2012-10-03drm/nouveau: restructure source tree, split core from drm implementationBen Skeggs1-3360/+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>
2012-05-24drm/nv50/gr: make sure NEXT_TO_CURRENT is executed even if nothing doneBen Skeggs1-1/+1

Confirmed to fix random hangs while running all Unegine demos on NV86. Signed-off-by: Maxim Levitsky <maximlevitsky@gmail.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2011-09-20drm/nv50/gr: enable ctxprog xfer only when we need it to save powerMartin Peres1-0/+5
This patch adds instructions to ctxprog and by doing, impacts context switching performance. My testcase showed a 1% performance cost using glxgears that is a context-switch bound application. Please test and report bugs/performance/power/other. Many thanks to Maxim Levitsky for his dedicated work on lowering power consumption with nouveau.

The set will be replaced with a wait on the same flag by a subsequent commit in order to halt a ctxprog's execution temporarily. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2010-03-10drm/nv50: Improve PGRAPH interrupt handling.Marcin Kościelnicki1-4/+4
This makes nouveau recognise and report more kinds of PGRAPH errors, as well as prevent GPU lockups resulting from some of them. Lots of guesswork was involved and some part of this is probably incorrect. Some potential-lockuop situations are handled by just resetting a whole PGRAPH subunit, which doesn't sound like a "proper" solution, but seems to work just fine... for now.
