I keep this package in sync with the archlinux stable version. 4.15 will come out when the archlinux community decides 4.15 is ready to transition from Staging to Core.

@Plexcon for your systemd problem, I think you have to recompile virtual box modules (if you use dkms, recompile them).

About the advantages, if you had spent some time reading the other comments, the description and the patches in general you probably had found the culpirt: originally this kernel's main advantage was the inclusion of the BFQ disk scheduler patchset. After its inclusion on mainline linux since 4.12, we found out that you could not enable this scheduler as the default scheduler from the kernel itself, but you rather had to write udev rules for the disks on wich you want to enable the scheduler. After 4.11 we decided to continue this package adding only a patch that enables BFQ by default for all schedulers, the modified xpad module for the steam controller and HZ=1000 for cpu interrupts (wich is probably the setting wich incides more on the tests you posted) that could help increase system responsiveness/snappyness.

Finally, I want to point out that the bfq version that was accepted to merge into the kernel is based on blk-mq, while the old one that was included in this kernel isn't.

This kernel is intended for people that wants to low latency on disks and system usage in general, non for crunching big numbers. Some users gave us a positive feedback using this kernel for games instead of the stock arch kernel or other patched ones.

I hope I helped you, Happy holydays

It's the slowest kernel, I did not install the Xbox 360 gamepad driver ... Where are the advantages?

I was experimenting if CONFIG_HZ=1000 was an actual improvement over 300 and forgot about it. I'm sorry about it I will revert it.

din commented on 2017-10-10 14:21

CONFIG_HZ_1000 and CONFIG_HZ=1000 has been reverted back to 300. Was this an intentional change?

Back to track to the arch kernel :)
Happy compiling!

P.S. to get the BFQ as the default disk scheduler I applied a small patch created by myself. This sucks and I hope to see a better solution from the linux developers soon.

portaloffreedom commented on 2017-10-02 12:28

I'm working on an update for this kernel. With the introduction of BFQ in the mainline kernel, they removed the possibility to choose which disk scheduler to use by default.
This is pissing me off a bit, working on a possible workaround. Keep tuned and sorry for the long wait.

@sten_gun, ah I was unaware it was not based on the same bfq version, in that case you're probably better off using the version we've been using instead of bfq-mq, as I mentioned before it's the only version I've found that doesnt have problems as far as daily use and gaming

sten_gun commented on 2017-08-03 10:51

bfq in 4.12 is based on blk-mq, wich is disabled by default.
If you want to enable it, you have to compile stock arch kernel with blk-mq enabled, and beside this, you have to use udev rules to set the default scheduler for your drive (you can't set bfq as default from the kernel config).
This version (bfq-mq) is slightly different than the original bfq version, and according to the bfq newsletter, is somehow "buggy". I'll give it a try, but I'll think I'll use the original bfq version for at least 1 major version, or when I see that there are no notable bugs in the blk-mq version.

This is about bfq, the other things different are steamos-xpad included by default and 1000Hz cpu freq. When it's time, we'll upgrade this package in order to give users the possibility to enable Bfq and blk-mq based bfq.

just a heads up arch kernel updated to 4.12 on the 7/29, has BFQ scheduler but i dont think it's enabled by default. maintainer probably already knows this, just leaving a reply for reasons to get it upgraded <3

What’s New in Linux 4.12

Among some of the many (many) new features, tweaks, changes and improvements in Linux 4.12:

Improvements to the F2FS (flash-friendly file system)
Initial support for GeForce GTX 1000 w/ Nouveau
Initial Radeon RX Vega support
Support for Intel RealSense SR300 camera, Razer Sabertooth & Mad Catz Brawlstick
USB Type-C port manager
Improved keyboard backlight support in Dell laptop driver
Support for the Intel volume button (intel-vbtn) driver
New ThinkPad T470 hotkey mappings
Sound driver fixes for Skylake, Atom SoCs
New sound drivers for various soundcards/chips

Vega cards release on August 14th, would be really nice to get this kernal to 4.12 by then. Thanks for keeping this updated!
