Changes in v4: - Added checks for is_suspended bits in hardirqs - Added GPU suspended bit (and handling of it) - Reordered panfrost_drv_comp_bits entries - Commit description fixes Changes in v3: - Removed useless GPU_INT_CLEAR write in suspend path - Changed to clear suspend bits in job/mmu reset path This series contains a fast fix for the basic GPU poweroff functionality and goes further by implementing interrupt masking and synchronization before suspend. For more information, please look at the conversation at [1], which explains the regression seen with the poweroff commit and the initial approaches taken to solve that. Cheers!
