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.

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.

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.
