Priority Inheritance?Priority Inheritance?Posted Jul 19, 2006 23:30 UTC (Wed) by corbet (editor, #1)In reply to: Priority Inheritance? by Felix_the_Mac Parent article: Kernel Summit 2006: Realtime Priority inheritance is in 2.6.18. See this article for a description of the PI patch. There's not really any difference between user-space and kernel-space PI - it's all implemented in the kernel in any case.

Priority Inheritance? Posted Jul 20, 2006 0:09 UTC (Thu) by mingo (subscriber, #31122) [Link] yes. The kernel/rtmutex.c code which implements user-space PI (the new PI-futexes API) is the exact same code used for preemptible spinlocks too in -rt. It was not entirely trivial to merge the two uses into the same subsystem, but it's reality now. (And i dont want to take all credit for it, large portions of this solution were designed and written by Thomas Gleixner, Esben Nielsen and Steven Rostedt.)
