[WHY] Currently driver reduces verified link caps on DPIA devices if a link is trained at a link rate below the max rate verified during link detection. This blocks high bandwidth modes after setting a low bandwidth mode. [HOW] Only update link rate after a successful link train if link is MST. Reviewed-by:

[Why] The link enablement sequence can end up resetting the encoder while the PHY symclk isn't yet on. This means that waiting for symclk on will timeout, along with the reset bit never asserting high. This causes unnecessary delay when enabling the link and produces a warning affecting multiple IGT tests. [How] Don't wait for the symclk to be on here because firmware already does. Don't wait for reset if we know the symclk isn't on. Split the reset into a helper function that checks the bit and decides whether or not a delay is sufficient. Reviewed-by:

[Why] Recent backports from open source do not have header inclusion pattern that is consistent with inclusion style in the rest of the file. This breaks the internal tool builds as well. A recent commit erronously modified the original DML formula for calculating ActiveClockChangeLatencyHidingY. This resulted in a FCLK deviation from the golden values. [How] Change the way in which display_mode_vba.h is included so that it is consistent with the inclusion style in rest of the file which also fixes the tool build. Restore the DML formula to its original state to fix the FCLK deviation. Reviewed-by:

[Description] - Need to disable phantom OTG after it's enabled in order to restore it to it's original state. - If it's enabled and then an MCLK switch comes in we may not prefetch the correct data since the phantom OTG could already be in the middle of the frame. Reviewed-by:

[Description] - For SubVP transitioning into MPO, we want to use a minimal transition to prevent transient underflow - Transitioning a phantom pipe directly into a "real" pipe can result in underflow due to the HUBP still having it's "phantom" programming when HUBP is unblanked (have to wait for next VUPDATE of the new OTG) - Also ensure subvp pipe lock is acquired early enough for programming in dc_commit_state_no_check - When disabling phantom planes, enable phantom OTG first so the disable gets the double buffer update Reviewed-by:

Cable ID is a DP2 feature to identify max certified link rate that a cable can carry. The cable identification method requires both cable and display hardware support. Since the specs comes late, it is anticipated that the first round of DP2 cables and displays may not be fully compatible to reliably return cable ID data. Therefore the decision of our cable id policy is that if the cable can return non zero cable id data, we will take cable's link rate capability into account. However if we get zero data, the cable link rate capability is considered inconclusive. In this case, we will not take cable's capability into account to avoid of over limiting hardware capability from users. The max overall link rate capability is still determined after actual dp pre-training. Cable id is considered as an auxiliary method of determining max link bandwidth capability. Reviewed-by:

Checkpoint BOs last. That way we don't need to close dmabuf FDs if something else fails later. This avoids problematic access to user mode memory in the error handling code path. criu_checkpoint_bos has its own error handling and cleanup that does not depend on access to user memory. In the private data, keep BOs before the remaining objects. This is necessary to restore things in the correct order as restoring events depends on the events-page BO being restored first. Fixes: be072b06 ("drm/amdkfd: CRIU export BOs as prime dmabuf objects") Reported-by:

This is the pull request for a whole bunch of fixes and prep-work that was done to support Ampere acceleration prior to GSP-RM being available. It uses the ACR firmware released by NVIDIA in linux-firmware, as we do on earlier GPUs. The work to support running on top of GSP-RM also heavily depends on various pieces of this series. In addition to the new HW support, general stability of the driver should be improved, especially around recovering HW from bugs that can be generated by userspace driver components. Signed-off-by:
