With recent rework in nvgpu most of the <uapi/linux/nvgpu.h> includes
are not needed so remove them
Remove use of NVGPU_DBG_GPU_REG_OP_* in gk20a/gr_gk20a.c and use common
definition instead
Remove use of NVGPU_ALLOC_GPFIFO_FLAGS_REPLAYABLE_FAULTS_ENABLE in
gp10b/fifo_gp10b.c by defining new common flag
NVGPU_GPFIFO_FLAGS_REPLAYABLE_FAULTS_ENABLE and then parsing it in API
nvgpu_gpfifo_user_flags_to_common_flags()

We use dma_buf pointer cyclestate_buffer_handler in common code
But since this is linux specific, we need to move this out of common code and
into linux specific code
Move dma_buf pointer cyclestate_buffer_handler from common channel code to
struct nvgpu_channel_linux
Fix all pointer accesses to this handle
Move gk20a_channel_free_cycle_stats_buffer() to ioctl_channel.c since it is
mostly linux specific
And since gk20a_channel_free_cycle_stats_buffer() needs to be called while
closing the channel, call it from nvgpu_channel_close_linux()

We right now store dmabuf fd and dma_buf pointer for gk20a_cs_snapshot_client
But since dma_buf and all related APIs are linux specific, we need to remove
them from common code and move them to linux specific code
Add new linux specific structure gk20a_cs_snapshot_client_linux which includes
struct gk20a_cs_snapshot_client and linux specific dma_buf pointer
In gk20a_attach_cycle_stats_snapshot(), we first handle all dma_buf related
operations and then call gr_gk20a_css_attach()
Move gk20a_channel_free_cycle_stats_snapshot() to ioctl_channel.c
In gk20a_channel_free_cycle_stats_snapshot(), we call gr_gk20a_css_detach()
and then free up dma_buf in linux specific code
We also need to call gk20a_channel_free_cycle_stats_snapshot() while closing
the channel, so call it from linux specific nvgpu_channel_close_linux()

Context TSG teardown procedure:
1. Disable scheduling for the engine's runlist via PFIFO_SCHED_DISABLE.
This enables SW to determine whether a context has hung later in the
process: otherwise, ongoing work on the runlist may keep ENG_STATUS from
reaching a steady state.
2. Disable all channels in the TSG being torn down or submit a new runlist
that does not contain the TSG. This is to prevent the TSG from being
rescheduled once scheduling is reenabled in step 6.
3.
a)Initiate a preempt of the TSG by writing NV_PFIFO_PREEMPT
with the TSG's ID and the TYPE set to TSG if TSG id is known else
do 3b
b)Initiate a preempt of the engine by writing the bit associated with its
runlist to NV_PFIFO_RUNLIST_PREEMPT. This allows us to begin the preempt
process prior to doing the slow register reads needed to determine
whether the context has hit any interrupts or is hung. Do not poll
NV_PFIFO_RUNLIST_PREEMPT for the preempt to complete.
4. Check for preempt done
5. If a reset is needed as determined by step 4:
a. Halt the memory interface for the engine (as per the relevant engine
procedure).
b. Reset the engine via PMC_ENABLE.
c. Take the engine out of reset and reinit the engine (as per the relevant
engine procedure)
6. Re-enable scheduling for the engine's runlist via PFIFO_SCHED_ENABLE.

All the linux specific error_notifier codes are defined in linux specific
header file <uapi/linux/nvgpu.h> and used in all the common driver
But since they are defined in linux specific file, we need to move all the
uses of those error_notifiers in linux specific code only
Hence define new error_notifiers in include/nvgpu/error_notifier.h and
use them in the common code
Add new API nvgpu_error_notifier_to_channel_notifier() to convert common
error_notifier of the form NVGPU_ERR_NOTIFIER_* to linux specific error
notifier of the form NVGPU_CHANNEL_*
Any future additions to error notifiers requires update to both the form
of error notifiers
Move all error notifier related metadata from channel_gk20a (common code)
to linux specific structure nvgpu_channel_linux
Update all accesses to this data from new structure instead of channel_gk20a
Move and rename below APIs to linux specific file and declare them
in error_notifier.h
nvgpu_set_error_notifier_locked()
nvgpu_set_error_notifier()
nvgpu_is_error_notifier_set()
Add below new API and use it in fifo_vgpu.c
nvgpu_set_error_notifier_if_empty()
Include <nvgpu/error_notifier.h> wherever new error_notifier codes are used

This patch removes the dependency on the header file "uapi/linux/nvgpu.h"
for regops_gk20a.c. The original structure and definitions in the
uapi/linux/nvgpu.h is maintained for userspace libnvrm_gpu.h. The
following changes are made in this patch.
1) Defined common versions of the NVGPU_DBG_GPU_REG_OP* definitions inside
regops_gk20a.h.
2) Defined common version of struct nvgpu_dbg_gpu_reg_op inside
regops_gk20a.h naming it struct nvgpu_dbg_reg_op.
3) Constructed APIs to convert the NVGPU_DBG_GPU_REG_OP* definitions from
linux versions to common and vice versa.
4) Constructed APIs to convert from struct nvgpu_dbg_gpu_reg_op to
struct nvgpu_dbg_reg_op and vice versa.
5) The ioctl handler nvgpu_ioctl_channel_reg_ops first copies from
userspace into a local storage based on struct nvgpu_dbg_gpu_reg_op which
is copied into the struct nvgpu_dbg_reg_op using the APIs above and
after executing the regops handler passes the data back into userspace
by copying back data from struct nvgpu_dbg_reg_op to struct
nvgpu_dbg_gpu_reg_opi.

Move the implementation for channel job update callbacks that is based

This requires a bit of extra work for allocating OS-specific priv data

used more when more OS-specific features are moved.

Add a translation layer to convert from the NVGPU_AS_* flags to
to new set of NVGPU_VM_MAP_* and NVGPU_VM_AREA_ALLOC_* flags.
This allows the common MM code to not depend on the UAPI header
defined for Linux.
In addition to this change a couple of other small changes were
made:
1. Deprecate, print a warning, and ignore usage of the
NVGPU_AS_MAP_BUFFER_FLAGS_MAPPABLE_COMPBITS flag.
2. Move the t19x IO coherence flag from the t19x UAPI header

Most of VGPU code is linux specific but lies in common code
So until VGPU code is properly abstracted and made os-independent,
move all of VGPU code to linux specific directory
Handle corresponding Makefile changes
Update all #includes to reflect new paths
Add GPL license to newly added linux files

Commit 81868a187fa3b217368206f17b19309846e8e7fb updated barrier
usage to use the nvgpu wrappers and in doing so downgraded many
plain barriers {mb(), wmb(), rmb()} to the SMP versions of these
barriers.
The SMP version of the barriers in question are only issued
when running on an SMP machine. In most of the cases mentioned
above this is fine since the barriers are present to faciliate
proper ordering across CPUs. A single CPU is always coherent
with itself, so on a non-SMP case we don't need those barriers.
However, there are a few places where the barriers in use (GMMU
page table programming, IO accessors, userd) where the barrier
usage is for communicating and establishing ordering for the
GPU. We need these barriers for both SMP machines and non-SMP
machines. Therefor we must use the plain barrier versions.

For gp10b and previous chips, RM server will issue fake mmu fault to
reset the channel. And the mmu fault event will be sent to vgpu client,
which will cause the client to abort the channel or tsg.
But on gv11b, RM server doesn't issue fake mmu fault any more. So I need
to abort it right after the force reset is finished.

Check for interrupts or hangs while waiting for the preempt to complete.
During pbdma/eng preempt done polling, any stalling interrupts relating
to the runlist must be detected and handled in order for the preemption
to complete.
When PBDMA fault or CE fault occurs, the PBDMA will save out
automatically. TSG related to the context in which the fault occurred
will not be scheduled again until the fault is handled.
In the case of some other issue requiring the engine to be reset, TSG
will need to be manually preempted.
In all cases, a PBDMA interrupt may occur prior to the PBDMA being able to
switch out. SW must handle these interrupts according to the relevant handling
procedure before the PBDMA preempt can complete.
Opt for eng reset instead of waiting for preemption to be finished when
there is any stall interrupt pending during engine context preempt completion.
