| |
Version 6.1 of the ZAPHOD single priority array scheduler patches for the 2.6.10 kernel are now available for download and evaluation from:
<http://prdownloads.sourceforge.net/cpuse/patch-2.6.10-spa_zaphod_FULL-v6.1?download>
This contains the extra per runqueue CPU statistics for improving GA fitness functions that we discussed.
struct runq_cpustats { #ifdef CONFIG_SMP unsigned long long timestamp_last_tick; #endif unsigned long long total_delay; unsigned long long total_rt_delay; unsigned long long total_intr_delay; unsigned long long total_fork_delay; unsigned long long total_sinbin; };
total_delay - is total time spent by tasks waiting for CPU on this runqueue total_rt_delay - as for total_delay but only for real time tasks total_intr_delay - is total time spent by tasks waiting for CPU on this runqueue after being woken to service an interrupt total_fork_delay - is total time spent by tasks waiting for CPU on this runqueue for their first time slice after forking
