  • 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
        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 -
    - 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
        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
        However Andi has been triaging the issue and we're closing in a fix
        to the gap in the W/A implementation:
    Driver Changes:

      Wa_16019325821 (Gen12.70), Wa_14019159160 (MTL), Wa_16015675438,
