Also add some pflip debug prints. This change allows us to wait on pflip status until the new surface address is actually submitted to the register. This reverts ed3020e923240829dcdfd3343f6e91dc02c63775 drm/amdgpu: Move MMIO flip out of spinlocked region The original change assumed DAL will aquire locks inside DAL implemetion of page_flip callback which eventaully didn't happen. This moves the flip before status update which makes sense for the non-DAL code pathes as well. Signed-off-by:

When this flag is set, we program the hardware to execute the flip during horizontal blank (i.e. for the next scanline) instead of during vertical blank (i.e. for the next frame). Currently this is only supported on ASICs which have a page flip completion interrupt (>= R600), and only if the use_pflipirq parameter has value 2 (the default). Reviewed-by:

this is to fix fatal page fault error that occured if: job is signaled/released after its timeout work is already put to the global queue (in this case the cancel_delayed_work will return false), which will lead to NX-protection error page fault during job_timeout_func. Signed-off-by:
