[Cerowrt-devel] Current status and recommendations for APU2C*/ArcherC7 and ath10k platforms?

Apologies I haven't had time to follow recent developments but are there
 any recent bufferbloat/CAKE related news/recommendations for the APU2
platform? Specifically the APU2C (previous was marvell I believe)

Hardware:
APU2C4 (AMD x86_64 | 4GB | 3x i210-AT)
WLE600VX (ath10k)
64GB mSATA

Also have an Archer C7 V2 (ath10k) and a old WDR3800 (ath9k) still
chugging along.

Looking for an optimal Archer C7 build or recommendations if anyone
has any experience on it.

Use case:
linespeed: 105/120 fiber -> APU2C4 primary gateway (and some WiFi) ->
Archer C7 & WNDR3800 for internal & guest networks
(undecided which of the last two for each task). My plan is to use
separate networks for bulk traffic others for latency sensitive stuff.

Anyways I searched through mailing lists and google but thought this
might be the best place(s) to ask.
I noticed dtaht is (or was) using an APU2 (though not sure which version
 of it since one of his posts refers to mvneta, the marvell platform).
Also saw that Dave's tc-adv didn't make it upstream?


From what I gathered, I found these relevant but perhaps outdated:

http://blog.cerowrt.org/post/birthday_problem/
<http://blog.cerowrt.org/post/birthday_problem/>
(refers to APU2 and it's 4 hardware queues but was this marvell/mvneta?)

https://github.com/riptidewave93/LEDE-APU2
(Older github repo for APU2 LEDE support but seems upstream now?)

https://github.com/Gr4ffy/LEDE-APU2
(older fork from above riptidewave93 LEDE-APU2)

https://github.com/greearb/lede-source-ct
(ath10k related; LEDE fork from Candela in which they apparently
obtained the ath10k firmware source code NDA)

https://github.com/dtaht/sch_cake/issues/46
(Fairness issue and a reference to dthat's custom tc not going upstream)

[multiple mailing list links]
(References to airtime-fairness? is  this primarily for ath9k?)

[APU2 ubuntu repo link I lost]
Saw a repo for dtaht's ubuntu build for APU2 somewhere?!? Or was it
under another name? If anyone knows the URL I'd love to borrow some
of the settings for testing.

https://github.com/pcengines/coreboot
https://github.com/pcengines/seabios
(APU2 related, they seem to still update their bios but they don't
release much.
I also saw some commits referring to ECC support on APU3, I guess ECC on
 the APU2 is a lost cause)


Any other more appropriate lists or IRC channels I might inquire in would
also
 be helpful.


P.S. My condolences for the loss of your lab @ Dave, that truly is a
travesty.

Thanks

The 17.01 LEDE release is great for both the C7 and the WNDR3800, and
has all the WiFi-related fixes (bufferbloat fixes and airtime fairness)
included. You'll probably need something beefier for a main gateway at
those speeds, though. Not sure about the APU2; think it is supported in
LEDE as well?

I have generally abandoned the "all in one" home router architecture -
my edge gateways are apu2s (now running the lede final release - with
perfect uptime thus far),

and the interior wifi box is generally a centrally located ubnt-lite.

I have a small problem in that my apt gets 1.5gbit down these days,
and only the apu can keep up.  (the ath9ks in the apu work pretty
decently, but it's at the far edge of the building next to the fiber
backhaul), thus a separate wifi box.

...

I now can say some very nice things about the linksys ac2600 - and the
edgerouter X as well - after a month of testing the lede final, I just
deployed those as the main wifi unit, and main interconnect between the
yurtlab and the campus. Got rid of a whole slew of cables (it used to be
3 wndr3800s connected to the wifi uplink, backup wired line and main
wired link). The edgerouter X is doing POE for the wifi mesh.

...

I realize that my setups no longer resemble anything normal, and I think
the archer c7v2 is still a very good box, particularly with 2ghz.

The ac2600 does not have the make-wifi-fast fixes in it - and has tons
of latency in the 2ghz radio... but I'm all 5ghz now and only have to
drive it 20 feet, and tons faster than the archer.

I'm in the middle of unplugging, reflashing and rotating out all the
previous era wndr3800 gear.
