[Why] In certain cases we do link training when we don't have a backend. [How] In dc_link_set_preferred_link_settings(), store preferred link settings first and then verify that the link is DP and the link stream's backend is enabled. If either is false, then we will not do any link retraining. Signed-off-by:

[Why] Currently we are missing a few checks to see if HDR10 is allowed. In particular we never check for the extended colorimetry bit (whether its present or set to 1). Further we don't read in the dpcd block in DC that would provide these bits. [How] - Added in DC code to read in the block containing the extended colorimetry bit. Signed-off-by:

[Why] Somewhere in the atomic check reshuffle ABM got lost. ABM is a crtc property (copied from a connector property). It can change without a modeset, just like underscan. [How] In the skip_modeset branch of atomic check crtc updates, copy over the abm property. Signed-off-by:

we were only checking the return value in one place, thus changing generic_reg_wait from int to void and reading the register instead of getting it from generic_reg_wait, when we need the return value. Signed-off-by:

[Why] The plane_reset callback is subclassed but hasn't been updated since the drm helper got updated to include resetting alpha related state (state->alpha and state->pixel_blend_mode). The overlay planes exposed by amdgpu_dm were therefore being rendered as invisible by default ever since supported was exposed for alpha blending properties on overlays. This caused regressions in igt@kms_plane_multiple@atomic-tiling-none and igt@kms_plane@plane-position-covered-pipe tests. [How] Reset the plane state values to their correct values as defined in the drm helper. This fixes the IGT test regression. Signed-off-by:

[Why] Incorrect hardcoded assumptions are made regarding luma and chroma alignment. The actual values set for the DRM framebuffer should be used when programming the address. [How] Respect the given pitch for both luma and chroma planes - it's not like we can force the alignment to anything else at this point anyway. Use the FB offset for the chroma planes directly. DRM already provides this to us so there's no need to calculate it manually. While we don't actually use the chroma surface size parameters on Raven, these should have technically been fb->width / 2 and fb->height / 2 since the chroma plane is half size of the luma plane for NV12. Leave a TODO indicating that those should be set based on the actual surface format instead since this is only correct for YUV420 formats. Signed-off-by:

userptr may cross two VMAs if the forked child process (not call exec after fork) malloc buffer, then free it, and then malloc larger size buf, kerenl will create new VMA adjacent to old VMA which was cloned from parent process, some pages of userptr are in the first VMA, the rest pages are in the second VMA. HMM expects range only have one VMA, loop over all VMAs in the address range, create multiple ranges to handle this case. See is_mergeable_anon_vma in mm/mmap.c for details. Signed-off-by:

Userptr restore may have concurrent userptr invalidation after hmm_vma_fault adds the range to the hmm->ranges list, needs call hmm_vma_range_done to remove the range from hmm->ranges list first, then reschedule the restore worker. Otherwise hmm_vma_fault will add same range to the list, this will cause loop in the list because range->next point to range itself. Add function untrack_invalid_user_pages to reduce code duplication. Signed-off-by:

-
Christian König authored
Further testing showed that the idea with the chash doesn't work as expected. Especially we can't predict when we can remove the entries from the hash again. So replace the chash with a ring buffer/hash mix where entries in the container age automatically based on their timestamp. v2: use ring buffer / hash mix v3: check the timeout to make sure all entries age Signed-off-by:

The buffers should be cleared when possible but we also don't want buffer creation to fail in the rare case where the ring isn't ready during the call. This could happen during some suspend/resume sequences. Cc: Christian König <ckoenig.leichtzumerken@gmail.com> Signed-off-by:

The dumb_create API isn't intended for high performance rendering and it's more useful for userspace (ie. IGT) to have them precleared. The bonus here is that we also won't needlessly leak whatever was previously in VRAM, but it also probably wasn't sensitive if it was going through this API. Signed-off-by:

add ras post init function. Do some initialization after all IP have finished their late init. Add new member flags which will control the ras work flow. For now, vbios enable ras for us on boot. That might change in the future. So there should be a flag from vbios to tell us if ras is enabled or not on boot. Looks like there is no such info now. Other bits of the flags are reserved to control other parts of ras. Signed-off-by:
