Here are couple of patches providing debug register allocation mechanism and kernel API to register watchpoints.

Jeff, I was wondering if there are plans to support a method to register watchpoints for memory data access with kprobe. On x86, it's possible to watch for read/write access to arbitrary memory locations via DR memory registers.

kprobe support for memory access watchpoints
I was wondering if there are plans to support a method to register watchpoints for memory data access with kprobe. On x86, it's possible to watch for read/write access to arbitrary memory locations via DR memory registers. Perhaps register_kprobe() could be modified to support this or perhaps some new function. This would probably be difficult based on how differently kprobe works vs. how the DR registers work. I thought I would send an email because you might be doing or thinking something similar.
