2018-12-11drm/nouveau/fifo/gf100-: call into BAR to reset BARs after MMU faultBen Skeggs
This is needed for Turing, but we're supposed to wait for completion after re-writing the value on older GPUs anyway. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-11-02drm/nouveau/fifo/gf100-: use new interfaces for vmm operationsBen Skeggs
Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-11-02drm/nouveau/core/memory: add reference countingBen Skeggs
We need to be able to prevent memory from being freed while it's still mapped in a GPU's address-space. Will be used by upcoming MMU changes. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-11-02drm/nouveau/core/memory: change map interface to support upcoming mmu changesBen Skeggs
Map flags (access, kind, etc) are currently defined in either the VMA, or the memory object, which turns out to not be ideal for things like suballocated buffers, etc. These will become per-map flags instead, so we need to support passing these arguments in nvkm_memory_map().

2017-11-02drm/nouveau/bar: modify interface to bar1 vmm mappingBen Skeggs
Upcoming changes will remove the nvkm_vmm pointer from nvkm_vma, instead requiring it to be explicitly specified on each operation. It's not currently possible to get this information for BAR1 mappings, so let's fix that ahead of time. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-02-17drm/nouveau/fifo/gf100-: provide notification to user if channel is killedBen Skeggs
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/core/memory: distinguish between coherent/non-coherent targetsBen Skeggs
Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2016-12-13drm/nouveau/fifo/gf100-: recover from host mmu faultsBen Skeggs
This has been on the TODO list for a while now, recovering from things such as attempting to execute a push buffer or touch a semaphore in an unmapped memory area. The only thing required on the HW side here is that the offending channel is removed from the runlist, and *not* a full reset of PFIFO. This used to be a bit messier to handle before the rework to make use of engine topology info, but is apparently now trivial. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2016-03-14drm/nouveau/fifo/gf100: rename spooon to pbdma, and move detection to oneinitBen Skeggs
Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2016-03-14drm/nouveau/fifo/gf100: take runlist target into accountAlexandre Courbot
Bits 28:29 of RUNLIST_BASE specify the memory target of the runlist. Set it to 0x3 (SYS_MEM_NONCOHERENT) if the runlist object resides in system memory. Signed-off-by: Alexandre Courbot <acourbot@nvidia.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

This is purely preparation for upcoming commits, there should be no code changes here. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2015-01-22drm/nouveau/fifo: namespace + nvidia gpu names (no binary change)Ben Skeggs
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>
