When kfd need to be reset, sent command to HWS might cause hang and get unnecessary timeout. This change try not to touch HW in pre_reset and keep queues to be in the evicted state when the reset is done, so they are not put back on the runlist. These queues will be destroied on process termination. Signed-off-by:

As part of the ib padding process, accessing the RLC_SPM_* register may trigger gfx hang. Since gfxoff may be already kicked during the whole period. To address that, we manually toggle gfx on/off around the RLC_SPM_* register access. This can resolve the gfx hang issue observed on running Talos with RDP launched in parallel. Signed-off-by:

Previously there was a check based on chip # for chips that aligned to >=CHIP_NAVI10 to have RLC stopped as part of DPMS check. This was because of gfxclk being controlled by RLC in the newer designs. As part of IP version checking though, this got changed to match IP version for SMU. Because Renoir designs also include smu11 that meant that even GFX9 started to stop RLC earlier. Adjust to match GFX IP version instead of SMU IP version to restore the previous behavior.

[Why]: When we call hmm_range_fault to map memory after a migration, we don't expect memory to be migrated again as a result of hmm_range_fault. The driver ensures that all memory is in GPU-accessible locations so that no migration should be needed. However, there is one corner case where hmm_range_fault can unexpectedly cause a migration from DEVICE_PRIVATE back to system memory due to a write-fault when a system memory page in the same range was mapped read-only (e.g. COW). Ranges with individual pages in different locations are usually the result of failed page migrations (e.g. page lock contention). The unexpected migration back to system memory causes a deadlock from recursive locking in our driver. [How]: Creating a task reference new member under svm_range_list struct. Setting this with "current" reference, right before the hmm_range_fault is called. This member is checked against "current" reference at svm_migrate_to_ram callback function. If equal, the migration will be ignored. Signed-off-by:

There is no reason to allow for partial buffers from userspace in our debugfs. In this particular case callers will zero out the wr_buf but if callers in the future don't do that we might be looking at corrupt data. Linus puts it better than I can in https://lkml.org/lkml/2021/10/26/993Reviewed-by:

[WHY] If timing and bpp of displays on mst hub are not changed, pbn, slot_num for displays should not be changed. Linux user mode may initiate atomic_check with different display configuration after set mode finished. This will call to amdgpu_dm to re-compute payload, slot_num of displays and saved to dm_connect_state. stream->timing.flags.dsc, pbn, slot_num are updated to values which may be different from that were used for set mode. when dsc hub with 3 4k@60hz dp connected, 3 dsc engines are enabled. timing.flags.dsc = 1. timing.flags.dsc are changed to 0 due to atomic check. when dsc hub is unplugged, amdgpu driver check timing.flags.dsc for last mode set and find out flags.dsc = 0, then does not disable dsc. [HOW] check status of displays on dsc mst hubs. re-compute pbn, slot_num, timing.flags.dsc only if there is mode, connect or enable/disable change. Acked-by:

commit 652de07a ("drm/amd/display: Fully switch to dmub for all dcn21 asics") switched over to using dmub on Renoir to fix Gitlab 1735, but this implied a new dependency on newer firmware which might not be met on older kernel versions. Since sw_init runs before hw_init, there is an opportunity to determine whether or not the firmware version is new to adjust the behavior.
