drm/nouveau: workaround semaphore hw bug causing unnecessary interrupts The HW will only accept the DMA_FROM_MEMORY class for DMA_SEMAPHORE without asking the driver to intervene. It appears that semaphores will work correctly even without DMA_IN_MEMORY, so lets avoid the large amount of interrupts generated by x-chan sync. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
