Subject: [Intel-gfx] [CI 0/1] drm/i915: Disable pread/pwrite ioctl's for IGT testing
Date: Mon, 15 Mar 2021 20:49:06 -0700	[thread overview]
Message-ID: <cover.1615865509.git.ashutosh.dixit@intel.com> (raw)

FOR CI ONLY. PLEASE DON'T REVIEW.

The upstream guidance at this time is to start phasing out
pread/pwrite ioctl's, the rationale being (a) the functionality can be
done entirely in userspace with a combination of mmap + memcpy, and
(b) no existing user mode clients actually use the pread/pwrite
interface.

The plan is to phase out these ioctls for _new_ Gen12+ platforms. However,
since this patch is actually for CI and the real changes which need to be
validated are in IGT, in this patch we are disabling pread/pwrite for
existing Gen11 and Gen12 platforms. This will be changed once IGT changes
are validated and finalized.
