-bfs
This branch is for bfs related development, which consider stable and apply upon original bfs code.
Changes:
-- Find a regression commit and revert it at this time.
-- Sync up with mainline 3.16.2
linux-3.16.y-bfs
-vrq
This branch is for bfs vrq solution development, it should be considered experimental and just use for testing.
Changes:
-- Sync up with mainline 3.16.2
-- Rebased latest -bfs branch.
-- Add some bug fix to vrq code.
linux-3.16.y-vrq
-gc
Changes:
-- sync up with mainline 3.16.2
-- merge -bfs branch instead of tracing all bfs related commits.
linux-3.16.y-gc
At the moment I'm a bit confused to decide which of these branches to use at first. -gc or -bfs? I compared the patches being available from you for BFS before this update -- but, so far, not in depth, not looking into the code, and I'm missing some ones. Did you merge those / integrated them into the others or abandoned them? So, don't misunderstand "missing".
ReplyDelete"Missing" in -bfs:
* Refine locality to ranking and siblings cache idle code
* locality doesn t need to be kmalloc
* Remove get_cpu put_cpu in try_to_wake_up
* Remove unnecessary resched_suitable_idle in schedule
* Fix runqueues decarelation
* Doesn_t reschedule idle or deactivated task
Added in -bfs:
+ Refine resched_best_idle call logic in schedule
[As it doesn't make sense to discuss the commit numbers on here I wrote filesystem-friendly topic abbreviations to the patch-files' names to quickly retrieve them. So you might miss some () or =! in the list above.]
Best regards,

Delete-bfs branch is used for my bfs development, every individual commit is on it.
-gc branch doesn't trace every individual commits, just merge the -bfs branch.
* Refine locality to ranking and siblings cache idle code
* locality doesn t need to be kmalloc
It seems that this commit cause regression based on testing. So I have decided to revert it at this time and try to work it out in next release.
* Remove get_cpu put_cpu in try_to_wake_up
should be merged into [BFS] Sync up try_to_wake_up* functions
* Remove unnecessary resched_suitable_idle in schedule
is merged into * Doesn_t reschedule idle or deactivated task and it's a separate commit in -gc b/c it provide great performance boost and I want it to be easy be seem and be merged.
* Fix runqueues decarelation
is merged into other commit that I can't remember, but it's there.
Thanks for your careful investigation. :)
Thanks for your quick clarification. If I had looked closer at the code I wouldn't have needed to bother you ;-) Except for the two patches you plan to rework, all the "missing" code is there, with respect to your changes.
Delete(Btw, the * Fix runqueues declaration code is now in * Make cpu_rq cpu a macro instead of a function call.)
The -bfs branch is now running for ~18h without problems, thank you,
