Thanks to folks sending me dmesg output for 3.x, 4.x, and 5.x I now
have an awk script that should do the right thing up until someone
changes the dmesg output format again ;) There's some sample output
at the very end of this message.
find_irq.sh
-----------
#!/bin/sh
dmesg | \
./find_irq.awk | \
sort -n +2 -3
-----end sh script-----
find_irq.awk
------------
#!/usr/bin/awk -f
! /irq\>/ {next}
/at device/ && /on pci/ {irqinfo = gensub(/(^[a-z0-9]+[: ]).*(irq [0-9]+).*([0-9]+\.[0-9]+).*(pci[0-9]+)/, "\\1 \\2 \\4.\\3", 1)
sub(/:/, "", irqinfo)
sub(/ [0-9] /, " &", irqinfo)
print irqinfo
next
}
/on pci/ {irqinfo = gensub(/(^[a-z0-9]+[: ]).*(irq [0-9]+).*(pci[0-9]+\.[0-9]+\.[0-9]+)/, "\\1 \\2 \\3", 1)
sub(/:/, "", irqinfo)
sub(/ [0-9] /, " &", irqinfo)
print irqinfo
next
}
/^pci[0-9]+/ {irqinfo = gensub(/(^[a-z0-9]+[: ]).*(<[[:print:]]+>).*([0-9]+\.[0-9]+) (irq [0-9]+$)/,"\\1 \\4 \\1.\\3 \\2", 1)
gsub(/:/, "", irqinfo)
sub(/ [0-9] /, " &", irqinfo)
print irqinfo
next
}
{irqinfo = gensub(/(^[a-z0-9]+[: ]).*(irq [0-9]+).*/, "\\1 \\2", 1)
sub(/:/, "", irqinfo)
sub(/ [0-9]$/, " &", irqinfo)
print irqinfo
next
}
-----end awk script-----
There is a tab after the initial "\\1" in the substitution strings. I
noticed quite a number of PCI devices that refer only to pci0 or pci1,
so for them I also included the manufacturer's description returned by
the probe.
A question about the line
IOAPIC #0 intpin 2 -> irq 0
Should I be filtering it out or transmogrifying it?
