2021-07-15lib/ioctl_wrappers: drop gem_require_stolen_support()Lucas De Marchi
There is no such thing in the kernel as ioctl DRM_COMMAND_BASE + DRM_I915_GEM_GET_APERTURE returning a struct with stolen_total_size. So gem_total_stolen_size() always returns 0. Also there are no callers for gem_total_stolen_size(), except for gem_require_stolen_support() which is unused.

2021-03-17lib/ioctl_wrappers: Keep IGT working without pread/pwrite ioctlsAshutosh Dixit
The general direction at this time is to phase out pread/write ioctls and not support them in future products. This means IGT must handle the absence of these ioctls. This patch does this by modifying gem_read() and gem_write() to do the read/write using the pread/pwrite ioctls first but when these ioctls are unavailable fall back to doing the read/write using a combination of mmap and memcpy. Callers who must absolutely use the pread/pwrite ioctls (such as tests which test these ioctls or must otherwise only use the pread/pwrite ioctls) must use gem_require_pread_pwrite() to skip when these ioctls are not available. v1: Removed __gem_pread, gem_pread, __gem_pwrite and gem_pwrite introduced previously since they are not necessary, gem_require_pread_pwrite is sufficient v2: Fix CI failures in gem_advise and gen9_exec_parse by introducing gem_require_pread_pwrite v3: Skip mmap for 0 length read/write's v4: Remove redundant igt_assert's v5: Re-run v6: s/EOPNOTSUPP/-EOPNOTSUPP/ v7: Rebase on latest master, skip gem_exec_parallel@userptr with gem_require_pread_pwrite v8: Re-run v9: Rebase Acked-by: Dave Airlie <airlied@redhat.com> Acked-by: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Reviewed-by: Zbigniew Kempczyński <zbigniew.kempczynski@intel.com> Signed-off-by: Ashutosh Dixit <ashutosh.dixit@intel.com>
