Add a device node for management of nvs control fifo buffers for
scheduling domains. The current design consists of a master structure
struct nvgpu_nvs_domain_sched_ctrl for management of users as well
as control queues. Initially all users are added as non-exclusive users.

Subsequent changes will add support for IOCTLS to manage opening of
Send/Receive and Event buffers, querying characteristics etc.

In subsequent changes, a user that tries to open a Send/Receive queue
will first try to reserve itself as an exclusive user and only if that
succeeds can proceed with creation of both Send/Receive queues.

Exclusive users will be reset to non-exclusive users just before they
close their device node handle.

3651d1150d gpu: nvgpu: update kmdi interfaces
Patch udpates/fixes following issues.
- Updates nvgpu_dbg_gpu_get_mappings_entry.size to u64 to address >4G
limitations.
- Removes offset from original cpuva and unmaps only original mapped
address.
- Call nvgpu_vm_find_mapped_buf_range() in place of
nvgpu_vm_find_mapped_buf() to find the addresses which are not
page aligned.
- Update logic to parse the gpuva while trying to find gpu mappings so
that gpuva which are more than the mapped buffer base address can also
be considered.

2a8914619d gpu: nvgpu: bind sched domains as fds
Replace id-based lookup with fd-based lookup when binding a TSG to a
domain. The device node based domain interface naturally provides access
control; this way userspace tools can limit which uid/gid can access
each domain.

Also, explicitly disallow binding channels to a TSG that has no runlist
domain yet. Normally a TSG is in the default domain if nothing else has
been specified, but the default domain can be deleted.

3a64fdefc4 gpu: nvgpu: domains as files for access control
Create device nodes for user-created scheduling domains. This helps
leverage filesystem based access control: domains can be chosen to be
available for a limited set of users on a system.

The device nodes are dynamic: they can be removed while the driver is
running normally. This is a bit different from the nodes that exist
until the driver is unloaded, so the devno/domain mapping is stored in a
separate list. The usual container_of pattern would suffer from an
unavoidable race condition if a domain file was opened while the same
domain would get removed.

As usual, domain refcounting prevents a domain from being removed. Now
the open device files hold refs and thus any open domain files prevent a
domain from getting removed, in addition to the userspace-invisible ref
that is taken when a TSG is bound to a domain.

While at it, make the query ioctl guarded by the sched domain mutex, as
domains might technically get added or removed during the querying code.

14ed75e857 gpu: nvgpu: fix REMAP to support small/big pages
Initially, REMAP only worked with big pages but in some cases
only small pages are supported where REMAP functionality is
also needed.

This cleans up some page size assumptions. In particular, on a
remap request, the nvgpu_vm_area is found from the passed in VA,
but can only be done from virt_offset_in_pages if we're also
told the page size.

This now occurs from _PAGESIZE_ flags which are required by
both map and unmap operations.

Add ioctls for creating, removing and querying scheduling domains and
interface with the "nvsched" entity that will be the core scheduler.
Include the scheduler in the Linux build.

The core scheduler code will ultimately hold data on and control what
gets scheduled, but this intermediate layer in nvgpu-rm needs a bit of
bookeeping to manage the userspace interface.

To keep changes isolated, this does not touch the internal runlist
domains yet. The core scheduler logic will eventually control the

ed16377983 gpu: nvgpu: allocate comptags and store metadata in REGISTER_BUFFER ioctl
To enable userspace query about comptags allocation status of a buffer,
comptags are to be allocated only during buffer registration done by
nvrm_gpu. Earlier, they were allocated during map.

nvrm_gpu will be sending metadata blob to be associated with the buffer.
This will have to be stored in the dmabuf privdata for all the buffers
registered by nvrm_gpu.

This patch moves the privdata allocation to buffer registration ioctl.

Remove g->mm.priv_lock as it is not needed now. This lock was added
to protect dmabuf private data setup. That private data is now
handled through dmabuf->ops and setup of dmabuf->ops is done
under dmabuf->lock.

To support legacy userspace, this patch still allocates comptags on
demand on map calls for unregistered buffers.

3cd256b344 gpu: nvgpu: add linux REMAP support
Add REMAP ioctl and accompanying support to the linux nvgpu driver.

REMAP support provides per-page control over sparse VM areas using the
concept of a virtual memory pool.

The REMAP ioctl accepts a list of operations (each a map or unmap) that
modify the VM area pages tracked by the virtual mmemory pool.

Inclusion of REMAP support in the nvgpu build is controlled by the new
CONFIG_NVGPU_REMAP flag.  This flag is enabled by default for linux builds.
A new NVGPU_GPU_FLAGS_SUPPORT_REMAP characteristics flag is added for use
in detecting when REMAP support is available.

When a VM allocation tagged with NVGPU_VM_AREA_ALLOC_SPARSE is made the
base virtual memory pool resources are allocated.  Per-page resources are
later allocated when the NVGPU_AS_IOCTL_REMAP ioctl is issued.  All REMAP
resources are released when the corresponding VM area is freed.
