We want to wait dma fences in dirtyfb ioctl. As we don't want to make dirtyfb ioctl as blocking call we need to use dma_fence_add_callback. Callback used for dma_fence_add_callback is called from atomic context. Due to this we need to add a new frontbuffer tracking interface to queue flush. v3: - Check schedule work success rather than work being pending - Init flush work when frontbuffer struct is initialized v2: Check if flush work is already pending Signed-off-by: Jouni Högander <jouni.hogander@intel.com> Reviewed-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20230901093500.3463046-4-jouni.hogander@intel.com |
