[S390] Convert monitor calls to function calls. 2008-04-17T05:47:05+00:00 Heiko Carstens heiko.carstens@de.ibm.com 2008-04-17T05:46:23+00:00 43ca5c3a1cefdaa09231d64485b8f676118bf1e0 Remove the program check generating monitor calls and use function calls instead. Theres is no real advantage in using monitor calls, but they do make debugging harder, because of all the program checks it generates.

[S390] Add per-cpu idle time / idle count sysfs attributes. 2007-10-22T10:52:47+00:00 Heiko Carstens heiko.carstens@de.ibm.com 2007-10-22T10:52:39+00:00 fae8b22d3e3e3a3d317a7746493997af02a3f35c Add two new sysfs entries per cpu: idle_count and idle_time. idle_count contains the number of times a cpu went into idle state. idle_time contains the time a cpu spent in idle state in microseconds. This can be used e.g. by powertop to tell how often idle state is entered and left. # cat /sys/devices/system/cpu/cpu0/idle_count 504 # cat /sys/devices/system/cpu/cpu0/idle_time 469734037 us Cc: Arjan van de Ven <arjan@infradead.org> Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
