Currently, there are issues with enabling PSR-SU + DSC. This stems from the fact that DSC imposes a slice height on transmitted video data and we are not conforming to that slice height in PSR-SU regions. So, pass slice_height into su_y_granularity to feed the DSC slice height into PSR-SU code. Acked-by:

All microcode runs a basic validation after it's been loaded. Each IP block as part of init will run both. Introduce a wrapper for request_firmware and amdgpu_ucode_validate. This wrapper will also remap any error codes from request_firmware to -ENODEV. This is so that early_init will fail if firmware couldn't be loaded instead of the IP block being disabled. Reviewed-by:

Removing the firmware framebuffer from the driver means that even if the driver doesn't support the IP blocks in a GPU it will no longer be functional after the driver fails to initialize. This change will ensure that unsupported IP blocks at least cause the driver to work with the EFI framebuffer. Cc: stable@vger.kernel.org Suggested-by:

amdgpu_ras_block_late_init will be invoked in IP specific ras_late_init call as a common helper for all the IP blocks. However, when amdgpu_ras_block_late_init call amdgpu_ras_query_error_count to query ras error counters, amdgpu_ras_query_error_count queries all the IP blocks that support ras query interface. This results to wrong error counters cached in software copies when there are ras errors detected at time zero or warm reset procedure. i.e., in sdma_ras_late_init phase, it counts on sdma/mmhub errors, while, in mmhub_ras_late_init phase, it still counts on sdma/mmhub errors. The change updates amdgpu_ras_query_error_count interface to allow query specific ip error counter. It introduces a new input parameter: query_info. if query_info is NULL, it means query all the IP blocks, otherwise, only query the ip block specified by query_info. Signed-off-by:

HPD signals on DVI ports can be fired off before the pins required for DDC probing actually make contact, due to the pins for HPD making contact first. This results in a HPD signal being asserted but DDC probing failing, resulting in hotplugging occasionally failing. Rescheduling the hotplug work for a second when we run into an HPD signal with a failing DDC probe usually gives enough time for the rest of the connector's pins to make contact, and fixes this issue.
