I ran some short tests with 100M mode enabled (connected to GbE router) (GbE test was taking sooo long and i needed to know if the script was running) and see if TX/RX would change/improve on this mode.

The odd thing is that if i run the same test more than once i get different values, take an example 1/25, it is so bad in one run and the next one is almost normal, just make me wonder there is something else involved.

 

Do you get very different values on your tests?

 

I will let the GbE test running this weekend.

Do you get very different values on your tests?

 

Absolutely. Four things to mention: 

  • The board you're testing with is broken, TX/RX delay shouldn't influence Fast Ethernet (as far as I understood). Such variations in 100 Mbits/sec mode is a clear sign that there's something really wrong. I would assume you cleaned contacts already, exchanged cables and switch port?
  • This '979' value you report is most probably Kbits/sec. My script sucks a lot since it assumes iperf3 output being printed in Mbits/sec. But in such cases as yours where really something goes horribly wrong this is wrong. Anyway: based on your results you can already stop, there's nothing to improve/test
  • Xunlong's BSP kernel for OPi PC 2 seems to not make any use of tx-delay/rx-delay set in DT, maybe they currently use a crude mixture of sys_config.fex and .dts but at least my test results show identical results iterating through all 256 combinations (0-7 TX, 0-31 RX). In other words: it's currently a waste of time to try to tweak Ethernet settings for OPi PC 2 unless this is resolved
  • With my 2GB Pine64+ it looks like this: As soon as rx-delay is above 4 then no Ethernet connection is possible any more (see below). Test will last a few hours so I'll update then the results in OPi PC 2 github repo issue

Empty entries means: No connection between client and server possible at all. I had a laugh before since I thought it would be a great idea to test this with as many Pine64+ as possible. I then realized that Pine people sent me 7 Pine64+ samples, the first maybe still stuck in customs, the 2nd one bent to death, N° 3 at Zador's desk, N° 5 at jernej's desk, N° 4 and 6 sent out to @androsch (who helped nailing down the Pine64 GbE issue). But @androsch was so kind and sent me N°4 back so I can at least test with one other Pine64+ tomorrow.

Where do i place this script to test my boards?

Sorry, did not check first, its already mentioned in the script itself....

Will do some checks tomorrow.

Great! Just a few notes. It can be pretty annoying when things go wrong (the script tries to test something and initiates a reboot automatically, 8*32 times in worst case scenario). So I hope you've another Linux box and an SD card reader to remove the execution of the script in /etc/rc.local if this happens.

 

Then longsleep's default settings are 3/0 (TX/RX delay). First step is therefore to create a .dts and adjust there tx-delay to be '<0x0>;' (must exactly look like the rx-delay value):

dtc -I dts -O dtb -o /boot/pine64-plus.dtb /boot/new.dts

And then those paths have to be adjusted and of course on another GbE capable host iperf3 on port 6000 has to be started. Script version suitable for Armbian on Pine64+:

Sorry, does not make sense to check out other values, because the board only works in GbE-mode with longsleeps gmac-kernel, with normal kernel GbE is still unusable.

 

gmac-kernel with network-script.sh and performance governor including a 5V/3A PSU allows about 500mbits now, so this is fine for me.

Which board are you talking about? The one i sent to you with '2' written on the Ethernet jack? This one worked for me without any problem using the unpatched kernel and exceeding 900 Mbits/sec in both directions.

Of course not, this is a board you already used for testing, so it makes no sense from my point of view, i tried to test the other board i received from tllim (same revision and version like your board btw) but this does not work with any other than longsleeps gmac-kernel in GbE-mode. I even just exchanged the two boards with their PSU, SD card and cable to the switch and they show the same results.

 

I get about 500 mbits now with the 'bad' board, so for me this is fine now....

Ah, ok. Sorry, but I really don't care about these 'bad' boards. Pine64 users should make some noise to get their broken hardware replaced/refunded. The aforementioned test was meant to be used on working boards. I'll fine tune the script slightly (since testing RX delay values between 8 and 31 is a waste of time) and post a new version later :)

I don't really see 500mbit cap an issue on this board. At the end of the day, you're still limited by other IO (USB 2.0 for one) so having a full blown gigabit ethernet on a board like this is pretty pointless, unless you also have usb3 or native sata to play with.

Yes, thats the reason why its ok for me now, 500mbits exceed the about 20mb of usb2, so this is fine, at least for me

20mb of usb2

 

Huh? This is Allwinner country, here we speak UASP ;)

 

Really: 500 Mbits/sec == defective. We can use ZFS on our boards with active lz4 compression (or btrfs/lzo with mainline kernel) and easily exceed 50MB/s with average data regarding disk IO. Also when things are set up correctly especially on the 2GB Pine64+ the write speed to the board can be as high as 80 MB/s even if there's just slow USB2.0 storage behind: Since data (up to 1.5GB in size) will get buffered in memory and flushed to disk later.

 

Next problem: With such a defective board (or inappropriate settings) you can easily end up with one CPU core 100% busy serving Ethernet IRQs. If you now happen to run your application on the same core then you are already limited to 500 Mbits/sec max on the wire but in reality overall throughput will be way below since application and IRQ handling fight for CPU ressources.

 

There's not much interesting on Pine64 or A64 in general (for my use cases). The only real plus is the ability to easily exceed 900 Mbits/sec GbE throughput in both directions.

You are surely right as far as i know your knowledge here, but i only use this certain board as minecraft server for my son and his friends (even via remote login), so the slowest part is the SD card or even my internet connection :-)

The out of control moderator just banned me.

 

Yesterday he had also a great day, banned one account, censored a whole thread away and in two other threads important information:

  • here he deleted the last post mentioning that there's now also an Armbian Desktop image available (beta)
  • And in this thread he deleted posts containing the following information:
  • Firefox works without any problems on Armbian, that's simply since we install the armhf version by default on the desktop image since the arm64 version shows problems (this 'trick' can of course also be used to cure even the most crappy OS images for Pine64: on the broken Debian images from Pine wiki it's just 'apt-get purge firefox && apt-get install firefox:armhf' and those steps in between)
  • Chromium with our Armbian desktop image is just a simple 'apt-get install chromium', there's really no need to install .deb packages from linaro or somewhere else.
  • Using Chromium with '--disable-seccomp-filter-sandbox' is a bad idea, it would be better to address the problem (kernel fix needed?)
  • If one wants to use '--disable-seccomp-filter-sandbox' though this can be added to all 'Exec' occurences in /usr/share/applications/chromium-browser.desktop

So he managed to make Pain64 land great again, instead of informing people that there is software available that doesn't suck they (Pine Inc folks and their beloved premium moderator) ensure that no one knows, that people still use outdated, smelly and broken OS images containing numerous serious flaws and that nothing will change. Users are not informed that there are working 3rd party OS images existent in the meantime and users aren't tought how to use Firefox if they want since one person is allowed what he does best all the time: censoring everything he doesn't understand.

It might work just fine with Armbian (I haven't tried it myself as I haven't run the desktop beta - my intended use for the pine was always headless server stuff - but I believe you anyway) - but it will NOT work with the debian images for the pine64 (without using external repos, etc) - and it has nothing to do with them being crappy either - it's the clash between Mozilla's distribution requirements and Debian policies that were fault there. Debian Jessie does not, and has never shipped with firefox in it's repo. Starting with Debian Stretch, it will be available, and in the meantime, the extended support release of firefox was backported to Debian Jessie as firefox-esr.  Now, that is an issue - as the  firefox-esr:arm64 appears to be broken for the pine64, and the firefox-esr:armhf package won't install without some serious massaging. Or being stubborn, ignoring the whole "old is good as is stable philosophy of debian" and jump onto the unstable bandwagon... ;)

 

It's because of things like this I generally say... yeah, there's a workaround/bandaid, or you can go install Armbian and not look back! ;-)

Pinebook announced: https://www.pine64.org/?page_id=3707

 

Armbian support can be added easily since it's just different DRAM type and two different screen resolutions (hopefully we're able to distinguish between them prior to loading kernel): http://www.cnx-software.com/2016/11/24/pinebook-arm-linux-laptop-powered-by-allwinner-a64-processor-to-sell-for-89-and-up/#comment-536419

 

Edit: Both screen sizes use the same laughable 1280x720 1376x768. So in case displays are compatible a single set of settings (DRAM, LCD settings) is ok for both variants. I'm assuming that trackpad drivers are already available in BSP or will be provided soon.

I might look at the Olimex one instead... especially because it can run windows(kidding!!!)... or more importantly seems to have some more sensible resolutions... 1376x768 and 1920x1080. I suppose this one should be interesting... at least there won't be a GbE issue this time as they fixed it by removing the ethernet! :-P So was that the hardware problems fixed... just the minor detail of crappy software?

What's the latter resolution? I thought they only want to go with 1366x768 (LVDS --> eDP)?

 

Anyway: Maybe you could do the micro community over there a favour and post http://web.archive.org/save/_embed/http://bundie.neterra.net:8080/a64/A64%20LCD使用说明书.pdf to the LCD subforum? So tinkerers who want to exceed the 800x480 currently know where to adjust values...

I decided to test USB/UAS performance with Pine64+ now that we can use USB with mainline kernel. I chose the Xenial/vanilla Armbian image I built yesterday with A64 cores running with 864 MHz, an ASM1153 enclosure with a Samsung EVO 750 inside, btrfs without compression as test fs and let these three commands run:

iozone -e -I -a -s 100M -r 1k -r 2k -r 4k -r 16k -r 512k -r 1024k -r 16384k -i 0 -i 1 -i 2
iozone -a -g 4000m -s 4000m -i 0 -i 1 -r 4K -r 1024K
iozone -O -i 0 -i 1 -i 2 -e -+n -r 4K -s 2000m

The first test line is the one known from our SD card tests, the next two (using a large 2 or 4 GB testfile size to minimize caching/buffer effects) from the USB/UAS link above. With just 100 MB test data size some numbers are obviously wrong (way too high so buffers were tested and not the device).

 

But test results are simply excellent given that we're talking about USB 2.0 here since UAS is a lot more efficient than the old USB Mass Storage mode normally used with USB 2.0 (using Allwinner SoCs here is a real advantage since they speak UAS even with USB 2.0). Sequential write/read speeds exceed 41 and 42 MB/s and random IO is also quite nice -- to be able to compare search for 'EVO 750' numbers in this thread here (and please read a bit through to get a deeper understanding how to interpret these numbers).

 

Funny is that regarding random IO A64 with UASP easily outperforms the older A20 with SATA. Banana Pro (A20/SATA) vs. Pine64+ (A64/USB2.0):

                  Random IO in IOPS           Sequential IO in MB/S
                 SATA           USB2           SATA            USB2
            4K read/write  4K read/write   1M read/write   1M read/write
  A20         2779/893       1277/619        106 / 39         34 / 35
  A64           - / -        5033/6033         - / -          42 / 41

To sum it up: A64 outperforms A20 everywhere except of sequential read speeds (A20's SATA interface is able to exceed 200 MB/s -- the 106 MB/s above are the result of Samsung's EVO 750 not being that fast here). To be fair: measuring random IO with 4K blocksize means also tampering random IO with sequential bottlenecks -- but I'm just too lazy to repeat tests with 1K. But since in real world situations it's exactly the same why bother.

 

All results:

Conclusion: Time to overthink 'SATA is better' platitudes at least when we're talking about aging A10/A20 here. A64 performs pretty well here and I would assume the same will be true for H5 (there we get 4 real USB ports unlike 2 with Pine64 now -- but with A64 one of the ports can be switched between OTG and a real USB host port using an own PHY while H5's OTG port seems not to be switchable. If performance is close to H3 this isn't that much of a problem since OTG port there in host mode is just slightly slower compared to real host ports)
 
EDIT: I ran the same set of test with 3 different setups: H3 board using USB2/UAS, A20 board using USB2/UAS and same A20 board (and same SSD of course) using SATA (kernel 4.8.11 with A20, 4.9 with H3):
 
Tested were the same 3 iozone calls:

Don't know how they're doing it... I read that from their exceptionally detailed(!) product page... https://www.olimex.com/Products/DIY%20Laptop/

 

Wildo... ;)

 

re: test results... so why wouldn't it be better using a H5 be better than the pine64 since you could stack up three native USB ports instead of 2 (when the OTG port is switched)? And still do something with the 4th?  :lol:

 

 

What's the latter resolution? I thought they only want to go with 1366x768 (LVDS --> eDP)?

 

Anyway: Maybe you could do the micro community over there a favour and post http://web.archive.org/save/_embed/http://bundie.neterra.net:8080/a64/A64%20LCD使用说明书.pdf to the LCD subforum? So tinkerers who want to exceed the 800x480 currently know where to adjust values...

lol... oops! the pine64 forum... er... the whole shebang... is now offline... looks like the pinebook is getting a little too much interest... and TL said the IT guys were all over it! :-O

 

"It's not just you! http://forum.pine64.orglooks down from here."

 

@hojnikb... true, but if you were running it with wanting that sort of throughput... I'd be worried about the batteries being able to do much more than short-term UPS work... as they'd have to carry the load of the pine64 and the attached hard drives (unless using externally powered drives, at which point why bother having a battery on the pine64?). I was thinking more of the ability to shove ~40MB x 3 through to the GbE... yup... think we found the next bottleneck! :D

Isn't gigabit issue fixed now ?

GBit issue on what board?

Pine64? It's a hardware issue and the best way to fix this is replacing the board.

PC2? I don't remember any issues there, but as soon as we get test images we need to collect enough statistics data to adjust TX/RX delays to improve GBit performance.

 

And what about mali, don't we need blobs for that ?

We need to get DRM display driver and Mali kernel driver first (at least for using mali with X desktop).

Using a patch to force 100 MBit/sec since TX/RX delay currently can't be adjusted the 'usual way' IMO isn't a solution to be honest (of course it would be one for Pine64's Android offers since Android users seem to be happy to better use stable Fast Ethernet than broken GBit Ethernet -- but TL Lim and Pine people are simply too ignorant to even think about improvements at all)
