Kernel with BFQ patch [updated to 3.6.10] + cyrillic support

[moonman]

BFQ is now in the official kernel. To activate, refer to the uboot installation guide and scroll down to Setting BFQ as the default I/O scheduler

I'll leave the following for reference

linux-kirkwood hasn't been updated in a month or so (3.6.4), so here's 3.6.10 for the community.

Official changelog 3.6.10

This kernel is with the BFQ patch and BFQ as the default i/o scheduler
You can read more about BFQ here: http://algo.ing.unimo.it/people/paolo/disk_sched/

If anybody is interested, here you can find PKGBUILD and config

Be sure to have the new U-Boot before installing this kernel or your device won't boot!

How to install:

$this->bbcode_second_pass_code('', 'pacman -U http://music4dance.mine.nu/Downloads/ArchLinuxArm/linux-kirkwood-3.6.10-0-arm.pkg.tar.xz http://music4dance.mine.nu/Downloads/ArchLinuxArm/linux-headers-kirkwood-3.6.10-0-arm.pkg.tar.xz')

Very interesting project: "BFQ achieves up to 30% higher throughput than CFQ on hard disks with most workloads". I wonder due to what factors? Would you be interested to measure write speed over Samba from a PC to a BFQ controlled EXT4 formatted Pogo disk?

[moonman]

I think you are missing the point here. The key word is "workload". BFQ is better when multiple applications are accessing a hard drive at the same time. For example you are copying 1TB of files to the hdd and want to stream some videos over minidlna and webserver is serving some other files. Minidlna may choke at this point so that's when BFQ comes in. Throughput will be exactly the same as it is limited to 30MB/s by USB interface as was mentioned before.

I think my Soekris 4801 needs this...

I'll see about incorporating this into the official linux-kirkwood tree, with the default set to cfq for now.

I've compiled kernel 3.5.3 with bfs + bfq for my desktop running kubuntu and there's a very noticeable difference.

Thanks pepedog Obviously I am not familiar enough with pacman

If I've kernel 3.5.2 now, should I update directly to 3.5.4, or in steps: to 3.5.3, then 3.5.4 ?

There were errors when trying to upgrade to 3.5.3. Are any errors expected (covered or not by "News"), when updating to 3.5.4? I think any upgrade suggestion should be accompanied by such info, and its not really "news", but "update issues".

This isn't the official one. Pay attention.
