cc9f3d80e3 gpu: nvgpu: pass pid/tid from os specific code to common code
linux driver runs in user's process but qnx driver has dedicate driver
process, so they have different way to get user pid. nvgpu common code
expect calls from os specific code pass pid/tid.

ce/cde open channel for internal use, we use driver pid.

a0dfb2b911 gpu: nvgpu: gv100: consider floorswept FBPA for getting unicast list
In gr_gv11b/gk20a_create_priv_addr_table() we do not consider floorswept FBPAs
and just calculate the unicast list assuming all FBPAs are present
This generates incorrect list of unicast addresses

Fix this introducing new HAL ops.gr.split_fbpa_broadcast_addr
Set gr_gv100_get_active_fpba_mask() for GV100
Set gr_gk20a_split_fbpa_broadcast_addr() for rest of the chips

gr_gv100_get_active_fpba_mask() will first get active FPBA mask and generate
unicast list only for active FBPAs

d91ea322e1 gpu: nvgpu: fix gpc/tpc index for SMPC broadcast conversion
In gv11b_gr_egpc_etpc_priv_addr_table(), we call
gv11b_gr_update_priv_addr_table_smpc() to convert SMPC broadcast address into
list of unicast addresses

But before calling gv11b_gr_update_priv_addr_table_smpc() we sometimes
incorrectly set gpc_num/tpc_num to zero and that leads to generating incorrect
list of unicast addresses

Remove this incorrect initialization of gpc_num/tpc_num

Also update gv11b_gr_egpc_etpc_priv_addr_table() to receive tpc_num along with
gpc_num

This patch cleans that up by deleting the unnecessary os_linux.h

the gk20a struct. The platform data is copied to the gk20a struct
in the platform initialization code so that this common code can
access said data without requiring any knowledge of the OS platform

Handle this exception explicitly in this sequence -
- set error notifier first
- clear the interrupt
- return error from gr_gv11b_handle_warp_esr_error_misaligned_addr() so that
  RC recovery is triggered by gk20a_gr_isr()

Ensure that the error value is propagated back to gk20a_gr_isr() correctly

Use nvgpu_set_error_notifier_if_empty() to set error notifier since this will
prevent overwriting of error notifier value in case gk20a_gr_isr() also tries
to write to some error notifier value

code by deleting nvgpu_semaphore_release() and refactoring
__nvgpu_semaphore_release() to nvgpu_semaphore_reset() that only
"fast-forwards" the semaphore to a later value.

While doing this, the meaning of nvgpu_semaphore_incr() changes, so
rename it to nvgpu_semaphore_prepare(). Now it's only used to prepare an
nvgpu_semaphore for a value that the HW will increment the sema to.

Also change the BUG_ON that guards sema double-inits into just WARN_ON.

bac51e8081 gpu: nvgpu: allow syncfds as prefences on deterministic
Accept submits on deterministic channels even when the prefence is a
syncfd, but only if it has just one fence inside.

Because NVGPU_SUBMIT_GPFIFO_FLAGS_SYNC_FENCE is shared between pre- and
postfences, a postfence (SUBMIT_GPFIFO_FLAGS_FENCE_GET) is not allowed
at the same time though.

The sync framework is problematic for deterministic channels due to
certain allocations that are not controlled by nvgpu. However, that only
applies for postfences, yet we've disallowed FLAGS_SYNC_FENCE for
deterministic channels even when a postfence is not needed.

34323b5595 gpu: nvgpu: wait for all prefence semas on gpu
The pre-fence wait for semaphores in the submit path has supported a
fast path for fences that have only one underlying semaphore. The fast
path just inserts the wait on this sema to the pushbuffer directly. For
other fences, the path has been using a CPU wait indirection, signaling
another semaphore when we get the CPU-side callback.

Instead of only supporting prefences with one sema, unroll all the
individual semaphores and insert waits for each to a pushbuffer, like
we've already been doing with syncpoints. Now all sema-backed syncs get
the fast path. This simplifies the logic and makes it more explicit that
only foreign fences need the CPU wait.

There is no need to hold references to the sync fence or the semas
inside: this submitted job only needs the global read-only sema mapping
that is guaranteed to stay alive while the VM of this channel stays
alive, and the job does not outlive this channel.

- Added new volt load, set_voltage & get_voltage methods for gv10x
  using RPC & added code to handle ack in pmu_rpc_handler() along
  with struct rail_list changes.
- Updated volt ops of gp106 & gv100 to point to respective methods.
- Added member volt_dev_idx_ipc_vmin & volt_scale_exp_pwr_equ_idx to
  "struct nv_pmu_volt_volt_rail_boardobj_set" & "struct voltage_rail"
  made changes to update members as needed.
- Added member volt_scale_exp_pwr_equ_idx to
  "struct vbios_voltage_rail_table_1x_entry" to read
  value from VBIOS table & update rail boardobj set interface.
- Defines for volt RPC "NV_PMU_RPC_ID_VOLT_*"
- Define struct's volt load, set_voltage & get_voltage to execute
