c8d225946a drm/i915: Kill last user of intel_context_create_request outside of selftests
Instead of using intel_context_create_request(), use intel_context_pin()
and i915_create_request directly.

Now all those calls are gone outside of selftests. :)

c33298cb34 drm/i915/tgl: Fix stepping WA matching
TGL made stepping a litte mess, workarounds refer to the stepping of
the IP(GT or Display) not of the GPU stepping so it would already
require the same solution as used in commit 96c5a15f9f39
("drm/i915/kbl: Fix revision ID checks").
But to make things even more messy it have a different IP stepping
mapping between SKUs and the same stepping revision of GT do not match
the same HW between TGL U/Y and regular TGL.

So it was required to have 2 different macros to check GT WAs while
for Display we are able to use just one macro that uses the right
revids table.

All TGL workarounds checked and updated accordingly.

v2:
- removed TODO to check if WA 14010919138 applies to regular TGL.
- fixed display stepping in regular TGL (Anusha)

96c5a15f9f drm/i915/kbl: Fix revision ID checks
We usually assume that increasing PCI device revision ID's translates to
newer steppings; macros like IS_KBL_REVID() that we use rely on this
behavior.  Unfortunately this turns out to not be true on KBL; the
newer device 2 revision ID's sometimes go backward to older steppings.
The situation is further complicated by different GT and display
steppings associated with each revision ID.

Let's work around this by providing a table to map the revision ID to
specific GT and display steppings, and then perform our comparisons on
the mapped values.

v2:
 - Move the kbl_revids[] array to intel_workarounds.c to avoid compiler
   warnings about an unused variable in files that don't call the
   macros (kernel test robot).

f52fa57ae7 drm/i915/rkl: Add initial workarounds
RKL and TGL share some general gen12 workarounds, but each platform also
has its own platform-specific workarounds.

v2:
 - Add Wa_1604555607 for RKL.  This makes RKL's ctx WA list identical to
   TGL's, so we'll have both functions call the tgl_ function for now;
   this workaround isn't listed for DG1 so we don't want to add it to
   the general gen12_ function.

As today those 2 WAs have different implementation between TGL and DG1
WA pages but checking the HSD it is clear that DG1 implementation
should be used for both, also to do so is easier as we just need to

d0ed510a8e drm/i915: Add Wa_1604278689:icl,ehl
The bspec description for this workaround tells us to program
0xFFFF_FFFF into both FBC_RT_BASE_ADDR_REGISTER_* registers, but we've
previously found that this leads to failures in CI.  Our suspicion is
that the failures are caused by this valid turning on the "address valid
bit" even though we're intentionally supplying an invalid address.
Experimentation has shown that setting all bits _except_ for the
RT_VALID bit seems to avoid these failures.

v2:
 - Mask off the RT_VALID bit.  Experimentation with CI trybot indicates
   that this is necessary to avoid reset failures on BCS.

v3:
 - Program RT_BASE before RT_BASE_UPPER so that the valid bit is turned
   off by the first write.  (Chris)

dbe748cd3a drm/i915/tgl: Don't treat unslice registers as masked
The UNSLICE_UNIT_LEVEL_CLKGATE and UNSLICE_UNIT_LEVEL_CLKGATE2 registers
that we update in a few engine workarounds are not masked registers
(i.e., we don't have to write a mask bit in the top 16 bits when
updating one of the lower 16 bits).  As such, these workarounds should
be applied via wa_write_or() rather than wa_masked_en()

v2:
 - Rebase

3551ff9287 drm/i915/gen11: Moving WAs to rcs_engine_wa_init()
This are register of render engine, so after a render reset those
would return to the default value and init_clock_gating() is not
called for single engine reset.
So here moving it rcs_engine_wa_init() that will guarantee that this
WAs will not be lost.

Wa_1608008084 is an additional WA that applies to writes on FF_MODE2
register. We can't read it back either from CPU or GPU. Since the other
bits should be 0, recommendation to handle Wa_1604555607 is to actually
just write the timer value.

Do a write only and don't try to read it, neither before or after
the WA is applied.
