5d06a59bc5 gpu: nvgpu: Cleanup uart and debugfs debug prints 
The gk20a_debug_dump() function implicitly adds a newline since it
uses nvgpu_err() under the hood (for uart destined prints). For the
seq_file destined writes it does not so there is an annoying inconsistency.

Remove the newline that many of the gk20a_debug_dump() calls add and add
the newline to the (now) seq_printf() call. This reduces the length of
debug dump logs and speeds them up - UART is _very_ slow after all.

Also cleanup some formatting issues in the various debug prints I
happened to notice.

it. Pass the vm to the queue constructor and have the channel code store
the queue to itself instead of poking at the channel from the queue
code. Adjust the cmdbuf queue api to take the queue, not the channel.

Move the inflight job fallback calculation to the channel code. The size
of the channel gpfifo isn't needed in the queue; just the job count is.

will be set in parse_mmu_fault_info hal so that

39844fb27c gpu: nvgpu: hide priv cmdbuf mem writes 
Add an API to append data to a priv cmdbuf entry. Hold the write pointer
offset internally in the entry instead of having the user keep track of
where those words are written to.

This helps in eventually hiding struct priv_cmd_entry from users and
provides a more consistent interface in general. The wait and incr
commands are now slightly easier to read as well when they're just
arrays of data.

A syncfd-backed prefence may be composed of several individual fences.
Some of those (or even a fence backed by just one) may be already
expired, and currently the syncfd export design releases and nulls
semaphores when expired (see gk20a_sync_pt_has_signaled()) so for those
the wait cmdbuf is appended with zeros; the specific function is for
this purpose.

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.

d0ffb335dc gpu: nvgpu: move nvgpu_has_syncpoints 
nvgpu_has_syncpoints is more general than a channel synchronization
related, so move it to nvhost.c from channel_sync.c. Move the
declaration from gk20a.h to nvhost.h.

As the debugfs knob is Linux related, move it from struct gk20a to
struct nvgpu_os_linux.

db9c1b1f97 gpu: nvgpu: don't build sw semas for dgpu 
Make tu104's sema cmd HAL ops depend on CONFIG_NVGPU_SW_SEMAPHORE
in addition to the kernel mode submit flag.

Drop CONFIG_NVGPU_SW_SEMAPHORE from NVGPU_FORCE_DGPU_SAFETY_PROFILE.
Semaphore-based synchronization is not actually needed for dgpu.
