Hello all,
Â
I've just installed Systemtap, and to start I have a couple of doubts that I
would like to share with you:
Â
1 - Firstly, what I'm trying to achieve is some kind of interrupt handler:
I would like to momentarily interrupt the execution of the OS, and then be
able to run some code of mine (to start, inject a single bit-flip into a
CPU register), and then resume the execution of the OS, with the
possibility of having information on the pre-interruption context. Is this
somehow possible with Systemtap?
Â
2 - I'm using CentOs 6.5 32 bit (kernel version 2.6.32-431.23.3.el6.i686).
Will Systemtap work here? I think this information may be relevant, since
this isn't the last version of the distro, and some other tools I've
already tried to use in the past didn't worked because of my (old) kernel
version.
Â
Thanks and all the best,
JoÃo
