  1. drm/i915: Disable SAMPLER_STATE prefetching on all Gen11 steppings. 

    [ Upstream commit 248f883 ]

The Demand Prefetch workaround (binding table prefetching) only applies
to Icelake A0/B0.  But the Sampler Prefetch workaround needs to be
applied to all Gen11 steppings, according to a programming note in the
SARCHKMD documentation.

Using the Intel Gallium driver, I have seen intermittent failures in
the dEQP-GLES31.functional.copy_image.non_compressed.* tests.  After
applying this workaround, the tests reliably pass.

v2: Remove the overlap with a pre-production w/a

  2. drm/i915: Make sure cdclk is high enough for DP audio on VLV/CHV 

    [ Upstream commit a8f196a ]

On VLV/CHV there is some kind of linkage between the cdclk frequency
and the DP link frequency. The spec says:
"For DP audio configuration, cdclk frequency shall be set to
 meet the following requirements:
 DP Link Frequency(MHz) | Cdclk frequency(MHz)
 270                    | 320 or higher
 162                    | 200 or higher"

I suspect that would more accurately be expressed as
"cdclk >= DP link clock", and in any case we can express it like
that in the code because of the limited set of cdclk (200, 266,
320, 400 MHz) and link frequencies (162 and 270 MHz) we support.

Without this we can end up in a situation where the cdclk
is too low and enabling DP audio will kill the pipe. Happens
eg. with 2560x1440 modes where the 266MHz cdclk is sufficient
to pump the pixels (241.5 MHz dotclock) but is too low for
the DP audio due to the link frequency being 270 MHz.

v2: Spell out the cdclk and link frequencies we actually support

  3. drm/i915: Support flags in whitlist WAs 

    [ Upstream commit 6883eab274813d158bfcfb499aa225ece61c0f29 ]

Newer hardware adds flags to the whitelist work-around register. These
allow per access direction privileges and ranges.

  4. drm/i915: Support whitelist workarounds on all engines 

    [ Upstream commit ebd2de4 ]

Newer hardware requires setting up whitelists on engines other than
render. So, extend the whitelist code to support all engines.

  5. drm/i915: whitelist PS_(DEPTH|INVOCATION)_COUNT 

    [ Upstream commit 6ce5bfe ]

CFL:C0+ changed the status of those registers which are now
blacklisted by default.

This is breaking a number of CTS tests on GL & Vulkan :

  KHR-GL45.pipeline_statistics_query_tests_ARB.functional_fragment_shader_invocations (GL)

  dEQP-VK.query_pool.statistics_query.fragment_shader_invocations.* (Vulkan)

v2: Only use one whitelist entry (Lionel)

  6. drm/i915: Add whitelist workarounds for ICL 

    [ Upstream commit 7b3d406 ]

Updated whitelist table for ICL.

v2: Reduce changes to just those required for media driver until
the selftest can be updated to support the new features of the
other entries.

  7. drm/i915/icl: whitelist PS_(DEPTH|INVOCATION)_COUNT 

    [ Upstream commit cf8f9aa ]

The same tests failing on CFL+ platforms are also failing on ICL.
Documentation doesn't list the
WaAllowPMDepthAndInvocationCountAccessFromUMD workaround for ICL but
applying it fixes the same tests as CFL.

v2: Use only one whitelist entry (Lionel)
