We missed setting the CCS mode during resume and engine resets.
Create a workaround to be added in the engine's workaround list.
This workaround sets the XEHP_CCS_MODE value at every reset.
The issue can be reproduced by running:
$ clpeak --kernel-latency
Without resetting the CCS mode, we encounter a fence timeout:
Fence expiration time out i915-0000:03:00.0:clpeak[2387]:2!

UAPI Changes:
- drm/i915/guc: Use context hints for GT frequency
Allow user to provide a low latency context hint. When set, KMD
sends a hint to GuC which results in special handling for this
context. SLPC will ramp the GT frequency aggressively every time
it switches to this context. The down freq threshold will also be
lower so GuC will ramp down the GT freq for this context more slowly.
We also disable waitboost for this context as that will interfere with
the strategy.
We need to enable the use of SLPC Compute strategy during init, but
it will apply only to contexts that set this bit during context
creation.
Userland can check whether this feature is supported using a new param-
I915_PARAM_HAS_CONTEXT_FREQ_HINT. This flag is true for all guc submission
enabled platforms as they use SLPC for frequency management.
The Mesa usage model for this flag is here -
https://gitlab.freedesktop.org/sushmave/mesa/-/commits/compute_hint
- drm/i915/gt: Enable only one CCS for compute workload
Enable only one CCS engine by default with all the compute sices
allocated to it.
While generating the list of UABI engines to be exposed to the
user, exclude any additional CCS engines beyond the first
instance
***
NOTE: This W/A will make all DG2 SKUs appear like single CCS SKUs by
default to mitigate a hardware bug. All the EUs will still remain
usable, and all the userspace drivers have been confirmed to be able
to dynamically detect the change in number of CCS engines and adjust.
For the smaller percent of applications that get perf benefit from
letting the userspace driver dispatch across all 4 CCS engines we will
be introducing a sysfs control as a later patch to choose 4 CCS each
with 25% EUs (or 50% if 2 CCS).
NOTE: A regression has been reported at
https://gitlab.freedesktop.org/drm/i915/kernel/-/issues/10895
However Andi has been triaging the issue and we're closing in a fix
to the gap in the W/A implementation:

With dynamic load-balancing disabled on the compute side, there's no
reason left to enable WA 16015675438. Drop it from both PVC and DG2.
Note that this can be done because now the driver always set a fixed
partition of EUs during initialization via the ccs_mode configuration.
The flag to GuC is still needed because of 18020744125, so update
the comment accordingly.

Several workarounds are guarded by IS_MTL_GRAPHICS_STEP. However none
of these workarounds are actually tied to MTL as a platform; they only
relate to the Xe_LPG graphics IP, regardless of what platform it appears
in. At the moment MTL is the only platform that uses Xe_LPG with IP
versions 12.70 and 12.71, but we can't count on this being true in the
future. Switch these to use a new IS_GFX_GT_IP_STEP() macro instead
that is purely based on IP version. IS_GFX_GT_IP_STEP() is also
GT-based rather than device-based, which will help prevent mistakes
where we accidentally try to apply Xe_LPG graphics workarounds to the
Xe_LPM+ media GT and vice-versa.
v2:
- Switch to a more generic and shorter IS_GT_IP_STEP macro that can be
used for both graphics and media IP (and any other kind of GTs that
show up in the future).
v3:
- Switch back to long-form IS_GFX_GT_IP_STEP macro. (Jani)
- Move macro to intel_gt.h. (Andi)
v4:
- Build IS_GFX_GT_IP_STEP on top of IS_GFX_GT_IP_RANGE and
IS_GRAPHICS_STEP building blocks and name the parameters from/until
rather than begin/fixed. (Jani)
- Fix usage examples in comment.
v5:
- Tweak comment on macro. (Gustavo)

Although some of our Xe_LPG workarounds were already being applied based
on IP version correctly, others were matching on MTL as a base platform,
which is incorrect. Although MTL is the only platform right now that
uses Xe_LPG IP, this may not always be the case. If a future platform
re-uses this graphics IP, the same workarounds should be applied, even
if it isn't a "MTL" platform.
We were also incorrectly applying Xe_LPG workarounds/tuning to the
Xe_LPM+ media IP in one or two places; we should make sure that we don't
try to apply graphics workarounds to the media GT and vice versa where
they don't belong. A new helper macro IS_GT_IP_RANGE() is added to help
ensure this is handled properly -- it checks that the GT matches the IP
type being tested as well as the IP version falling in the proper range.
Note that many of the stepping-based workarounds are still incorrectly
checking for a MTL base platform; that will be remedied in a later
patch.
v2:
- Rework macro into a slightly more generic IS_GT_IP_RANGE() that can
be used for either GFX or MEDIA checks.
v3:
- Switch back to separate macros for gfx and media. (Jani)
- Move macro to intel_gt.h. (Andi)

Most of the context workarounds tweak masked registers, but not all. For
masked registers, when writing the value it's sufficient to just write
the wa->set_bits since that will take care of both the clr and set bits
as well as not overwriting other bits.
However there are some workarounds, the registers are non-masked. Up
until now the driver was simply emitting a MI_LOAD_REGISTER_IMM with the
set_bits to program the register via the GPU in the WA bb. This has the
side effect of overwriting the content of the register outside of bits
that should be set and also doesn't handle the bits that should be
cleared.
Kenneth reported that on DG2, mesa was seeing a weird behavior due to
the kernel programming of L3SQCREG5 in dg2_ctx_gt_tuning_init(). With
the GPU idle, that register could be read via intel_reg as 0x00e001ff,
but during a 3D workload it would change to 0x0000007f. So the
programming of that tuning was affecting more than the bits in
L3_PWM_TIMER_INIT_VAL_MASK. Matt Roper noticed the lack of rmw for the
context workarounds due to the use of MI_LOAD_REGISTER_IMM.
So, for registers that are not masked, read its value via mmio, modify
and then set it in the buffer to be written by the GPU. This should take
care in a simple way of programming just the bits required by the
tuning/workaround. If in future there are registers that involved that
can't be read by the CPU, a more complex approach may be required like
a) issuing additional instructions to read and modify; or b) scan the
golden context and patch it in place before saving it; or something
else. But for now this should suffice.
Scanning the context workarounds for all platforms, these are the
impacted ones with the respective registers
mtl: DRAW_WATERMARK
mtl/dg2: XEHP_L3SQCREG5, XEHP_FF_MODE2
ICL has some non-masked registers in the context workarounds:
GEN8_L3CNTLREG, IVB_FBC_RT_BASE and VB_FBC_RT_BASE_UPPER, but there
shouldn't be an impact. The first is already being manually read and the
other 2 are intentionally overwriting the entire register. Same
reasoning applies to GEN12_FF_MODE2: the WA is intentionally
overwriting all the bits to avoid a read-modify-write.
v2: Reword commit message wrt GEN12_FF_MODE2 and the changed behavior
on preparatory patches.
v3: Also skip reading if clear|set bits covers everything
