To update hwpm, we currently disable/preempt only one

of a TSG
Hence, use proper APIs to disable/preempt/enable which
will internally handle channel/TSG case

bug 1764398
PGSequencer settings use index to writ to PSORDER register setting.
HW has implementation for 28 PSORDER (PSORDER0 - 27).
Every write will auto increment index and index will wrap around
after it reaches 27.
In PROD settings we are writing enable for 0 to 27 and
zero for 28 to 65. This overwrites enables written to 0 to 27.
Effectively those partitions are never power gated.

To support vidmem, implement a way to access buffers via the PRAMIN
window instead of just kernel-mapped sysmem buffers for iGPU as of now.
Depending on the buffer aperture, choose between the two access types in
the buffer memory accessor functions.
vmap()/vunmap() pairs are no-ops for buffers that can't be cpu-mapped.
Two uses of DMA_ATTR_READ_ONLY are removed in the ucode loading path to
support writing to them too via the indirection in addition to cpu.

When we run out of gpfifo space or private command buffer
space, we have error spew like below :
__gk20a_channel_syncpt_incr: not enough priv cmd buffer space
gk20a_submit_channel_gpfifo: fail
Dumping these prints to UART cause increase in submit
latencies
But on these failures, we return -ENOSPC to UMD and then
UMD retries the submit, hence it might be unnecessary to dump
these prints
Hence, remove the error prints of insufficient space
and use gk20a_dbg_fn() instead of gk20a_err() to print failure
in gk20a_submit_channel_gpfifo()

FECS trace are currently collected using periodic
polling every 16.66 ms. Whenever polling thread
finds some events from FECS, it generates a SOF
event with current PTIMER value. These events may
introduce out of order timestamps, and extra
processing would be required in driver to insert
them in the right order. This change removes
SOF event generation, as they is currently no use
case for them.

fecs_trace.disable() method kills polling thread
and waits until it completes. dev->lock must not
be held while calling this function, as polling
thread may attempt to acquire it, leading to a
deadlock. Also fixed potential deadlock in
ioctl to disable trace.

In virtualization case, VM server is the only one
allowed to write to ctxsw ring buffer. It will
also generate an event in case of engine reset.
Only generate a tracepoint on Guest OS side.

Generate a ctxsw channel reset when engine needs to be reset.
This event is generated by the driver, while other events are

Add support for hwpm broadcast registers (ltc and lts)
In gr_gk20a_find_priv_offset_in_buffer, replace "Unknown address type" error
with informational message: gr_gk20a_exec_ctx_ops calls
gk20a_get_ctx_buffer_offsets and if that fails,
calls gr_gk20a_get_pm_ctx_buffer_offsets; HWPM registers will fail the first
call, so an error or warning is overkill.

We were not using the engine_type field in device info, and the code
did not handle chained entries properly. The code assumed that first
entry is for graphics and second for CE, which is not always true.
Improve the code to go through all entries of device_info, and
preserve values across entries until we reach the last entry.
Only last entry triggers a write to fifo engine info.
There can also be multiple engines with same type, so accumulate
interrupts and reset ids from all of them.
As the code got fixed, now it reads the engine enum correctly from
hardware. We used to compare that against CE0, but we should compare
against CE2.
gk20a_fifo_reset_engine() uses wrong constants - it is passed a
internal numbering of engines, but it compares them against hardware
engine enum.

While binding a channel to debug session in dbg_bind_channel_gk20a(),
we unbind the channel if channel fd is ~0
But UMD has already moved to use separate IOCTL to unbind a channel
from debug session
Hence this code can be removed now
