When building with Clang: drivers/gpu/drm/amd/amdgpu/amdgpu_device.c:4160:53: warning: overflow in expression; result is -294967296 with type 'long' [-Winteger-overflow] expires = ktime_get_mono_fast_ns() + NSEC_PER_SEC * 4L; ^ 1 warning generated. Multiplication happens first due to order of operations and both NSEC_PER_SEC and 4 are long literals so the expression overflows. To avoid this, make 4 an unsigned long long literal, which matches the type of expires (u64).

[Why] Make a separation of what belongs in the differen dmub headers dmub_srv.h is for exposing dmub srv interface to rest of driver. other headers inside dmub/inc exposes cmds and definitions that are owned by the firmware [How] keep firmware owned definitions in dmub/inc move stuff that is purely driver interface headers to dmub/ since those are interface calls that are defined for rest of driver to use Signed-off-by:

[why] During hotplug, a DP port may be connected to the sink through passive adapter which does not support DPCD reads. Issuing reads without checking for this condition will result in errors [how] Ensure the link is in aux_mode before initiating operation that result in a DPCD read. Signed-off-by:

[Why] Want to make use of detile buffer of all 4 pipes to maximize amount of data stored to hide certain memory latency cases. [How] In case of 1 plane and 1 stream, program 4 pipes to each retrieve 1/4 of plane later mixed together by the MPCs. Added support for transition from 4 to 1 MPC to 2 to 1 MPC or no pipe split case and vice versa. Currently, only enabled if debug flag is set. Signed-off-by:

[Why] For a type like PSR version, it makes sense for most of the code to include a dc type, instead of having this a fw type define since this is a capability and type exposed by dc. Especially if it doesn't even need to communicate with the fw. The code that is packing the firmware command message should be the one who needs to translate the psr version into a command that the firmware understands. [How] Add a dc_psr_version enum.

On 64K LDS system, if compute work group allocate more than 32K LDS, then it can't be dispatched to CU0 and CU1 because of the reservation.
