drm/radeon/kms: fix regression rendering issue on R6XX/R7XX
It seems that some R6XX/R7XX silently ignore HDP flush when programmed through ring, this patch addback an ioctl callback to allow R6XX/R7XX hw to perform such flush through MMIO in order to fix a regression. For more details see: http://bugzilla.kernel.org/show_bug.cgi?id=15186 Signed-off-by: Jerome Glisse <jglisse@redhat.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
