debug registers, write breakpoints, and x86
Hi, I'm running 2.6.27 on x86 (64-bit) and I have what appears to be a memory trampler. I'd like to use a write breakpoint on the address being trampled to see who's doing it. From what I understand, I'll need to set one of DR0-3 (let's use DR3) to my address of interest, then set the L3, G3, RW3, and LEN3 fi... 19 Mar 2010 17:48

[RFC patch 0/3] RCU head debug objects
Hi, This patchset introduces a debugobjects-based rcu list head debugging infrastructure. The first patch adds the ability to keep track of a "state machine" into debugobjects. The state machine logic is all contained in the type-aware caller. Debugobjects only keep track of the current state (a single integer).... 19 Mar 2010 17:47
