drm/radeon/kms: enable UVD as needed (v9)
When using UVD, the driver must switch to a special UVD power
state. In the CS ioctl, switch to the power state and schedule
work to change the power state back, when the work comes up,
check if uvd is still busy and if not, switch back to the user
state, otherwise, reschedule the work.
Note: We really need some better way to decide when to
switch out of the uvd power state. Switching power states
while playback is active make uvd angry.

New asics support non-privileged IBs. This allows us
to skip IB checking in the driver since the hardware

an interrupt. The CP needs to be reset to continue. For now
just do a full GPU reset when this happens.

drm/radeon: fix AVI infoframe generation
- remove adding 2 to checksum, this is incorrect.
This was incorrectly introduced in: 92db7f6c860b8190571a9dc1fcbc16d003422fe8
http://lists.freedesktop.org/archives/dri-devel/2011-December/017717.html
However, the off by 2 was due to adding the version twice.
From the examples in the URL above:
However, the payload sum is not 0x1f8, it's 0x1f6.
00 + A8 + 5E + 00 +
00 + 28 + 00 + 10 +
00 + 48 + 00 + 28 +
00 + 48 =
0x1f6
Bits 25:24 of HDMI_VIDEOINFOFRAME_3 are the packet version, not part
of the payload. So the total would be:
(0x82 + 0x2 + 0xD) + 0x1f6 = 0x287
-0x287 = 0x79
- properly emit the AVI infoframe version. This was not being
emitted previous which is probably what caused the issue above.
This should fix blank screen when HDMI audio is enabled on
certain monitors.

Commit 10a7a0771399a57a297fca9615450dbb3f88081a ("xen: tmem: enable Xen
tmem shim to be built/loaded as a module") allows the tmem module
to be loaded any time. For this work the frontswap API had to
be able to asynchronously to call tmem_frontswap_init before
or after the swap image had been set. That was added in git
commit 905cd0e1bf9ffe82d6906a01fd974ea0f70be97a
("mm: frontswap: lazy initialization to allow tmem backends to build/run as modules").
Which means we could do this (The common case):
modprobe tmem [so calls frontswap_register_ops, no ->init]
modifies tmem_frontswap_poolid = -1
swapon /dev/xvda1 [__frontswap_init, calls -> init, tmem_frontswap_poolid is
< 0 so tmem hypercall done]
Or the failing one:
swapon /dev/xvda1 [calls __frontswap_init, sets the need_init bitmap]
modprobe tmem [calls frontswap_register_ops, -->init calls, finds out
tmem_frontswap_poolid is 0, does not make a hypercall.
Later in the module_init, sets tmem_frontswap_poolid=-1]
Which meant that in the failing case we would not call the hypercall
to initialize the pool and never be able to make any frontswap
backend calls.
Moving the frontswap_register_ops after setting the tmem_frontswap_poolid
fixes it.
