2024-07-12drm/xe/kunit: Simplify xe_migrate live tests code layoutMichal Wajdeczko
The test case logic is implemented by the functions compiled as part of the core Xe driver module and then exported to build and register the test suite in the live test module. But we don't need to export individual test case functions, we may just export the entire test suite. And we don't need to register this test suite in a separate file, it can be done in the main file of the live test module.

2024-06-28drm/xe/mocs: Clarify difference between hw and sw sizesMatt Roper
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).

Add XE_RTP_MATCH_OR that allows to implement a logical OR for the rules.

2024-04-02drm/xe: Normalize bo flags macrosLucas De Marchi
The flags stored in the BO grew over time without following much a naming pattern. First of all, get rid of the _BIT suffix that was banned from everywhere else due to the guideline in drivers/gpu/drm/i915/i915_reg.h that xe kind of follows: Define bits using ``REG_BIT(N)``. Do **not** add ``_BIT`` suffix to the name. Here the flags aren't for a register, but it's good practice to keep it consistent. Second divergence on names is the use or not of "CREATE". This is because most of the flags are passed to xe_bo_create*() family of functions, changing its behavior. However, since the flags are also stored in the bo itself and checked elsewhere in the code, it seems better to just omit the CREATE part. With those 2 guidelines, all the flags are given the form XE_BO_FLAG_<FLAG_NAME> with the following commands: git grep -le "XE_BO_" -- drivers/gpu/drm/xe | xargs sed -i \ -e "s/XE_BO_\([_A-Z0-9]*\)_BIT/XE_BO_\1/g" \ -e 's/XE_BO_CREATE_/XE_BO_FLAG_/g' git grep -le "XE_BO_" -- drivers/gpu/drm/xe | xargs sed -i -r \ -e 's/XE_BO_(DEFER_BACKING|SCANOUT|FIXED_PLACEMENT|PAGETABLE|NEEDS_CPU_ACCESS|NEEDS_UC|INTERNAL_TEST|INTERNAL_64K|GGTT_INVALIDATE)/XE_BO_FLAG_\1/g' And then the defines in drivers/gpu/drm/xe/xe_bo.h are adjusted to follow the coding style.

Although MOCS registers became multicast in graphics version 12.50 on the primary GT, this transition did not happen until version 20 on the media GT. Considering each GT independently is mostly important for MTL/ARL where the Xe_LPM+ IP has non-MCR MOCS registers, even though Xe_LPG IP has MCR registers.

2024-02-27drm/xe/tests: Fix printf format specifiers in xe_migrate testDavid Gow
KUNIT_FAIL() is used to fail the xe_migrate test when an error occurs. However, there's a mismatch in the format specifier: '%li' is used to log 'err', which is an 'int'. Use '%i' instead of '%li', and for the case where we're printing an error pointer, just use '%pe', instead of extracting the error code manually with PTR_ERR(). (This also results in a nicer output when the error code is known.)

2024-02-26drm/xe: Convert kunit tests from mem_access to xe_pm_runtimeRodrigo Vivi
Let's convert the kunit tests that are currently relying on xe_device_mem_access_{get,put} towards the direct xe_pm_runtime_{get,put}. While doing this we need to move the get/put calls towards the outer bounds of the tests to ensure consistency with the other usages of pm_runtime on the regular paths. v2: include xe_pm.h in tests/xe_mocs.c and sort the include block while at it.

2024-01-16drm/xe: Group normal kunit tests in a single moduleLucas De Marchi
Creating one module for each compilation unit to be tested seems excessive as the number of tests increase. Group them all in a single kunit test module called xe_test.ko. The tests requiring the physical device, aka "live" tests, are still kept in separate modules since they are normally triggered via igt, and not via kunit.py. After igt is converted, those can be merged in a single module as well.

2024-01-15drm/xe/migrate: Fix CCS copy for small VRAM copy chunksThomas Hellström
Since the migrate code is using the identity map for addressing VRAM, copy chunks may become as small as 64K if the VRAM resource is fragmented. However, a chunk size smaller that 1MiB may lead to the *next* chunk's offset into the CCS metadata backup memory may not be page-aligned, and the XY_CTRL_SURF_COPY_BLT command can't handle that, and even if it could, the current code doesn't handle the offset calculaton correctly. To fix this, make sure we align the size of VRAM copy chunks to 1MiB. If the remaining data to copy is smaller than that, that's not a problem, so use the remaining size. If the VRAM copy cunk becomes fragmented due to the size alignment restriction, don't use the identity map, but instead emit PTEs into the page-table like we do for system memory. v2: - Rebase v3: - Future proof somewhat by taking into account the real data size to flat CCS metadata size ratio. (Matt Roper) - Invert a couple of if-statements for better readability. - Fix support for 4K-granularity VRAM sizes. (Tested on DG1). v4: - Fix up code comments - Fix debug printout format typo. v5: - Add a Fixes: tag.
