Hi,
Is there a specific purpose we print "XT-PIC" for twice in
/proc/interrupts these days on x86 (and maybe other) systems, e.g.:
CPU0
0: 860089 XT-PIC-XT-PIC timer
1: 7165 XT-PIC-XT-PIC i8042
2: 0 XT-PIC-XT-PIC cascade
3: 6 XT-PIC-XT-PIC serial
4: 10 XT-PIC-XT-PIC serial
6: 3 XT-PIC-XT-PIC floppy
8: 0 XT-PIC-XT-PIC rtc0
12: 178 XT-PIC-XT-PIC eth0
14: 37128 XT-PIC-XT-PIC ide0
15: 0 XT-PIC-XT-PIC ide1
NMI: 0 Non-maskable interrupts
ERR: 0
? This looks weird to me and is almost surely an artefact of code we have
in `show_interrupts' in kernel/irq/proc.c:
if (desc->irq_data.chip) {
if (desc->irq_data.chip->irq_print_chip)
desc->irq_data.chip->irq_print_chip(&desc->irq_data, p);
else if (desc->irq_data.chip->name)
seq_printf(p, " %8s", desc->irq_data.chip->name);
[...]
if (desc->name)
seq_printf(p, "-%-8s", desc->name);
with `desc->irq_data.chip->name' and `desc->name' both being "XT-PIC".
Wouldn't it make sense to set the latter to NULL if it was to be the same
as the former? I'll make a patch to implement it unless I hear a valid
argument to the contrary. It's redundant information after all, and
confusing noise IMHO.
