[Why & How] When MPC enabled, need to adjust x and hot spot x position on one pipe when the cursor is between MPC slices i.e. when the cursor is moving from one MPC slice to next slice, while whole cursor size is not contained within one pipe, to make part of the cursor to be visible on the other pipe.

[WHAT & HOW] Integer multiplies integer may overflow in context that expects an expression of unsigned/siged long long (64 bits). This can be fixed by casting integer to unsigned/siged long long to force 64 bits results. This fixes 26 OVERFLOW_BEFORE_WIDEN issues reported by Coverity. Reviewed-by:

[Why] Certain configurations of DCN401 require ODM4:1 to support DCC for 10K surfaces. DCC should be conservatively disabled in those cases. The issue is that current logic limits 10K surface DCC for all configurations of DCN401. [How] Add DC ASIC cap to indicate max surface width that can support DCC. Disable DCC if this ASIC cap is non-zero and surface width exceeds it. Reviewed-by:

[why] Previously, we decide on the unbounded request purely based on pipe_cnt which is a wrong variable to use to determine how many pipes are in "use". DML already accounts for number of pipes in use along with other various factors and is a more reliable method of determination.

Although designs may contain an ISP IP block, the camera might be a USB camera. Because of this the ISP firmware is considered optional from amdgpu. However if the firmware doesn't get loaded the hardware should not be initialized. Adjust the return code for early init to ensure the IP block doesn't go through the other init and fini sequences. Also decrease the message about firmware load failure to debug so it's not as alarming to users. Acked-by:
