2024-01-19drm/amdgpu: revert "Adjust removal control flow for smu v13_0_2"Christian König4-65/+1
Calling amdgpu_device_ip_resume_phase1() during shutdown leaves the HW in an active state and is an unbalanced use of the IP callbacks. Using the IP callbacks like this can lead to memory leaks, double free and imbalanced reference counters. Leaving the HW in an active state can lead to DMA accesses to memory now freed by the driver. Both is a complete no-go for driver unload so completely revert the workaround for now. This reverts commit f5c7e7797060255dbc8160734ccc5ad6183c5e04.

2024-01-15drm/xe/migrate: Fix CCS copy for small VRAM copy chunksThomas Hellström2-50/+80
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.

McKenney <paulmck@kernel.org> [ This particular warning is broken on GCC11. In future changes it will be moved to the normal C flags in the top level Makefile (out of Makefile.extrawarn), but accounting for the compiler support. Just remove it out of xe's forced extra warnings for now ] Signed-off-by: Lucas De Marchi <lucas.demarchi@intel.com> (cherry picked from commit a109d19992294736abd4f4232ea639e03eb1f9e7) Signed-off-by: Thomas Hellström <thomas.hellstrom@linux.intel.com>
