Hi, this series fixes an issue with the IPU DC/DP/IDMAC disable sequence. The interrupt waiting code didn't work as expected, sometimes causing busy waits longer than the timeout in drm_atomic_helper_wait_for_vblanks, which would cause crashes similar to the reported "imxdrm issue on SABRE Lite" [1]. [1] http://www.spinics.net/lists/dri-devel/msg132485.html I could only reproduce the error when the overlay plane was involved, using weston with the atomic modeset patchset to trigger it, so I'm not sure if this fixes the issue above, too. regards Philipp Lucas Stach (1): gpu: ipu-v3: remove IRQ dance on DC channel disable Philipp Zabel (3): gpu: ipu-v3: add unsynchronised DP channel disabling drm/imx: call drm_atomic_helper_commit_hw_done after drm_atomic_helper_wait_for_vblanks drm/imx: add deferred plane disabling drivers/gpu/drm/imx/imx-drm-core.c | 11 +++++-- drivers/gpu/drm/imx/ipuv3-crtc.c | 22 +++++++++++++- drivers/gpu/drm/imx/ipuv3-plane.c | 24 ++++++++++----- drivers/gpu/drm/imx/ipuv3-plane.h | 5 ++++ drivers/gpu/ipu-v3/ipu-common.c | 8 +++-- drivers/gpu/ipu-v3/ipu-dc.c | 61 +++----------------------------------- drivers/gpu/ipu-v3/ipu-dp.c | 15 ++++------ drivers/gpu/ipu-v3/ipu-prv.h | 7 ++++- include/video/imx-ipu-v3.h | 2 +- 9 files changed, 74 insertions(+), 81 deletions(-) -- 2.11.0 _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
