* drm/nouveau: allocate fixed amount of PRAMIN per channel on all chipsetsBen Skeggs2010-07-131-28/+8
| | | | | | | | Previously only done on nv50+ This commit also switches unknown NV2x/NV3x chipsets to noaccel mode. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
* drm/nouveau: add instmem flush() hookBen Skeggs2010-07-131-33/+12
| | | | | | | | | | This removes the previous prepare_access() and finish_access() hooks, and replaces it with a much simpler flush() hook. All the chipset-specific code before nv50 has its use removed completely, as it's not required there at all. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
* drm/nouveau: remove dev_priv->init_state and friendsBen Skeggs2010-07-131-2/+0
| | | | | | | Nouveau will no longer load at all if card initialisation fails, so all these checks are unnecessary. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

| | | | | | | | It will be useful for various synchronization purposes, mostly stolen from "[PATCH] drm/nv50: synchronize user channel after buffer object move on kernel channel" by Maarten Maathuis. Signed-off-by: Francisco Jerez <currojerez@riseup.net>
* drm/nouveau: Add DRM driver for NVIDIA GPUsBen Skeggs2009-12-111-0/+1294
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.
