c6b846d34c gpu: nvgpu: add gops.semaphore_wakeup HAL
vserver handles semaphore differently from native, so it needs a
callback to differentiate from native. Also created common function
mc_gk20a_handle_intr_nonstall to handle all nonstall interrupts.

2f2e51bbae gpu: nvgpu: Use gv11b_css_hw_set_handled_snapshots for GV11B
The value of NV_PERF_PMASYS_MEM_BUMP is different for Volta
and NVGPU_IOCTL_CHANNEL_CYCLE_STATS_SNAPSHOT_CMD_FLUSH did not
have correct behavior on GV11B due to that.
The patch adds an instance of css_hw_set_handled_snapshots
for Volta to fix that.
The patch also renames css_hw_set_handled_snapshots
to gk20a_css_hw_set_handled_snapshots to make it more clear
that the function is arch dependent.

f0cbe19b12 gpu: nvgpu: add user API to get read-only syncpoint address map
Add User space API NVGPU_AS_IOCTL_GET_SYNC_RO_MAP to get read-only syncpoint
address map in user space

We already map whole syncpoint shim to each address space with base address
being vm->syncpt_ro_map_gpu_va

This new API exposes this base GPU_VA address of syncpoint map, and unit size
of each syncpoint to user space.
User space can then calculate address of each syncpoint as
syncpoint_address = base_gpu_va + (syncpoint_id * syncpoint_unit_size)

Note that this syncpoint address is read_only, and should be only used for
inserting semaphore acquires.
Adding semaphore release with this address would result in MMU_FAULT

Define new HAL g->ops.fifo.get_sync_ro_map and set this for all GPUs supported
on Xavier SoC

b386768d32 gpu: nvgpu: make .tsg_unbind_channel one layer lower
The message to tell RM server to unbind channel has to be sent after
client unbinds the channel and before client calls tsg release. The
channel has to belong to a tsg on RM server before client submit a
runlist to remove the channel. Or there's a bare channel problem.

By moving .tsg_unbind_channl one layer lower, gk20a_tsg_unbind_channel()
will be common functions for all chip, and it'll call tsg release after
call .tsg_unbind_channel. So vgpu won't need to worry about tsg was
released before sending msg to RM server.

fuse override functions did the same thing, so delete the HAL and
call the same function to read the DT overrides on all chips.

Also remove the fuse override functionality from dGPU. There are no
DT entries for PCIe devices, so it would've failed anyway.

31e594befe gpu: nvgpu: Split ctxsw_trace API into non-Linux component
Split the ctxsw trace "core" API code into <nvgpu/ctxsw_trace.h>. This
is not perect though since there's some Linuxisms present in the HAL
and as such that code has to be hidden by the ctxsw tracing CONFIG. But
this patch should work for QNX such that it will allow the code to
build as long as CONFIG_GK20A_CTXSW_TRACE is not set.

Also fix the copywrite notice in the ctxsw code present under
common/linux to be GPL.

4d2d890c01 gpu: nvgpu: Move ctxsw_trace_gk20a.c to common/linux
Migrate ctxsw_trace_gk20a.c to common/linux/ctxsw_trace.c. This
has been done becasue the ctxsw tracing code is currently too
tightly tied to the Linux OS due to usage of a couple system calls:

  - poll()
  - mmap()

And general Linux driver framework code. As a result pulling the
logic out of the FECS tracing code is simply too large a scope for
time time being.

Instead the code was just copied as much as possible. The HAL ops
for the FECS code was hidden behind the FECS tracing config so
that the vm_area_struct is not used when QNX does not define said
config. All other non-HAL functions called by the FECS ctxsw
tracing code ha now also been hidden by this config. This is not
pretty but for the time being it seems like the way to go.

Add max_css_buffer_size to gpu characteristics. In the virtual
case, the size of the cycle stats snapshot buffer is constrained
by the size of the mempool shared between the guest OS and the
RM server, so tools need to find out what is the maximum size
allowed.

In the native case, we return 0xffffffff to indicate
that the buffer size is unbounded (subject to memory availability),
in the virtual case we return the size of the mempool.

Also collapse native init_cyclestats functions to a single version,
as each chip had identical versions of the code.

2a285d0607 gpu: nvgpu: Cleanup generic MM code in gk20a/mm_gk20a.c
Move much of the remaining generic MM code to a new common location:
common/mm/mm.c. Also add a corresponding <nvgpu/mm.h> header. This
mostly consists of init and cleanup code to handle the common MM
data structures like the VIDMEM code, address spaces for various
engines, etc.

A few more indepth changes were made as well.

1. alloc_inst_block() has been added to the MM HAL. This used to be
   defined directly in the gk20a code but it used a register. As a
   result, if this register hypothetically changes in the future,
   it would need to become a HAL anyway. This path preempts that
   and for now just defines all HALs to use the gk20a version.

2. Rename as much as possible: global functions are, for the most
   part, prepended with nvgpu (there are a few exceptions which I
   have yet to decide what to do with). Functions that are static
   are renamed to be as consistent with their functionality as
   possible since in some cases function effect and function name
   have diverged.

We right now remove a channel from TSG list and disable all the channels in
TSG while removing a channel from TSG
With this sequence if any one channel in TSG is closed, rest of the channels
are set as timed out and cannot be used anymore

We need to fix this sequence as below to allow removing a channel from active
TSG so that rest of the channels can still be used

- disable all channels of TSG
- preempt TSG
- check if CTX_RELOAD is set if support is available
  if CTX_RELOAD is set on channel, it should be moved to some other channel
- check if FAULTED is set if support is available
- if NEXT is set on channel then it means channel is still active
  print out an error in this case for the time being until properly handled
- remove the channel from runlist
- remove channel from TSG list
- re-enable rest of the channels in TSG
- clean up the channel (same as regular channels)

Add below fifo operations to support checking channel status
g->ops.fifo.tsg_verify_status_ctx_reload
g->ops.fifo.tsg_verify_status_faulted

Define ops.fifo.tsg_verify_status_ctx_reload operation for gm20b/gp10b/gp106
as gm20b_fifo_tsg_verify_status_ctx_reload()
This API will check if channel to be released has CTX_RELOAD set, if yes
CTX_RELOAD needs to be moved to some other channel in TSG

Remove static from channel_gk20a_update_runlist() and export it
