2017-12-19drm/nouveau: use alternate memory type for system-memory buffers with kind != 0Ben Skeggs
Fixes bug on Tegra where we'd strip kind information from system memory (ie. all) buffers, resulting in misrendering. Behaviour on dGPU should be unchanged.

2017-11-02drm/nouveau: remove explicit unmapsBen Skeggs
If the VMA is being deleted, we don't need to explicity unmap first anymore. The MMU code will automatically merge the operations into a single page tree walk. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-11-02drm/nouveau/mmu: remove support for old backendsBen Skeggs
Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-11-02drm/nouveau: allocate vram with nvkm_ram_get()Ben Skeggs
This will cause a subtle behaviour change on GPUs that are in mixed-memory configurations in that VRAM in the degraded section of VRAM will no longer be used for TTM buffer objects. That section of VRAM is not meant to be used for displayable/compressed surfaces, and we have no reliable way with the current interfaces to be able to make that decision properly. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-11-02drm/nouveau: directly handle comptag allocationBen Skeggs
Another transition step to allow finer-grained patches transitioning to new MMU backends. Old backends will continue operate as before (accessing nvkm_mem::tag), and new backends will get a reference to the tags allocated here. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-11-02drm/nouveau: wrap nvkm_mem objects in nvkm_memory interfacesBen Skeggs
This is a transition step, to enable finer-grained commits while transitioning to new MMU interfaces. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2012-10-03drm/nouveau: port all engines to new engine module formatBen Skeggs
This is a HUGE commit, but it's not nearly as bad as it looks - any problems can be isolated to a particular chipset and engine combination. It was simply too difficult to port each one at a time, the compat layers are *already* ridiculous. Most of the changes here are simply to the glue, the process for each of the engine modules was to start with a standard skeleton and copy+paste the old code into the appropriate places, fixing up variable names etc as needed. v2: Marcin Slusarz <marcin.slusarz@gmail.com> - fix find/replace bug in license header v3: Ben Skeggs <bskeggs@redhat.com> - bump indirect pushbuf size to 8KiB, 4KiB barely enough for userspace and left no space for kernel's requirements during GEM pushbuf submission. - fix duplicate assignments noticed by clang v4: Marcin Slusarz <marcin.slusarz@gmail.com> - add sparse annotations to nv04_fifo_pause/nv04_fifo_start - use ioread32_native/iowrite32_native for fifo control registers v5: Ben Skeggs <bskeggs@redhat.com> - rebase on v3.6-rc4, modified to keep copy engine fix intact - nv10/fence: unmap fence bo before destroying - fixed fermi regression when using nvidia gr fuc - fixed typo in supported dma_mask checking 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>
2012-05-24drm/nouveau/fifo: turn all fifo modules into engine modulesBen Skeggs
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 Skeggs
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>

2012-03-13drm/nouveau/pm: track mr2 for gddr3Ben Skeggs

2012-03-13drm/nouveau/pm: introduce ram reclocking helperBen Skeggs
This will probably result in more lines of code, however, we're going to have at least 3 slightly different implementations of this very soon and I'd rather keep the ram reclocking logic separate from the hw specifics. DDR2/DDR3/GDDR3 implemented thus far, others will be added as necessary. Signed-off-by: Ben Skeggs <bskeggs@redhat.com> Signed-off-by: Martin Peres <martin.peres@labri.fr>

2012-03-13drm/nouveau/pm: calculate memory timings at perflvl creation timeBen Skeggs
Statically generating the PFB register and MR values for each timing set turns out to be insufficient. There's at least one (so far) known piece of information which effects MR values which is stored in the perflvl entry on some chipsets (and in another table on later ones), which is disconnected from the timing table entries. After this change we will generate a timing set based on an input clock frequency instead, and have this data stored in the performance level data.

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>

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>
