9221b01968 gpu: nvgpu: implement HWPM streamout teardown sequence
Implement below functions:

- nvgpu_profiler_quiesce_hwpm_streamout_resident
Teardown sequence when context is resident or in case profiling
session is a device level session.

- nvgpu_profiler_quiesce_hwpm_streamout_non_resident
Teardown sequence when context is non resident

- nvgpu_profiler_quiesce_hwpm_streamout
Generic sequence to call either of above API based on whether
context is resident or not.

Trigger HWPM streamout teardown sequence while unbinding resources
in nvgpu_profiler_unbind_hwpm_streamout()

Add a new HAL gops.gr.is_tsg_ctx_resident to call
gk20a_is_tsg_ctx_resident() from common code.

Implement below supporting HALs for resident teardown sequence:
- gops.perf.pma_stream_enable()
- gops.perf.disable_all_perfmons()
- gops.perf.wait_for_idle_pmm_routers()
- gops.perf.wait_for_idle_pma()
- gops.gr.disable_cau()
- gops.gr.disable_smpc()

b23a114c63 gpu: nvgpu: ensure all perfmon writes are complete after reset
gr_gv100_reset_hwpm_pmm_registers() writes a bunch of registers in
sys/gpc/fbp chiplets to reset perfmons. To ensure all the writes have
completed it is necessary to readback each chiplet's PRI fence register.

Add and use new HAL g->ops.priv_ring.read_pri_fence() to achieve this.

Implement the HAL for gv11b in new source code file
hal/priv_ring/priv_ring_gv11b.c.

dd9298c959 gpu: nvgpu: move perf unit accesses to common.perf unit
Below HALs are implemented in common.gr unit, but they really belong
to common.perf unit since they access registers from perf unit.
gops.gr.init_hwpm_pmm_register()
gops.gr.get_num_hwpm_perfmon()
gops.gr.set_pmm_register()
gops.gr.reset_hwpm_pmm_registers()

Move them to common.perf unit, and update all the code accordingly
gops.perf.init_hwpm_pmm_register()
gops.perf.get_num_hwpm_perfmon()
gops.perf.set_pmm_register()
gops.perf.reset_hwpm_pmm_registers()

Add new HAL gops.gr.get_pm_ctx_buffer_offsets() and set it to
gr_gk20a_get_pm_ctx_buffer_offsets() for all chips.

db20451d0d gpu: nvgpu: fix pmm chiplet offsets
gr_gv100_init_hwpm_pmm_register() and gr_gv100_set_pmm_register() right
now assume common chiplet stride for all sys/fbp/gpc and use common API
g->ops.perf.get_pmm_per_chiplet_offset() to get the stride.

Chiplet strides are same for all partitions only by chance, and future
chip might change that.

Hence add and use below 3 separate HALs to get appropriate strides.
g->ops.perf.get_pmmsys_per_chiplet_offset()
g->ops.perf.get_pmmgpc_per_chiplet_offset()
g->ops.perf.get_pmmfbp_per_chiplet_offset()

Also store sys/fbp/gpc perfmon count in struct gk20a after first query
instead of querying them again and again. Querying the counts from HW
is time consuming.

d020778c55 gpu: nvgpu: reserve pma stream for legacy profiler
Legacy profiler does not reserve PMA stream resource with PM
reservation system. Also, HWPM system reset is separately implemented
in membuf disable path. And it does not even restore perf unit SLCG
prod values.

Allcoate a dummy profiler object for debug session in perfbuf map
path. Free it in perfbuf unmap path.

This has advantage of synchronizing PMA stream reservation with new
profiler stack. And this also leverages HWPM system reset and SLCG
handling code during resource reservation.

Remove explicit HWPM reset from gops.perf.membuf_reset_streaming()
HALs

f34711d3de gpu: nvgpu: split perfbuf initialization
gk20a_perfbuf_map() allocates perfbuf VM, maps the user buffer into new
VM, and then triggers gops.perfbuf.perfbuf_enable(). This HAL then does
following :
- Allocate perfbuf instance block
- Initialize perfbuf instance block
- Reset stream buffer
- Program instance block address in PMA registers
- Program user buffer address into PMA registers

New profiler interface will have it's own API to setup PMA strem, and
it requires above setup to be done in two phases of perfbuf
initialization and then user buffer setup.

Split above functionalities into below functions
- nvgpu_perfbuf_init_vm()
  - Allocate perfbuf VM
  - Call gops.perfbuf.init_inst_block() to initialize perfbuf instance
    block

- gops.perfbuf.init_inst_block()
  - Allocate perfbuf instance block
  - Initialize perfbuf instance block
  - Program instance block address in PMA registers using
    gops.perf.init_inst_block()
  - In case of vGPU, trigger TEGRA_VGPU_CMD_PERFBUF_INST_BLOCK_MGT
    command to gpu server

- gops.perf.init_inst_block()
  - Reset stream buffer
  - Program user buffer address into PMA registers

Also add corresponding cleanup functions as below :
gops.perf.deinit_inst_block()
gops.perfbuf.deinit_inst_block()
nvgpu_perfbuf_deinit_vm()
