97762279b7 gpu: nvgpu: make nvgpu_init_mutex return void
Make the nvgpu_init_mutex function return void.
In linux case, this doesn't affect anything since mutex_init
returns void.
For posix, we assert() and die if pthread_mutex_init fails.

This alleviates the need to error inject for _every_
nvgpu_mutex_init function in the driver.

20fcf813dd gpu: nvgpu: Use sw ops for BIOS
Some functions are not accessing hardware directly
but are being called using HAL ops: For example

.init = gv100_bios_init,
.preos_wait_for_halt = gv100_bios_preos_wait_for_halt,
.preos_reload_check = gv100_bios_preos_reload_check,
.devinit = gp106_bios_devinit,
.preos = gp106_bios_preos,
.verify_devinit = NULL,

This was being called as:
g->ops.bios.init(g)
g->ops.bios.preos_wait_for_halt(g)
g->ops.bios.preos_reload_check(g)
g->ops.bios.preos(g)
g->ops.bios.devinit(g)
g->ops.bios.verify_devinit(g)

Change the function access by using sw ops, like:
Create new function: nvgpu_bios_sw_init()
and based on hardware chip call the chip specific
bios sw init function: nvgpu_gv100_bios_sw_init()
and nvgpu_tu104_bios_sw_init()to assign the sw
ops

e9e9ae9b92 gpu: nvgpu: fix MISRA rule 14.2 for loops
MISRA Rule 14.2 requires for loop to be well-formed. A well-formed for
loop has below requirements:
1. first clause can be empty or should assign value to a single loop
counter
2. second clause should exist and use loop counter or loop control flag.
It should not use any variable modified in the loop body.
3. third cluase should only update loop counter and should not use
objects modified in the loop body.

This modifies for loops to process single loop counter. The patch moves
additional initializations before for loop, conditions at loop start
and variable updates at the end of for loop.

Description:
Present p-state unit handle both pstate boardobj and
initializing all the units. As part of restructuring,
the pstate unit is separated into two units:
1) Perf_pstate: This unit will handle pstate boardobjs.
2) Pmu_pstate: This unit will initialize all the units
which supoort performance states.

Changes:
1) Created pmu_pstate unit.
2) Pstate boardobjs are moved under perf_pstate which
is under perf unit.
