Anyhow with bfq scheduler is accettable this is a notebook and not a multi-core 24x8 server ;-) Cheers, Marco

Seems BFQ should be part of one of the main patterns?

http://algo.ing.unimo.it/people/paolo/disk_sched/

It claims some distro's are defaulting to BFQ as their i/o scheduler.

"BFQ is the default I/O scheduler in Manjaro, Mageia, OpenMandriva, Sabayon, Arch Linux ARM (for Marvell Kirkwood) and ROSA, as well as in the Zen Kernel, the pf-kernel, CyanoGenMod for several devices, and many kernels for smartphones. In addition, BFQ is optionally available in Arch, openSUSE, PCLinuxOS and Gentoo."

Indeed, there's a BFQ OBS repo from Takashi: https://build.opensuse.org/project/show/home:tiwai:bfq

But be aware, that there's a lot of discssion around BFQ upstream at the mement.

It will probably not get merged in it's current form.

Markmail isn't showing anything recent: http://markmail.org/search/?q=bfq#query:bfq%20date%3A201608-201612%20+page:1...

Do you know offhand which list the discussion is on?

linux-block@vger.kernel.org the mailinglist dedicated to the Linux Kernel's Block Layer ;-) Currently there's an RFC patchest from Jens Axbøe allowing I/O-Scheduler's plugging into blk-mq, once this is merged Paolo can convert his BFQ to blk-mq and then has a chance to get it merged. The current blk-sq version won't be merged though. But I expect this to be in kernel v4.12 earliest (4.10 development is over and the merge window will open next week AFAICS, and it'll take one cycle to get the new MQ IO schedulers in and at least one cycle for BFQ). Until then you'll have to live with an out-of-tree version.
