irqbalanced fork for i.MX6 devices
License: GNU General Public License v2.0
This is a fork of irqbalanced to add proper support for ARM devices. The regular irqbalanced contains several IRQ misclassifications, which renders it useless on these systems. Also, the way the number of CPUs were being determined was faulty.
The sources are hosted here with Russell King's permission, to make it easier to build irqbalanced with Yocto, for example.
Building follows the regular autotools pattern, which is:
./autogen.sh
./configure
make
make install
Do you know if this is still needed? I used to use it but I switched to the mainstream version a while back and I get glitchy audio sometimes. I just noticed from /proc/interrupts that it might not be working very well.
