These operations can take quite some time, and we really don't want to
have to hold a spinlock for too long.
Now that the lock ordering for vm and the gr/nv84 hw bug workaround has
been reversed, it's possible to use a mutex here.

These are pretty much useless for reclocking purposes. Lets make it
clearer what they're for and move them to DEVINIT to signify they're

There might be issue with lockup detection when scheduling on an

UVD ring can't use scratch thus it does need writeback buffer to keep
a valid address or radeon_ring_backup will trigger a kernel fault.
It's ok to not unpin the write back buffer on suspend as it leave in
gtt and thus does not need eviction.
v2: Fix the uvd case.

If a buffer is never bound to a virtual memory pagetable than don't try
to unbind it. Only drawback is that we don't update the pagetable when
unbinding the ib pool buffer which is fine because it only happens at
suspend or module unload/shutdown.
Fixes spurious messages about buffers without VM mappings. E.g.:
radeon 0000:01:00.0: bo ffff88020afac400 don't has a mapping in vm ffff88021ca2b900

drm/i915/sdvo: Use &intel_sdvo->ddc instead of intel_sdvo->i2c for DDC
Egbert Eich fixed a long-standing bug where we simply used a
non-working i2c controller to read the EDID for SDVO-LVDS panels.
Unfortunately some machines seem to not be able to cope with the mode
provided in the EDID. Specifically they seem to not be able to cope
with a 4x pixel mutliplier instead of a 2x one, which seems to have
been worked around by slightly changing the panels native mode in the
VBT so that the dotclock is just barely above 50MHz.
Since it took forever to notice the breakage it's fairly safe to
assume that at least for SDVO-LVDS panels the VBT contains fairly sane
data. So just switch around the order and use VBT modes first.
v2: Also add EDID modes just in case, and spell Egbert correctly.
v3: Elaborate a bit more about what's going on on Chris' machine.

sdvo->hotplug_active is initialised during intel_sdvo_setup_outputs(),
and so we never enabled the hotplug interrupts on SDVO as we were
checking too early.

the storm detection and handling starting with

DRM/I915: Add enum hpd_pin to intel_encoder.
and the follow-up patches to use the new encoder->hpd_pin variable for
the different irq setup functions.
The problem is that encoder->hpd_pin was set up _before_ the output
setup was done and so before we could assess the hotplug capabilities
of the outputs on an sdvo encoder.

Fixing this will make the pin/unpin count match and prevent cursor
