accel/ivpu: Improve buffer object logging

- Fix missing alloc log when drm_gem_handle_create() fails in
  drm_vma_node_allow() and open callback is not called
- Add ivpu_bo->ctx_id that enables to log the actual context
  id instead of using 0 as default
- Add couple WARNs and errors so we can catch more memory
  corruption issues

dummycon: Trigger redraw when switching consoles with deferred takeover

Signal vt subsystem to redraw console when switching to dummycon
with deferred takeover enabled. Makes the console switch to fbcon
and displays the available output.

With deferred takeover enabled, dummycon acts as the placeholder
until the first output to the console happens. At that point, fbcon
takes over. If the output happens while dummycon is not active, it
cannot inform fbcon. This is the case if the vt subsystem runs in
graphics mode.

A typical graphical boot starts plymouth, a display manager and a
compositor; all while leaving out dummycon. Switching to a text-mode
console leaves the console with dummycon even if a getty terminal
has been started.

Returning true from dummycon's con_switch helper signals the vt
subsystem to redraw the screen. If there's output available dummycon's
con_putc{s} helpers trigger deferred takeover of fbcon, which sets a
display mode and displays the output. If no output is available,
dummycon remains active.

drm/scheduler: signal scheduled fence when kill job

When an entity from application B is killed, drm_sched_entity_kill()
removes all jobs belonging to that entity through
drm_sched_entity_kill_jobs_work(). If application A's job depends on a
scheduled fence from application B's job, and that fence is not properly
signaled during the killing process, application A's dependency cannot be
cleared.

This leads to application A hanging indefinitely while waiting for a
dependency that will never be resolved. Fix this issue by ensuring that
scheduled fences are properly signaled when an entity is killed, allowing
dependent applications to continue execution.

drm/tiny: panel-mipi-dbi: Use drm_client_setup_with_fourcc()

Since commit 559358282e5b ("drm/fb-helper: Don't use the preferred depth
for the BPP default"), RGB565 displays such as the CFAF240320X no longer
render correctly: colors are distorted and the content is shown twice
horizontally.

This regression is due to the fbdev emulation layer defaulting to 32 bits
per pixel, whereas the display expects 16 bpp (RGB565). As a result, the
framebuffer data is incorrectly interpreted by the panel.

Fix the issue by calling drm_client_setup_with_fourcc() with a format
explicitly selected based on the display's bits-per-pixel value. For 16
bpp, use DRM_FORMAT_RGB565; for other values, fall back to the previous
behavior. This ensures that the allocated framebuffer format matches the
hardware expectations, avoiding color and layout corruption.

Tested on a CFAF240320X display with an RGB565 configuration, confirming
correct colors and layout after applying this patch.

drm/v3d: Add job to pending list if the reset was skipped

When a CL/CSD job times out, we check if the GPU has made any progress
since the last timeout. If so, instead of resetting the hardware, we skip
the reset and let the timer get rearmed. This gives long-running jobs a
chance to complete.

However, when `timedout_job()` is called, the job in question is removed
from the pending list, which means it won't be automatically freed through
`free_job()`. Consequently, when we skip the reset and keep the job
running, the job won't be freed when it finally completes.

This situation leads to a memory leak, as exposed in [1] and [2].

Similarly to commit 704d3d60fec4 ("drm/etnaviv: don't block scheduler when
GPU is still active"), this patch ensures the job is put back on the
pending list when extending the timeout.

no concern about having to transform any data, so the dbidev pixel
format is always used for calculating the length.

Calling drm_crtc_vblank_on() drm_crtc_helper_funcs' atomic_enable is
expected to enable vblank interrupts. It may have been avoided here to
due to drm_crtc_vblank_get()'s error behavior after
drm_crtc_vblank_reset(). With that fixed in the preceding change the
driver can call drm_crtc_vblank_on() from adp_crtc_atomic_enable().

drm: adp: Handle drm_crtc_vblank_get() errors

drm_crtc_vblank_get() may fail when it's called before
drm_crtc_vblank_on() on a resetted CRTC. This occurs in
drm_crtc_helper_funcs' atomic_flush() calls after
drm_atomic_helper_crtc_reset() for example directly after probe. Send
the vblank event directly in such cases. Avoids following warning in
the subsequent drm_crtc_vblank_put() call from the vblank irq handler as
below:

Modifying `crtc->state->event` here is fine as crtc->mutex is locked by

drm/nouveau: Fix WARN_ON in nouveau_fence_context_kill()

Nouveau is mostly designed in a way that it's expected that fences only
ever get signaled through nouveau_fence_signal(). However, in at least
one other place, nouveau_fence_done(), can signal fences, too. If that
happens (race) a signaled fence remains in the pending list for a while,
until it gets removed by nouveau_fence_update().

Should nouveau_fence_context_kill() run in the meantime, this would be
a bug because the function would attempt to set an error code on an
already signaled fence.

Have nouveau_fence_context_kill() check for a fence being signaled.

drm: panel: jd9365da: fix reset signal polarity in unprepare

commit a8972d5a49b4 ("drm: panel: jd9365da-h3: fix reset signal polarity")
fixed reset signal polarity in jadard_dsi_probe() and jadard_prepare().

It was not done in jadard_unprepare() because of an incorrect assumption
about reset line handling in power off mode. After looking into the
datasheet, it now appears that before disabling regulators, the reset line
is deasserted first, and if reset_before_power_off_vcioo is true, then the
reset line is asserted.

drm/meson: use unsigned long long / Hz for frequency types

Christian reports that 4K output using YUV420 encoding fails with the
following error:
  Fatal Error, invalid HDMI vclk freq 593406

Modetest shows the following:
  3840x2160 59.94 3840 4016 4104 4400 2160 2168 2178 2250 593407 flags: xxxx, xxxx,
  drm calculated value -------------------------------------^

This indicates that there's a (1kHz) mismatch between the clock
calculated by the drm framework and the meson driver.

Relevant function call stack:
(drm framework)
  -> meson_encoder_hdmi_atomic_enable()
    -> meson_encoder_hdmi_set_vclk()
      -> meson_vclk_setup()

The video clock requested by the drm framework is 593407kHz. This is
passed by meson_encoder_hdmi_atomic_enable() to
meson_encoder_hdmi_set_vclk() and the following formula is applied:
- the frequency is halved (which would be 296703.5kHz) and rounded down
  to the next full integer, which is 296703kHz
- TMDS clock is calculated (296703kHz * 10)
- video encoder clock is calculated - this needs to match a table from
  meson_vclk.c and so it doubles the previously halved value again
  (resulting in 593406kHz)
- meson_vclk_setup() can't find (either directly, or by deriving it from
  594000kHz * 1000 / 1001 and rounding to the closest integer value -
  which is 593407kHz as originally requested by the drm framework) a
  matching clock in it's internal table and errors out with "invalid
  HDMI vclk freq"

Fix the division precision by switching the whole meson driver to use
unsigned long long (64-bit) Hz values for clock frequencies instead of
unsigned int (32-bit) kHz to fix the rouding error.

Fix the frequency returned to the user space by

The kernel driver returned CPU frequency for MTL and bare
PLL frequency for LNL - this was inconsistent and incorrect
for both platforms. With this fix the driver returns maximum
frequency of the NPU data processing unit (DPU) for all HW
generations. This is what user space always expected.

Also do not set CPU frequency in boot params - the firmware
does not use frequency passed from the driver, it was only
used by the early pre-production firmware.
With that we can remove CPU frequency calculation code.

This commit is a resubmission of commit 1fe1c66274fb ("drm/v3d: Fix

accidentally reverted by commit 91dae758bdb8 ("Merge tag

From the original commit message:

```
`args->cfg[4]` is configured in Indirect Dispatch using the number of
batches. Currently, for all V3D tech versions, `args->cfg[4]` equals the
number of batches subtracted by 1. But, for V3D 7.1.6 and later, we must not

drm/tests: helpers: Create kunit helper to destroy a drm_display_mode

A number of test suites call functions that expect the returned
drm_display_mode to be destroyed eventually.

However, none of the tests called drm_mode_destroy, which results in a
memory leak.

Since drm_mode_destroy takes two pointers as argument, we can't use a
kunit wrapper. Let's just create a helper every test suite can use.

Disable SLUB_TINY for build testing

... and don't error out so hard on missing module descriptions.

Before commit 6c6c1fc09de3 ("modpost: require a MODULE_DESCRIPTION()")
we used to warn about missing module descriptions, but only when
building with extra warnigns (ie 'W=1').

After that commit the warning became an unconditional hard error.

And it turns out not all modules have been converted despite the claims
to the contrary.  As reported by Damian Tometzki, the slub KUnit test
didn't have a module description, and apparently nobody ever really
noticed.

The reason nobody noticed seems to be that the slub KUnit tests get
disabled by SLUB_TINY, which also ends up disabling a lot of other code,
both in tests and in slub itself.  And so anybody doing full build tests
didn't actually see this failre.

So let's disable SLUB_TINY for build-only tests, since it clearly ends
up limiting build coverage.  Also turn the missing module descriptions
error back into a warning, but let's keep it around for non-'W=1'
builds.

tools/power turbostat: Increase CPU_SUBSET_MAXCPUS to 8192

On systems with >= 1024 cpus (in my case 1152), turbostat fails with the error output:
"turbostat: /sys/fs/cgroup/cpuset.cpus.effective: cpu str malformat 0-1151"

A similar error appears with the use of turbostat --cpu when the inputted cpu
range contains a cpu number >= 1024:
# turbostat -c 1100-1151
"--cpu 1100-1151" malformed
...

Both errors are caused by parse_cpu_str() reaching its limit of CPU_SUBSET_MAXCPUS.

It's a good idea to limit the maximum cpu number being parsed, but 1024 is too low.
For a small increase in compute and allocated memory, increasing CPU_SUBSET_MAXCPUS
brings support for parsing cpu numbers >= 1024.

Increase CPU_SUBSET_MAXCPUS to 8192, a common setting for CONFIG_NR_CPUS on x86_64.

"A set of updates for the interrupt subsystem:

   - A treewide cleanup for the irq_domain code, which makes the naming

     This is a trivial mechanical change and is done late to ensure that
     all instances have been catched and new code merged post rc1 wont
     reintroduce new instances.

   - A trivial consistency fix in the migration code

     The recent introduction of irq_force_complete_move() in the core
     code, causes a problem for the nostalgia crowd who maintains ia64
     out of tree.

     The code assumes that hierarchical interrupt domains are enabled
     and dereferences irq_data::parent_data unconditionally. That works
     in mainline because both architectures which enable that code have
     hierarchical domains enabled. Though it breaks the ia64 build,
     which enables the functionality, but does not have hierarchical
     domains.

     While it's not really a problem for mainline today, this
     unconditional dereference is inconsistent and trivially fixable by
     using the existing helper function irqd_get_parent_data(), which
     has the appropriate #ifdeffery in place"

Pull timer fix from Thomas Gleixner:
"A revert to fix a adjtimex() regression:

  The recent change to prevent that time goes backwards for the coarse
  time getters due to immediate multiplier adjustments via adjtimex(),
  changed the way how the timekeeping core treats that.

  That change result in a regression on the adjtimex() side, which is
  user space visible:

   1) The forwarding of the base time moves the update out of the
      original period and establishes a new one. That's changing the
      behaviour of the [PF]LL control, which user space expects to be
      applied periodically.

   2) The clearing of the accumulated NTP error due to #1, changes the
      behaviour as well.

  An attempt to delay the multiplier/frequency update to the next tick
  did not solve the problem as userspace expects that the multiplier or
  frequency updates are in effect, when the syscall returns.

  There is a different solution for the coarse time problem available,
  so revert the offending commit to restore the existing adjtimex()
  behaviour"

kbuild: rpm-pkg: build a debuginfo RPM

The rpm-pkg make target currently suffers from a few issues related to
debuginfo:
1. debuginfo for things built into the kernel (vmlinux) is not available
   in any RPM produced by make rpm-pkg. This makes using tools like
   systemtap against a make rpm-pkg kernel impossible.
2. debug source for the kernel is not available. This means that
   commands like 'disas /s' in gdb, which display source intermixed with
   assembly, can only print file names/line numbers which then must be
   painstakingly resolved to actual source in a separate editor.
3. debuginfo for modules is available, but it remains bundled with the
   .ko files that contain module code, in the main kernel RPM. This is a
   waste of space for users who do not need to debug the kernel (i.e.
   most users).

Address all of these issues by additionally building a debuginfo RPM
when the kernel configuration allows for it, in line with standard
patterns followed by RPM distributors. With these changes:
1. systemtap now works (when these changes are backported to 6.11, since
   systemtap lags a bit behind in compatibility), as verified by the
   following simple test script:

   # stap -e 'probe kernel.function("do_sys_open").call { printf("%s\n", $$parms); }'
   dfd=0xffffffffffffff9c filename=0x7fe18800b160 flags=0x88800 mode=0x0
   ...

2. disas /s works correctly in gdb, with source and disassembly
   interspersed:

   # gdb vmlinux --batch -ex 'disas /s blk_op_str'
   Dump of assembler code for function blk_op_str:
   block/blk-core.c:
   125     {
      0xffffffff814c8740 <+0>:     endbr64

   127

3. The size of the main kernel package goes down substantially,
   especially if many modules are built (quite typical). Here is a
   comparison of installed size of the kernel package (configured with
   allmodconfig, dwarf4 debuginfo, and module compression turned off)
   before and after this patch:

   # rpm -qi kernel-6.13* | grep -E '^(Version|Size)'
   Version     : 6.13.0postpatch+
   Size        : 1382874089
   Version     : 6.13.0prepatch+
   Size        : 17870795887

   This is a ~92% size reduction.

Note that a debuginfo package can only be produced if the following
configs are set:
- CONFIG_DEBUG_INFO=y
- CONFIG_MODULE_COMPRESS=n
- CONFIG_DEBUG_INFO_SPLIT=n

The first of these is obvious - we can't produce debuginfo if the build
does not generate it. The second two requirements can in principle be
removed, but doing so is difficult with the current approach, which uses
a generic rpmbuild script find-debuginfo.sh that processes all packaged
executables. If we want to remove those requirements the best path
forward is likely to add some debuginfo extraction/installation logic to
the modules_install target (controllable by flags). That way, it's
easier to operate on modules before they're compressed, and the logic
can be reused by all packaging targets.

kconfig: merge_config: use an empty file as initfile

The scripts/kconfig/merge_config.sh script requires an existing
$INITFILE (or the $1 argument) as a base file for merging Kconfig
fragments. However, an empty $INITFILE can serve as an initial starting
point, later referenced by the KCONFIG_ALLCONFIG Makefile variable
if -m is not used. This variable can point to any configuration file
containing preset config symbols (the merged output) as stated in
Documentation/kbuild/kconfig.rst. When -m is used $INITFILE will
contain just the merge output requiring the user to run make (i.e.
KCONFIG_ALLCONFIG=<$INITFILE> make <allnoconfig/alldefconfig> or make
olddefconfig).

Instead of failing when `$INITFILE` is missing, create an empty file and
use it as the starting point for merges.

nios2: migrate to the generic rule for built-in DTB

Commit 654102df2ac2 ("kbuild: add generic support for built-in boot

Select GENERIC_BUILTIN_DTB when built-in DTB support is enabled.

To keep consistency across architectures, this commit also renames

sh: Align .bss section padding to 8-byte boundary

J2-based devices expect to find a device tree blob at the end of the
.bss section. As of a77725a9a3c5 ("scripts/dtc: Update to upstream
version v1.6.1-19-g0a3a9d3449c8"), libfdt enforces 8-byte alignment
for the DTB, causing J2 devices to fail early in sh_fdt_init().

As the J2 loader firmware calculates the DTB location based on the kernel
image .bss section size rather than the __bss_stop symbol offset, the
required alignment can't be enforced with BSS_SECTION(0, PAGE_SIZE, 8).

To fix this, inline a modified version of the above macro which grows
.bss by the required size. While this change affects all existing SH
boards, it should be benign on platforms which don't need this alignment.

Revert "timekeeping: Fix possible inconsistencies in _COARSE clockids"

This reverts commit 757b000f7b936edf79311ab0971fe465bbda75ea.

Miroslav reported that the changes for handling the inconsistencies in the
coarse time getters result in a regression on the adjtimex() side.

There are two issues:

  1) The forwarding of the base time moves the update out of the original
     period and establishes a new one.

  2) The clearing of the accumulated NTP error is changing the behaviour as
     well.

Userspace expects that multiplier/frequency updates are in effect, when the
syscall returns, so delaying the update to the next tick is not solving the
problem either.

Revert the change, so that the established expectations of user space
implementations (ntpd, chronyd) are restored. The re-introduced
inconsistency of the coarse time getters will be addressed in a subsequent
fix.

genirq/migration: Use irqd_get_parent_data() in irq_force_complete_move()

Frank reported, that the common irq_force_complete_move() breaks the out of
tree build of ia64. The reason is that ia64 uses the migration code, but
does not have hierarchical interrupt domains enabled.

This went unnoticed in mainline as both x86 and RISC-V have hierarchical
domains enabled. Not that it matters for mainline, but it's still
inconsistent.

Use irqd_get_parent_data() instead of accessing the parent_data field
directly. The helper returns NULL when hierarchical domains are disabled
otherwise it accesses the parent_data field of the domain.

No functional change.
