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>
2012-03-13drm/nv50: fix detection of second vram rankBen Skeggs
Goes a long way to correcting NVS295 memory reclocking issues. Signed-off-by: Ben Skeggs <bskeggs@redhat.com> Signed-off-by: Martin Peres <martin.peres@labri.fr>
2012-03-13drm/nouveau/pm: implement DDR2/DDR3/GDDR3/GDDR5 MR generation and validationRoy Spliet
Roy Spliet: - Implement according to specs - Simplify - Make array for mc latency registers Martin Peres: - squash and split all the commits from Roy - rework following Ben Skeggs comments - add a form of timings validation - store the initial timings for later use Ben Skeggs - merge slightly modified tidy-up patch with this one - remove perflvl-dropping logic for the moment Signed-off-by: Roy Spliet <r.spliet@student.tudelft.nl> Signed-off-by: Martin Peres <martin.peres@labri.fr> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2012-03-13drm/nv50: hopefully handle the DDR2/DDR3 memtype detection somewhat betterBen Skeggs
M version 2 appears to have a table with some form of memory type info available. NVIDIA appear to ignore the table information except for this DDR2/DDR3 case (which has the same value in 0x100714). My guess is this is due to some of the supported memory types not being represented in the table. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2012-03-13drm/nv50: add memory type detectionBen Skeggs
DDR1/DDR[23] confirmed on NVA8 (see note about DDR3 in source) by changing the value and watching the binary driver's behaviour. GDDR3/4 values confirmed on a NV96 via the same method above. That GDDR4 is present is interesting, as far as I can see no boards using it were ever released. GDDR5 value is based on VBIOS images of known GDDR5 boards.

2011-11-10drm/nv50/vram: fix incorrect detection of bank count on newer chipsetsBen Skeggs
NVA3+ has an extra bit here compared to NV50:NVA3 chipsets. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2011-06-23drm/nouveau: rework vram init/fini ordering a littleBen Skeggs
Commit "drm/nouveau: add some debug output if nouveau_mm busy at destroy time" revealed an issue where vram mm takedown would actually fail due to there still being nodes present, causing nouveau to leak a small amount of memory on module unload. This splits TTM/nouveau_mm a bit more cleanly and ensures nouveau_mm fini isn't done until all gpuobjs are also destroyed. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2011-02-25drm/nouveau: rename nouveau_vram to nouveau_memBen Skeggs
This structure will also be used for GART in the near future. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2010-12-21drm/nouveau: sizeof() vs ARRAY_SIZE()Dan Carpenter
ARRAY_SIZE() was intended here, sizeof() is too large. Signed-off-by: Dan Carpenter <error27@gmail.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2010-12-08drm/nouveau: kick vram functions out into an "engine"Ben Skeggs
NVC0 will be able to share some of nv50's paths this way. This also makes it the card-specific vram code responsible for deciding if a given set of tile_flags is valid, rather than duplicating the allowed types in nv50_vram.c and nouveau_gem.c Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2010-12-08drm/nv50: implement custom vram mmBen Skeggs
This is required on nv50 as we need to be able to have more precise control over physical VRAM allocations to avoid buffer corruption when using buffers of mixed memory types. This removes some nasty overallocation/alignment that we were previously using to "control" this problem. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
