Iprobe is an alpha-only system profiling suite which I'm porting from Linux/alpha to FreeBSD. Iprobe works by using the hardware profiling support built into alpha cpus. In a nutshell, what Iprobe does is to setup the alpha performance counters to sample the pc at a fairly high rate & dumps those pc samples out to user space. Then some code runs to map the sampled PCs to functions. You get a bit more than that (like the PSL word, so you can tell if you're in the kernel or userland, what the ipl is, etc).

Hopefully, this list will one day be obsoleted by DEVFS, but for now
|
|
this is the current allocation of device major numbers.
|
|
|
|
For local use, you are encouraged to use the reserved numbers.
|
|
|
|
If you intend the driver to be available, send email to the
|
|
hackers@freebsd.org mailing list to see about having a number
|
|
reserved for you.
|
|
|
|
The most "complete" version of this will be the one in FreeBSD-current.
