drm/xe/tests: add live KUnit coverage for BO page-size allocation modes

2026-07-30T03:19:34Z

Add live KUnit coverage for the debug-controlled BO page-size allocation modes. The new tests cover forced 2M mode, forced 1G mode, and mixed mode. They verify that user BO creation applies the expected NEEDS_* flags, that no unexpected page-size flags are added in the forced modes, that BO size is rounded as expected, and that page_alignment matches the selected leaf size. The mixed-mode test does not assume a strict per-allocation rotation sequence, since the device-global mixed-mode index may be perturbed by concurrent BO creation on a live system. Instead, it validates that each allocation results in one valid mixed-mode page-size outcome. Treat transient VRAM allocation failures as skipped test cases so the tests can run in varying live environments without producing false failures. v3 - address review comments - rework mixed-mode test to avoid assuming strict rotation order - reword commit message v4 - skip VRAM-targeted live tests on non-dGFX devices v5 - advance the mixed-mode index in the test v6 - Gaurd kunit tests under CONFIG_DRM_XE_DEBUG_PAGE_SIZE v9 - consider XE_VRAM_FLAGS_NEED64K in mixed mode for certain platoform min alignment expectations.

drm/xe/tests: Add migration packet test

2026-07-11T14:15:34Z

One of our migration data packet (descriptor) is based on the KLV encoding. Add a simple descriptor initialization test, as we plan to use new KLV helper functions there.

drm/xe: Add tile_count to xe_probed_info

2026-07-02T21:41:56Z

On multi-tile platforms, we need to probe the hardware for the number of tiles that are present in the platform. That means that we should do that as part of xe_probe_info() instead of xe_info_init(). Do that.

drm/xe: Don't initialize tile_count in xe_info_init_early()

2026-07-02T21:41:55Z

The value of xe->info.tile_count is only really valid after xe_info_probe_tile_count(). Any use of tile_count before that point is invalid and, consequently, initializing it in xe_info_init_early() is pointless. Move the initialization to xe_info_probe_tile_count().

drm/xe: Add graphics/media IPs and their step info to xe_probed_info

2026-07-02T21:41:54Z

On GMDID-based platforms, the driver needs to probe the hardware by reading GMDID registers in order to identify the graphics/media/display IPs that are present in the platform as well as their stepping values. Currently, xe_info_init() has such a probing logic, but that task should be rather responsibility of xe_probe_info(). As such, move it to the latter. For pre-GMDID platforms, the IPs are identified via PCI devid and revid fields, which is arguably also hardware dependent. So do the same for those platforms.
