[PATCH 02/10] drm/qxl: more fence wait rework
From: Gerd Hoffmann <kraxel@redhat.com>
Date: 2021-02-16 11:39:52
Also in:
dri-devel, lkml
Subsystem:
drm driver for qxl virtual gpu, drm drivers, drm drivers and misc gpu patches, the rest · Maintainers:
Dave Airlie, Gerd Hoffmann, David Airlie, Simona Vetter, Maarten Lankhorst, Maxime Ripard, Thomas Zimmermann, Linus Torvalds
Move qxl_io_notify_oom() call into wait condition.
That way the driver will call it again if one call
wasn't enough.
Also allows to remove the extra dma_fence_is_signaled()
check and the goto.
Fixes: 5a838e5d5825 ("drm/qxl: simplify qxl_fence_wait")
