2011-07-24drm/nouveau/gr: disable fifo access and idle before suspend ctx unloadBen Skeggs
Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2011-07-24drm/nouveau: pass flag to engine fini() method on suspendBen Skeggs
It may not be necessary to fail in certain cases (such as failing to idle) on module unload, whereas on suspend it's important to ensure a consistent state can be restored on resume. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2011-07-24drm/nouveau: replace nv04_graph_fifo_access() use with direct reg bashingBen Skeggs

2011-05-16drm/nv04/gr: move to exec engine interfacesBen Skeggs
Like nv10-nv50, needs cleanup. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2010-12-08drm/nv04-nv10: Don't re-enable FIFO access multiple times after IRQ dispatch.Francisco Jerez
nvxx_graph_isr is already taking care of it. In some cases this could've made you miss PGRAPH interrupts (e.g. when you were supposed to get several IRQs of the same kind in a row). Signed-off-by: Francisco Jerez <currojerez@riseup.net> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2010-12-03drm/nouveau: Implement the pageflip ioctl.Francisco Jerez
nv0x-nv4x should be mostly fine, nv50 doesn't work yet. Signed-off-by: Francisco Jerez <currojerez@riseup.net> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2010-12-03drm/nouveau: only expose the object classes that are supported by the chipsetBen Skeggs
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>
2010-12-03drm/nouveau: store engine type in gpuobj class structsBen Skeggs
We will eventually want to address hw engines other than PGRAPH. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2010-12-03drm/nouveau: Refactor context destruction to avoid a lock ordering issue.Francisco Jerez
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.

2010-01-11drm/nouveau: Use the software object for fencing.Francisco Jerez
This should avoid a race condition on nv0x, if we're doing it with actual PGRAPH objects and a there's a fence within the FIFO DMA fetch area when a context switch kicks in. In that case we get an ILLEGAL_MTHD interrupt as expected, but the values in PGRAPH_TRAPPED_ADDR aren't calculated correctly and they're almost useless (e.g. you can see ILLEGAL_MTHDs for the now inactive channel, with a wrong offset/data pair).

2009-12-11drm/nouveau: Add DRM driver for NVIDIA GPUsBen Skeggs
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.
