[LAD] irq priorities howto posted

hi *! thanks to contributions from a number of ffado folks) (notably stefan richter, kernel firewire developer, the irq priorities howto in the ffado wiki at http://subversion.ffado.org/wiki/IrqPriorities should be in a usable shape. it's split in two parts: the first one shows how to tweak IRQ priorities manually (because it's useful to know, if a bit tedious), and the second shows how to offload the grunt work to rui's rtirq script. however, the general hairiness of messing with kernel thread priorities on an rt kernel demands some more eyeballs on this. i'd welcome user reports and suggestions/corrections from people with in-depth kernel knowledge. no need to cross-post your contributions (unless you want to discuss them widely), i will collate all suggestions and integrate them into the wiki. of course, if you are willing to take the trouble to sign up on the ffado homepage (http://ffado.org/?q=user/register), you are welcome to work on the wiki directly. this information currently resides on ffado.org, because irq tuning is a hot topic for users of firewire audio devices. however, the plan is to move the relevant information upstream into the kernel rt wiki once it' has seen some more review. i'm not currently on the rt users list - if anyone is, feel free to forward this message. i'd appreciate cc:s to my private address in that case. best, jörn
