Hi Dave,

Ignore this request for now.  Mario ran into some problems with
further pageflipping testing so I'll send a new request once we've
sorted that out.

Hello Alex and Michel,

isn't this needed anylonger?
drm-radeon-Disable-pflip-interrupts.patch

[-]
 From 462febcc7b5f6e54648f2fd941b9f90de16e54f1 Mon Sep 17 00:00:00 2001
 From: Michel Dänzer <michel.daenzer@amd.com>
Date: Mon, 14 Jul 2014 06:42:06 +0000
Subject: drm/radeon: Disable pflip interrupts

With Mario's previous fix, there are three possible scenarios for the
pflip interrupts:

1) If a pflip interrupt can occur before the corresponding vblank
    interrupt, the sequence number of the userspace event will be too
    small by one.
2) If a pflip interrupt can occur after the vblank interrupt and after
    the next flip is programmed to the hardware, 
radeon_crtc_handle_flip()
    will complete the next flip earlier than expected by userspace.
3) Otherwise, radeon_crtc_handle_flip() doesn't perform any actual work
    when called from the pflip interrupt handler, i.e. the pflip 
interrupt
    is useless.

In summary, Mario's fix made the pflip interrupts useless in the best
case and harmful in the worst case, so let's disable them.

No it's not needed for 3.16.

[pull] radeon drm-fixes-3.16

[Alex Deucher]

Hi Dave,

Another fixes pull for radeon.  This one is a little bigger than I'd like,
but fixes a stability issue with GPUVM that led to GPU hangs that was
introduced in 3.15.  Also included is a system hang/reboot regression fix
for dpm on TN/RL hardware.
