2021-11-05drm/amd/pm: Correct DPMS disable IP version checkMario Limonciello
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.

2021-11-05drm/amdkfd: avoid recursive lock in migrations back to RAMAlex Sierra
[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: Alex Sierra <alex.sierra@amd.com> Reviewed-by: Felix Kuehling <Felix.Kuehling@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

2021-11-05drm: fb_helper: improve CONFIG_FB dependencyArnd Bergmann
My previous patch correctly addressed the possible link failure, but as Jani points out, the dependency is now stricter than it needs to be. Change it again, to allow DRM_FBDEV_EMULATION to be used when DRM_KMS_HELPER and FB are both loadable modules and DRM is linked into the kernel. As a side-effect, the option is now only visible when at least one DRM driver makes use of DRM_KMS_HELPER. This is better, because the option has no effect otherwise.
