Subject: [PATCH FYI 0/4] FIQ-based backtracing support
Date: Fri, 5 Sep 2014 10:40:56 +0100 [thread overview]
Message-ID: <20140905094056.GD30401@n2100.arm.linux.org.uk> (raw)
This is a prototype series for FIQ backtracing support, which is most
useful when trying to debug things like a spinlock lockup on a SMP
system, or a deadlock inside an IRQs-off region.
Some of this is based upon work by Daniel Thompson and others.
This is a work in progress - especially the final patch.
