cards.
- Then the driver is evaluated, audited and tested
- by developers and users. After a certain time, the driver
- will go to the alsa-kernel tree (to the corresponding directory,
- such as <filename>alsa-kernel/pci</filename>) and eventually
- will be integrated into the Linux 2.6 tree (the directory would be
- <filename>linux/sound/pci</filename>).
- </para>
-
- <para>
- In the following sections, the driver code is supposed
- to be put into alsa-driver tree. The two cases are covered:

Since 2.6.29 kernel, the driver has a more robust probing method, so
this error might happen rarely, though.
+On a machine with a broken BIOS, sometimes you need to force the
+driver to probe the codec slots the hardware doesn't report for use.
+In such a case, turn the bit 8 (0x100) of `probe_mask` option on.
+Then the rest 8 bits are passed as the codec slots to probe
+unconditionally. For example, `probe_mask=0x103` will force to probe
+the codec slots 0 and 1 no matter what the hardware reports.

+ writing to this file. Pass three numbers: nid, verb and parameter
+ (separated with a space).
hints::
- Shows hint strings for codec parsers for any use. Right now it's
- not used.
+ Shows / stores hint strings for codec parsers for any use.
+ Its format is `key = value`. For example, passing `hp_detect = yes`
+ to IDT/STAC codec parser will result in the disablement of the
+ headphone detection.
+init_pin_configs::
+ Shows the initial pin default config values set by BIOS.
+driver_pin_configs::
+ Shows the pin default values set by the codec parser explicitly.
+ This doesn't show all pin values but only the changed values by
+ the parser. That is, if the parser doesn't change the pin default
+ config values by itself, this will contain nothing.
+user_pin_configs::
+ Shows the pin default config values to override the BIOS setup.
+ Writing this (with two numbers, NID and value) appends the new
+ value. The given will be used instead of the initial BIOS value at
+ the next reconfiguration time. Note that this config will override
+ even the driver pin configs, too.
reconfig::
Triggers the codec re-configuration. When any value is written to
this file, the driver re-initialize and parses the codec tree
Resets the codec, removes the mixer elements and PCM stuff of the
specified codec, and clear all init verbs and hints.
+For example, when you want to change the pin default configuration
+value of the pin widget 0x14 to 0x9993013f, and let the driver
+re-configure based on that state, run like below:
+------------------------------------------------------------------------
+ # echo 0x14 0x9993013f > /sys/class/sound/hwC0D0/user_pin_configs
+ # echo 1 > /sys/class/sound/hwC0D0/reconfig
+------------------------------------------------------------------------
+
Power-Saving
~~~~~~~~~~~~
There are some other useful options. See `--help` option output for
details.
+When a probe error occurs or when the driver obviously assigns a
+mismatched model, it'd be helpful to load the driver with
+`probe_only=1` option (at best after the cold reboot) and run
+alsa-info at this state. With this option, the driver won't configure
+the mixer and PCM but just tries to probe the codec slot. After
+probing, the proc file is available, so you can get the raw codec
+information before modified by the driver. Of course, the driver
+isn't usable with `probe_only=1`. But you can continue the
+configuration via hwdep sysfs file if hda-reconfig option is enabled.

-** 5/2/94 Roman Hodek:
-** Added bi_atari part of the machine dependent union bi_un; for now it
-** contains just a model field to distinguish between TT and Falcon.
-** 26/7/96 Roman Zippel:
-** Renamed to setup.h; added some useful macros to allow gcc some
-** optimizations if possible.
-** 5/10/96 Geert Uytterhoeven:
-** Redesign of the boot information structure; moved boot information
-** structure to bootinfo.h

This allows you to specify the number of channels that the on-chip
DMAC supports. This will be 4 for SH7750/SH7751 and 8 for the
of the SH7760.
Say Y if you want to use Audio/USB DMA on your SH7760 board.

+ Selecting this will enable support for the PVR2 DMA controller.
+ As this chains off of the on-chip DMAC, that must also be
+ enabled by default.
+
+ This is primarily used by the pvr2fb framebuffer driver for

+ AES cipher algorithms (FIPS-197). AES uses the Rijndael
+ algorithm.
+
+ Rijndael appears to be consistently a very good performer in
+ both hardware and software across a wide range of computing
+ environments regardless of its use in feedback or non-feedback
+ modes. Its key setup time is excellent, and its key agility is
+ good. Rijndael's very low memory requirements make it very well
+ suited for restricted-space environments, in which it also
+ demonstrates excellent performance. Rijndael's operations are
+ among the easiest to defend against power and timing attacks.

Compiles debug level messages into the kernel, which would not
otherwise be available at runtime. These messages can then be
- enabled/disabled on a per module basis. This mechanism implicitly
- enables all pr_debug() and dev_dbg() calls. The impact of this
- compile option is a larger kernel text size of about 2%.
+ enabled/disabled based on various levels of scope - per source file,
+ function, module, format string, and line number. This mechanism
+ implicitly enables all pr_debug() and dev_dbg() calls. The impact of
+ this compile option is a larger kernel text size of about 2%.
Usage:
- Dynamic debugging is controlled by the debugfs file,
- dynamic_printk/modules. This file contains a list of the modules that
- can be enabled. The format of the file is the module name, followed
- by a set of flags that can be enabled. The first flag is always the
- 'enabled' flag. For example:
+ Dynamic debugging is controlled via the 'dynamic_debug/ddebug' file,
+ which is contained in the 'debugfs' filesystem. Thus, the debugfs
+ filesystem must first be mounted before making use of this feature.
+ We refer the control file as: <debugfs>/dynamic_debug/ddebug. This
+ file contains a list of the debug statements that can be enabled. The
+ format for each line of the file is:
- <module_name> <enabled=0/1>
- .
- .
- .
+ filename:lineno [module]function flags format
- <module_name> : Name of the module in which the debug call resides
- <enabled=0/1> : whether the messages are enabled or not
+ filename : source file of the debug statement
+ lineno : line number of the debug statement
+ module : module that contains the debug statement
+ function : function that contains the debug statement
+ flags : 'p' means the line is turned 'on' for printing
+ format : the format used for the debug statement
From a live system:
- snd_hda_intel enabled=0
- fixup enabled=0
- driver enabled=0
+ nullarbor:~ # cat <debugfs>/dynamic_debug/ddebug
+ # filename:lineno [module]function flags format
+ fs/aio.c:222 [aio]__put_ioctx - "__put_ioctx:\040freeing\040%p\012"
+ fs/aio.c:248 [aio]ioctx_alloc - "ENOMEM:\040nr_events\040too\040high\012"
+ fs/aio.c:1770 [aio]sys_io_cancel - "calling\040cancel\012"
- Enable a module:
+ Example usage:
- $echo "set enabled=1 <module_name>" > dynamic_printk/modules
+ // enable the message at line 1603 of file svcsock.c
+ nullarbor:~ # echo -n 'file svcsock.c line 1603 +p' >
+ <debugfs>/dynamic_debug/ddebug
- Disable a module:
+ // enable all the messages in file svcsock.c
+ nullarbor:~ # echo -n 'file svcsock.c +p' >
+ <debugfs>/dynamic_debug/ddebug
- $echo "set enabled=0 <module_name>" > dynamic_printk/modules
+ // enable all the messages in the NFS server module
+ nullarbor:~ # echo -n 'module nfsd +p' >
+ <debugfs>/dynamic_debug/ddebug
- Enable all modules:
+ // enable all 12 messages in the function svc_process()
+ nullarbor:~ # echo -n 'func svc_process +p' >
+ <debugfs>/dynamic_debug/ddebug
- $echo "set enabled=1 all" > dynamic_printk/modules
+ // disable all 12 messages in the function svc_process()
+ nullarbor:~ # echo -n 'func svc_process -p' >
+ <debugfs>/dynamic_debug/ddebug
- Disable all modules:
-
- $echo "set enabled=0 all" > dynamic_printk/modules
-
- Finally, passing "dynamic_printk" at the command line enables
- debugging for all modules. This mode can be turned off via the above
- disable command.

-/***************************************************************************************************
-*
-* To understand what Alsa Drivers should be doing look at "Writing an Alsa Driver" by Takashi Iwai
-* available in the Alsa doc section on the website
-*
-* A few notes to make things clearer. The UDA1341 is hooked up to Serial port 4 on the SA1100.
-* We are using SSP mode to talk to the UDA1341. The UDA1341 bit & wordselect clocks are generated
-* by this UART. Unfortunately, the clock only runs if the transmit buffer has something in it.
-* So, if we are just recording, we feed the transmit DMA stream a bunch of 0x0000 so that the
-* transmit buffer is full and the clock keeps going. The zeroes come from FLUSH_BASE_PHYS which
-* is a mem loc that always decodes to 0's w/ no off chip access.
-*
-* Some alsa terminology:
-* frame => num_channels * sample_size e.g stereo 16 bit is 2 * 16 = 32 bytes
-* period => the least number of bytes that will generate an interrupt e.g. we have a 1024 byte
-* buffer and 4 periods in the runtime structure this means we'll get an int every 256
-* bytes or 4 times per buffer.
-* A number of the sizes are in frames rather than bytes, use frames_to_bytes and
-* bytes_to_frames to convert. The easiest way to tell the units is to look at the
-* type i.e. runtime-> buffer_size is in frames and its type is snd_pcm_uframes_t
-*
-* Notes about the pointer fxn:
-* The pointer fxn needs to return the offset into the dma buffer in frames.
-* Interrupts must be blocked before calling the dma_get_pos fxn to avoid race with interrupts.
-*
-* Notes about pause/resume
-* Implementing this would be complicated so it's skipped. The problem case is:
-* A full duplex connection is going, then play is paused. At this point you need to start xmitting
-* 0's to keep the record active which means you cant just freeze the dma and resume it later you'd
-* need to save off the dma info, and restore it properly on a resume. Yeach!
-*
-* Notes about transfer methods:
-* The async write calls fail. I probably need to implement something else to support them?
-*

+ * 2002/06/30 Karsten Wiese:
+ * for now this is only used to build a pinnacle / fiji driver.
+ * the OSS parent of this code is designed to also support
+ * the multisound classic via the file msnd_classic.c.
+ * to make it easier for some brave heart to implemt classic
+ * support in alsa, i left all the MSND_CLASSIC tokens in this file.
+ * but for now this untested & undone.

+ *
+ * ripped from linux kernel 2.4.18 by Karsten Wiese.

+ *
+ * Turtle Beach MultiSound Sound Card Driver for Linux
+ * msnd_pinnacle.c / msnd_classic.c
+ *
+ * -- If MSND_CLASSIC is defined:

- * 2) Only I2C is supported, not SPI
- * 3) Only Master mode is supported, not Slave.
- * 4) The machine driver's 'startup' function must call
- * cs4270_set_dai_sysclk() with the value of MCLK.
- * 5) Only I2S and left-justified modes are supported
- * 6) Power management is not supported
- * 7) The only supported control is volume and hardware mute (if enabled)
+ * - Software mode is supported. Stand-alone mode is not supported.
+ * - Only I2C is supported, not SPI
+ * - Support for master and slave mode
+ * - The machine driver's 'startup' function must call
+ * cs4270_set_dai_sysclk() with the value of MCLK.
+ * - Only I2S and left-justified modes are supported
