Re: [LAU] Kxstudio RT kernel vs low latency

Hi all! https://github.com/autch/pm_qos_req I've just seen this. A kernel module to set the cpu_dma_latency to 0. I haven't tested it yet, though. It's probably more friendly than pmqos to set up in a musicmode script (that in my case removes some modules, ubinds usbs and bluetooth, and sets pci priorities). It's for those of you with an older than sandybridge CPUs, newer should probably stick to the pstates hack mentioned by Joakim. On a side note: Does anyone have any factual information on config_irq_time_accounting ? I noticed that it increases the cpu load, but am not sure if it benefits the audio/midi processing. I'm working on a custom kernel config and trying to document how each parameter change affects audio and midi performance for later publishing. Thanks!
