This is recommended by HW designers. Previously when it was set to 1, the PDE walk error in VM fault will be treated as PERMISSION_OR_INVALID_PAGE_FAULT rather than usually expected OTHER_FAULT. As a result, the retry control in VM_CONTEXT*_CNTL will change accordingly. The above behavior is kind of abnormal. Furthermore, the PDE_FAULT_CLASSIFICATION == 1 feature was targeted for very old ASICs and it never made it way to production. Therefore, we should set it to 0. Signed-off-by:

Only select HMM_MIRROR will get kernel config dependency warnings if CONFIG_HMM is missing in the config. Add depends on HMM will solve the issue.

Use HMM helper function hmm_vma_fault() to get physical pages backing userptr and start CPU page table update track of those pages. Then use hmm_vma_range_done() to check if those pages are updated before amdgpu_cs_submit for gfx or before user queues are resumed for kfd. If userptr pages are updated, for gfx, amdgpu_cs_ioctl will restart from scratch, for kfd, restore worker is rescheduled to retry. HMM simplify the CPU page table concurrent update check, so remove guptasklock, mmu_invalidations, last_set_pages fields from amdgpu_ttm_tt struct. HMM does not pin the page (increase page ref count), so remove related operations like release_pages(), put_page(), mark_page_dirty(). Signed-off-by:

There is circular lock between gfx and kfd path with HMM change: lock(dqm) -> bo::reserve -> amdgpu_mn_lock To avoid this, move init/unint_mqd() out of lock(dqm), to remove nested locking between mmap_sem and bo::reserve. The locking order is: bo::reserve -> amdgpu_mn_lock(p->mn) Signed-off-by:

[Why] dc_commit_updates_for_stream is called twice per stream: once with the flip data and once will all other data. This causes problems when these DC calls have different numbers of planes For example, a commit with a pageflip on plane A and a non-pageflip change on plane B will first call into DC with just plane A, causing plane B to be disabled. Then it will call into DC with both planes, re-enabling plane B [How] Merge flip and full into a single bundle Apart from the single DC call, the logic should not be changed by this patch Signed-off-by:

[Why] eDP v1.4 allows panels to report link rates other than RBR/HBR/HBR2, that may be more optimal for the panel's timing. Power can be saved by using a link rate closer to the required bandwidth of the panel's timing.

[Why] The wait_for_vblank boolean in commit_tail was passed by reference into each stream commit, and if that commit was an asynchronous flip, it would disable vblank waits on all subsequent flips. This made the behaviour depend on crtc order in a non-intuitive way, although since the asynchronous pageflip flag is only used by the legacy IOCTLs at the moment it is never an issue [How] Find wait_for_vblank before doing any stream commits Signed-off-by:
