b67a3cd053 gpu: nvgpu: ga10b: Correct VAB implementation
This patch performs the following improvements for VAB:
1) It avoids an infinite loop when collecting VAB information.
   Previously, nvgpu incorrectly assumed that the valid bit would
   be eventually set for the checker when polling. It may not be set
   if a VAB-related fault has occurred.
2) It handles the VAB_ERROR mmu fault which may be caused for various
   reasons: invalid vab buffer address, tracking in protected mode,
   etc. The recovery sequence is to set the vab buffer size to 0 and
   then to the original size. This clears the VAB_ERROR bit. After
   reseting, the old register values are again set in the recovery
   code sequence.
3) Use correct number of VAB buffers. There's only one VAB buffer on
   ga10b, not two.
4) Simplify logic.

632644b44a gpu: nvgpu: couple runlist domains and nvs
Now that the main nvsched code exists in the nvgpu build, make it
control the runlist domains. As a new nvs domain is created, create the
relevant runlist data too. To support the default domain, create a
default nvs domain at boot.

The scheduling domain code owns the responsibility of domain lifetime,
and runlist domains exist to serve that logic although the RL domains
are directly used by channel and TSG logic. Add refcounting to the
scheduler uapi level to make sure that busy domains (that still have TSG
participants) do not get removed too early.

Adjust error injection sensitive unit tests to match the updated logic.

9be8fb80a2 gpu: nvgpu: make tsgs domain aware
Start transitioning from an assumption of a single runlist buffer to the
domain based approach where a TSG is a participant of a scheduling
domain that then owns has a runlist buffer used for hardware scheduling.

Concretely, move the concept of a runlist domain up to the users of the
runlist code. Modifications to a runlist need to specify which domain is
modified.

There is still only the default domain that is created at boot.

1d23b8f13a gpu: nvgpu: introduce internal runlist domain
The current runlist code assumes a single runlist buffer to hold all TSG
and channel entries. Create separate RL domain and domain memory types
to hold data that is related to only a scheduling domain and not
directly to the runlist hardware; in the future, more than one domains
may exist and one of them is enabled at a time.

The domain is used only internally by the runlist code at this point and
is functionally equivalent to the current runlist memory that houses the
round robin entries.

The double buffering is still kept, although more domains might benefit
from some cleverness. Although any number of created domains may be
edited in runtime, nly one runlist memory is accessed by the hardware at
a time. To spare some contiguous memory, this should be considered an
opportunity for optimization in the future.

ed16377983 gpu: nvgpu: allocate comptags and store metadata in REGISTER_BUFFER ioctl
To enable userspace query about comptags allocation status of a buffer,
comptags are to be allocated only during buffer registration done by
nvrm_gpu. Earlier, they were allocated during map.

nvrm_gpu will be sending metadata blob to be associated with the buffer.
This will have to be stored in the dmabuf privdata for all the buffers
registered by nvrm_gpu.

This patch moves the privdata allocation to buffer registration ioctl.

Remove g->mm.priv_lock as it is not needed now. This lock was added
to protect dmabuf private data setup. That private data is now
handled through dmabuf->ops and setup of dmabuf->ops is done
under dmabuf->lock.

To support legacy userspace, this patch still allocates comptags on
demand on map calls for unregistered buffers.

f51a43b579 gpu: nvgpu: ga10b: fix fetching of FBP_L2 FS mask
On all chips except ga10b, the number of ROP, L2 units per FBP
were in sync, hence, their FS masks could be represented by a single
fuse register NV_FUSE_STATUS_OPT_ROP_L2_FBP. However, on ga10b, the ROP
unit was moved out from FBP to GPC and it no longer matches the number
of L2 units, so the previous fuse register was broken into two -
NV_FUSE_CTRL_OPT_LTC_FBP, NV_FUSE_CTRL_OPT_ROP_GPC.

At present, the driver reads the NV_FUSE_CTRL_OPT_ROP_GPC register
and reports incorrect L2 mask. Introduce HAL function
ga10b_fuse_status_opt_l2_fbp to fix this.

In addition, rename fields and functions to exclusively fetch L2 masks,
this should help accommadate ga10b and future chips in which L2 and ROP units
are not in same. As part of this, the following functions and
fields have been renamed.
- nvgpu_fbp_get_rop_l2_en_mask => nvgpu_fbp_get_l2_en_mask
- fuse.fuse_status_opt_rop_l2_fbp => fuse.fuse_status_opt_l2_fbp
- nvgpu_fbp.fbp_rop_l2_en_mask => nvgpu_fbp.fbp_l2_en_mask

The HAL ga10b_fuse_status_opt_rop_gpc is removed as rop mask is not
used anywhere in the driver nor exposed to userspace.

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.

Update the nvgpu_runlist_update_for_channel() function:

  - Rename it to nvgpu_runlist_update()
  - Have it take a pointer to the runlist to update instead
    of a runlist ID. For the most part this makes the code
    better but there's a few places where it's worse (for
    now).

This starts the slow and painful process of moving away from
the non-runlist code using runlist IDs in many places it should
not.

Most of this patch is just fixing compilation problems with
the minor header updates.

Also rename the fields runlist_info and active_runlist_info to
simply runlists and active_runlists respectively. Again the info
text is just not necessary and somewhat misleading. These structs
_are_ the runlist representations in SW; they are not merely
informational.

Also add an rl_dbg() macro to print debug info specific to
runlist management and some debug prints specifying the runlist
topology for the running chip.

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.

8b133e098e gpu: nvgpu: vgpu: always map gmmu kernel pages with 4kB page size
By always mapping gmmu kernel page using 4kB page, it'll be consistent
with native nvgpu driver. It's a workaround for enabling 64KB os kernel
page support.

In long term solution, GMMU_PAGE_SIZE_KERNEL will be os kernel page
size, and function nvgpu_gmmu_update_page_table will choose big page or
small page by comparing the size of GMMU_PAGE_SIZE_KERNEL with the size
of small or big pages. Regardingly vgpu will choose kernel page size by
comparing the size too when send map commands to server.

c36752fe3d gpu: nvgpu: sim: make ring buffer independent of PAGE_SIZE
The simulator ring buffer DMA interface supports buffers of the following sizes:
4, 8, 12 and 16K. At present, it is configured to 4K and it  happens to match
with the kernel PAGE_SIZE, which is used to wrap back the GET/PUT pointers once
4K is reached. However, this is not always true; for instance, take 64K pages.
Hence, replace PAGE_SIZE with SIM_BFR_SIZE.

Introduce macro NVGPU_CPU_PAGE_SIZE which aliases to PAGE_SIZE and replace
latter with former.

8cccb49bd2 gpu: nvgpu: collapse nvgpu_gr_prepare_sw into nvgpu_gr_alloc
common.gr unit exports a separate API nvgpu_gr_prepare_sw to
initialize some SW pieces required for nvgpu_gr_enable_hw().
A separate API is really unnecessary since same initialization
can be performed in nvgpu_gr_alloc().

Remove nvgpu_gr_prepare_sw() and HAL gops.gr.gr_prepare_sw().
Initialize falcon and interrupt structures in loop from
nvgpu_gr_alloc().

Move nvgpu_netlist_init_ctx_vars() from nvgpu_gr_prepare_sw() to
common init path since netlist parsing need not be done from
common.gr unit. It just needs to happen before nvgpu_gr_enable_hw().

Also, trigger nvgpu_gr_free() from gr_remove_support() instead
of OS specific paths. Also remove nvgpu_gr_free() calls from
probe error paths since nvgpu_gr_alloc is no longer called in
probe path.

Move interrupt and falcon data structure free calls to nvgpu_gr_free().

Also remove corresponding unit testing code that tests
nvgpu_gr_prepare_sw() specifically.
Update some unit tests to initialize ecc counters and netlist.
Disable some unit tests that fail for reasons unknown.
