| 2008-04-17 | [S390] Convert monitor calls to function calls. | Heiko Carstens | |
| 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.

| 2007-10-22 | [S390] Add per-cpu idle time / idle count sysfs attributes. | Heiko Carstens | |
| 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> | |||
