86c0a696ed gpu: nvgpu: Fix build for Linux v5.18
Upstream commit 7938f4218168 ("dma-buf-map: Rename to iosys-map")
renames 'struct dma_buf_map' to 'struct iosys_map' and breaks building
the NVGPU driver with Linux v5.18-rc1. In the NVGPU driver there are
many places where 'dma_buf_map' is used and so to clean-up the code and
minimise the impact of this change, add a gk20a_dmabuf_vmap() and a
gk20a_dmabuf_vunmap() helper function. These new functions support all
kernel versions and eliminate a lot the KERNEL_VERSION ifdefs.

3651d1150d gpu: nvgpu: update kmdi interfaces
Patch udpates/fixes following issues.
- Updates nvgpu_dbg_gpu_get_mappings_entry.size to u64 to address >4G
limitations.
- Removes offset from original cpuva and unmaps only original mapped
address.
- Call nvgpu_vm_find_mapped_buf_range() in place of
nvgpu_vm_find_mapped_buf() to find the addresses which are not
page aligned.
- Update logic to parse the gpuva while trying to find gpu mappings so
that gpuva which are more than the mapped buffer base address can also
be considered.

c0f4723339 gpu: nvgpu: perbuf: update PMA buffer mapping
The PMA unit can only access GPU VAs within a 4GB window, hence both
the user allocated PMA buffer and the kernel allocated bytes available
buffer should lie in the same 4GB window. This is accomplished by
carving out and reserving a 4GB VA space in perbuf.vm and using fixed
GPU VAs to ensure that both buffers are bound within the same 4GB window.

In addition, update ALLOC_PMA_STREAM to use pma_buffer_offset,
pma_buffer_map_size fields correctly.

dd94573e55 gpu: nvgpu: Update KMDI mapping interface
Finding gpu va mapping inside a given range is a two step process where
in first step number of mapping are queried and at second step it
queries for all the continues mapping range for that given gpu va
range. Mapping interface should count and return number of mappings if
input count is 0 in place of failing it.
Patch make the change for this two step process and only returns count
at first step and in second step returns the continues memory ranges.

Patch also replaces nvgpu_zalloc with nvgpu_big_zalloc to handle bigger
size allocation.

791dc18666 gpu: nvgpu: bvec for struct nvgpu_tsg_sm_error_state fields
Add Setter and Getter methods for accessing tsg->sm_error_states.
Getter returns a constant pointer for struct nvgpu_tsg_sm_error_state.
This renders it unnecessary to add BVEC for above fields for the struct
in multiple locations. The current design ensures that only a constant
pointer is obtained from the owner unit i.e. FIFO.

The following new methods are added. Both unit tests and BVEC tests
are added for them as well.

9b66fca165 gpu: nvgpu: move .exec_regops to only execute regops
HAL .exec_regops used to first validate regops then execute it, now
moving it to only execute the regops.

- It helps B0CC on HV. On server side it does not track profiler object,
but regops validation uses the profiler, so moving validation to client
side.
- The change also remove ctx_buffer_offset checking in
validate_reg_op_offset. The offset already checked again whitelists
which have be verified when update whitelist. Also vgpu does not have
information of ctx and golden image.
- Added function nvgpu_regops_exec to cover both regops validation and
execution.

869735cda4 gpu: nvgpu: add dynamic allowlist support
Add gv11b and tu104 HALs to get allowed  HWPM resource register ranges,
offsets, and stride meta data.

Add new enum nvgpu_pm_resource_hwpm_register_type for HWPM register
type. Add new struct nvgpu_pm_resource_register_range_map to store all
the register ranges for HWPM resources. Add pointer of map in struct
nvgpu_profiler_object along with map entry count.

Add new API nvgpu_profiler_build_regops_allowlist() to build the regops
allowlist dynamically while binding the resources. Map entry count is
received with get_pm_resource_register_range_map_entry_count() and only
those resource ranges are added for which resource is reserved by
profiler object.

Add nvgpu_profiler_destroy_regops_allowlist() to destroy the allowlist
while unbinding the resources.

Add static functions allowlist_range_search() to search a register
offset in HWPM resource ranges. Add another static function
allowlist_offset_search() to search the offset in per-resource offset
list.

Add nvgpu_profiler_validate_regops_allowlist() that accepts an offset
value, checks if it is in allowed ranges using allowlist_range_search()
and then checks if offset is in allowlist using allowlist_offset_search().

Update gops.regops.exec_regops() to receive profiler object pointer as
a parameter.

Invoke nvgpu_profiler_validate_regops_allowlist() from
validate_reg_ops() if prof pointer is not-null. This will be true only
for new profiler stack and not legacy profilers.

In gr_exec_ctx_ops(), skip regops execution if offset is invalid.

Buffers are allocated and released along with the profiler object.

New API will implements this :
-  copy regops data in chunks of 4K from userspace
- store them in staging buffer
- convert the new regop struct into common regop struct and also
  copy the content into second staging buffer
- trigger gops.regops.exec_regops() with second staging buffer as
  operation pointer
- convert common regop struct back into new regop struct and copy
  back to userspace

Export bunch of helper functions from ioctl_dbg.h. e.g.
nvgpu_get_regops_op_values_common()

Update regop execution code to skip regop execution if regop status
is not valid. This is only possible when userspace requests for
CONTINUE_ON_ERROR mode.

Add more documentation to some of the fields in UAPI header.

Note that maximum atomic operations reported by new API are same
as legacy API and are incorrect. This will be fixed up in upcoming
patches.

6daa0636d1 gpu: nvgpu: rework regops execution API
Rework regops execution API to accomodate below updates for new
profiler design

- gops.regops.exec_regops() should accept TSG pointer instead of
  channel pointer.
- Remove individual boolean parameters and add one flag field.

Below new flags are added to this API :
NVGPU_REG_OP_FLAG_MODE_ALL_OR_NONE
NVGPU_REG_OP_FLAG_MODE_CONTINUE_ON_ERROR
NVGPU_REG_OP_FLAG_ALL_PASSED
NVGPU_REG_OP_FLAG_DIRECT_OPS

Update other APIs, e.g. gr_gk20a_exec_ctx_ops() and validate_reg_ops()
as per new API changes.

Add new API gk20a_is_tsg_ctx_resident() to check context residency
from TSG pointer.

Convert gr_gk20a_ctx_patch_smpc() to a HAL gops.gr.ctx_patch_smpc().
Set this HAL only for gm20b since it is not required for later chips.
Also, remove subcontext code from this function since gm20b does not
support subcontext.

Remove stale comment about missing vGPU support in exec_regops_gk20a()

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()

08308bc936 gpu: nvgpu: rework pm resource reservation system
Current PM resource reservation system is limited to HWPM resources
only. And reservation tracking is done using boolean variables.

New upcoming profiler support requires reservation for all the PM
resources like SMPC and PMA stream. Using boolean variables is
not scalable and confusing. Plus the variables have to be replicated
on gpu server in case of virtualization.

Remove flag tracking mechanism and use list based approach to track
all PM reservations. Also, current HALs are defined on debugger object.
Implement new HALs in new pm_reservation object since it is really an
independent functionality.

Add new source file common/profiler/pm_reservation.c which implements
functions to reserve/release resources and to check if any resource
is reserved or not.
Add common/vgpu/pm_reservation_vgpu.c for vGPU which simply forwards
the request to gpu server.

Define new HAL object gops.pm_reservation and assign above functions
to below respective HALs :
g->ops.pm_reservation.acquire()
g->ops.pm_reservation.release()
g->ops.pm_reservation.release_all_per_vmid()

Last HAL above is only used for gpu server cleanup of guest OS.

Add below new common profiler functions that act as APIs to reserve/
release resources for rest of the units in nvgpu.
nvgpu_profiler_pm_resource_reserve()
nvgpu_profiler_pm_resource_release()

Initialize the meta data required for reservtion system in
nvgpu_pm_reservation_init() and call it during nvgpu_finalize_poweron.
Clean up the meta data before releasing struct gk20a.

Delete below HALs :
g->ops.debugger.check_and_set_global_reservation()
g->ops.debugger.check_and_set_context_reservation()
g->ops.debugger.release_profiler_reservation()

reservation is acquired by some other channel in TSG.
But now since we keep track of TSG itself, this case becomes
redundant and can be removed.

7581601f80 gpu: nvgpu: gr_priv header cleanup
Remove gr_priv.h from outside gr files.
Add hal function in gr.init for get_no_of_sm. This helps
to avoid dereferencing gr in couple of files for g->gr->config and
avoid gr_priv.h include in those files.

Replace nvgpu_gr_config_get_no_of_sm call with
g->ops.gr.init.get_no_of_sm for files outside gr unit.

efbe371fd5 gpu: nvgpu: Create hal/mm/gmmu and move gk20a GMMU code
Make a hal/mm/gmmu sub-unit for the GMMU HAL code. Also move the
gk20a specific HAL code there. gp10b will happen in the next patch.

This change also updates all the GMMU related HAL usage, of which
there is quite a bit. Generally the only change is a .gmmu needs to
be inserted into the HAL path. Each HAL init was also updated.

a91535e3a3 gpu: nvgpu: avoid gr_falcon dependency outside gr
Basic units like fifo, rc are having dependency on
gr_falcon. Avoided outside gr units dependency on gr_falcon
by moving following functions to gr:

int nvgpu_gr_falcon_disable_ctxsw(struct gk20a *g,
			struct nvgpu_gr_falcon *falcon); ->
int nvgpu_gr_disable_ctxsw(struct gk20a *g);

int nvgpu_gr_falcon_enable_ctxsw(struct gk20a *g,
			struct nvgpu_gr_falcon *falcon); ->
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;

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);
