Subject[RFC][PATCH 00/32] Nohz cpusets v2 (adaptive tickless kernel)
Date
*** BLURB HERE ***

Frederic Weisbecker (32):
nohz: Separate idle sleeping time accounting from nohz logic
nohz: Make nohz API agnostic against idle ticks cputime accounting
nohz: Rename ts->idle_tick to ts->last_tick
nohz: Move nohz load balancer selection into idle logic
nohz: Move ts->idle_calls incrementation into strict idle logic
nohz: Move next idle expiry time record into idle logic area
cpuset: Set up interface for nohz flag
nohz: Try not to give the timekeeping duty to an adaptive tickless
cpu
x86: New cpuset nohz irq vector
nohz: Adaptive tick stop and restart on nohz cpuset
nohz/cpuset: Don't turn off the tick if rcu needs it
nohz/cpuset: Wake up adaptive nohz CPU when a timer gets enqueued
nohz/cpuset: Don't stop the tick if posix cpu timers are running
nohz/cpuset: Restart tick when nohz flag is cleared on cpuset
nohz/cpuset: Restart the tick if printk needs it
rcu: Restart the tick on non-responding adaptive nohz CPUs
rcu: Restart tick if we enqueue a callback in a nohz/cpuset CPU
nohz: Generalize tickless cpu time accounting
nohz/cpuset: Account user and system times in adaptive nohz mode
nohz/cpuset: New API to flush cputimes on nohz cpusets
nohz/cpuset: Flush cputime on threads in nohz cpusets when waiting
leader
nohz/cpuset: Flush cputimes on procfs stat file read
nohz/cpuset: Flush cputimes for getrusage() and times() syscalls
x86: Syscall hooks for nohz cpusets
x86: Exception hooks for nohz cpusets
x86: Add adaptive tickless hooks on do_notify_resume()
nohz: Don't restart the tick before scheduling to idle
rcu: New rcu_user_enter() and rcu_user_exit() APIs
rcu: New rcu_user_enter_irq() and rcu_user_exit_irq() APIs
rcu: Switch to extended quiescent state in userspace from nohz cpuset
nohz: Exit RCU idle mode when we schedule before resuming userspace
nohz/cpuset: Disable under some configs
