* drm/nouveau: remove remnants of nouveau_pgraph_engineBen Skeggs2011-05-15
| | | | Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
* drm/nv50/gr: move to exec engine interfacesBen Skeggs2011-05-15
| | | | | | | This needs a massive cleanup, but to catch bugs from the interface changes vs the engine code cleanup, this will be done later. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
* drm/nouveau: working towards a common way to represent enginesBen Skeggs2011-05-15
| | | | | | | | | | | There's lots of more-or-less independant engines present on NVIDIA GPUs these days, and we generally want to perform the same operations on them. Implementing new ones requires hooking into lots of different places, the aim of this work is to make this simpler and cleaner. NV84:NV98 PCRYPT moved over as a test.

* drm/nv50-nvc0: initialise display sync channelsBen Skeggs2011-02-24
| | | | | | | Also imports a couple of helper functions that'll be used to implement page flipping in the following commits.. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
* drm/nouveau: introduce new gart type, and name _SGDMA more appropriatelyBen Skeggs2011-02-24
| | | | | | | In preparation for the addition of a new nv40 backend, we'll need to be able to distinguish between a paged dma object and the on-chip GART. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
* drm/nouveau: don't munge in drm_mm internalsDaniel Vetter2011-02-22
| | | | | | | | | | Nouveau was checking drm_mm internals on teardown to see whether the memory manager was initialized. Hide these internals in a small inline helper function.

* drm/nouveau: Synchronize with the user channel before GPU object destruction.Francisco Jerez2010-12-07
| | | | | | | | | | | | | | There have been reports of PFIFO cache errors during context take down (fdo bug 31637). They are caused by some GPU objects being taken out while the channel is still potentially processing commands. Make sure that all the previous rendering has landed before releasing a GPU object.

| | | | | | | We previously added all the available classes for the entire generation, even though the objects wouldn't work on the hardware. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
* drm/nouveau: use object class structs more extensivelyBen Skeggs2010-12-03
| | | | | | | The structs themselves, as well as the non-sw object creation function are probably very misnamed now. That's a problem for later :) Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

* drm/nouveau: Add DRM driver for NVIDIA GPUsBen Skeggs2009-12-11
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.
