I finally got tired of needing to pull out the brown book to decode trap
messsages on the alpha, so I've coded up a patch that enhances the printtrap()
function to parse the a[012] registers for a given trap and print out the data
in a more meaningful fashion. For example:
db> x/x 0
0:
fatal kernel trap:
trap entry = 0x2 (memory management fault)
faulting va = 0x0
type = access violation
cause = load instruction
pc = 0xfffffc0000585ac0
ra = 0xfffffc000033c1ec
curproc = 0xfffffe000915ccc0
pid = 22, comm = intr: atkbd0
db>
The patch can be found at http://www.FreeBSD.org/~jhb/patches/trap.patch
Any objections?
