X-Git-Tag: v2.6.31-rc1~421^2~1 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=294ae4011530d008c59c4fb9847738e39228821e;p=pandora-kernel.git ftrace: fix typo about map of kernel priority in ftrace.txt file. Fix typo about chart to map the kernel priority to user land priorities. * About sched_setscheduler(2) Processes scheduled under SCHED_FIFO or SCHED_RR can have a (user-space) static priority in the range 1 to 99. (reference: http://www.kernel.org/doc/man-pages/online/pages/ man2/sched_setscheduler.2.html) * From: Steven Rostedt 0 to 98 - maps to RT tasks 99 to 1 (SCHED_RR or SCHED_FIFO) 99 - maps to internal kernel threads that want to be lower than RT tasks but higher than SCHED_OTHER tasks. Although I'm not sure if any kernel thread actually uses this. I'm not even sure how this can be set, because the internal sched_setscheduler function does not allow for it. 100 to 139 - maps nice levels -20 to 19. These are not set via sched_setscheduler, but are set via the nice system call. 140 - reserved for idle tasks.
