d020778c55 gpu: nvgpu: reserve pma stream for legacy profiler
Legacy profiler does not reserve PMA stream resource with PM
reservation system. Also, HWPM system reset is separately implemented
in membuf disable path. And it does not even restore perf unit SLCG
prod values.

Allcoate a dummy profiler object for debug session in perfbuf map
path. Free it in perfbuf unmap path.

This has advantage of synchronizing PMA stream reservation with new
profiler stack. And this also leverages HWPM system reset and SLCG
handling code during resource reservation.

Remove explicit HWPM reset from gops.perf.membuf_reset_streaming()
HALs

dfd9feace6 gpu: nvgpu: recover pbdma errors before ack
When a pbdma fault needs a channel teardown, do the recovery/teardown
process before acking the pbdma interrupt status back. Acking it causes
the hardware to proceed which could release fences too early before the
involved channel(s) have been found to be broken.

With these host copyengine interrupts, the teardown sequence is light
and proceeds even with the pbdma intr flag still set; there are no
engines to reset when these pbdma launch check interrupts happen. The
bad tsg is just disabled and the channels in it aborted.

A few unit tests are so heavily affected by this refactor that they
would need to be rewritten. They're not strictly needed at the moment,
so do only half of the rewrite: just delete them.

fba96fdc09 gpu: nvgpu: Replace nvgpu_engine_info with nvgpu_device
Delete the struct nvgpu_engine_info as it's essentially identical to
struct nvgpu_device. Duplicating data structures is not ideal as it's
terribly confusing what does what.

Update all uses of nvgpu_engine_info to use struct nvgpu_device. This
is often a fairly straight forward replacement. Couple of places though
where things got interesting:

  - The enum_type that engine_info uses is defined in engines.h and
    has a bit of SW abstraction - in particular the GRCE type. The only
    place this seemed to be actually relevant (the IOCTL providing device
    info to userspace) the GRCE engines can be worked out by comparing
    runlist ID.
  - Addition of masks based on intr_id and reset_id; those can be
    computed easily enough using BIT32() but this is an area that
    could be improved on.

This reaches into a lot of extraneous code that traverses the fifo
active engines list and dramtically simplifies this. Now, instead of
having to go through a table of engine IDs that point to the list of
all host engines, the active engine list is just a list of pointers to
valid engines. It's now trivial to do a for-all-active-engines type
loop. This could even be turned into a generic macro or otherwise
abstracted in the future.

2012a6b558 gpu: nvgpu: add profiler api to execute regops
Implement new API nvgpu_prof_ioctl_exec_reg_ops() to support regops on
new profiler objects.

Add two new staging buffers to hold regops copied from userspace, and
to convert and execute regops in common code.
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.

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()

969b901999 gpu: nvgpu: create device/context profiler dev nodes
Create new dev nodes for device and context profilers. Example of dev
nodes on iGPU
/dev/nvhost-prof-dev-gpu - device scope profiler
/dev/nvhost-prof-ctx-gpu - context scope profiler

Add below APIs to open/close above dev nodes :
nvgpu_prof_dev_fops_open()
nvgpu_prof_ctx_fops_open()
nvgpu_prof_fops_release()

Add common API nvgpu_prof_fops_ioctl() to handle IOCTL call on these
dev nodes. Add IOCTL NVGPU_PROFILER_IOCTL_BIND_CONTEXT to bind the TSG
to profiler objects.

Add nvgpu_tsg_get_from_file() to retrieve TSG struct pointer from
file descriptor. Also store profiler object pointer into TSG struct.

Enable NVGPU_SUPPORT_PROFILER_V2_DEVICE capability on gv11b and tu104.
Note that this is not yet enabled for vGPU.
Keep NVGPU_SUPPORT_PROFILER_V2_CONTEXT capabiity disabled since this
will take longer to support.

Add new IOCTL NVGPU_PROFILER_IOCTL_UNBIND_CONTEXT so that userspace can
explicitly unbind the context and release the resources before closing
the profiler descriptor.

Add context_init flag to profiler object for book keeping.

ab2b0b5949 gpu: nvgpu: Set unserviceable flag early during RC
During recovery, we set ch->unserviceable at the end after we preempt
the TSG and reset the engines. It might be too late and user-space
might submit more work to the broken channel which is not desirable.
Move setting this unserviceable flag right at the start
of recovery sequence.
Another thread doing a submit can still read the unserviceable flag
just before it is set here, leaving that submit stuck if recovery
completes before the submit thread advances enough to set up a post
fence visible for other threads. This could be fixed with a big lock
or with a double check at the end of the submit code after the job
data has been made visible.
We still release the fences, semaphore and error notifier wait queues
at the end; so user-space would not trigger channel unbind while
channel is being recovered.

Also, change the handle_mmu_fault APIs to return void as the
debug_dump return value is not used in any of the caller APIs.

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()

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

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()

20235407ff gpu: nvgpu: Remove an old gm20b CE init hack
Remove an ancient piece of code that morphed from a hard coded fault ID
lookup in the original gk20a driver. In the old days there was no top
parsing code, so converting between engine ID and fault ID was done
by a simle function.

This code derived from that function for some reason. However, given
that the HW top table is not actually broken, this code never executes.
The only way this code would execute is if the HW top table reported
that the fault ID for a GRCE engine is 0. But this never happens.

0a0ce8212a gpu: nvgpu: use CIRC_GEQ for gv11b sema cmp
Do the internal job synchronization semaphore and syncpt shim
comparisons with ACQ_CIRC_GEQ instead of ACQ_STRICT_GEQ. The semas and
syncpts naturally wrap, and this matches the ACQ_GEQ of pre-gv11b chips
that the driver assumes.

With the strict comparison that does not use wraparound, waits for
semas/syncpts that have just wrapped back to zero would hang because a
small value is not strictly greater than equal to a value near U32_MAX.

fbb6a5bc1c gpu: nvgpu: Remove fifo->pbdma_map
The FIFO pbdma map is an array of bit maps that link PBDMAs to runlists.
This array allows other software to query what PBDMA(s) serves a given
runlist. The PBDMA map is read verbatim from an array of host registers.
These registers are stored in a kmalloc()'ed array.

This causes a problem for the device management code. The device
management initialization executes well before the rest of the FIFO
PBDMA initialization occurs. Thus, if the device management code
queries the PBDMA mapping for a given device/runlist, the mapping has
yet to be populated.

In the next patches in this series the engine management code is subsumed
into the device management code. In other words the device struct is
reused by the engine management and all host SW does is pull pointers to
the host managed devices from the device manager. This means that all
engine initialization that used to be done on top of the device
management needs to move to the device code.

So, long story short, the PBDMA map needs to be read from the registers
directly, instead of an array that gets allocated long after the device
code has run.

This patch removes the pbdma map array, deletes two HALs that managed
that, and instead provides a new HAL to query this map directly from
the registers so that the device code can use it.
