Revert the revert so we go back to the state > Fedora has traditionally been in. Ack, I was planning on doing this myself but you beat me to it, thanks for taking care of this. Note that 3.17 will have this patch: https://git.kernel.org/cgit/linux/kernel/git/rafael/linux-pm.git/commit/?h=… Which fixes the 2 steps being taken for one keypress problem while keeping the acpi brightness_switch behavior enabled, so that people who have an acpi-video controlled backlight and a userspace which does not do backlight control (e.g. windowmaker). So for 3.17 we should IMHO drop the revert-revert and stick with upstream behavior. Alternatively we could apply that patch now instead of the revert-revert. Regards, Hans

fedora 14 kernel performance with ip forwarding workload
by Jesse Brandeburg 04 Jun '15

04 Jun '15

The other day I was running the stock fedora kernel on my ip forwarding setup, to see what the performance was, and the performance wasn't very good. system is S5520HC dual socket 2.93GHz Xeon 5570 (Nehalem) with 3 quad port 82580 adapters (12 ports). Traffic is bidirectional 64 byte packets being forwarded and received on each port, basically port to port routing. I am only using 12 flows currently. The driver is igb, and I am using an affinity script that lines up each pair of ports that are forwarding traffic into optimal configurations for cache locality. I am also disabling remote_node_defrag_ratio to stop cross node traffic. With the fedora default kernel from F14 it appears that CONFIG_NETFILTER=y means that I cannot unload all of netfilter even if I stop iptables service. perf showed netfilter being prominent, and removing it gives me much higher throughput. Is there a reason CONFIG_NETFILTER=y ? Isn't it a good thing to be able to disable netfilter if you want to? Jesse

Rawhide backlight patches
by Josh Boyer 22 Aug '14

22 Aug '14

Hi Hans, With 3.17-rc1, I had to drop the following patches: asus-wmi-Add-a-no-backlight-quirk.patch This one seems to have been solved in a different manner upstream with commit d8c66f62992dac3a92cbc5f16791557100c7a068. eeepc-wmi-Add-no-backlight-quirk-for-Asus-H87I-PLUS-.patch This one depends on the no_backlight field added to the quirk struct in the previous patch. Both of them were marked as "Sent for 3.16" and that obviously didn't wind up happening, so I've dropped them for now. The eeepc change looks to be the only one that is really of concern, but there's no clear solution there to me. If you have an alternative patch for it, let me know. josh

3.17 for f17?
by Bruno Wolff III 14 Aug '14

14 Aug '14

With the latest slip it looks like 3.17 rc6 will be available by beta freeze and that most likely (no rc8 or other odd delays) we could have 3.17 available as a zero day update for the beta release. And then we would have 3 weeks after the beta release before final freeze for fix ups and another two weeks after that for a 0 day update if warranted.

First 3.17 merge window kernel
by Josh Boyer 12 Aug '14

12 Aug '14

Hi All, I just kicked off the first 3.17 merge window kernel build on koji. I've tested it locally here on a few machines and haven't noticed any significant issues. If you feel so inclined, please grab it from koji when it completes and try it out. Let us know how it's working. If for some reason it's broken on a significant number of machines, I can try untagging it before it his the rawhide repo tomorrow. josh
