cffd77865f drm/xe/oa: Enable Xe2+ overrun mode 
Enable Xe2+ overrun mode. For Xe2+, when overrun mode is enabled, there are
no partial reports at the end of buffer, making the OA buffer effectively a
non-power-of-2 size circular buffer whose size, circ_size, is a multiple of
the report size.

v2: Fix implementation of xe_oa_circ_diff/xe_oa_circ_incr (Umesh)

3a1fc394ba drm/xe/oa: Changes to OA_TAKEN 
Rename OA_TAKEN to xe_oa_circ_diff, since xe_oa_circ_diff better describes
what the macro actually does. Also convert to function and add xe_oa_stream
arg. These will be used in the following patch.

52c2e956dc drm/xe/perf/uapi: "Perf" layer to support multiple perf counter stream types 
In Xe, the plan is to support multiple types of perf counter streams (OA is
only one type of these streams). Rather than introduce NxM ioctls for
these (N perf streams with M ioctl's per perf stream), we decide to
multiplex these (N different stream types and the M ops for each of these
stream types) through a single PERF ioctl. This multiplexing is the purpose
of the PERF layer.

In addition to PERF DRM ioctl's, another set of ioctl's on the PERF fd are
defined. These are expected to be common to different PERF stream types and
therefore defined at the PERF layer itself.

v2: Add param_size to 'struct drm_xe_perf_param' (Umesh)

support for OR condition that change can be removed. RTP now also

xe_rtp_match_when_media2000() used in that commit.

97fedf015c drm/xe: Use fixed CCS mode when running in SR-IOV mode 
We don't support changing CCS mode when running in SR-IOV mode yet.
When running as a PF driver just apply default ccs_mode=1 that VF
drivers will assume as already applied and fixed.

7ddb9403dd drm/xe: Sample ctx timestamp to determine if jobs have timed out 
In GuC TDR sample ctx timestamp to determine if jobs have timed out. The
scheduling enable needs to be toggled to properly sample the timestamp.
If a job has not been running for longer than the timeout period,
re-enable scheduling and restart the TDR.

v2:
 - Use GT clock to msec helper (Umesh, off list)
 - s/ctx_timestamp_job/ctx_job_timestamp
v3:
 - Fix state machine for TDR, mainly decouple sched disable and
   deregister (testing)
 - Rebase (CI)
v4:
 - Fix checkpatch && newline issue (CI)
 - Do not deregister on wedged or unregistered (CI)
 - Fix refcounting bugs (CI)
 - Move devcoredump above VM / kernel job check (John H)
 - Add comment for check_timeout state usage (John H)
 - Assert pending disable not inflight when enabling scheduling (John H)
 - Use enable_scheduling in other scheduling enable code (John H)
 - Add comments on a few steps in TDR (John H)
 - Add assert for timestamp overflow protection (John H)
v6:
 - Use mul_u64_u32_div (CI, checkpath)
 - Change check time to dbg level (Paulo)
 - Add immediate mode to sched disable (inspection)
 - Use xe_gt_* messages (John H)
 - Fix typo in comment (John H)
 - Check timeout before clearing pending disable (Paulo)
v7:
 - Fix ADJUST_FIVE_PERCENT macro (checkpatch)
 - Don't print sched disable failure message on GT reset (John H)
 - Move kernel / VM jobs WARNs near comment (John H)
