Subject: Function Profiler broken on today's linux-next
Date: Wed, 16 Jul 2014 11:23:28 -0500 [thread overview]
Message-ID: <20140716162328.GJ1365@saruman.home> (raw)
Hi folks,
I was trying to use Kernel Function Profiler to figure out why my
driver's IRQ handler is taking so much CPU time but to my surprise,
whenever I try to trace anything, I get a "Unable to handle kernel
paging request at virtual address XXXX" error.
Is anybody else seen that or did I screw up my Kernel config ?
cheers
ps: I have tried tracing a few different drivers and they all trigger
the same problem.
