This commit provides the implementation for the new uapi motivated by the
Vulkan API. It allows user mode drivers (UMDs) to:
1) Initialize a GPU virtual address (VA) space via the new
DRM_IOCTL_NOUVEAU_VM_INIT ioctl for UMDs to specify the portion of VA
space managed by the kernel and
Provide the driver indirection iterating over all DRM GPU VA spaces to
enable the common 'gpuvas' debugfs file for dumping DRM GPU VA spaces.

The new VM_BIND UAPI implementation introduced in subsequent commits
will allow asynchronous jobs processing push buffers and emitting fences.
If a job times out, we need a way to recover from this situation. For
now, simply kill the channel to unblock all hung up jobs and signal
userspace that
The new VM_BIND UAPI uses the DRM GPU VA manager to manage the VA space.
Hence, we a need a way to manipulate the MMUs page tables without going
through the internal range allocator implemented by nvkm/vmm.
This patch adds a raw interface for nvkm/vmm to pass the resposibility
for managing the
The new VM_BIND UAPI implementation introduced in subsequent commits
will allow asynchronous jobs processing push buffers and emitting
fences.
If a fence context is killed, e.g. due to a channel fault, jobs which
are already queued for execution might still emit new fences. In such a
case a job
The new (VM_BIND) UAPI exports DMA fences through DRM syncobjs. Hence,
in order to emit fences within DMA fence signalling critical sections
(e.g. as typically done in the DRM GPU schedulers run_job() callback) we
need to separate fence allocation and fence emitting.

Move the usercopy helpers to a common driver header file to make it
usable for the new API added in subsequent commits.

This commit provides the interfaces for the new UAPI motivated by the

1) Initialize a GPU virtual address (VA) space via the new

2) Bind and unbind GPU VA space
This commit adds a function to dump a DRM GPU VA space and a macro for
drivers to register the struct drm_info_list 'gpuvas' entry.
Most likely, most drivers might maintain one DRM GPU VA space per struct
drm_file, but there might also be drivers not having a fixed relation
between DRM GPU VA
Provide a getter function for the client's current vmm context. Since
we'll add a new (u)vmm context for UMD bindings in subsequent commits,
this will keep the code clean.

Add infrastructure to keep track of GPU virtual address (VA) mappings
with a decicated VA space manager implementation.
New UAPIs, motivated by Vulkan sparse memory bindings graphics drivers
start implementing, allow userspace applications to request multiple and
arbitrary GPU VA mappings of

This adds the infrastructure for an execution context for GEM buffers
which is similar to the existing TTMs execbuf util and intended to replace
it in the long term.
The basic functionality is that we abstracts the necessary loop to lock
many different GEM buffers with
This patch series provides a new UAPI for the Nouveau driver in order to
support Vulkan features, such as sparse bindings and sparse residency.
Furthermore, with the DRM GPUVA manager it provides a new DRM core feature to
keep track of GPU virtual address (VA) mappings in a more generic way.
