During this summer, I'll work on the pkg_install tools to add complete

After reading though the kernel source I realise what I want isn't
implemented at the moment but I wanted to discuss if this feature

Basically I want to see counts of how many interrupts for a particular
interrupt have fired on each core. Linux has provided this kind

Hi FreeBSD-Hackers,
netstat -i will print out statistics for each interface, including
input/output packets, input/output bytes, and input/output errors. Now
packets and bytes columns seem to be absolute counts, whereas the

I am running a amd64 FreeBSD 7.2 inside a VMWare, and DTrace has been

Hi,
I've been playing with memguard(9) and so far it works well until it
starts to run out of memory. For those who don't know, memguard is a
replacement debugging malloc for the kernel, which is designed to
catch use after free errors. It achieves this by setting any free'd
pages to read-only,

I'm having a problem with memguard(9) on FreeBSD 7.1 but before I ask

When in interrupt context malloc must be called with M_NOWAIT, this is

I found this useful tool called pahole[1]. It basically finds holes

Would have a hole between foo and bar of 4 bytes because both for and
bar have been aligned on a 8 byte
