v1 reference: https://patchwork.kernel.org/project/dri-devel/cover/20240117031212.1104034-1-nunes.erico@xxxxxxxxx/ Changes v1 -> v2: - Dropped patch 1 which aimed to fix https://gitlab.freedesktop.org/mesa/mesa/-/issues/8415 . That will require more testing and an actual fix to the irq/timeout handler race. It can be solved separately so I am deferring it to a followup patch and keeping that issue open. - Added patches 2 and 4 to cover "reset time out" and bus stop bit to hard reset in gp as well. - Added handling of all processors in synchronize_irq in patch 5 to cover multiple pp. Dropped unnecessary duplicate fence in patch 5. - Added patch 7 in v2. After some discussion in patch 4 (v1), it seems to be reasonable to bump our timeout value so that we further decrease the chance of users actually hitting any of these timeouts by default. - Reworked patch 8 in v2. Since I broadened the work to not only focus in pp anymore, I also included the change to the other blocks as well. - Collected some reviews and acks in unmodified patches.
