drm/xe/kunit: Fix forcewake assertion in mocs test

2025-11-18T18:04:48+00:00

The MOCS kunit test calls KUNIT_ASSERT_TRUE_MSG() with a condition of 'true;' this prevents the assertion from ever failing. Replace KUNIT_ASSERT_TRUE_MSG with KUNIT_FAIL_AND_ABORT to get the intended failure behavior in cases where forcewake was not acquired successfully.

drm/xe/pf: Use migration-friendly GGTT auto-provisioning

2025-11-13T13:32:34+00:00

Instead of trying very hard to find the largest fair GGTT size that could be allocated for VFs on the current tile, pick some smaller rounded down to power-of-two value that is more likely to be provisioned in the same manner by the other PF instance: num VFs | GGTT space (MiB) --------+----------------- 63..57 | 56 56..29 | 64 28..15 | 128 14..8 | 256 7..4 | 512 3..2 | 1024 1 | 2048 (regular PF) 1 | 3584 (admin only PF) Note that due to FW/HW limitations we can't share all 4GiB GGTT address space with VFs, so for the larger (>7) number of the VFs the change in the outcome is happening at different points than we have in case of GuC contexts/doorbells IDs.

drm/xe/tests/pci: Convert GT count check to general device check

2025-10-22T12:49:16+00:00

We already have check_graphics_ip() and check_media_ip() as general functions to check the IP descriptors. The check in check_platform_gt_count() is simple enough such that we can convert the function to a more general device check. In an upcoming change, we will also add some checks for other members of struct xe_device_desc. As such, rename check_platform_gt_count() to check_platform_desc(). While at it, use inline (unsigned int) casting of max_gt_per_tile to keep checks for each member localized; and use KUNIT_EXPECT_*() variants of the macros to allow multiple issues to be reported.

drm/xe: Read VF GMD_ID with a specifically-allocated dummy GT

2025-10-14T14:44:57+00:00

SRIOV VF initialization has a bit of a chicken and egg design problem. Determining the IP version of the graphics and media IPs can't be done via direct register reads as it is on PF or native and instead requires querying the GuC. However initialization of the GT, including its GuC, needs to wait until after we know the IP versions so that the proper initialization steps for the platform/IP are followed. Currently the (somewhat hacky) solution is to manually fill out just enough fields in tile 0's primary GT structure to make it look as if the GT has been initialized so that the GuC can be partially initialized and queried to obtain the GMD_ID values. When the GT gets properly initialized during the regular flows, the hacked-up values will get overwritten as part of the general initialization flows. Rather than using tile 0's primary GT structure to hold the hacked up values for querying every GT on every tile, instead allocate a dedicated dummy structure. This will allow us to move the tile->primary_gt's allocation to a more consistent place later in the initialization flow in future patches (i.e., we shouldn't even allocate this GT structure if the GT is disabled/unavailable). It also helps ensure there can't be any accidental leakage of initialization or state between the dummy initialization for GMD_ID and the real driver initialization of the GT. v2: - Initialize gt->tile for temporary GT. (CI, Michal) - Use scope-based cleanup handler to free temp GT. (Michal) - Propagate actual error code from xe_gt_sriov_vf_bootstrap() rather than just setting IP version to 0.0 now that read_gmdid() can return an error. (Michal) v3: - Explicitly initialize gt to NULL, just in case something else gets inserted before the kzalloc() in the future.
