Hi Dave, Sima,

Here is the main pull request for drm-intel-gt-next targeting 6.11.

First is the new userspace API for allowing upload of custom context
state used for replaying GPU hang error state captures. This will be
used by Mesa (see
https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/27594) for
debugging GPU hangs captured in the wild on real hardware. So far that
was only possible under simulation and that via some hacks. Also,
simulation in general has certain limitations to what hangs it can
reproduce. As the UAPI it is intended for Mesa developers only, it is
hidden behind a kconfig and runtime enablement switches.

Then there are fixes for hangs on Meteorlake due incorrect reduced CCS
configuration and a missing video engine workaround. Then fixes for a
couple race conditions in multi GT and breadcrumb handling, and a more
robust functional level reset by extending the timeout used.

A couple tiny cleanups here and there and finally one back-merge which
was required to land some display code base refactoring.

Regards,

Tvrtko

Hi Dave, Sima,

Here goes the final drm-intel-gt-next pull request for 6.19. It contains
one locking fix for Cherryview/Broxton with VT-D enabled, one making use
of a more canonical driver API, and a couple of selftest cleanups.

Hi Dave, Sima,

First drm-intel-gt-next pull request for 6.19 with only small fixups
relating to pwrite error code handling, GuC engine busyness reporting and
GuC reset handling. Plus a typo and a selftest fix.

One cross merge to synchronise the branches.

Hi Dave & Sima,

Here goes the first drm-intel-gt-next PR towards v6.18.

No new features, more of a -fixes PR this time.

Workaround fixes for older platforms, one overflow fix and an
cmpxchg optimization for x86 platforms.

Then the usual set of selftest improvements, smaller fixes and cleanups.

Regards, Joonas

Hi Dave, Sima,

Here comes the first pull request for 6.17.

Headline feature is that Ville was able to move DG1 out of force probe.
Other than that mostly fixes in the GuC backend.

One cross-merge to fix the build.

Hi Dave & Sima,

Here goes the drm-intel-gt-next PR towards 6.16. No new features, just fixes.

SLPC wait boost fix for DG1/DG2, engine reset fix for HSW.
Move to usleep_range for <20ms timeouts and fix splats on early probe
errors.

The rest is usual cleanups and improvements to selftests.

Regards, Joonas

Hi Dave, Sima,

Here comes the final pull request for 6.15.

Main thing is the bump of the reported mmap ioctl feature level, which
enables Mesa to reliably detect full partial mmap support. Then the DRM
client implementation gains vmap support and the remaining changes are just
some refactors and cleanups.

Regards,

Tvrtko

Hi Dave, Sima,

Here comes the main pull request for 6.15.

New sysfs UAPI for configuring the GuC power profiles is probably the most
interesting addition. Other than that, there is one performance workaround
for Gen12 platforms and a bunch of fixes, mostly around the GuC code. PMU
code was consolidated to use kernel facility for CPU hotplug handling which
required a merge during the development window.

Other than those just a collection of cleanups and selftest fixes.

Regards,

Tvrtko

Hi Dave & Sima,

Here goes the post-Holidays drm-intel-gt-next PR towards kernel 6.14 as
promised.

There is an engine reset improvement for Haswell (Gen7.5) and older platforms
and the rest is smaller fixes and dead code removal.

Hi Dave & Sima,

Here goes the pre-holidays drm-intel-gt-next PR towards 6.14 as promised.

As the main improvement there is engine busyness accuracy improvements
for GuC submission platforms and fixup for BO mapping corner cases.

The rest is smaller refactoring and improvements.

Happy Holidays!

Hi Dave, Sima,

This is the main pull request for 6.13 merge window.

PXP GuC auto-teardown feature got enabled, GPU reset robustness improvement
for Haswell and basic PMU functionality was enabled for Gen2 platforms.

The rest is a handful of small cleanups.

Regards,

Tvrtko

Hi Dave & Sima,

Here goes the final drm-intel-gt-next towards 6.12.

Primarily addition of fan speed hwmon, W/A fixups for ARL, add missing register

Hi Dave & Sima,

Mostly fixes in this drm-intel-gt-next PR at this time.

One thing to pay attention is the limitation of number of relocations to
INT_MAX which might impact synthetic tests, but no real workloads.

Regards, Joonas

***

drm-intel-gt-next-2024-08-23:

UAPI Changes:

- drm/i915: 2 GiB of relocations ought to be enough for anybody*

  Limit the number of relocations to INT_MAX.

  Only impact should be onsynthetic tests.

Driver Changes:

- Fix for #11396: GPU Hang and rcs0 reset on Cherrytrail platform
- Fix Virtual Memory mapping boundaries calculation (Andi)
- Fix for #11255: Long hangs in buddy allocator with DG2/A380 without
  Resizable BAR since 6.9 (David)
- Mark the GT as dead when mmio is unreliable (Chris, Andi)
- Workaround additions / fixes for MTL, ARL and DG2 (John H, Nitin)

Hi Dave, Sima,

The final pull for 6.11 is quite small and only contains a handful of
fixes in areas such as stolen memory probing on ATS-M, GuC priority
handling, out of memory reporting noise downgrade and fence register
hanlding race condition reported by CI.

Regards,

Tvrtko

Hi Dave & Sima,

Here's the drm-intel-gt-next PR for v6.10 in one shot.

We are adding a new uAPI for Mesa to request higher GT frequency for
compute contexts on GuC platform.

Then there is a W/A for DG2 to move to fixed CCS load balancing and
make all DG2 SKUs appear with single CCS with all the EUs attached by
default. Read more below under "UAPI Changes". There is one reported
regression against it which we're working on resolving, so expect to
see -next-fixes shortly once that happens.

Beyond that we have a bunch of workaround updates/fixes, fix for UAF
that has been hunted down for a while, GT reset fix for platforms that
load GuC but don't submit via it, fix for execlists priority submission,
proper capture of EIR register on hang.

THe rest is usual code cleanups/refactoring and selftest fixes.

Regards, Joonas

drm-intel-gt-next-2024-04-26:

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:
