How about i instead do the comprimise:
* i'll pin all other swi's
* default swi isn't pinned by default, but one can flip on a sysctl at
boot time to pin it
How's that sound?
And also please a sysctl that disables any swi pinning.
It is sometimes useful to change the default cpuset, for instance to
allocate a subset of CPUs to some particular applications and not
FreeBSD. Having kernel threads pinned prevents this from happening since
they are in the default set.
(Note that some network drivers are also culprits here, though
disabling MSI-x in them is a workaround).
later,
Peter.
