[RFC PATCH 00/21] RAS daemon prototype, v1
From: Borislav Petkov <borislav.petkov(a)amd.com> (resubmitting since lkml wasn't on CC list) Hi guys, here's the first rough version of all the jerky code that attempts to implement a RAS daemon listening for MCEs using perf. This is a preview code only, I still need to figure out how to do the sample parsing... 1 Jul 2010 12:12

[RFC PATCH 2/6] perf: Generalize callchain_store()
callchain_store() is the same on every archs, inline it in perf_event.h and rename it to perf_callchain_store() to avoid any collision. This removes repetitive code.

[RFC PATCH 5/6] perf: Fix race in callchains
Now that software events don't have interrupt disabled anymore in the event path, callchains can nest on any context. So seperating nmi and others contexts in two buffers has become racy. Fix this by providing one buffer per nesting level. Given the size of the callchain entries (2040 bytes * 4), we now need to a... 1 Jul 2010 12:12
