commit 58d7e3e427db1bd68f33025519a9468140280a75 upstream.

drm/radeon: drop register readback in cayman_cp_int_cntl_setup

2016-11-24T04:02:21+00:00

[ Upstream commit 537b4b462caa8bfb9726d9695b8e56e2d5e6b41e ] The read is taking a considerable amount of time (about 50us on this machine). The register does not ever hold anything other than the ring ID that is updated in this exact function, so there is no need for the read modify write cycle. This chops off a big chunk of the time spent in hardirq disabled context, as this function is called multiple times in the interrupt handler. With this change applied radeon won't show up in the list of the worst IRQ latency offenders anymore, where it was a regular before.
