3.2-ck1

These are patches designed to improve system responsiveness and interactivity with specific emphasis on the desktop, but suitable to any commodity hardware workload.

This is an upgrade to BFS 416, trivial bugfixes and a resync from 3.1.0-ck1 . I've changed the versioning to not specify a 3 point release since it usually applies to successive 3 point releases for some time.

Apply to 3.2.x:
patch-3.2-ck1.bz2


Broken out tarball:
3.2-ck1-broken-out.tar.bz2

Discrete patches:

BFS by itself:

Each discrete patch usually contains a brief description of what it does at
the top of the patch itself.

P.S. What this really means is I finished playing zelda.

BFS 0.416 for 3.2.0

Well 3.2.0 is finally out.

I've done a quick and dirty port of BFS from 3.1 with mostly trivial changes and a minor change to idle CPU selection (it will choose the old CPU first now even if the other "thread" is busy on hyperthreaded CPUs). For the most part the changes are trivial only to stay in sync with the new scheduler changes in mainline so it should be a very safe upgrade. Nonetheless, I'm putting this up for testing here because my Ubuntu laptop seems unhappy starting X but that seems 3.2 related rather than BFS related. I've since moved my home desktop to arch linux and have been very happy on that distro.

So anyway here's BFS for 3.2.0 for those who want things hot off the press:

3.2-sched-bfs-416.patch

The -ck patch will not be far behind assuming the first few testers report no problems with this BFS patch. To be honest, the Virtual Memory subsystem has changed so much that I'm having trouble predicting how it will behave now and have no way of confirming the VM patches that go into -ck are even helpful any more, so I'm not even sure if I should continue to support them in light of that.

Besides, I've been too busy playing Zelda - Skyward Sword to really care much about anything code related. I've loved every 3D rendition of Zelda since Ocarina of time, but this latest incarnation is the most amazing game ever...
