693305c0fd gpu: nvgpu: subcontext add/remove support
Subcontext PDBs and valid mask in the instance blocks of the channels
in various subcontexts has to be updated when new subcontext is
created or a subcontext is removed.

Replayable fault state is cached in the channel structure. Replayable
fault state for subcontext is set based on first channel's bind
parameter. It was earlier programmed in function channel_setup_ramfc.

init_inst_block_core is updated to setup TSG level pdb map and mask.

Added new hal gv11b_channel_bind to enable the subcontext on channel
bind.

5b55088970 gpu: nvgpu: skip subctx pdb init during as-channel bind
While creating a new channel, ioctls are called in the below sequence:
  1. GPU_IOCTL_OPEN_CHANNEL
  2. AS_IOCTL_BIND_CHANNEL
  3. TSG_IOCTL_BIND_CHANNEL_EX
  4. CHANNEL_ALLOC_GPFIFO_EX
  5. CHANNEL_ALLOC_OBJ_CTX.

subctx pdbs and valid mask are programmed in the channel instance block
in the channel ioctls AS_IOCTL_BIND_CHANNEL & CHANNEL_ALLOC_GPFIFO_EX.

Programming them in the ioctl AS_IOCTL_BIND_CHANNEL is redundant.
Remove related hal g->ops.mm.init_inst_block_for_subctxs.

The hal init_inst_block will program context pdb and big page size.
The hal init_inst_block_core will program context pdb, big page size
and subctx 0 pdb. This is used by h/w units (fecs, pmu, hwpm, bar1,
bar2, sec2, gsp, perfbuf etc.).

For user channels, subctx pdbs are programmed as part of ramfc setup.

1b1d183b9c gpu: nvgpu: simplify gmmu map calls
Introduce nvgpu_gmmu_map_partial() to map a specific size of a buffer
represented by nvgpu_mem, or what nvgpu_gmmu_map() used to do. Delete
the size parameter from nvgpu_gmmu_map() such that it now maps the
entire buffer. The separate size parameter is a historical artifact from
when nvgpu_mem did not exist yet; the typical use is to map the entire
buffer.

Mapping at a certain address with nvgpu_gmmu_map_fixed() still takes the
size parameter.

The returned address still has to be stored somewhere, typically to
mem.gpu_va by the caller so that the matching unmap variant finds the
right address.

4d3a935b1a gpu: nvgpu: enable lazy bootstrap support for NVRISCV pmu
Lazy bootstrap is a secure iGPU feature where LS falcons(FECS and
GPCCS) are bootstrapped by LSPMU in both cold boot and recovery boot.
As there is no ACR running after boot, we need LSPMU to bootstrap LS
falcons to support recovery.
In absence of LSPMU, ACR will bootstrap LS falcons but recovery is
not supported.
This CL will enable Low secure falcon manager(lsfm) to support
Lazy bootstrap feature. This will allow nvgpu to send cmds
to lspmu to bootstrap LS falcons.

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.

netlist unit. With these APIs, direct reference of netlist data
outside of netlist unit is avoided.

6f0455a1c7 gpu: nvgpu: use API to get hwpm_map size
Add new API nvgpu_gr_hwpm_map_get_size() in gr.hwpm_map unit to get
size of hwpm_map.
Use this API to get size and allocate each pm_ctx

Move nvgpu_gr_hwpm_map_init() call to gr.gr unit in gr_init_setup_sw()
instead of calling it from gr.falcon unit

Add nvgpu_gr_hwpm_map_init() to vGPU initialization to initialize
hwpm_map size on vGPU

12a06fe060 gpu: nvgpu: move ctxsw related data to gr falcon
Added new function to add require sw initionaltions. before enabling
gr hw. Added nvgpu_netlist_init_ctx_vars and nvgpu_gr_falcon_init_support
as part of this function:
int nvgpu_gr_prepare_sw(struct gk20a *g)

Moved following structure defs from gr_gk20a.h to gr_falcon.h and
renamed appropriately:
gk20a_ctxsw_ucode_segment -> nvgpu_ctxsw_ucode_segment
gk20a_ctxsw_ucode_segments -> nvgpu_ctxsw_ucode_segments

Moved following struct to gr_falcon_priv.h:
gk20a_ctxsw_ucode_info -> nvgpu_ctxsw_ucode_info

Moved following data from struct gk20a to new structure in gr_falcon_priv.h
struct nvgpu_gr_falcon:
struct nvgpu_mutex ctxsw_disable_lock;
int ctxsw_disable_count;
struct gk20a_ctxsw_ucode_info ctxsw_ucode_info;

Also moved following data from gr_gk20.h to struct nvgpu_gr_falcon:
struct nvgpu_mutex fecs_mutex;
bool skip_ucode_init;
wait_ucode_status
GR_IS_UCODE related enums
eUcodeHandshakeInit enums

Now add a pointer to this new data structure from struct gr_gk20a to
access gr_falcon related data and modified code to reflect this
change:
struct nvgpu_gr_falcon *falcon;

Added following functions to access gr_falcon data:
struct nvgpu_mutex *nvgpu_gr_falcon_get_fecs_mutex(
				struct nvgpu_gr_falcon *falcon);
struct nvgpu_ctxsw_ucode_segments *nvgpu_gr_falcon_get_fecs_ucode_segments(
				struct nvgpu_gr_falcon *falcon);
struct nvgpu_ctxsw_ucode_segments *nvgpu_gr_falcon_get_gpccs_ucode_segments(
				struct nvgpu_gr_falcon *falcon);
void *nvgpu_gr_falcon_get_surface_desc_cpu_va(
				struct nvgpu_gr_falcon *falcon);
