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 05 Jun '15

05 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

3.17 for F21
by Josh Boyer 06 Oct '14

06 Oct '14

Hi All, Since everyone likes to keep asking, we're going to be moving F21 to 3.17 when it's released [1]. There is ample time before Beta to shake bugs out and sticking with 3.16 until GA would simply mean we're shipping a kernel that likely won't be supported at the time of release [2]. josh [1] Linus was originally hoping to release it this weekend, but I believe a 3.17-rc7 will come out instead. We'll rebase when the final release is done. [2] We may still run this risk, depending on slips and such but at least we'll be as current as possible. p.s. F20 will get a rebase likely around 3.17.1 or 3.17.2. Be patient or upgrade to F21. F19 is in zombie state and will track the 3.14.y longterm kernels until EOL (which can't come soon enough).

Building a kernel with a patch
by Biggus Gazus 22 Sep '14

22 Sep '14

Hi list, Hopefully this is the place to ask, I've tried to follow this, so far so good ... https://fedoraproject.org/wiki/Building_a_custom_kernel I added these lines to my spec file, following the guide ... Patch74912: scarlett.patch ApplyPatch scarlett.patch At the end of their respective sections. I try to build the RPM, and I get ... ERROR: Patch scarlett.patch not listed as a source patch in specfile Somebody in the chat room suggested I might need a SOURCE line or something as well? But the guide doesn't say that. Any clues? Cheers! Gaz

F21 milestone kernel versions
by Josh Boyer 05 Sep '14

05 Sep '14

Just so there's one place to point people: F21 Alpha: 3.16.y (likely 3.16.1 at this point, but depends on further slips) F21 Beta/RC/GA: Unknown. We'll revisit it once Alpha is out the door (because it depends on how many more times Alpha is going to slip, etc). josh
