That's what I like  
Is it a rollup from Jake's 2.6.17 original stuff or a brand new stuff from him ???
Gonna try soon

no genetic.patch is not a roll up its empty, like origin.patch is in mm-sources, i use it with quilt when i manage my patches, its like a marker i can jump to easily, the important genetic patches are the ones that follow

are you sure you have 2.6.21-rc2-skunk1.1 because I am 99% sure that compile error should not happen, I think you have skunk1.0 or something, delete anything skunks-sources-2.6.21 related from /usr/portage/distfiles and re-emerge
EDIT: this is straight out of my ingosched.c:
| ingosched.c line:402: | #ifdef CONFIG_SMP
unsigned long cpu_load[3];
unsigned char idle_at_tick;
#ifdef CONFIG_NO_HZ
unsigned char in_nohz_recently;
#endif
#endif

yeah i get that BUG too with genetic aio, idk if it has to do with the -rc prepatch or an -mm patch or if it has to do with the kobj implementation in genetic-aio or if it has to do with my port of genetic aio to >=2.6.20 (my porting might not be 100% proper); however it dosent crash on my computer so maybe its OK for now, does your system seem stable?, you should be able to use dynticks(no_hz) , i have it enabled on my system...... is your computer a uni-processor machine?

Would be nice to add to the first post, that this applies to -mm kernel, not the mainline kernel  |

am pretty sure i have the latest skunk-sources. this are some of the dmesg messages.
any clue? |
yeah i get that BUG too with genetic aio, idk if it has to do with the -rc prepatch or an -mm patch or if it has to do with the kobj implementation in genetic-aio or if it has to do with my port of genetic aio to >=2.6.20 (my porting might not be 100% proper); however it dosent crash on my computer so maybe its OK for now, does your system seem stable?, you should be able to use dynticks(no_hz) , i have it enabled on my system...... is your computer a uni-processor machine? |
skunk1.2 compiles fine with the tickless timer and boots.
the errors are still there.
my computer is a uni-processor.
skunk1.1 used to hardlock after a few minutes of use. now let's see if skunk1.2 is going to be more stable.
kernel is really fast. very very fast. am just hoping the errors are ironed out.
thanks for always playing forward with the mm series. good job.

well skunk1.2(genetic) still hardlocks after say 5 minutes of use.
am still convinced once the problems are ironed out skunk1.2 will be one of the fastest kernel here.

the hardlocks I think might be caused by the experimental genetic patches I am using... ( the ones with kobj integration), the genetic patches I am using are the handy work of someone other than Jake.... if I cant get the bug worked out of it I will go back to the last patches Jake released for 2.6.17... do you get hardlocks with with out genetic ingo cpu or just with it

What version of rsdl.c are you running, that code isn't correct at all.
Should be:
| Code: | update_cpu_clock(p, rq, now);
if (p == rq->idle)
/* Task on the idle queue */
wake_priority_sleeper(rq);
else
task_running_tick(rq, p);
#ifdef CONFIG_SMP
update_load(rq); |

I gathered something like that happened. If it wasn't clear this change caused
massive scheduler damage with no cpu accounting whatsoever occurring. I
recommend putting it in your hotfixes/ dir if you're not planning an -mm2
soon. |
EDIT: -mm2 is out so hopefully this is all straightened out
