intel_gtt.h is indirectly included absolutely everywhere in the
driver. DBG() is too short a name. Rename it GTT_TRACE() after
GEM_TRACE().

The thread_global_copy subtest of the live migrate selftest creates a
large number of threads and waits 10ms for them all to start. This is
not enough time to wait for the threaded tasks to start, as some may
need to wait for additional ring space to be granted. Threads that do
so are at risk of getting stopped (signaled) in the middle of waiting
for additional space, which can result in ERESTARTSYS getting reported
erroneously by i915_request_wait.
Instead of waiting a flat 10ms for the threads to start, wait 10ms per
thread. This grants enough of a buffer for each thread to wait for
additional ring space when needed.

References to i915_requests may be trapped by userspace inside a
sync_file or dmabuf (dma-resv) and held indefinitely across different
proceses. To counter-act the memory leaks, we try to not to keep
references from the request past their completion.
On the other side on fence release we need to know if rq->engine

To make it possible extra bit has been added to rq->execution_mask,
for marking virtual engines.

Add FW definition and the matching override modparam.
The GSC FW has both a release version, based on platform and a rolling
counter, and a compatibility version, which is the one tracking
interface changes. Since what we care about is the interface, we use
the compatibility version in the binary names.
Same as with the GuC, a major version bump indicate a
backward-incompatible change, while a minor version bump indicates a
backward-compatible one, so we use only the former in the file name.

If GuC hits an internal error (and survives long enough to report it
to the KMD), it is basically toast and will stop until a GT reset and
subsequent GuC reload is performed. Previously, the KMD just printed
an error message and then waited for the heartbeat to eventually kick
in and trigger a reset (assuming the heartbeat had not been disabled).
Instead, force the reset immediately to guarantee that it happens and
to eliminate the very long heartbeat delay. The captured error state
is also more likely to be useful if captured at the time of the error
rather than many seconds later.
Note that it is not possible to trigger a reset from with the G2H
handler itself. The reset prepare process involves flushing
outstanding G2H contents. So a deadlock could result. Instead, the G2H
handler queues a worker thread to do the reset asynchronously.
v2: Flush the worker on suspend and shutdown. Add rate limiting to
prevent spam from a totally dead system (review feedback from Daniele).

Many of the IS_METEORLAKE conditions throughout the driver are supposed
to be checks for Xe_LPG and/or Xe_LPM+ IP, not for the MTL platform
specifically. Update those checks to ensure that the code will still
operate properly if/when these IP versions show up on future platforms.
v2:
- Update two more conditions (one for pg_enable, one for MTL HuC
compatibility).
v3:
- Don't change GuC/HuC compatibility check, which sounds like it truly
is specific to the MTL platform. (Gustavo)
- Drop a non-lineage workaround number for the OA timestamp frequency
workaround. (Gustavo)

Stepping-specific media behavior shouldn't be tied to MTL as a platform,
but rather specifically to the Xe_LPM+ IP. Future non-MTL platforms may
re-use this IP and will need to follow the exact same logic and apply
the same workarounds. IS_MTL_MEDIA_STEP() is dropped in favor of
IS_MEDIA_GT_IP_STEP, which checks the media IP version associated with a
specific IP and also ensures that we're operating on the media GT, not
the primary GT.
v2:
- Switch to the IS_GT_IP_STEP macro.
v3:
- Switch back to long-form IS_MEDIA_GT_IP_STEP. (Jani)
v4:
- Build IS_MEDIA_GT_IP_STEP on top of IS_MEDIA_GT_IP_RANGE and
IS_MEDIA_STEP building blocks and name the parameters from/until
rather than begin/fixed.. (Jani)
v5:
- Tweak macro comment wording. (Gustavo)
- Add a check to catch NULL gt in IS_MEDIA_GT_IP_RANGE; this allows it
to be used safely on i915->media_gt, which may be NULL on some
platforms. (Gustavo)

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:

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)

WA_22016122933 was recently applied to all MeteorLake engines, which is
simultaneously too broad (should only apply to Media engines) and too
specific (should apply to all platforms that use the same media engine
as MeteorLake). Correct this in cases where coherency settings are
modified.
There were also two additional places where the workaround was applied
unconditionally. The change was confirmed as necessary for all
platforms, so the workaround label was removed.

This should be done before the soft min/max frequencies are restored.
When we disable the "Ignore efficient frequency" flag, GuC does not
actually bring the requested freq down to RPn.
Specifically, this scenario-
- ignore efficient freq set to true
- reduce min to RPn (from efficient)
- suspend
- resume (includes GuC load, restore soft min/max, restore efficient freq)
- validate min freq has been resored to RPn
This will fail if we didn't first restore(disable, in this case) efficient
freq flag before setting the soft min frequency.
v2: Bring the min freq down to RPn when we disable efficient freq (Rodrigo)
Also made the change to set the min softlimit to RPn at init. Otherwise, we
were storing RPe there.

On MTL, if the GSC Proxy init flows haven't completed, submissions to the
GSC engine will fail. Those init flows are dependent on the mei's
gsc_proxy component that is loaded in parallel with i915 and a
worker that could potentially start after i915 driver init is done.
That said, all subsytems that access the GSC engine today does check
for such init flow completion before using the GSC engine. However,
selftests currently don't wait on anything before starting.
To fix this, add a waiter function at the start of __run_selftests
that waits for gsc-proxy init flows to complete. Selftests shouldn't
care if the proxy-init failed as that should be flagged elsewhere.
Difference from prior versions:
v7: - Change the fw status to INTEL_UC_FIRMWARE_LOAD_FAIL if the
proxy-init fails so that intel_gsc_uc_fw_proxy_get_status
catches it. (Daniele)
v6: - Add a helper that returns something more than a boolean
so we selftest can stop waiting if proxy-init hadn't
completed but failed (Daniele).
v5: - Move the call to __wait_gsc_proxy_completed from common
__run_selftests dispatcher to the group-level selftest
function (Trvtko).
- change the pr_info to pr_warn if we hit the timeout.
v4: - Remove generalized waiters function table framework (Tvrtko).
- Remove mention of CI-framework-timeout from comments (Tvrtko).
v3: - Rebase to latest drm-tip.
v2: - Based on internal testing, increase the timeout for gsc-proxy
specific case to 8 seconds.

We always assumed that a device might either have AUX or FLAT
CCS, but this is an approximation that is not always true, e.g.
PVC represents an exception.
Set the basis for future finer selection by implementing a
boolean gen12_needs_ccs_aux_inv() function that tells whether aux
invalidation is needed or not.
Currently PVC is the only exception to the above mentioned rule.
