Kernel RT i variants

La informació més recent de la situació del realtime kernel està a:
Hi ha una discussió a la LAU sobre els diferents kernels RT, avantatges i inconvenients, doncs el futur per a la 10.10 és incert:
Hello everybody, Many are confused about the various realtime kernels, so here is a reminder of the situation as of Sept. 2010 (but _please_ see https://help.ubuntu.com/community/UbuntuStudio/RealTimeKernel , which is more detailed and continuously updated). ***Summary*** vanilla = unpatched kernel straight from kernel.org generic = vanilla + ubuntu sauce (it's the default ubuntu kernel) The *soft realtime kernels, prepared by changing build-time parameters* preempt = generic + mild configuration to reduce latency lowlatency = generic + aggressive configuration to reduce latency The *hard realtime kernels, prepared by applying a big patch* from Ingo Molnar to the kernel source before building: realtime = vanilla + patch (hard to maintain and stabilize because merging 2 pieces of code is never easy) rt = generic + patch (even harder to maintain and stabilize because merging 3 pieces of code is harder than 2) ***Availability*** - for Maverick, generic will be the only kernel in the archives, thus the default kernel for ubuntu and ubuntustudio, but Alessio has been maintaining a PPA providing lowlatency and realtime - for Natty or later: work is being done to include lowlatency in the official archives and make it the default ubuntustudio kernel I hope this clears some doubts. By the way, this confusion is only going to get more intense at release time (less informed / technical users). Could we include some kind of note informing users about this? Why not a "RealTime kernel help" item in the Audio Production menu, redirecting to the wiki page? Good day, -- Ronan Jouchet
