2011-02-24drm/nv50: drop explicit yields in favour of smaller PFIFO timesliceBen Skeggs1-1/+2
This gives a small, but noticeable performance gain at lower performance levels, and unchanged at the higher ones. With this commit, we're now using the same timeslice size as the NVIDIA binary driver currently does, and dropping an unknown bit that NVIDIA no longer appear to set.

2010-12-08drm/nouveau: make fifo.create_context() responsible for mapping control regsBen Skeggs1-0/+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>

2010-12-03drm/nouveau: Refactor context destruction to avoid a lock ordering issue.Francisco Jerez1-0/+17
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.

2010-07-13drm/nouveau: add instmem flush() hookBen Skeggs1-12/+3
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>
2010-02-25drm/nv50: switch to indirect push buffer controlsBen Skeggs1-4/+4
PFIFO on G80 and up has a new mode where the main ring buffer is simply a ring of pointers to indirect buffers containing the actual command/data packets. In order to be able to implement index buffers in the 3D driver we need to be able to submit data-only push buffers right after the cmd packet header, which is only possible using the new command submission method. This commit doesn't make it possible to implement index buffers yet, some userspace interface changes will be required, but it does allow for testing/debugging of the hardware-side support in the meantime.

2010-02-25drm/nouveau: protect channel create/destroy and irq handler with a spinlockMaarten Maathuis1-0/+5
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). Signed-off-by: Maarten Maathuis <madman2003@gmail.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2010-02-10drm/nv50: delete ramfc object after disabling fifo, not beforeMaarten Maathuis1-3/+6

2009-12-11drm/nouveau: Add DRM driver for NVIDIA GPUsBen Skeggs1-0/+494
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.
