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

Toshiba backlight patch for Fedora kernels
by Hans de Goede 30 Apr '15

30 Apr '15

Hi Josh, I've a patch for the Toshiba ACPI kernel driver fixing backlight issues on various models, it fixes these 2 bugs: https://bugzilla.redhat.com/show_bug.cgi?id=1206036 https://bugzilla.redhat.com/show_bug.cgi?id=1215989 Which are a regression starting with 3.19, since we got 2 bugs in a short time this likely affects more users. The fix for this got merged recently: https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/driv… I think it would be good to apply this to the Fedora 4.0 / 3.19 kernels, I've attached a version for those (resolves a 1 line conflict in the #includes). I say I think because although it looks like this patch will fix issues on various models, it may also introduce issues on other models which is why I've not added a Cc: stable for upstream. Still overall I think we should apply this. Regards, Hans

4.0 final, 4.1 merge window, and us
by Josh Boyer 17 Apr '15

17 Apr '15

Hi All, The 4.0 final release is in rawhide and submitted for an update for Fedora 22 now. Given the release schedules for 4.1 and F22, we're going to stick with 4.0 for F22 GA. Please stick to fixes for F22 and we'll no longer keep that branch in sync with rawhide. The 4.1 merge window is open and active upstream as well. I'll be rebasing rawhide to those kernels likely later today or tomorrow. If you have things that are landing in 4.1 that you'd like enabled, please let us know. The only major feature I'm aware of that might land is kdbus, but the jury is still out on that one. Thanks. josh

RFE: Enable CONFIG_R8188EU (from staging) in Fedora (ARM) kernels

Hi, The usb wifi modules supported by CONFIG_R8188EU (from staging) are used on quite a few Allwinner ARM boards which we now support, can the (staging) driver for these be enabled please? If not in general, then at least for ARM? Thanks & Regards, Hans
