* drm/nv04-nv40: Fix NULL dereference when we fail to find an LVDS native mode.Francisco Jerez2011-02-171-9/+3

* drm/nv04-nv40: Fall back to panel rescaling if we have no usable native mode.Francisco Jerez2010-11-181-6/+7
| | | | | | | | | | This allows the user to set a mode larger than the native one, useful if we had trouble finding the actual native mode (e.g. because it goes above the hardware bandwidth limits).

* drm/nv0x-nv4x: Leave the 0x40 bit untouched when changing CRE_LCD.Francisco Jerez2010-10-051-1/+3
| | | | | | | | It's an unrelated PLL filtering control bit, leave it alone when changing the CRTC-encoder binding. Signed-off-by: Francisco Jerez <currojerez@riseup.net> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

* drm/nv40: Try to set up CRE_LCD even if it has unknown bits set.Francisco Jerez2010-09-241-20/+15
| | | | | | | | | They don't seem to do anything useful, and we really want to program CRE_LCD if we aren't lucky enough to find the right CRTC binding already set. Signed-off-by: Francisco Jerez <currojerez@riseup.net> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

* drm/nv17-nv4x: Attempt to init some external TMDS transmitters.Francisco Jerez2010-08-061-0/+42
| | | | | | | | | | | 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.

* drm/nouveau: tidy connector/encoder creation a littleBen Skeggs2010-07-131-3/+5
| | | | | | | | | | | | | | | 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". Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

* drm/nouveau: Add DRM driver for NVIDIA GPUsBen Skeggs2009-12-111-0/+621
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.
