2017-04-06drm/nouveau: initial support (display-only) for GP107Ben Skeggs1-0/+30
Forked from GP106 implementation. Split out from commit enabling secboot/gr support so that it can be added to earlier kernels. Cc: stable@vger.kernel.org [4.10+] Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-04-06drm/nouveau/kms/nv50: fix double dma_fence_put() when destroying plane stateBen Skeggs1-2/+0
When the atomic support was added to nouveau, the DRM core did not do this. However, later in the same merge window, a commit (drm/fence: add in-fences support) was merged that added it, leading to use-after-frees of the fence object.

2017-04-06drm/nouveau/mmu/nv4a: use nv04 mmu rather than the nv44 oneIlia Mirkin1-1/+1
The NV4A (aka NV44A) is an oddity in the family. It only comes in AGP and PCI varieties, rather than a core PCIE chip with a bridge for AGP/PCI as necessary. As a result, it appears that the MMU is also non-functional. For AGP cards, the vast majority of the NV4A lineup, this worked out since we force AGP cards to use the nv04 mmu. However for PCI variants, this did not work. Switching to the NV04 MMU makes it work like a charm. Thanks to mwk for the suggestion. This should be a no-op for NV4A AGP boards, as they were using it already.

git://people.freedesktop.org/~airlied/linux Pull drm updates from Dave Airlie: "This is the main drm pull request for v4.11. Nothing too major, the tinydrm and mmu-less support should make writing smaller drivers easier for some of the simpler platforms, and there are a bunch of documentation updates. Intel grew displayport MST audio support which is hopefully useful to people, and FBC is on by default for GEN9+ (so people know where to look for regressions). AMDGPU has a lot of fixes that would like new firmware files installed for some GPUs. Other than that it's pretty scattered all over. I may have a follow up pull request as I know BenH has a bunch of AST rework and fixes and I'd like to get those in once they've been tested by AST, and I've got at least one pull request I'm just trying to get the author to fix up.

2017-02-17drm/nouveau/fifo/gk104-: trigger mmu fault before attempting engine recoveryBen Skeggs1-0/+41
Greatly improves the chances of recovering the GPU from a CTXSW_TIMEOUT. Tested with piglit's arb_shader_image_load_store-atomicity, which causes GR to hang in such a way that recovery failed (CTXSW_TIMEOUT continually re-triggers). Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2017-02-17drm/nouveau/core: add engine method to assist in determining chsw directionBen Skeggs2-0/+10
FIFO gives us load/save/switch status, and we need to be able to determine which direction a "switch" is failing during channel recovery. In order to do this, we apparently need to query the engine itself. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2017-02-17drm/nouveau/fifo/gf100-: provide notification to user if channel is killedBen Skeggs11-5/+58
There are instances (such as non-recoverable GPU page faults) where NVKM decides that a channel's context is no longer viable, and will be removed from the runlist. This commit notifies the owner of the channel when this happens, so it has the opportunity to take some kind of recovery action instead of hanging. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2017-02-17drm/nouveau/drm/nouveau/led: prevent a possible use-after-freeMartin Peres1-0/+1
If the led class registration fails, we free drm->led but do not reset it to NULL, which means that the suspend/resume/fini function will act as if everything went well in init() and will likely crash the kernel. This patch adds the missing drm->led = NULL.

2017-02-17drm/nouveau/core/client: allow creation of subclientsBen Skeggs9-35/+140
We want a supervisor client of NVKM (such as the DRM) to be able to allow sharing of resources (such as memory objects) between clients. To allow this, the supervisor creates all its clients as children of itself, and will use an upcoming ioctl to permit sharing. Currently it's not possible for indirect clients to use subclients. Supporting this will require an additional field in the main ioctl. This isn't important currently, but will need to be fixed for virt. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
