Re: How much RT optimization is still needed?
Also note that udev-rtirq (https://github.com/jhernberg/udev-rtirq) doesn't work correctly for xhci.

Re: How much RT optimization is still needed?
turbidh20 your method of finding IRQ doesn't work for xHCI controllers. These controllers use MSI/MSI-X interrupts and allocate dedicated interrupt for each connected device (at least my old uPD720202 do). 02:00.0 USB controller: Renesas Technology Corp. uPD720202 USB 3.0 Host Controller (rev 02) (...

Re: Solid State Logic SSL2 - problems while playback
I guess it requires implicit feedback quirk, just like SSL2+

Re: Scarlett 18i20 gen 3 Linux - Crackling Audio
Also I doubt that 18i8 will work correctly with my patch. I should probably add additional filtering of sample rates on the output interface for this device.

Re: Saffire 6 USB 1.1 no inputs available in Jack
Mr (or Mrs) Puleglot. Thank you so much for your help with this. If there's any other testing I can help with please ask. Oh, just remembeerd - I get a lot of "unable to change format on ep #82" messages when the usb-audio module is loaded, but it doesn't seem to affect anything. Thanks for testing...

https://git.kernel.org/pub/scm/linux/ke ... 80c63bf77f
But it is not fixing all the problems with implicit feedback AFAIS.
