2012-10-03drm/nouveau: restructure source tree, split core from drm implementationBen Skeggs1-868/+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>
2012-07-26drm/nv50: rename INVALID_QUERY_OR_TEXTURE error to INVALID_OPERATIONMarcin Slusarz1-1/+1
Current name is misleading, because this error can be triggered by other conditions, like changing STRMOUT parameter without disabling STRMOUT first. Signed-off-by: Marcin Slusarz <marcin.slusarz@gmail.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2012-05-24drm/nouveau/fifo: turn all fifo modules into engine modulesBen Skeggs1-1/+3
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>

2012-05-24drm/nouveau/fifo: remove all the "special" engine hooksBen Skeggs1-3/+2
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>
2012-05-24drm/nouveau: create real execution engine for software object classBen Skeggs1-72/+0
Just a cleanup more or less, and to remove the need for special handling of software objects. This removes a heap of documentation on dma/graph object formats. The info is very out of date with our current understanding, and is far better documented in rnndb in envytools git. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2011-04-05drm/nv50: use "nv86" tlb flush method on everything except 0x50/0xacBen Skeggs1-1/+1
It has been reported that this greatly improves (and possibly fixes completely) the stability of NVA3+ chipsets. In traces of my NVA8, NVIDIA now appear to be doing this too. The most recent traces of 0x50 and 0xac I could find don't show NVIDIA checking PGRAPH status on these flushes, so for now, we won't either. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2010-12-03drm/nv50: Keep track of the head a channel is vsync'ing to.Francisco Jerez1-0/+3
In a multihead setup vblank interrupts may end up enabled in both heads. In that case we want to ignore the vblank interrupts coming from the wrong CRTC to avoid tearing and unbalanced calls to drm_vblank_get/put (fdo bug 31074).

2010-12-03drm/nouveau: Refactor context destruction to avoid a lock ordering issue.Francisco Jerez1-0/+11
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.
