- Created volt ops under pmu_ver to support volt_set_voltage,
volt_get_voltage & volt_send_load_cmd_to_pmu.
- Renamed volt load, set_voltage & get_voltage gp10x method names.
- Added new volt load, set_voltage & get_voltage methods for gv10x
using RPC & added code to handle ack in pmu_rpc_handler() along
with struct rail_list changes.
- Updated volt ops of gp106 & gv100 to point to respective methods.
- Added member volt_dev_idx_ipc_vmin & volt_scale_exp_pwr_equ_idx to
"struct nv_pmu_volt_volt_rail_boardobj_set" & "struct voltage_rail"
made changes to update members as needed.
- Added member volt_scale_exp_pwr_equ_idx to
"struct vbios_voltage_rail_table_1x_entry" to read
value from VBIOS table & update rail boardobj set interface.
- Defines for volt RPC "NV_PMU_RPC_ID_VOLT_*"
- Define struct's volt load, set_voltage & get_voltage to execute
volt RPC.

- Updated & added new parameter "bool is_copy_back" to
nvgpu_pmu_rpc_execute() to support copy back processed
RPC request from PMU to caller by passing parameter value
true & this blocks method till it receives ACK from PMU
for requested RPC.
- Added "struct rpc_handler_payload" to hold info
required for RPC handler like RPC buff address &
clear memory if copy back is not requested.
- Added define PMU_RPC_EXECUTE_CPB to support to copy back
processed RPC request from PMU to caller.
- Updated RPC callback handler support, crated memory &
assigned default handler if callback is not requested
else use callback parameters data to request to PMU.
- Added define PMU_RPC_EXECUTE_CB to support callback
- Updated pmu_wait_message_cond(), restricted condition
check to 8-bit instead 32-bit condition check.

PMU ucode records supported feature list for a
particular chip as support mask sent
via PMU_PG_PARAM_CMD_GR_INIT_PARAM.
It then enables selective feature list through
enable mask sent via
PMU_PG_PARAM_CMD_SUB_FEATURE_MASK_UPDATE cmd.
Right now only ELPG state machine mask was enabled.
Only ELPG state machine was getting executed
but other crucial steps in ELPG entry/exit sequence
were getting skipped.

PMU ucode is updated to include engine ID in the
PG messages sent from PMU to gpu driver.
Right now we were getting random values from the PMU ucode
as it uses ELPG msg structure without initializing.
It further causes incorrect values of ELPG state variables
maintained in the nvgpu driver.

"pmu_perfmon_start_sampling",
"pmu_perfmon_stop_sampling" and
"pmu_perfmon_get_samples" in pmu ops
to differenciate for chips using RPC & legacy
cmd/msg mechanism.
- Defined and used PERFMON RPC commands for t19x
- INIT
- START
- STOP
- QUERY
- Adds RPC handler for PERFMON RPC commands.
- For guerying GPU utilization/load, we need to send PERFMON_QUERY
RPC command for gv11b.
- Enables perfmon for gv11b.

Maintain a list of boardobj and boardobjgrp, so that we can free
related objects when removing pmu support. A flag is added in
boardobj so that the destructor can determine if it should free
the object. This 'allocated' flag is false when the object is
embedded into another structure, which should be freed through
other means.

PMU response(intr callback for messages) can run faster
than the kthread posting commands to PMU.
This causes the PMU message callback to skip important pmu
state change(which happens just after the PMU command is posted).
Solution:
State change should be triggered from only inside the intr callback.
Other places can only update the pmu_state variable.
This change also adds error check to print in case command post fails.

The Pg init task hogs the kernel by having a wait condition with no timeout
waiting for pg state change, but ps state may not post a change in a long time
depending on runtime conditions, so we get soft-crashes warning spews in the

We solve this by making the condition wait interruptible

This change solves crashes during bind that were introduced in the driver
during the OS unification refactoring due to lack of coverage of the remove()
function.
The fixes during remove are:
(1) Prevent NULL dereference on GPUs with secure boot
(2) Prevent NULL dereferences when fecs_trace is not enabled
(3) Added PRAMIN blocker during driver removal if HW is no longer accesible
(4) Prevent double free of debugfs nodes as they are handled on the
debugfs_remove_recursive() call
(5) quiesce() can now be called without checking is HW accesible flag is set
(6) added function to free irq so no IRQ association is left on the driver after
it is removed
(7) prevent NULL dereference on nvgpu_thread_stop() if the thread is already
stopped

msleep is not recommended for (1ms - 20ms). So use usleep_range
instead to have a more deterministic sleep time.
Also fix the print for target_ref_count that could either be 2 or
1 based on whether GPU rail-gating is enabled or not.

When the pmu reaches PMU_STATE_STARTED, exit from the nvgpu_pg_init_task
thread as it's no longer necessary. This prevents a possibly long wait
on the signaling condition, which would make Linux think that the thread
has been blocked and print a warning.
