The v2 Rotary Interactivity Favor Scheduler

[3766691]

looks good to me


compiling libreoffice right now

probably will add some more spice to it to see how it works out


thanks ! great job

Thanks for comments.
I want someone to try RIFS-ES V1 also. If you have time could you help me to try? Thanks.
If it works better than RIFS-V2-Bugfix2 then RIFS-ES will be combined to RIFS.

the patch is monolithic right ?

thanks !


edit:

ok, seemed that the build went wacko - I forgot to make clean mrproper before

d'oh !

2nd compile went fine

my bad


will try now


edit2:

ok doesn't built - same error

seems genkernel has something against it


someone else has to try it


thanks !

Edit 1:
Sorry for my fault.
The header file sched.h in the patch is not synchronous to my version that I am using.
I will fix it after a few hours.


Edit 2:
Ok, I have posted the new one.

I'll probably try it tomorrow or within the next days - currently my box is busy working ...

looks good to me

thanks ! great job

results:

ok, I put the rifs for 3.4 to some test (the one without ES / enhanced scheduling)

compiling libreoffice + rsyncing data on encrypted partitions (1 TB) to zlib-compressed btrfs + 1080p HD flash/youtube video

everything super-smooth and interactive

== keeper


best recent kernel so far


I combined it with The Barbershop Load Distribution algorithm IMO a winning combination

BLD is much simple and perform better than Vanilla load balancing.But now BLD can just work with mainline.

yeah, these are way too oversized/overheaded for desktop or small system's usage


currently trying out RIFS-ES

thanks Chen !

Hi KOT.
Here is the benchmark about latency

yeah, what I experienced so far

RIFS vs. RIFS-ES isn't much difference noticable under "normal" productivity load

but under pretty heavy load it probably is noticable


BFS was already quite good but had some issues since I upgraded my hardware from Core 2 Duo to Core i7 Quad (+ HT) at least it wasn't the same


CFS improves with newer kernel releases and it quite nice with autogroup but obviously needs improvements (little sound/video stuttering from time to time during heavy i/o, etc.)


RIFS / RIFS-ES is best so far - very very good for desktop usage


Chen, could you also make a port for 2.6.35, 2.6.39 and 3.0/3.1 kernels ?


I believe the XDA devs might love it (I'm an XDA dev myself) and it would definitely improve smoothness and responsiveness with less overhead on the phones

besides that RIFS would get more testing, fame and geek status


thanks for considering

Regarding my stat.h error:
I am using gcc-4.6. Are you using an older compiler version?
