de2d39a422 gpu: nvgpu: init: fix MISRA 21.2 violations
MISRA Rule 21.2 prohibits naming identifiers beginning with a double
underscore. This updates the function names __nvgpu_check_gpu_state()
and __gk20a_warn_on_no_regs() to comply.

efe34ec6d7 gpu: nvgpu: PMU init update
Modified PMU subunits init sequence as they required during PMU RTOS
initialize stage, function nvgpu_pmu_early_init() allocates space for
all its subunit & its default values for further usage during runtime,
and function nvgpu_pmu_init() performs setup for sub units & starts
PMU-RTOS boot.

Deinit of all sub units allocated space will handled as part of
remove_support stage & also, during init stage upon failure of
init/setup sequence.

5ec94e4a98 gpu: nvgpu: Use sw ops for PMU PG unit
Some functions are not accessing hardware directly
but are being called using HAL ops: For example

g->ops.pmu.pmu_elpg_statistics,
g->ops.pmu.pmu_pg_init_param,
g->ops.pmu.pmu_pg_supported_engines_list,
g->ops.pmu.pmu_pg_engines_feature_list,

g->ops.pmu.pmu_lpwr_enable_pg,
g->ops.pmu.pmu_lpwr_disable_pg,
g->ops.pmu.pmu_pg_param_post_init,
g->ops.pmu.save_zbc

Change the function access by using sw ops, like:
Create new functions:

int nvgpu_pmu_elpg_statistics(struct gk20a *g, u32 pg_engine_id,
		struct pmu_pg_stats_data *pg_stat_data);
void nvgpu_pmu_save_zbc(struct gk20a *g, u32 entries);
bool nvgpu_pmu_is_lpwr_feature_supported(struct gk20a *g,
			u32 feature_id);

b4590adae4 gpu: nvgpu: fix MISRA 11.2 and 16.x in nvgpu_mem
MISRA Rule 11.2 doesn't allow conversion to or from an incomplete type
pointer, as it may result incorrect point alignment and may further lead
to undefined behavior.

MISRA Rule 16.x requires all switch statements to be well-formed with
terminating break statement for every switch-clause.

This patch fixes 11.2 and 16.x violations in common.mm.nvgpu_mem.

c19d7e3911 gpu: nvgpu: Use sw ops for Perfmon
Some functions are not accessing hardware directly
but are being called using HAL ops: For example

.pmu_init_perfmon = nvgpu_pmu_init_perfmon_rpc,
.pmu_perfmon_start_sampling = nvgpu_pmu_perfmon_start_sampling_rpc,
.pmu_perfmon_stop_sampling = nvgpu_pmu_perfmon_stop_sampling_rpc,
.pmu_perfmon_get_samples_rpc = nvgpu_pmu_perfmon_get_samples_rpc,

These were being called by:
g->ops.pmu.pmu_init_perfmon,
g->ops.pmu.pmu_perfmon_start_sampling,
g->ops.pmu.pmu_perfmon_stop_sampling,
g->ops.pmu.pmu_perfmon_get_samples_rpc

Change the function access by using sw ops, like:
Create new functions:
int nvgpu_pmu_perfmon_init(struct gk20a *g,
	struct nvgpu_pmu *pmu, struct nvgpu_pmu_perfmon *perfmon);
int nvgpu_pmu_start_sampling_perfmon(struct gk20a *g,

int nvgpu_pmu_get_samples_rpc_perfmon(struct gk20a *g,
	struct nvgpu_pmu *pmu, struct nvgpu_pmu_perfmon *perfmon);

and based on hardware chip call the chip specific
perfmon sw init function: nvgpu_gv11b_perfmon_sw_init() and
nvgpu_gv100_perfmon_sw_init() and assign the sw ops for perfmon

6c2c4181ae gpu: nvgpu: Create hal.mm.mm for misc MM HALs
There are many miscellaneous HALs for various MM related functionality.
This patch aims to migrate all the remaining MM code from the <chip>/
mm_<chip>.[ch] files in HAL files under hal/.

Much of this is fairly straightforward copy/paste and updates to the
HAL init files.

The exception to that is the move of the left over gv11b MMU fault
handling code in mm_gv11b.c. Having both a hal/mm/mm/mm_gv11b.c and
a gv11b/mm_gv11b.c file causes tmake to choke so the gv11b/mm_gv11b.c
file was moved to gv11b/mmu_fault_gv11b.c. This will be cleaned up in
a subsequent patch.

gr_gk20a.ctx_vars struct right now stores sizes for golden_image, zcull,
pm_ctxsw, and gfxp_preemption_buffer.
but these sizes should be really owned by respective units and should
be assigned to units as soon as they are queried from FECS

Add new structure to nvgpu_gr_falcon to hold sizes that will be queried
from FECS
struct nvgpu_gr_falcon_query_sizes {
        u32 golden_image_size;
        u32 pm_ctxsw_image_size;
        u32 preempt_image_size;
        u32 zcull_image_size;
};

gr.falcon unit now queries sizes from FECS and fills this structure.
gr.falcon unit also exposes below APIs to query above sizes

u32 nvgpu_gr_falcon_get_golden_image_size(struct nvgpu_gr_falcon *falcon);
u32 nvgpu_gr_falcon_get_pm_ctxsw_image_size(struct nvgpu_gr_falcon *falcon);
u32 nvgpu_gr_falcon_get_preempt_image_size(struct nvgpu_gr_falcon *falcon);
u32 nvgpu_gr_falcon_get_zcull_image_size(struct nvgpu_gr_falcon *falcon);

gr.gr unit now calls into gr.falcon unit to initailize sizes, and then
uses above exposed APIs to set sizes into respective units

vGPU will too fill up struct nvgpu_gr_falcon_query_sizes with all the sizes
and then above APIs will be used to set sizes into respective units

All of above means size variables in gr_gk20a.ctx_vars struct are no more
being referred. Delete them.

int nvgpu_gr_enable_ctxsw(struct gk20a *g);
int nvgpu_gr_falcon_halt_pipe(struct gk20a *g); ->
		int nvgpu_gr_halt_pipe(struct gk20a *g);

HALs also moved accordingly and updated code to reflect this.

Also moved following data back to gr from gr_falcon:
struct nvgpu_mutex ctxsw_disable_mutex;
int ctxsw_disable_count;

24af0d3330 gpu: nvgpu: fix num of sm used for mem alloc
Instead of using GPC and TPC counts to allocate memory
to hold sm info, use nvgpu_gr_config_get_no_of_sm() to get
the actual number. This fixes memory issues (corruption and
segmentation fault) seem when nvgpu_gpu_ioctl_wait_for_pause
is used.
