This is possibly temporary. I can trigger an unending IRQ storm on G8x
in some circumstances, and have no idea how to handle that particular PFIFO
exception correctly yet.
I swore I'd actually do this properly and not go the horrible route
we did with nv4x, but I won't get around to it just yet with so many
*actually* interesting things to do first.. One day.
Since someone already added nv86, why not!
Enum can be of pretty much any size since C leaves the choice of size up to the implementation. So avoid using it in new interfaces like the vblank pre- & post-modeset ioctl. Thanks to hch for spotting this.
On my 865G machine, it seems the CPU will receive interrupt before
irq_postinstall is called. This will cause kernel oops because vblank is not
inited at that time. Clear interrupt status before install seems fixing this
problem.

This tries to automatically fetch a git revision string and if succeeds,
it #defines GIT_REVISION string macro. Packagers can override it by
'make GIT_REVISION=foo'.
Update Nouveau to use GIT_REVISION, if defined, instead of DRIVER_DATE
in struct drm_driver.

The batchbuffer submission paths were fixed to use the 965-specific command,
but the vblank tasklet was not. When the older version is sent, the 965 will
lock up.
TV out needs to do load detection, which means we have to find an
available pipe to use for the detection. Port over the pipe reservation
code for this purpose.
Put off registering new outputs with sysfs until they're properly configured,
or we may get duplicates if the type hasn't been set yet (as is the case with
SDVO initialization). This also means moving de-registration into the cleanup
function instead of output destroy, since the latter occurs during the normal
course of setup when an output isn't found (and therefore not registered with
sysfs yet.
If the driver is 'modeset' enabled, it'll register it's interrupt
handler at load time. Set the devname in this case so that
/proc/interrupts makes sense.
This patch ties outputs, output properties and hotplug events into the
DRM core. Each output has a corresponding directory under the primary
DRM device (usually card0) containing dpms, edid, modes, and connection
status files.
New hotplug change events occur when outputs are added or hotplug events
are detected.
