2019-02-20drm/nouveau: prepare for enabling svm with existing userspace interfacesBen Skeggs1-1/+2
For a channel to make use of SVM features, it requires a different GPU MMU configuration than we would normally use, which is not desirable to switch to unless a client is actively going to use SVM. In order to supporting SVM without more extensive changes to the userspace interfaces, the SVM_INIT ioctl needs to replace the previous configuration safely. The only way we can currently do this safely, accounting for some unlikely failure conditions, is to allocate the new VMM without destroying the last one, and prioritising the SVM-enabled configuration in the code that cares. This will get cleaned up again further down the track. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2019-02-20drm/nouveau: fix missing break in switch statementColin Ian King1-0/+1
The NOUVEAU_GETPARAM_PCI_DEVICE case is missing a break statement and falls through to the following NOUVEAU_GETPARAM_BUS_TYPE case and may end up re-assigning the getparam->value to an undesired value. Fix this by adding in the missing break.

2018-05-18drm/nouveau/fifo/gk104-: require explicit runlist selection for channel ↵Ben Skeggs1-16/+19
allocation We didn't used to be aware that runlist/engine IDs weren't the same thing, or that there was such variability in configuration between GPUs. By exposing this information to a client, and giving it explicit control of which runlist it's allocating a channel on, we're able to make better choices. The immediate effect of this is that on GPUs where CE0 is the "GRCE", we will now be allocating a copy engine running asynchronously to GR for BO migrations - as intended.

2017-11-02drm/nouveau/core/mm: have users explicitly define heap identifiersBen Skeggs1-1/+1
Different sections of VRAM may have different properties (ie. can't be used for compression/display, can't be mapped, etc). We currently already support this, but it's a bit magic. This change makes it more obvious where we're allocating from. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2015-08-28drm/nouveau/nvif: simplify and tidy library interfacesBen Skeggs1-80/+54
A variety of tweaks to the NVIF library interfaces, mostly ripping out things that turned out to be not so useful. - Removed refcounting from nvif_object, callers are expected to not be stupid instead. - nvif_client is directly reachable from anything derived from nvif_object, removing the need for heuristics to locate it - _new() versions of interfaces, that allocate memory for the object they construct, have been removed. The vast majority of callers used the embedded _init() interfaces. - No longer storing constructor arguments (and the data returned from nvkm) inside nvif_object, it's more or less unused and just wastes memory.

2015-08-28drm/nouveau/tmr: type-safe PTIMER-based delay/wait macrosBen Skeggs1-2/+1
These require an explicit struct nvkm_device pointer, unlike the previous macros which take a void *, and work for (almost) anything derived from nvkm_object by using some heuristics. These macros are more general than the previous ones, and can be used to handle PTIMER-based busy-waits (will be used in later devinit fixes) as well as more complicated wait conditions.

2015-01-22drm/nouveau: finalise nvkm namespace switch (no binary change)Ben Skeggs1-8/+8
The namespace of NVKM is being changed to nvkm_ instead of nouveau_, which will be used for the DRM part of the driver. This is being done in order to make it very clear as to what part of the driver a given symbol belongs to, and as a minor step towards splitting the DRM driver out to be able to stand on its own (for virt). Because there's already a large amount of churn here anyway, this is as good a time as any to also switch to NVIDIA's device and chipset naming to ease collaboration with them. A comparison of objdump disassemblies proves no code changes. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2015-01-22drm/nouveau/nvif: namespace of nvkm accessors (no binary change)Ben Skeggs1-5/+5

2014-12-02drm/nouveau: teach nouveau_bo_pin() how to force a contig vram allocationBen Skeggs1-1/+1
We have the ability to move buffers around in the kernel if necessary, and should probably use it rather than failing if userspace passes us a non-contig buffer for a plane. The NOUVEAU_GEM_TILE_NONCONTIG flag from userspace will become a mere initial placement hint once all the relevant paths have been updated. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
