I runtime tested your patch. For single-CPU the patch works fine. For SMP I cannot test because Leon-SMP for 3.x doesnt work right now, also without your patch. The last version that I could verify LEON-SMP was 2.6.36, 3.0 should also work, however there your patches dont apply. I'll have to make Leon-SMP work with 3.4 first , then I can test the SMP part of the patch. However I'll write this on my todo list for after easter. As for Leon-SMP is broken right now I would vote for that your patches are applied now and after that to try to fix Leon-SMP. -- Konrad
With SMP working again I tested your timer patch for sparc-leon SMP. It works! -- Konrad # cat /proc/cpuinfo cpu : LEON fpu : GRFPU promlib : Version 0 Revision 0 prom : 0.0 type : leon ncpus probed : 2 ncpus active : 2 Cpu0Bogo : 70.04 Cpu1Bogo : 70.86 MMU type : LEON contexts : 256 nocache total : 5242880 nocache used : 118528 State: CPU0 : online CPU1 : online # cat /proc/timer_list Timer List Version: v0.6 HRTIMER_MAX_CLOCK_BASES: 3 now at 22403528241 nsecs cpu: 0 clock 0: .base: f13d34e8 .index: 0 .resolution: 10000000 nsecs .get_time: ktime_get active timers: clock 1: .base: f13d3520 .index: 1 .resolution: 10000000 nsecs .get_time: ktime_get_real active timers: clock 2: .base: f13d3558 .index: 2 .resolution: 10000000 nsecs .get_time: ktime_get_boottime active timers: cpu: 1 clock 0: .base: f13db4e8 .index: 0 .resolution: 10000000 nsecs .get_time: ktime_get active timers: clock 1: .base: f13db520 .index: 1 .resolution: 10000000 nsecs .get_time: ktime_get_real active timers: clock 2: .base: f13db558 .index: 2 .resolution: 10000000 nsecs .get_time: ktime_get_boottime active timers: Tick Device: mode: 0 Per CPU device: 0 Clock Event Device: percpu_ce max_delta_ns: 1000000068 min_delta_ns: 100000 mult: 4294967 shift: 32 mode: 2 next_event: 2147483646999999999 nsecs set_next_event: percpu_ce_set_next_event set_mode: percpu_ce_setup event_handler: tick_handle_periodic retries: 0 Tick Device: mode: 0 Per CPU device: 1 Clock Event Device: percpu_ce max_delta_ns: 1000000068 min_delta_ns: 100000 mult: 4294967 shift: 32 mode: 2 next_event: 2147483646999999999 nsecs set_next_event: percpu_ce_set_next_event set_mode: percpu_ce_setup event_handler: tick_handle_periodic retries: 0 # -- To unsubscribe from this list: send the line "unsubscribe sparclinux" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
