fedora 14 kernel performance with ip forwarding workload
by Jesse Brandeburg
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?

Remove ppc32 support
by Josh Boyer
The powerpc secondary arch team has disabled all ppc32 builds in koji for
F21 and beyond:
https://lists.fedoraproject.org/pipermail/ppc/2014-May/002801.html
There's little point in keeping support for ppc32 support in the kernel
package when it will never be built. This also removes the -smp variant
and with_smp* support, as that was only used on ppc32.

Would building netconsole in for debug kernels make sense?
by Bruno Wolff III
If netconsole is built as a module, you can't use it to capture output
before the module gets loaded. Rebuilding Fedora srpms (to get Fedora
patches) takes pretty long, which makes testing slow.
I have something particular I am testing now (probably a nouveau related
crash) that crashes for netconsole gets loaded (though I tried to add
it to the initramfs to get it loaded fairly early). I am not sure if it
will be early enough even if it is built in. I won't know until sometime
tomorrow. But if it does get loaded early enough to handle video card
related stuff, it seems like it be worth having built into debug kernels.

systemd-214-5.fc21.x86_64
kernel-3.16.0-0.rc3.git0.1.fc21.x86_64
It seems this kernel? bug is still present[2].
"rd.vconsole.font=ter-v32b" also fails to subsist due to
"fb: switching to nouveaufb from VESA VGA".
- journal systemd-vconsole-setup
systemd[1]: Starting Setup Virtual Console...
systemd-vconsole-setup[347]: putfont: KDFONTOP: Invalid argument
systemd-vconsole-setup[347]: /usr/bin/setfont failed with error code 71.
systemd[1]: Started Setup Virtual Console.
I've found so far that this can only be overcome with these two almost identical solutions;
When I thought of 'actual-vconsole-setup-start' I did not know that Yegor already done it.
Saṃsāra.
Yegor's solution[1]:
# cp /usr/lib/systemd/system/systemd-vconsole-setup.service /etc/systemd/system/
# diff /etc/systemd/system/systemd-vconsole-setup.service \
> /usr/lib/systemd/system/systemd-vconsole-setup.service
13,14c13,14
< After=sysinit.target
< Before=shutdown.target
---
> After=systemd-readahead-collect.service systemd-readahead-replay.service
> Before=sysinit.target shutdown.target
or even simpler - leave 'systemd-vconsole-setup.service' as is,
and make this one
/etc/systemd/system/actual-vconsole-setup-start.service:
# Actual Virtual Console Setup Start
[Unit]
Description=Actual Virtual Console Setup Start
[Service]
Type=forking
ExecStart=/usr/lib/systemd/systemd-vconsole-setup
[Install]
WantedBy=rescue.target multi-user.target
# systemctl enable actual-vconsole-setup-start.service
and now you have appropriate font size for 1920x1080,
no need to lower resolution via "video=<xres>x<yres>".
Perhaps '32' is too large, so choose <= '28', e.g. ter-v28b or ter-v24b.

[PATCH F19 F20 Rawhide] Revert "Input: wacom - testing result shows get_report is unnecessary."
by Benjamin Tissoires
This reverts commit 1b2faaf7e219fc2905d75afcd4c815e5d39eda80.
The Intuos4 series presents a bug in which it hangs if it receives
a set feature command while switching to the enhanced mode.
This bug is triggered when plugging an Intuos 4 while having
a gnome user session up and running.

Hi,
This patch is on its way upstream (it has been submitted to the list):
http://www.spinics.net/lists/linux-input/msg31843.html
I already received a complain from Bastien that his Wacom was broken in F20,
so having this in F20 and rawhide would help the Intuos 4 users.
The regression has been introduced in the kernel v3.12, so F19, F20 and rawhide
are impacted.
Cheers,
Benjamin

Thanks for info.
Yeah, as Lubomir stated "vdso=0" works with broken ones,
and
3.16.0-0.rc2.git0.3.fc21.i686 PASSED
BTW, Adam, there are people running & testing Rawhide on i686! :)

No 3.15.1 kernel builds are getting scarce
by poma
I was expecting to see 3.15.1 kernel show up with stable status in Fedora 20.
But we haven't had one show up yet.
We may need it for new features in it, since 3.14.x missing some of them.
It is nice to have the 3.15.x for day to day use.
