Subject: Hitachi djprobe mechanism
Date: Thu, 21 Jul 2005 22:32:00 -0000	[thread overview]
Message-ID: <OFF65CF944.8CA6968E-ON41257045.007AE2D8-41257045.007B4970@uk.ibm.com> (raw)





The guys from Hitachi at OLS have just shown me an interesting performance
innovation based on krpobes. For high performance probing they use an
inserted jmp. This can't be installed atomically, so to get around that
problem they use a kprobe on the first instance then insert the jmp. Sounds
interesting. They are sending me the details.
