Hi Joonyoung, 2015-06-12 Joonyoung Shim <jy0922.shim@xxxxxxxxxxx>: > When the fimd is disabled by fimd_disable(), enabled overlay layers also > are disabled. If clocks for fimd are enabled by fimd_enable() on this > case, it can lead IOMMU page fault. The reason is that VIDCON0_ENVID and > VIDCON0_ENVID_F bits of VIDCON0 register are set still even though fimd > is disabled, so it may continue display output of prior when clocks for > fimd are enabled again. > > Signed-off-by: Joonyoung Shim <jy0922.shim@xxxxxxxxxxx> > --- > drivers/gpu/drm/exynos/exynos_drm_fimd.c | 2 ++ > 1 file changed, 2 insertions(+) Reviewed-by: Gustavo Padovan <gustavo.padovan@xxxxxxxxxxxxxxx> Gustavo _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
