Add below two new HALs
gops.fb.enable_hub_intr() to enable hub interrupts
gops.fb.disable_hub_intr() to disable hub interrupts
Set existing APIs gv11b_fb_enable/disable_hub_intr() to these HALs
Call the HALs everywhere instead of calling the APIs directly

Before passing in an unsigned value to abs() cast the result
of the subtraction to signed.
In Linux this happens automatically but on non-Linux platforms
abs() does not necessarily do this. clang flags this case as
a pointless operation: abs(x) obviously must equal x for any
unsigned x.
This change should hopefully preserve the Linux behavior but
avoid the compiler warning from clang.

The forced PRAMIN reads and writes for sysmem buffers haven't worked in
a while since the PRAMIN access code was refactored to work with
vidmem-only sgt allocs. This feature was only ever meant for testing and
debugging PRAMIN access and early dGPU support, but that is stable
enough now so just delete the broken feature instead of fixing it.

The mechanism of posting events to userspace is OS specific.
In linux this works through poll fd, wherein we can make use
of nvgpu_cond variables to poll and trigger the corresponding
wait_queue.
The post event functionality on QNX doesn't work on poll though.
It uses iofunc_notify_trigger to post the events to the calling
process. As such QNX can't work with nvgpu_cond's.
To overcome this issue, it is proposed to create OS specific
interface function for posting clk arb events. Linux can call
nvgpu_cond based implementation, which makes sense since these
are already initialized and poll'ed in Linux specific code only.
QNX can implement this interface to call iofunc_notify_*
functions, as per its need.

TLC buffer sizes and credit init values do not match with
the values recommended by IAS for dGPU-Xavier configuration.
These buffer configuration values affect the latency over link.

Add NVGPU_IOCTL_CHANNEL_RESCHEDULE_RUNLIST ioctl to reschedule runlist,
and optionally check host and FECS status to preempt pending load of
context not belonging to the calling channel on GR engine during context
switch.
This should be called immediately after a submit to decrease worst case
submit to start latency for high interleave channel.
There is less than 0.002% chance that the ioctl blocks up to couple
miliseconds due to race condition of FECS status changing while being read.
For GV11B it will always preempt pending load of unwanted context since
there is no chance that ioctl blocks due to race condition.
Also fix bug with host reschedule for multiple runlists which needs to
write both runlist registers.

This header doesn't have anything in it yet but the header is
now present. A change recently went in that only checked for
__KERNEL__ before falling back to including the QNX header.
This caused the POSIX build in GVS to attempt to include the
QNX header. The QNX src is not synced in userspace dev-kernel
tests builds resulting in a missing header.

For most of the builds we have in GVS userspace is 64 bits. But
it seems like at least some L4T userspace builds are either not
32 bits or have an UL that only covers 32 bits. This is seen in
GVS:

This patch simply bumps the UL to ULL in BIT() to make sure that
we always have at least 64 bits available for the BIT() macro.

Semaphore methods currently being used in Volta are deprecated for future chips
And on Volta we support both old and new methods
So replace old methods by new methods on Volta itself so that new methods
get tested on silicon
Implement below HALs for Volta with new semaphore methods
gops.fifo.add_sema_cmd() to insert HOST semaphore acquire/release methods
gops.fifo.get_sema_wait_cmd_size() to get size of acquire command buffer
gops.fifo.get_sema_incr_cmd_size() to get size of release command buffer
Also use new methods in these APIs
gv11b_fifo_add_syncpt_wait_cmd()
gv11b_fifo_add_syncpt_incr_cmd()
And change corresponding APIs to reflect correct size of command buffer
gv11b_fifo_get_syncpt_wait_cmd_size()
gv11b_fifo_get_syncpt_incr_cmd_size()

Currently gpu sysfs retrieves Fmax@Vmin by direct call into Tegra DVFS
driver that introduces compile time dependencies on CONFIG_TEGRA_DVFS.
In addition incorrect clock is used for DVFS information access.
Re-factored sysfs node to use generic GPU clock operation for Fmax@Vmin
read. This would fix a bug in target clock selection, and allows to
remove dependency of sysfs on CONFIG_TEGRA_DVFS.
Updated nvgpu_linux_get_fmax_at_vmin_safe operation itself so it can be
called on platforms that does not support Tegra DVFS, although 0 will
still be returned as Fmax@Vmin on such platforms.

Read GP_GET and GET from hardware every time when the poll timer expires
instead of when the watchdog timer expires. Restart the watchdog timer
if the get pointers have increased since the previous read. This way
stuck channels are detected quicker.
Previously it could have taken at most twice the watchdog timeout limit
for a stuck channel to get recovered; with this change, a coarse sliding
window is used. The polling period is still 100 ms.
The difference is illustrated in the following diagram:
time 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0
get a b b b b b b b b b b b b b b b b b b b b
prev - n n n n n n n n n A n n n n n n n n n S
next - A s s s s s s s s s S
"time" represents wall time in polling units; 0 is submit time. For
simplicity, watchdog timeout is ten units. "get" is the GP_GET that
advances a little from a and then gets stuck at b. "prev" is the
previous behaviour, "next" is after this patch. "A" is when the channel
is detected as advanced, and "S" when it's found stuck and recovered;
small "s" is when it's found stuck but when the time limit has not yet
expired and "n" is when the hw state is not read.
