* drm/nouveau: restructure source tree, split core from drm implementationBen Skeggs2012-10-031-506/+0
| | | | | | | | | | | | | | Future work will be headed in the way of separating the policy supplied by the nouveau drm module from the mechanisms provided by the driver core. There will be a couple of major classes (subdev, engine) of driver modules that have clearly defined tasks, and the further directory structure change is to reflect this. No code changes here whatsoever, aside from fixing up a couple of include file pathnames. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
* drm/nouveau/fifo: turn all fifo modules into engine modulesBen Skeggs2012-05-241-186/+181
| | | | | | | | | | | | | Been tested on each major revision that's relevant here, but I'm sure there are still bugs waiting to be ironed out. This is a *very* invasive change. There's a couple of pieces left that I don't like much (eg. other engines using fifo_priv for the channel count), but that's an artefact of there being a master channel list still. This is changing, slowly. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
* drm/nouveau/fifo: remove all the "special" engine hooksBen Skeggs2012-05-241-46/+14
| | | | | | | | | | | All the places this stuff is actually needed tends to be chipset-specific anyway, so we're able to just inline the register bashing instead. The parts of the common code that still directly touch PFIFO temporarily have conditionals, these will be removed in subsequent commits that will refactor the fifo modules into engine modules like graph/mpeg etc. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

* drm/nouveau: make fifo.create_context() responsible for mapping control regsBen Skeggs2010-12-081-0/+9
| | | | | | | | The regs belong to PFIFO, they're different for pretty much the same generations we need different PFIFO control for, and NVC0 is going to be even more different than the rest. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

* drm/nouveau: Refactor context destruction to avoid a lock ordering issue.Francisco Jerez2010-12-031-2/+19
| | | | | | | | | | | | | | | | The destroy_context() engine hooks call gpuobj management functions to release the channel resources, these functions use HARDIRQ-unsafe locks whereas destroy_context() is called with the HARDIRQ-safe context_switch_lock held, that's a lock ordering violation. Push the engine-specific channel destruction logic into destroy_context() and let the hardware-specific code lock and unlock when it's actually needed. Change the engine destruction order to avoid a race in the small gap between pgraph and pfifo context uninitialization.

* drm/nouveau: Simplify tile region handling.Francisco Jerez2010-09-241-25/+20
| | | | | | | | | Instead of emptying the caches to avoid a race with the PFIFO puller, go straight ahead and try to recover from it when it happens. Also, kill pfifo->cache_flush and tile->lock, we don't need them anymore. Signed-off-by: Francisco Jerez <currojerez@riseup.net> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

| | | | | | | | | | 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>

| | | | | | | | | The nv50 pgraph handler (for example) could reenable pgraph fifo access and that would be bad when pgraph context is being unloaded (we need the guarantee a ctxprog isn't running).

* drm/nouveau: Add DRM driver for NVIDIA GPUsBen Skeggs2009-12-111-0/+271
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.
