| BenC | afs: add -I/usr/src/linux-headers-`uname -r` to your CFLAGS in qemu | 05:22 |

| BenC | soren: HZ= doesn't make sens with our stock kernel, because it has dynticks | 06:07 |
| JanC | hm, on all architectures? | 06:08 |
| mjg59 | BenC: My understanding is that it still affects the base timer granularity | 06:08 |
| mjg59 | HZ=1000 on i386 would make sense | 06:09 |
| BenC | we got too many complaints about battery usage when we did that | 06:09 |
| BenC | and we have quite a few laptop models that fall into the AMD broken ioapic timer category | 06:09 |
| mjg59 | Yes, but dynticks avoids that being an issue | 06:09 |
| mjg59 | When the system is idle, you still get the power savings | 06:10 |
| Nafallo | mjg59: my acer died ;-) | 06:10 |
| mjg59 | And when it's active, it's no worse | 06:10 |
| Nafallo | mjg59: just thought you might want to know ;-) | 06:10 |

| mjg59 | BenC: Uh. That shouldn't be the case. | 06:11 |
| mjg59 | BenC: Lacking the apic timer isn't a blocker to nohz | 06:11 |
| BenC | mjg59: on the amd laptop I have, I had to add nolapic_timer nohz=on to get it to boot | 06:12 |
| BenC | I meant lapic timer | 06:12 |
| mjg59 | Then there's a bug somewhere | 06:12 |
| BenC | nohz doesn't like not having lapic timer | 06:12 |
| === gnomefreak [n=gnomefre@ubuntu/member/gnomefreak] has joined #ubuntu-kernel | ||
| mjg59 | BenC: I think limiting functionality in the name of providing a small increase in battery life on broken hardware is less than ideal | 06:14 |
| mjg59 | But I was also under the impression that the turion issue had been fixed without the need to disable the lapic timer (the issue was that the code was incorrectly thinking that the timer continued in C2, which it didn't) | 06:15 |
| BenC | maybe I misunderstood the patch then | 06:16 |
| BenC | I can't tell if dynticks is enabled or not...is there a file in sysfs that will show that? | 06:16 |
| mjg59 | Not sure | 06:17 |
| mjg59 | You can work it out from /proc/timer_list, I think | 06:17 |
