double-negatives and confusion when trying to interpret the parameter,
so use @force instead. Much easier to type as well. ;-)

Destructive load-detection is very expensive and due to failings
elsewhere can trigger system wide stalls of up to 600ms. A simple
first step to correcting this is not to invoke such an expensive
and destructive load-detection operation automatically.

sil164 and friends are the most common, usually they just need to be
poked once because a fixed configuration is enough for any modes and
clocks, so they worked without this patch if the BIOS had done a good
job on POST. Display couldn't survive a suspend/resume cycle though.
Unfortunately, BIOS scripts are useless here.

Load detection needs the connector wired to a CRTC, when there are no
inactive CRTCs left that means we need to cut some other head off for
a while, causing intermittent flickering.

Create connectors before encoders to avoid having to do another loop across
encoder list whenever we create a new connector.  This allows us to pass
the connector to the encoder creation functions, and avoid using a
create_resources() callback since we can now call it directly.

This can also potentially modify the connector ordering on nv50.  On cards
where the DCB connector and encoder tables are in the same order, things
will be unchanged.  However, there's some cards where the ordering between
the tables differ, and in one case, leads us to naming the connectors
"wrongly".

After thinking it over a lot it made more sense for the core to deal with
the output polling especially so it can notify X.

v2: drop plans for fake connector - per Michel's comments - fix X patch sent to xorg-devel, add intel polled/hpd setting, add initial nouveau polled/hpd settings.

v3: add config lock take inside polling, add intel/nouveau poll init/fini calls

v4: config lock was a bit agressive, only needed around connector list reading.
otherwise it could re-enter.

This makes this code common to both the nv04 and nv50 paths.

For the moment, we keep the previous behaviour with HDMI/eDP connectors
and report them as DVI-D/DP instead.  This will be fixed once the rest
of the code has been fixed to deal with those types.

This adds a drm/kms staging non-API stable driver for GPUs from NVIDIA.

This driver is a KMS-based driver and requires a compatible nouveau
userspace libdrm and nouveau X.org driver.

This driver requires firmware files not available in this kernel tree,
interested parties can find them via the nouveau project git archive.

This driver is reverse engineered, and is in no way supported by nVidia.

Support for nearly the complete range of nvidia hw from nv04->g80 (nv50)
is available, and the kms driver should support driving nearly all
output types (displayport is under development still) along with supporting
suspend/resume.

This work is all from the upstream nouveau project found at
nouveau.freedesktop.org.
