2020-12-26windows: drop XP supportSitsofe Wheeler
Windows 2003 has been EOL since 2015 and Windows XP has been EOL since 2014. Technically fio hasn't been properly targetting XP anyway - (see 16d40a15783f9181d64082fc00a970dff485798f 'configure: be explicit about "XP" Windows API version'). - Strip out support for XP and change the documentation to no longer mention it - Stop targetting XP in the CI 32 bit build Next stop, Windows 7...

2020-03-01filesetup: fix win raw disk access and improve dir creation failure msgSitsofe Wheeler
The commit df18600fd06258b96ae6f6b530ecdff541c2a82d ("filesetup: fix directory creation issues") broke Windows raw/physical disk access because Windows doesn't consider a path that only consists of a namespace (such as the device namespace "\\.\" - see https://docs.microsoft.com/en-gb/windows/win32/fileio/naming-a-file?redirectedfrom=MSDN#namespaces for information on Windows' namespaces) to exist as a directory(!). Workaround the issue for raw devices by explicitly considering the device namespace subcomponent to always be valid. Further, intermediate path components in UNC paths or paths starting with a namespace might also not "exist" so introduce backwards scanning for the longest pre-existing directory to sidestep this. The function doing this is made available for non-windows platforms so a similar code path is used everywhere. Tests done: Windows: > ./fio.exe --name=dtest --thread --size=16k --rw=write ` --filename 'fio.tmp' > ./fio.exe --name=dtest --thread --size=16k --rw=write ` --filename '\\?\C\:\Windows\Temp\fio\fio.tmp' > Clear-Disk 1 -RemoveData -Confirm:$false # Destroys partition data! > ./fio.exe --name=dtest --thread --size=16k --rw=write ` --filename '\\.\PhysicalDrive1' > ./fio.exe --name=dtest --thread --size=16k --rw=write ` --filename '\fio.tmp' > ./fio.exe --name=dtest --thread --size=16k --rw=write ` --filename '\\LOCALHOST\Users\User\fio\fio.tmp' macOS: $ rm -rf /tmp/fio $ ./fio --name=dtest --size=16k --filename /tmp/fio/fio.tmp \ --rw=write Finally, change the directory creation error message to give a human error message rather than just an errno.

2018-03-27windows: target Windows 7 and add support for more than 64 CPUsSitsofe Wheeler
Introduce support for targeting the build to either Windows XP or Windows 7 (the default). When targeting Windows 7 this allows us to use the process group APIs which are required are required to support more than 64 CPUs. These changes mean if you want a Windows binary that supports versions of Windows below Windows 7/Windows Server 2008 R2 you will need to explicitly use the --target-win-ver=xp configure option at build time. Such builds will lack features (such as the ability to access CPUs beyond those in fio's default process group) that are dependent on recent Windows APIs.

2017-11-16os-windows: fix cpumask operationsRobert Elliott
Fix cpumask manipulation on (64-bit) Windows systems. cpus_allowed=nn values greater than 32 does not work, due to * the compiler not promoting expressions like "1 << cpu" to 64 bits * the clear function clearing the wrong bit (using "cpu - 1"), * the clear function using XOR to clear (which only works if the bit was previously set) * the check function returning a 64-bit value through a 32-bit return value Example problems (from extra debug prints): * setting CPU 32 really sets bit 0 (CPU 0) Set mask of 0000000000000000 to add 0000000000000001 (32) * setting CPU 63 really sets bit 31 (CPU 31) Set mask of 0000000000000000 to add 0000000080000000 (63) * clearing CPU 0 really clears bit 63 (CPU 63) Clear mask of 0000000055555555 to remove 8000000000000000 (0) * clearing CPU 2 really clears bit 2 (CPU 2) Clear mask of 0000000055555555 to remove 0000000000000002 (2) * checking claims CPU 32 is not in a mask of CPUs {32,34,36,38} for 0000005500000000 check if bit 32 is set ==> FALSE Tested with x86_64-w64-mingw32-gcc 6.4.0 from cygwin on a system with 64 CPU cores (all fitting in one Windows processor group).

2017-05-23Drop struct thread_data dependency from os headersTomohiro Kusumi
Since os/os.h is included by fio.h before other functions/structures are even defined, it's better for os/os*.h not to have dependency on those (in this case it's struct thread_data and duplicated td_fill_ rand_seeds() prototypes) unless really needed. os/os*.h are basically collections of small wrappers over syscalls/etc whose idea is similar but with difference interface among supported platforms, thus they normally don't need to have dependency on fio functions/structures, and in fact they're normally designed that way. This commit gets rid of struct thread_data argument from an inlined function init_random_state(), which was needed only to call another function td_fill_rand_seeds(td). This can simply be called from setup_random_seeds() after init_random_state() without making any functional difference. Also rename init_random_state() to init_random_seeds() as it only initializes random seeds now. With this commit, struct thread_data is completely gone from os/. struct fio_file is still there, but this is needed by Windows where the idea of fd differs from unix like in general.

2017-03-13Use ENOTSUP if OS doesn't support blkdev page cache invalidationTomohiro Kusumi
The return value of blockdev_invalidate_cache() has been platform dependent (some pretend success, others return EINVAL) while Linux is the only one actually supports this via Linux specific ioctl. This commit makes all the rest return a consistent value ENOTSUP, so __file_invalidate_cache() prints a blkdev invalidation failure message that is consistent and makes sense.

2016-07-27Make return value type of fio_getaffinity() consistentTomohiro Kusumi
Return type of fio_getaffinity() isn't consistent among supported OS. Windows and DragonFlyBSD return void while FreeBSD version is int. The default version for those that don't support is do{}while(0). Linux version is a macro for sched_getaffinity(2) which returns 0 on success and -1 otherwise, so others should basically follow that. Note that I haven't compiled this on Windows, but it shouldn't fail. Signed-off-by: Tomohiro Kusumi <kusumi.tomohiro@gmail.com> Signed-off-by: Jens Axboe <axboe@fb.com>

Bruce writes: SIGUSR1 isn't defined on Windows so I've defined it. Also, MSI packages need a version string of x.x.x.x where x is between 0 and 65535 so we can't include the git hash. It's easier just to go back to hard-coding the version for now, and I'll update it (and the product GUID) when I create a new package (it doesn't need checked in each time). Also, Cygwin doesn't like $(SHELL_PATH) but $(SHELL) seems to work - does $(SHELL) cause a problem on other platforms? Signed-off-by: Jens Axboe <axboe@kernel.dk>

2011-01-08Various fixes/updatesBruce Cran
- Update HOWTO to note that directio and fallocate don't work with ZFS on Solaris. Refactor the Makefile's to add CPPFLAGS and LIBS. - Add -fno-omit-frame-pointer from Linux Makefile to every platform - Change undefined $(ALL_CFLAGS) to $(CFLAGS) - Pass -std=gnu99, without which OS X fails to build. - Add -D__EXTENSIONS__ on Solaris since some functions we need are behind it. - Pull in <limits.h> in fio.c to get PTHREAD_STACK_MIN. - NetBSD doesn't define PTHREAD_STACK_MIN so set it to 4k in os-netbsd.h - If we have posix_fallocate don't error out if it fails during mutex and malloc operations since it will fail on Solaris with a ZFS filesystem. As I understand it these aren't performance-critical operations so do they need to be considered critical? - Remove fio_unused from os-* files since it's defined in fio.h and we don't really need it. - FreeBSD has an idprio command but not the API so don't claim it does. - OS X doesn't have the timer_* API so emulate it using setitimer/sigaction. - NetBSD and Solaris don't support CLOCK_MONOTONIC in timer_create so remove FIO_HAVE_CLOCK_MONOTONIC from their os-* files. I've noticed that a change I made a while ago to use fmin/fmax could cause issues on older OSes - I had a CD with NetBSD 5.0.2 and found they had only been implemented in 5.1 so I'm not sure if I should revert it.
