drm/radeon/kms: catch atombios infinite loop and break out of it
In somecase the atombios code might lead to infinite loop because the GPU is in broken state, this patch track the jump history and will abort atombios execution if we are stuck executing the same jump for more than 1sec. Note that otherwise in some case we might enter an infinite loop in the kernel context which is bad. Signed-off-by: Jerome Glisse <jglisse@redhat.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
