2012-03-13drm/nv20-nv40: add memory type detectionBen Skeggs1-0/+45
NV20/NV30 is partially educated guesswork at this point, based on any information around about available memory types and a horribly unspeakable amount of vbios image scouring. I'm not entirely certain the GDDR3 define is correct, I have not spotted a single vbios with that value yet (though it is mentioned in some 1218-using nv4x vbios), but there are reports that some nv3x did use it.. NV40(100914) confirmed by switching an NV49 to DDR1/DDR2 values and making sure that the binary driver behaviour showed it had detected DDR1/DDR2 instead of GDDR3 before dying horribly. NV40(100474) confirmed by doing much the same task as above on an NV44, except this was *much* easier as changing the values didn't seem to have any noticable effect on the memory controller aside from changing the binary driver's behaviour.

2011-02-24drm/nv40: implement support for on-chip PCIEGARTBen Skeggs1-6/+53
v2. moved nv44 pciegart table back to instmem, where it's not accessible by userspace clients. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2010-12-03drm/nouveau: Rework tile region handling.Francisco Jerez1-13/+9
The point is to share more code between the PFB/PGRAPH tile region hooks, and give the hardware specific functions a chance to allocate per-region resources. Signed-off-by: Francisco Jerez <currojerez@riseup.net> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2009-12-11drm/nouveau: Add DRM driver for NVIDIA GPUsBen Skeggs1-0/+62
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.
