This patch includes the remaining improvements to the SDMA reset logic: - Added `gfx_guilty` and `page_guilty` flags to track guilty queues. - Updated the reset and resume functions to handle the guilty state. - Cached the `rptr` before reset. v2: 1.replace the caller with a guilty bool. If the queue is the guilty one, set the rptr and wptr to the saved wptr value, else, set the rptr and wptr to the saved rptr value. (Alex) 2. cache the rptr before the reset. (Alex) v3: Keeping intermediate variables like u64 rwptr simplifies resotre rptr/wptr.(Lijo) Suggested-by:
