drm/xe/mocs: Clarify difference between hw and sw sizes

2024-06-28T21:00:09+00:00

It's not very obvious what the difference is between the 'size' and 'n_entries' fields of the MOCS structure. Rename both fields slightly and add some comments explaining that one is the documentation-defined table size, while the other is the number of entries that can be programmed into the hardware (and the documented table size can potentially be smaller than the number of hardware entries).

drm/xe/rtp: Allow to OR rules

2024-06-18T19:03:28+00:00

Some workarounds started to depend on different set of conditions where the action should be applied if any of them match. See e.g. commit 24d0d98af1c3 ("drm/xe/xe2lpm: Fixup Wa_14020756599"). Add XE_RTP_MATCH_OR that allows to implement a logical OR for the rules. Normal precedence applies: r1, r2, OR, r3 means (r1 AND r2) OR r3 The check is shortcut as soon as a set of conditions match. v2: Do not match on empty number of rules-other-than-OR evaluated Reviewed-by: Matt Roper Signed-off-by: Lucas De Marchi Signed-off-by: Matt Roper Link: https://patchwork.freedesktop.org/patch/msgid/20240618050044.324454-4-lucas.demarchi@intel.com

drm/xe/rtp: Allow to match 0 sr entries

2024-06-18T19:03:27+00:00

If none of the rules match, there should be 0 entries in the sr xarray, so none of them should have a register matching.

drm/xe/tests: Use uninterruptible VM lock

2024-05-21T20:18:51+00:00

Interruptible lock can return error and needed a return value check. This test should finish quick enough so use a uninterruptible lock instead.

drm/xe: Delete PT update selftest

2024-04-26T19:10:09+00:00

IGTs (e.g. xe_vm) can provide the exact same coverage as the PT update selftest. The PT update selftest is dependent on internal functions which can change thus maintaining this test is costly and provide no extra coverage. Delete this test.
