Has anyone had any success performance tuning interrupt handling in 6.2 ?
I know that there is a improved performance handling mechanism in 7.0 but I
kinda stuck using 6.2.
The performance of interrupt handling mechanism on 6.2 during "interrupt
storms" is quiet poor, is there any anything I tweak to improve it ?
Any documentation on the same ?
Also I going to post this also in another list, but I tried using the
PMCStat and kgmon to profile my interrupt handling kernel objects (ko's,
To get a handle on the source of the issue. PMCStat supports profiling ko's
in 7.0 but not 6.2, Kgmon suggests that profiling kernel objects should be
in 6.2, but I have had no success with it. Any documentation I have seen
suggests compiling the sources straight into the kernel rather than using
ko's to profile,
but this is not possible. Has anyone had any luck profiling ko's in 6.2.
