2.6.12-rc2-love1 release info
There is no name for this release , but We can naming it "a release"  
Now some infos about the release , everybody like the infos

Please don't report any bugs to gentoo-devs or bugs.gentoo.org.
We are making patchset for x86 . We will be not able to help You with x86_64 
If You want support or jusk ask about something - please join #love-sources on freenode or just
post in the love-sources thread in "Unsupported Software" forum on forums.gentoo.org
check also love-sources.org |
| A mini How-To use this love and some review about this release called a release wrote: |
Short info about main features .
This release is based on Peter Williams PlugSched4.0
I also made a genetic nickscheduler patch for this version of plugsched.
So now You can choose a CPU Scheduler at booting moment via kernel BOOTPARAMS line
In Love-Features menu You can choose the default CPU Scheduler.
if You will add "cpusched=nicksched" the kernel will boot with nickscheduler or genetic nickscheduler
depending on selection in menuconfig ( genetic nickscheduler on/off etc. )
available options are :
"cpusched=nicksched" - nickscheduler or genetic nickscheduler
"cpusched=staircase" - staircase 10.7 cpu scheduler
"cpusched=ingosched" - ingosched - Ingo Molnar CPU scheduler from vanilla
"cpusched=zaphod" - P.Williams Zaphod CPU scheduler
"cpusched=spa_no_frills" - P.Williams Single Priority Array CPU Scheduler
available IO Schedulers are :
- deadline
- no-op
- anticipatory or genetic anticipatory ( menuconfig selection )
- CFQv2 with TIMESLICED DESIGN and fixes from 2.6.12-rc2-mm1
You can choose default IO Scheduler from Love-Features or via kernel BOOTPARAMS line
If You will add "elevator=cfq" the kernel will bot with cfq io scheduler
You can also switch it at runtime for example via script from /love_src/!extras/sched_change_script
of via /sys/block/hdX/scheduler/queue interface.
possible option are : cfq , deadline , noop, anticipatory
If You are using genetic nicksched or anticiapatory You can watch /proc/genetic/***
!IMPORTANT! now all interfaces to cpu scheduler are moved from /proc to /sys/cpusched
so base_time_slice and genetic_bonus for nicksched or interactive and compute mode for staircase
are in /sys/cpusched/scheduler_name.
example .torsmorc theme for watching genetic nicksched fluctuations is in love_src/!extras dir.
If You have selected Genetic Library and Genetic NickScheduler in Love-Features menu.
You can set some additional Genetic NickScheduler options :
a) Base_Timeslice range ( 4 - 32 - std ) --->
You can select the range of base_timeslice for nickscheduler : 4-16,4-32,4-64,4-128.
b) [*] Genetic Bonus Calculation (NEW)
This is adding simple genetic parameter to the bonus calculations.
c) [*] Give a bonus for a long timeslice (NEW)
When no real waiting occurs the timeslice should be large to avoid overhead.
d) [*] MAGNITUDE (NEW)
Base Timeslice will be generated based on multiply of 4 only in 8-32 range.
This can give better results for rating function.
If You have selected "normal" NickScheduler You can select base timeslice from 16,32,64,128
You can also select VM_MAPPED for Mapped_Watermarks3 beetwen 33,66,95.
In this kernel is also KEXEC. You can run another (or this) kernel without reboot now.
For using it , please emerge kexec-tools and search the net for some how-to
On the forums or google is many of it

it is working here fine with 6629-r4 .
also it is working with 7*** series .
I have problems with 7*** and renderaacel + composite but this is on every kernel and it is my geforce2gts . I must upgrade gfx card to some new for using 7***.
cheers.

Compiled, and ati works! Thanks. I'm on nickcase right now, but I'll try staircase soon...
EDIT: never mind, it doesn't work... still, it's not really important for me, and the kernel seems nice (on staircase now..); I still can't judge on responsiveness, that'll have to wait a bit.
BTW, what's that single array scheduler? I've never seen it before, is it for servers or something?

The new 7174 driver restores support for TNT2 and similar cards.. the old P2 350mhz behind me has a TNT2 and is happily using that version. Although from the looks of other posts, that might not work on this kernel if you want renderaccell and Composite. no biggie really if you don't use those things anyway. |

7*** renderaccel badness on nvidia cards isnt related to any kernel.
it is just nvidia 7*** series fault.
cheers.

yes, this really sucks. I expected the second 7xxx to fix it (7174). It didn't. |

slightly annoying warning (changed include/asm/processor.h to include/asm-x86_64/processor.h to reflect the fact that this only affects, afaik, x86_64), this warning pops up a lot because just about every .c file includes include/asm/processor.h

no problems here, just played sc4
yeah! this release is like it rocks! the sched overkill
currently using "ck-setup" (staircase/cfq) on a reiser4 system \\o o// seems like problems with staircase+reiser4 are gone, still bit higher cpu as with nicksched for exp when copying files, but much better than last time i tried staircase

I wasn't being a smartarse,fallow.I think its makes sense that I report the errors that I see just in case it is an easy fix rather than something non-trivial.I'm actually pretty happy with rc1-love1 but wanted to see if the new staircase was an improvement at all. |

cheers.
