2024-06-19drm/amdgpu: cleanup MES11 command submissionChristian König1-28/+48
The approach of having a separate WB slot for each submission doesn't really work well and for example breaks GPU reset. Use a status query packet for the fence update instead since those should always succeed we can use the fence of the original packet to signal the state of the operation. While at it cleanup the coding style.

In other words, another part of the code might be calling this function in a non-OTG master pipe context, resulting in the log message. The reason the ASSERT was triggered is that the current state wasn't updated after applying the context to the hardware. This means that the update_dsc_for_odm_change might be called from a non-OTG-MASTER. To prevent this, it's crucial to check if the current reference is pointing to an OTG master before operate in the old OTG master reference. If it's not, the function must set the old OTG reference to NULL and avoid calling resource_get_opp_heads_for_otg_master before the context is updated.

2024-06-18drm/panic: depends on !VT_CONSOLEJocelyn Falempe1-1/+1
The race condition between fbcon and drm_panic can only occurs if VT_CONSOLE is set. So update drm_panic dependency accordingly. This will make it easier for Linux distributions to enable drm_panic by disabling VT_CONSOLE, and keeping fbcon terminal. The only drawback is that fbcon won't display the boot kmsg, so it should rely on userspace to do that.
