yum repository for kernel-rt ?

Hello.

Is there a yum repository for kernel-rt?

Or should I get it from planetccrma-core?
http://ccrma.stanford.edu/planetccrma/software/installtwosix.html

I'm using Fedora 7 and I really would like to prioritize one particular PCI device that I have (which unfortunately sits on IRQ 20, the very last) so that it has priority over sata_nv, libata, eth0, and eth1. Am I correct in believing that kernel-rt will allow me to do that?

Thanks,

Lee.

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 only works/is needed for x86/PC architecture -- sorry In file included from /usr/src/irqtune/src/load.c:13:
/usr/src/irqtune/src/irqhigh.c:8:20: error: asm/io.h: No such file or directory
cc1: warnings being treated as errors

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.
