This commit adds a null check for the set_output_gamma function pointer in the dcn401_set_output_transfer_func function. Previously, set_output_gamma was being checked for null, but then it was being dereferenced without any null check. This could lead to a null pointer dereference if set_output_gamma is null. To fix this, we now ensure that set_output_gamma is not null before dereferencing it. We do this by adding a null check for set_output_gamma before the call to set_output_gamma.

This commit adds a null check for the set_output_gamma function pointer in the dcn20_set_output_transfer_func function. Previously, set_output_gamma was being checked for null at line 1030, but then it was being dereferenced without any null check at line 1048. This could potentially lead to a null pointer dereference error if set_output_gamma is null. To fix this, we now ensure that set_output_gamma is not null before dereferencing it.

Adding NOP packets one by one in the ring does not use the CP efficiently. Solution: Use CP optimization while adding NOP packet's so PFP can discard NOP packets based on information of count from the Header instead of fetching all NOP packets one by one. Reviewed-by:

Support per-queue reset for GFX9. The recommendation is for the driver to target reset the HW queue via a SPI MMIO register write. Since this requires pipe and HW queue info and MEC FW is limited to doorbell reports of hung queues after an unmap failure, scan the HW queue slots defined by SET_RESOURCES first to identify the user queue candidates to reset. Only signal reset events to processes that have had a queue reset. If queue reset fails, fall back to GPU reset. Signed-off-by:

This commit corrects the function comment for 'dpp401_dscl_program_isharp' in 'dcn401_dpp_dscl.c'. The comment previously included a description for a non-existent parameter 'bs_coeffs_updated'.

debugfs register list for dump is cleaned as it have some issues related to proper power state of the IP before register read. Since the above mentioned is removed we no longer want this to be dumped part of the devcoredump and hence removed. Reviewed-by:

There are some problem with existing amdgpu_reset_dump_register_list debugfs node. It is supposed to read a list of registers but there could be cases when the IP is not in correct power state. Register read in such cases could lead to more problems. We are taking care of all such power states in devcoredump and dumping the registers of need for debugging. So cleaning this code and we dont need this functionality via debugfs anymore. Reviewed-by:

Instead of manually passing around 'struct edid *' and its size, use 'struct drm_edid', which encapsulates a validated combination of both. As the drm_edid_ can handle NULL gracefully, the explicit checks can be dropped. Also save a few characters by transforming '&array[0]' to the equivalent 'array' and using 'max_t(int, ...)' instead of manual casts. Signed-off-by:
