try IRQTUNE, a Linux IRQ Priority Optimizer

Thanks. I had seen that, however I'm on x86_64 (AMD64) and
unfortunately the prebuilt modules that come in irqtune.tgz are
non-functional on my system.
It doesn't look like the author has touched IRQTUNE for over 10 years
now. Are modules built against kernel 2.0 actually valid in kernel 2.6?
IRQTUNE doesn't build from source, either, on my system:
cc -c -O -I/usr/src/irqtune/include -I/usr/src/irqtune/include/P
-I/usr/src/irqtune -Wall -Werror -Wno-format -D__KERNEL__
-DIRQTUNE_VERSION=\"0.6\" -o load_mod.o /usr/src/irqtune/src/load.c
/usr/src/irqtune/src/load.c:11:24: error: asm/system.h: No such file or
directory
In file included from /usr/src/irqtune/src/irqhigh.c:7,
from /usr/src/irqtune/src/load.c:13:
/usr/src/irqtune/include/irqhigh.h:10:2: error: #error irqhigh: this

So. while I adore the idea of simply being able to insert a module to
remedy the IRQ prioritization (or lack thereof) issue instead of
patching the kernel or installing a kernel alternate from what the
distribution provides, it doesn't seem that IRQTUNE will work for me.
Are the rt patches available as a module? Wouldn't that be cool if the
whole rt stuff could be modularized and simply insmod'ed when the
administrator so-desired real-time functionality?
Thanks,
Lee.
