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
to the regular UAPI header.

This patch adds kernel interface for dynamic TPC-PG feature.
User-space needs to send TPC-PG args to kernel via ioctl.
Dynamic TPC-PG feature will allow every context to specify the
number of TPC's it will use to run its workload.
This way, graphics driver can power off non-required TPC's
if a particular context has light to medium workload.

deterministic options on a per-channel basis. Currently, the only
supported option is to relax the no-railgating requirement on open

until the railgate option is reset.

Add max_css_buffer_size to gpu characteristics. In the virtual
case, the size of the cycle stats snapshot buffer is constrained
by the size of the mempool shared between the guest OS and the
RM server, so tools need to find out what is the maximum size
allowed.
In the native case, we return 0xffffffff to indicate
that the buffer size is unbounded (subject to memory availability),
in the virtual case we return the size of the mempool.
Also collapse native init_cyclestats functions to a single version,
as each chip had identical versions of the code.

In particular, in this mode, the userspace will tell the kernel
whether the kind is compressible, and if so, what is the
incompressible fallback kind. By supplying only the compressible kind,
the userspace can require that the map kind will not be demoted to the
incompressible fallback kind in case of comptag allocation failure.

NVGPU_GPU_FLAGS_SUPPORT_MAP_DIRECT_KIND_CTRL to signal whether direct
kind control is supported.

To support deterministic channels even with platforms where railgating
is supported, have each deterministic-marked channel hold a power
reference during their lifetime, and skip taking power refs for jobs in
submit path for those.
Previously, railgating blocked deterministic submits in general because
of gk20a_busy()/gk20a_idle() calls in submit path possibly taking time
and more significantly because the gpu may need turning on which takes a
nondeterministic and long amount of time.
As an exception, gk20a_do_idle() can still block deterministic submits
until gk20a_do_unidle() is called. Add a rwsem to guard this. VPR resize
needs do_idle, which conflicts with deterministic channels' requirement
to keep the GPU on. This is documented in the ioctl header now.
Make NVGPU_GPU_FLAGS_SUPPORT_DETERMINISTIC_SUBMIT_NO_JOBTRACKING always
set in the gpu characteristics now that it's supported. The only thing
left now blocking NVGPU_GPU_FLAGS_SUPPORT_DETERMINISTIC_SUBMIT_FULL is
the sync framework.
Make the channel debug dump show which channels are deterministic.

GPC2CLK has been replaced with GPCCLK on user API.
Remove related definition from kernel API.
GPCLCK and MCLK are currently assigned EQU values in kernel API.
We want to move to a simple enumeration as used in nvrm_gpu.
During the transition, an alias value will be defined for each
clock, and kernel will accept both.

Fields added to nvgpu_gpu_characteristics must be before the
/* Notes: .. */ section. Otherwise, there is a possibility that
cherry-picks for new fields actually go before "Notes" and that
breaks binary compatibility.

Internally we use GPC2CLK in the arbiter, but we should expose
GPCCLK on kernel API and in user space. Added GPCCLK on the ioctl
API. Arbiter uses GPC2CLK to make queries, then converts to GPCCLK.

Separate out new API gr_gp10b_set_ctxsw_preemption_mode()
which will check requested preemption modes and take appropriate
action for each preemption mode
This API will also do some sanity checking for valid
preemption modes and combinations
Define API set_preemption_mode() for gp10b which will set the
preemption modes passed as argument and then use
gr_gp10b_set_ctxsw_preemption_mode() and
update_ctxsw_preemption_mode() to update preemption mode
Legacy path from gr_gp10b_alloc_gr_ctx() will convert
flags NVGPU_ALLOC_OBJ_FLAGS_* into appropriate preemption modes
and then call gr_gp10b_set_ctxsw_preemption_mode()
New API set_preemption_mode() will use new flags
NVGPU_GRAPHICS/COMPUTE_PREEMPTION_MODE_* and set and update
ctxsw preemption mode
In gr_gp10b_update_ctxsw_preemption_mode(), update graphics
context to set CTA premption mode if mode
NVGPU_COMPUTE_PREEMPTION_MODE_CTA is set
Also, define preemption modes in nvgpu-t18x.h
and use them everywhere
Remove old definitions of modes from gr_gp10b.h
