There have been various issues and limitations with the way perf uses
(task) contexts to track events. Most notable is the single hardware
PMU task context, which has resulted in a number of yucky things (both
proposed and merged).
Notably:
- HW breakpoint PMU
- ARM
At a previous time, we have successfully created a virtual sound card
based on rpmsg. The sound card works under this mechanism Cortex-A core
tells the Cortex-M core the format, rate, channel, .etc configuration
of the PCM parameters and Cortex-M controls real hardware devices such
as SAI and DMA.

Part of machine check error handling is done in realmode,
As of now instrumentation is not possible for any code that
runs in realmode.
When MCE is injected on KASAN enabled kernel, crash is
observed, Hence force inline or mark no instrumentation
for functions which can run in realmode to avoid

Architectures can select HAVE_NOP_MCOUNT if they choose
to nop out mcount call sites. If that config option is
selected, then --mnop is passed as an option to objtool,
along with --mcount.
Also, make sure that --mnop can be passed as an option
to objtool only when --mcount is passed.
