2013-04-26drm/nouveau/mc: handle irq-related setup ourselvesBen Skeggs
We need to be able to process interrupts before the DRM code is able to actually enable them, set it up ourselves. Also, it's less convoluted to *not* use the DRM wrappers it appears... Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2013-02-20drm/nouveau/pbus: add a PBUS subdev that hands IRQs to the right subdevsMartin Peres
We are going to use PTHERM's IRQs for thermal monitoring but we need to route them first. On nv31-50, PBUS's IRQ line is shared with GPIOs IRQs. It seems like nv10-31 GPIO interruptions aren't well handled. I kept the original behaviour but it is wrong and may lead to an IRQ storm. Since we enable all PBUS IRQs, we need a way to avoid being stormed if we don't handle them. The solution I used was to mask the IRQs that have not been handled. This will also print one message in the logs to let us know. v2: drop the shared intr handler because of was racy v3: style fixes v4: drop a useless construct in the chipset-dependent INTR v5: add BUS to the disable mask v6 (Ben Skeggs): - general tidy to match the rest of the driver's style - nva3->nvc0, nva3 can be serviced just fine with nv50.c, rnndb even notes that the THERM_ALARM bit got left in the hw until fermi anyway.. so, it's not going to conflict - removed the peephole and user stuff, for the moment.. will handle them later if we find a good reason to actually care.. - limited INTR_EN to just what we can handle for now, mostly to prevent spam of unknown status bits (seen on at least nv4x) Signed-off-by: Ben Skeggs <bskeggs@redhat.com> Signed-off-by: Martin Peres <martin.peres@labri.fr>

2012-10-03drm/nouveau: implement module init functions in nouveau_drm.cBen Skeggs
These currently just call the existing ones in nouveau_drv.c, but will be extended in upcoming commits. This needed to be separated from the current code as there will be some header clashes until things are ported. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2012-10-03drm/nouveau: restructure source tree, split core from drm implementationBen Skeggs
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>
