Ingo explains the problem that he is working to address. I took a look at latencies and indeed 2. GHz+ x. 86 system - even when using the fully preemptible kernel! Any code point that does might. So the patch activates these debugging checks to be scheduling points. This reduces complexity and impact quite significantly. I took a look at latencies and indeed 2. Revision History Revision 0.1 2006-12-07 First release Revision 0.2 2006-12-13 CONFIG Kernel preemption and realtime linux kernel with preempt. In order to reduce the latency, the CONFIG What is a real-time system? I am trying to attach and build a kernel (3.0.35) with PREEMPT. GHz+ x. 86 system - even when using the fully preemptible kernel! I'll split this up into small pieces once there's testing feedback and actual audio users had their say!) unlike the lowlatency patches, this patch doesn't add a lot of new scheduling points to the source code, it rather reuses a rich but currently inactive set of scheduling points that already exist in the 2. Any code point that does might. So the patch activates these debugging checks to be scheduling points. This reduces complexity and impact quite significantly. Sometimes lock- break was necessary as well. We'd love to learn about workloads that still cause audio skipping even with this patch applied, but i've been unable to generate any load that creates higher than 1msec latencies. Real-time patch from Ingo Molnar adds CONFIG. Here’s the simplified algorithm how to compile RT kernel: 1. Set up the arm-linux-gnueabihf tools 2. Download kernel source 3. If a real-time Linux application requires latencies smaller than single-digit milliseconds, use of the CONFIG This patch allows nearly all of the kernel to be preempted, with the exception of a few very small regions of code. Interrupt performance on linux kernel with RT patches - should be better? In reply to: Ingo Molnar: 'Re: Config: add rt Signed-off-by: Robert Nelson <[email protected]> Loading branch information.
