[linux-audio-dev] rt irqs patch to 2.4.23

[Kai Vehmanen]

Hello all,

here's a new approach to improving kernel RT performance. This
specifically tries to improve interrupt latencies, so it's complementary
to the existing preempt and lowlatency patches.

""Metrowerks Senior Software Engineer and veteran real-time programmer 
Bernhard Kuhn has created a Linux kernel patch that he claims enables 
hard, real-time performance in the Linux kernel by adding priorities to 
interrupts and spinlocks. Kuhn believes his approach to be more "natural" 
and akin to traditional real-time operating systems (RTOSs) than the 
dual-kernel approach taken by real-time projects such as RTAI and RTLinux, 
and he is hopeful that his patch might one day win enough interest and 
support to become part of the official Linux kernel tree.""
