drm/xe: Move xe_uc_fw_abi.h to abi/

2026-05-27T19:28:01+00:00

We aim to keep all pure ABI headers in the abi/ folder, but
somehow we missed this file.

drm/xe/guc: Update POLICY_SCHED_IF_IDLE documentation

2026-04-12T08:32:43+00:00

Starting from the GuC firmware version 70.12.0 the meaning of the
POLICY_SCHED_IF_IDLE has changed, which now acts as a bulk update
of the VF_CFG_SCHED_PRIORITY configurations of all VFs.

drm/xe: Enable Wa_14025515070

2026-04-03T19:56:18+00:00

Corrects a failure on context switch. On registration of context with
indirect ring state will correct state of targeted and idle command
streamers.

This Wa requires GuC 70.53+ (uapi 1.26+).  If indirect_ring_state is
enabled and Wa is unavailable, notify and disable indirect_ring_state.

Added additional XE_RTP_PASTE macros for expansion of longer rules.

drm/xe/guc: Fix kernel-doc warning in GuC scheduler ABI header

2026-02-02T17:13:31+00:00

The GuC scheduler ABI header contains a file-level comment that is not
intended to document a kernel-doc symbol. Using kernel-doc comment
syntax (/** */) triggers kernel-doc warnings.

With "-Werror", this causes the build to fail. Convert the comment to a
regular block comment.

drm/xe/pf: Add functions to set preempt timeouts for each group

2025-12-22T18:22:16+00:00

The KLV to set the preemption timeout for each groups works the exact
same way as the one for the exec quantums, so we add similar functions.

drm/xe/pf: Add functions to set exec quantums for each group

2025-12-22T18:22:14+00:00

The GuC has a new dedicated KLV to set the EQs for the groups. The GuC
always sets the EQs for all the groups (even the ones not enabled). If
we provide fewer values than the max number of groups (8), the GuC will
set the remaining ones to 0 (infinity).

Note that the new KLV can be used even when groups are disabled (as the
GuC always consider group0 to be active), so we can use it when encoding
the SRIOV config.

drm/xe/pf: Prep for multiple exec quantums and preemption timeouts

2025-12-22T18:22:12+00:00

Each scheduler group can be independently configured with its own exec
quantum and preemption timeouts. The existing KLVs to configure those
parameters will apply the value to all groups (even if they're not
enabled at the moment).

When scheduler groups are disabled, the GuC uses the values from Group 0.
