9d0d16cffd nvgpu: add insturmentation for ctxsw error codes
For integration testing in safety build, we need to test ctxsw firmware
error codes. inorder to test this, we need some instrumentation in
nvgpu driver.

Added below instrumentation for CTXSW FW error code integration testing.

 1. Reduce the ctxsw watchdog time, so ctxsw watchdog always triggered.
    Use CONFIG_NVGPU_CTXSW_FW_ERROR_WDT_TESTING for testing watchdog

 2. Submit unsupported method to CTXSW FW, it will trigger err.
    Use CONFIG_NVGPU_CTXSW_FW_ERROR_CODE_TESTING for testing err code.

bbb63c0a8c gpu: nvgpu: remove "trace/events/gk20a.h" from QNX build
- "include/trace/events/gk20a.h" file was having GPL2 license
(which should not used for QNX code). This file was used for
compiling linux userspace driver("libnvgpu-drv.so") and was used for
unit testing on QNX.
- This patch removes stubs in "include/trace/events/gk20a.h" file.
(which were used for linux userspace driver.)
- For QNX driver, "nvgpu_rmos/trace/events/gk20a.h" was used.
This patch moves that file to "include/nvgpu/posix/trace_gk20a.h" and
does relevant license change. This same file will be used for linux
userspace driver.
- This patch also creates a new file "include/nvgpu/trace.h" which
selects proper trace file depending on the config.

21f8b366cd gpu: nvgpu: fix misra 2.5 violations
MISRA Advisory Rule 2.5 states that a project should not contain unused
macro declarations.

While most of the violations in the nvgpu driver are due to unused
macros from hw headers, devinit-related headers, etc. there is a small
number that are due to things like:

 * macros not being used when they could/should be
 * macros in C files that are really not referenced
 * CPP build flag mismatches

This change eliminates such violations from the following:

 * replace constants with existing macros in timeout conversion code
 * wrap nvgpu_gmmu_dbg macro #defines in #ifdef CONFIG_NVGPU_TRACE/#endif
 * wrap MAX_MC_INTR_REGS #define in #ifdef CONFIG_NVGPU_NON_FUSA/#endif
 * remove unused FECS_MAILBOX_0_ACK_RESTORE from runlist code
 * wrap BACKTRACE_MAXSIZE macro with #ifndef _QNX_SOURCE/#endif

Xavier Chip Product POR was updated to 20G only. No more qual work

a single speed left, remove the code added to support nvlink speed from
VBIOS as it is redundant.

In order to get coverage numbers corresponding to the release build
let us remove the overriding of the build profile for safety qnx
build. This also needs that these components are built only for
safety qnx and l4t builds.

For x86 and L4T userspace build, default profile is still set to

d34bad0a27 nvgpu: gpu: simplify waiting logic for interrupt handler
The atomic counter in interrupt handler can overflow and result in
calling of BUG() which will crash the process. The equivalent
functionality can be implemented with just setting an atomic variable at
start of handler and resetting at end of handler. The wait can be longer
in case there is constant interrupts coming but ultimately it will end.
Generally the wait path is not time critical so it should not be an
issue. Also, fix the unit tests for mc.

e0a6000456 gpu: nvgpu: update SW quiesce
Update SW quiesce as follows:
- After waking up sw_quiesce_thread, nvgpu_sw_quiesce
  masks interrupts, then disables and preempts runlists
  without lock. There could be still a concurrent thread
  that would re-enable the runlist by accident. This is
  very unlikely and would mean we are not in mission mode
  anyway.
- In sw_quiesce_thread, wait NVGPU_SW_QUIESCE_TIMEOUT_MS,
  to leave some time for interrupt handler to set error
  notifier (in case of HW error interrupt). Then disable
  and preempt runlists, and set error notifier for remaining
  channels before exiting the process.

Also modified nvgpu_can_busy to return false in case
SW quiesce is pending. This will make subsequent
devctl to fail.
