3c97f3b932 gpu: nvgpu: disallow binding more channels than MAX channels supported per TSG
There is HW specific limit on number of channel entries that can be
added for each TSG entry in runlist. Right now there is no checking
to enforce this from SW and hence if User binds more than supported
channels to same TSG, invalid TSG formation error interrupts are
generated.

Fix this by adding appropriate checks in below steps :

- Add new field ch_count to struct nvgpu_tsg to keep track of
  channels bound to TSG.
- Define new hal gops.runlist.get_max_channels_per_tsg() to retrieve
  HW specific maximum channel count per TSG.
- Implement the HAL for gk20a and gv11b chips, and assign new HALs for
  all chips appropriately.
- Increment ch_count while binding the channel to TSG and decrement it
  while unbinding.
- While binding channel to TSG, Check if current channel count is
  already equal to max channel count. If yes, print an error and bail
  out.

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.

Then clk arbitor will be rewritten for GA100 and enabled back.
This patch implements by adding a new flag NVGPU_CLK_ARB_ENABLED which

77c0b9ffdc gpu: nvgpu: Update runlist_update() to take runlist ptr
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.

gr_gv100_init_hwpm_pmm_register() and gr_gv100_set_pmm_register() right
now assume common chiplet stride for all sys/fbp/gpc and use common API

Chiplet strides are same for all partitions only by chance, and future
chip might change that.

Hence add and use below 3 separate HALs to get appropriate strides.
g->ops.perf.get_pmmsys_per_chiplet_offset()
g->ops.perf.get_pmmgpc_per_chiplet_offset()
g->ops.perf.get_pmmfbp_per_chiplet_offset()

Also store sys/fbp/gpc perfmon count in struct gk20a after first query
instead of querying them again and again. Querying the counts from HW

Move nvgpu_netlist_init_ctx_vars() from nvgpu_gr_prepare_sw() to

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().

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 :

359fc24aaf gpu: nvgpu: Rework engine management to work with vGPU
Currently the vGPU engine management rewrites a lot of the common
device agnostic engine management code.

With the new top HAL parsing one device at a time, it is now more
easily possible to tie the vGPU into the new common device framework
by implementing the top HAL but with the vGPU engine list backend.

This lets the vGPU inherit all the common engine and device
management code. By doing so the vGPU HAL need only implement a
trivial and simple HAL.

This also gets us a step closer to merging all of the CE init
code: logically it just iterates through all CE engines whatever
they may be. The only reason this differs between chips is because
of the swap from CE0-2 to LCEs in the Pascal generation. This could
be abstracted by the unit code easily enough.

Also, the pbdma_id for each engine has to be added to the device
struct. Eventually this was going to happen anyway, since the
device struct will soon replace the nvgpu_engine_info struct.
It's a little bit of an abuse but might be worth it long term. If
not, it should not be difficult to replace uses of dev->pbdma_id
with a proper lookup of PBDMA ID based on the device info.

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()

1ff79b1d2c gpu: nvgpu: remove support for quad reg_op
quad type reg_ops were only needed on Kepler, and not for any other chip
beginning Maxweel.

HAL g->ops.gr.access_smpc_reg() was incorrectly set for Volta and Turing
whereas it was only applicable to Kepler. Delete it.

There is no register in the quad type whitelist since the type itself is
not supported anymore. Remove the empty whitelists for all chips and
also delete below HALs:
g->ops.regops.get_qctl_whitelist()
g->ops.regops.get_qctl_whitelist_count()

hal/regops/regops_gv100.* files are not used anymore. Delete the files
instead of just deleting quad HALs in these files.

Remove the get_mask_on_id() HAL and replace it's usage with the
global nvgpu_engine_get_mask_on_id() function. There's no need
to have this function as a HAL.

Make the syncpt and sema wait and incr command HAL ops consistent. Add
CONFIG_NVGPU_SW_SEMAPHORE guards for the semaphore ops. The syncpoint
ops already have CONFIG_TEGRA_GK20A_NVHOST around them.

Delete the dummy syncpt ops. They are not used; the ops are only needed
when the real versions exist.

6202ead057 gpu: nvgpu: split sema sync hal to wait and incr
Instead of one HAL op with a boolean flag to decide whether to do one
thing or another entirely different thing, use two separate HAL ops for
filling priv cmd bufs with semaphore wait and semaphore increment
commands. It's already two ops for syncpoints, and explicit commands are
more readable than boolean flags.

Change offset into cmdbuf in sem wait HAL to be relative to the cmdbuf,
so the HAL adds the cmdbuf internal offset to it.

While at it, modify the syncpoint cmdbuf HAL ops' prototypes to be
consistent.
