drm/amd/display: Avoid overflow from uint32_t to uint8_t

2024-09-08T05:56:39Z

[ Upstream commit d6b54900c564e35989cf6813e4071504fa0a90e0 ] [WHAT & HOW] dmub_rb_cmd's ramping_boundary has size of uint8_t and it is assigned 0xFFFF. Fix it by changing it to uint8_t with value of 0xFF. This fixes 2 INTEGER_OVERFLOW issues reported by Coverity.

drm/amd/display: Don't use fsleep for PSR exit waits on dmub replay

2024-09-08T05:56:38Z

[ Upstream commit b5236da757adc75d7e52c69bdc233d29249a0d0c ] [Why] These functions can be called from high IRQ levels and the OS will hang if it tries to use a usleep_highres or a msleep. [How] Replace the flseep with a udelay for dmub_replay_enable.

drm/amd/display: Replace dm_execute_dmub_cmd with dc_wake_and_execute_dmub_cmd

2024-08-14T13:34:23Z

[ Upstream commit f2aaed194a54d78c307c44d1829c7e1ba67e9ba5 ] In the commit c2cec7a872b6 ("drm/amd/display: Wake DMCUB before sending a command for replay feature"), replaced dm_execute_dmub_cmd with dc_wake_and_execute_dmub_cmd in multiple areas, but due to merge issues the replacement of this function in the dmub_replay_copy_settings was missed. This commit replaces the old dm_execute_dmub_cmd with dc_wake_and_execute_dmub_cmd.

drm/amd/display: Wake DMCUB before sending a command for replay feature

2024-08-14T13:34:14Z

[ Upstream commit 3601a35a2e9d640233f4bc3496f7603b93f9c143 ] [Why] We can hang in place trying to send commands when the DMCUB isn't powered on. [How] For functions that execute within a DC context or DC lock we can wrap the direct calls to dm_execute_dmub_cmd/list with code that exits idle power optimizations and reallows once we're done with the command submission on success. For DM direct submissions the DM will need to manage the enter/exit sequencing manually. We cannot invoke a DMCUB command directly within the DM execution helper or we can deadlock.
