Cover letter [PATCH V5 0/3] Add osnoise/options options
After adding the osnoise/options file, a set of on/off options came to my mind, most based on discussions while debugging problems with Juri and Clark.
The PANIC_ON_STOP option facilitates the vmcore generation to aid in the latency analysis using a crash dump.
The OSNOISE_PREEMPT_DISABLE and OSNOISE_IRQ_DISABLE options refine the type of noise that the osnoise tracer detects, allowing the tool to measure only IRQ-related noise, or NMI/HW-related noise, respectively.
Each patch has a description of the options and the last patch documents them in the osnoise documentation file.
