| |
If you compile an alpha kernel for CONFIG_ALPHA_GENERIC, NR_IRQS is set at 2048. Comment in include/arch-alpha/irq.h: 'Enough for WILDFIRE WITH 8 QBB's'. I'm not sure what a QBB is (Quality BarBecue?) but 2048 interrupts is ridiculous, and overloads /proc/stat.
A /proc/stat that is that long crashes several user-space programs, like vmstat, xosview etc.
The reason I use CONFIG_ALPHA_GENERIC is that I get keyboard timeouts in dmesg at boot-time when I use CONFIG_ALPHA_MIATA, with every kernel > 2.4.9-ac-x; I've not tested earlier.
The alpha kernel mailing-list seems dead.
Is there some reason to keep NR_IRQ at 2048? I'd assume a CONFIG_ALPHA_GENERIC kernel is a lot more common than a Wildfire with 8 QBB's, so it would be better to tone it down a little. Also, can anybody point me at some good ways to debug that keyboard timeout?
