3.5-ck1, BFS 424 for linux-3.5

Thanks to those who have been providing interim patches porting BFS to linux 3.5 while I've been busy! Finally I found some downtime from my current coding contract work to port BFS and -ck to linux 3.5, and here is the announce below:
 
 
These are patches designed to improve system responsiveness and
interactivity with specific emphasis on the desktop, but suitable to
any commodity hardware workload.

Apply to 3.5.x:
http://ck.kolivas.org/patches/3.0/3.5/3.5-ck1/patch-3.5-ck1.bz2
or
http://ck.kolivas.org/patches/3.0/3.5/3.5-ck1/patch-3.5-ck1.lrz

Broken out tarball:

or
http://ck.kolivas.org/patches/3.0/3.5/3.5-ck1/3.5-ck1-broken-out.tar.lrz

Discrete patches:

Latest BFS by itself:

Code blog when I feel like it:

This is a resync from 3.4-ck3. However, the broken out tarballs above also 
include the upgradeable rwlocks patch, and a modification of the global 
runqueue in BFS to use the urwlocks. These are NOT applied in the -ck1 patch, 
but can be applied manually at the  end of the series as indicated by the 
series file. It is currently of no demonstrable performance advantage OR 
detriment in its current state, but is code for future development.

Enjoy!

BFS and -ck delays for linux-3.5.0

Once again I find myself writing a post saying there will be delays with the resync of BFS and -ck for the new linux kernel. This time the reason for most people would be a quite unexpected development. As you may have read on this blog last year, I got invited to interview with Google for a job as a software engineer and then in the end I got turned down due to lack of adequate breadth of knowledge. This was probably for the best for me anyway since I have a full time unrelated career and the jump would have been too great. Anyway a small company noticed the work I had done on cgminer with bitcoin and openCL work and asked if I was interested in writing some software for them. The work involves writing openCL frameworks so they can provide distributed computing capability to clients. They were quire happy to forego any of the regular interview details or pretty much anything that is normally involved in employing someone and before long we started talking contracts instead. Since the work itself actually looked like a lot of fun, I decided to go with the opportunity.

Anyway, long story short, I'm doing a little bit of contract work for them and my kernel work will take a slightly lower  priority in the meantime. I'm not abandoning it, but it will be delayed some more before the next release. Apologies for any inconvenience this may cause in the interim.
