[Make-wifi-fast] Airtime fairness patch merged upstream, and the Turris Omnia debloated

[Make-wifi-fast] Airtime fairness patch merged upstream, and the Turris Omnia debloated

[Toke Høiland-Jørgensen]

The airtime fairness patch for ath9k has been accepted into the mainline
Linux kernel, and is queued to be merged for 4.11 (i.e. the next merge
window after the current 4.10 cycle completes).

The patch has also been accepted into LEDE and is currently in Felix'
staging tree at
https://git.lede-project.org/?p=lede/nbd/staging.git;a=summary - so if
nothing surprising shows up, it should make it into the regular LEDE
nightlies before too long :)


In related news, the Turris Omnia had the WiFi queue restructure patches
added in the latest update; and the ath10k chip it ships with seems to
have the required hardware support, so both WiFi devices in the Omnia
now have nicely debloated queues. They also switched to sqm-scripts
(from wondershaper that they shipped before), and added Cake :)

I note that jon just merged cobalt and made the sqm mode (diffserv3)
and triple-isolate the default.

Also, I've been testing the new cake code and thus far it doesn't
crash, at least, and appears to be giving the desired results.

It's escaped out of Felix's tree and is now in master.  Snapshots will 
start to have that as default as the buildbots do their thang.

Not a bad present really :-)

It looks like christmas morning would be a good time to open
presents... and flash firmware!

Also:

The latest cake is looking like a win across the board (see attached).
I am still nervous about longer RTTs (as I haven't tested those since
the cobalt branch was merged), and I figure there is more to be done
to speed it up - it's about cpu equivalent at 250Mbit on the apu2.

I need to dig out my WNDR3800 and see how cake and the airtime fairness
patches all perform on it vs the WRT1900AC.  But it's internal antennas and
11n radio have nothing on the WRT1900AC for wifi coverage and performance
(over 2x the throughput at medium range, 10x at longer ranges, in my house).

This is awesome news! This means that it will be included in the first
stable release that they have planned in the near future :)
Now the following question might sound stupid, but how difficult would it
be to apply these airtime fairness principles to Ath10k as well?
Is this planned? Or will this be a Ath9k feature only?

Hope so. I look forward to testing that build soon - today, even,
maybe, if I get unburied enough from christmas stuff.

The QCA folk have made noises about how to go about airtime fairness
there. I really don't know how it will work, but there seemed to be a
lot of enthusiasm in the room at the talk.

 I am hoping merely that the intermediate queues implementation (and
thus, fq_codel) works with my older ath10k hardware at some point.

Not clear to me if the ubntlite is capable of the "right thing", in
particular, or what ath10k hardware enables it or not. When I last
tried it I was at 100s of ms of added latency on that ath10k in that
box.

> Is this planned? Or will this be a Ath9k feature only?

Well, I have some hope for the mt76, one day (already intermediate
queue enabled), and we've looked over quite a few wifi chipsets.
Marvell, perhaps. Quantenna appears impossible with the state of the
firmware today. To me, up first would be a working intermediate queues
implementation for, say, a few wifi chipsets used in clients like the
c.h.i.p and pi3.

I *dream* of finding an android chipset worth hacking on.

I think Toke, Dave & myself regularly gently nudged Felix.  I know that 
I nudged for exactly the reason of 'it should go in the first release' 
simply to get it out there.

It's a similar story as to why I recently bumped the kmod-sched-cake 
package (twice)

It needs to be available for people to use...the next challenge is 
getting people to use it....at least ath9k airtime fairness will be the 
default.

Toke,

Do you know if it's made it into the LEDE nightlies, yet?  I loaded up the
Dec 22 nightly onto my WNDR3800.  Running rrul I'm getting about 10-30ms of
latency over wired on the same link (and wifi is definitely the limit, as
it's using piece_of_cake at 135M down, 12M up (and I'm seeing 0 measurable
additional latency from piece of cake).

I really don't recommend cake at much greater than 60Mbits on this
hardware inbound.

> additional latency from piece of cake).

rrul stresses out both sides of the wifi connection AND all the Qos queues.

rrul_be stresses out both sides but only one queue.

rrul remains generally awful on wifi unless your dscp markings have
been eliminated in transit.

for rrul_be - unless you've got the fq_codel code on both sides, you
aren't going to see as much benefit, and even if you are, the double
buffering on both sides leads to a typical latency of about 10ms each
way in this scenario. (so if you got it, you are inline with our
results).

I generally switched to using tcp_nup and tcp_ndown (with varying
numbers of flows), as well as the various rtt_fair_var tests against
multiple stations, to evaluate the wifi changes.

It's not clear to me if the quantum and codel targets were restored to
their defaults in this release (300->1514, 20ms -> 5ms)

I, however, am _very_ happy with the results at those levels (using piece
of cake, not layer-cake, layer-cake is flapping bandwidth between BK and
the rest in my tests).

And... my WRT running OpenWRT CC is using quantum 300, target 5ms.

Impressive.

I haven't gone and measured cake recently on low end routers. Certainly less
classes helps it. It would be good if this performance level is true
for the current
implementation with a single queue.

The actual target and quantum are in one of the sysfs aqm files, I believe.

Also I note most of the benefit of the new wifi code is at lower rates
from your AP. Try moving 20 or more feet away....

I did pay some attention to optimising the core algorithms recently.  I’m glad that seems to be paying off.

[Dave Taht]

The simplest way to verify if you have the airtime fairness stuff is
to look for a sysfs file named "airtime". The best way to test it is
to drive more than one wifi device over it simultaneously from a wired
link, and not through the ISP link.

flent -H device1 -H device2 -H device1 -H device2 rtt_fair_up # example

What is your wifi client presently?

and your rrul result I regard to be impossible unless wifi is not your
bottleneck or all your markings are getting washed away or you have
802.11e disabled (which I long have recommended disabling anyway).

Wired, 3800 running the latest LEDE snapshot, and the ac1900 running the
OpenWRT CC release.  They have _slightly_ different SQM settings, though:

3800:
LEDE 2016/12/22 snapshot
"piece of cake"
135Mbps down
12Mbps up
DSCP no squash, don't ignore on ingress
ECN

wrt1900ac:
OpenWRT Chaos Calmer rc2
simple.qos
160Mbps down
12Mbps up
DSCP no squash, allow on ingress
ECN

So I'm running a single-queue on the 3800, and multi-queue on the wrt.  The
WRT has always counted bytes in an "off" manner, limiting to _far_ below
the set level.  Unlimited on this modem is up at 180Mbps downstream today.

Today's tests with LEDE on the 3800 were a warm-up for moving the wrt1900ac
over to LEDE.  But I wanted a backup in case something goes awry (nearly
bricked the 3800 as I forgot to uncheck "keep settings" on the
OpenWRT->LEDE upgrade.

At short range, the wrt1900ac running OpenWRT is still out-performing the
3800 running LEDE.  The wrt1900ac has some _very_ nice radios (or maybe
it's just the much better antennas).  I'll do longer-range tests tomorrow,
if I get a chance.

yep. there's also a per station one that only a parser could love. Example:

./kernel/debug/ieee80211/phy0/netdev:wlp2s0/stations/04:f0:21:1f:36:e2/airtime

I'm getting on a plane to florida in a few hours, but I'm packing a
ubntlite with me (as a gift for mom). Sounds like no more debugging
required....

It sounds like we are on the verge of breaking out the eggnog, and
raising a glass... (but I'd like a few more testers first - got a c7
anyone?)

A merry bloat-free christmas to all, and to all, a good firmware!

I'd like you to use tcp_ndown and tcp_nup for a fairer comparison than
rrul, with 1,2,3,8,12 streams... but I am quite happy with all this so
far. Looks great.

At distance I have generally found the higher tx power available helps
on the higher channels, btw. I can't remember right now, but 153 and
higher could do like txpower 30, and are less commonly used.

I tried higher power early on with the wrt1900ac, but it seemed to cause
problems, although I don't think I was on that high of a channel.

Re: [Make-wifi-fast] [Cake] Airtime fairness patch merged upstream, and the Turris Omnia debloated

[Dave Taht]

Heh. Of all the hackerboards I tried, the odroid c2 was the fastest
and is generally my default target these days.

The "chip" is coming along nicely but lacks network.

The odroid c1 and rpi2 have been the most reliable.

(I'm still looking for a board with a decent toslink port....)

...

I just foolishly tried to update my linksys 1200ac, but... it turned
out the cable modem behind it was acting up and I lost touch with it
(lacking a babel pre-installed)... aha! (/me worms his way through
multiple hops through another modem)

It looks like my default command line, post install is basically:

opkg install luci-ssl luci-app-sqm babeld kmod-sched-cake netperf

The 1200ac still has bug

https://bugs.lede-project.org/index.php?do=details&task_id=294&order=status&sort=asc&order2=severity&sort2=desc

I triggered it with:

root@apu2:~/t# flent -H 172.26.64.1 -t 'isitfixed'
--te=download_streams=12 tcp_ndown

Warning: Program exited non-zero (1).

Standard error output:

The way I was dealing with it was with running cake at 900mbit on the
internal ethernet. I guess it's one way around bugs like this.

I just installed the dec 25th build for the ubnt uaplite.

airtime fairness/fq_codel appears in there for the ath9k.

regrettably the ath10k in that box is not picking up the fq_codel code.
Too old firmware? Too old chipset?

It probably does not have the ath10k softqueues patch from Toke's
