Noticed while building a new kernel from latest git:
Debug Store support (X86_DS) [Y/n/?] (NEW) ?
and asking for help just gives
Add support for Debug Store.
This allows the kernel to provide a memory buffer to the hardware
to store various profiling and tracing events.
This doesn't really let me decide if I want it or not. Is there a cost
to enabling this, and if so what? What new feature does this give me?
Is there even a point to making this a user-visible option at all, or
should it just be an internal config variable selected by X86_PTRACE_BTS
and any future users of this?
X86_PTRACE_BTS also could use an improved help text.
No patch, sorry, since I don't actually know for sure what this does.
Thanks,
Roland
