Hi Drag00n and Patrick,
I will email the latest boot.img (with Gbit Ethernet working) to both of you tomorrow. If other folks interest, we can post at Wiki page. Regards, TL Lim

You'll need more than this boot.img file to get Gb ethernet working. I had to program the whole android image with phoenixcard and reload ubuntu onto the first partition to get the Gb ethernet working with linux; overwriting just the boot.img wasn't enough. Probably a DTB and/or FEX change in addition to the kernel update.
Anyway, here are preliminary numbers on the Gb ethernet throughput. The Pine64 board was hardwired to a 4-core, 2GHz Intel Core i7 laptop running Ubuntu 14.04.3 with a Realtek RTL8169 NIC. Tests were performed with iperf on quiescent systems: 1 thread 4 threads inbound 880Mb/sec 940Mb/sec outbound 400Mb/sec 850Mb/sec These numbers are quite good for an ARM SoC. The FreeScale iMX6 line maxes out at around 1/2 these values (due to a bug in the chip itself), and the Cubietruck (Allwinner A20) runs at around 500-600Mb/sec. Edit: changed above values from Gb to Mb (oops!) 
@TL Lim will you release the changes AS source? Best would be a pull request to https://github.com/longsleep/linux-pine6...ne64-hacks :-)
Thanks, Simon

The network performance there really needs a boost. Using the binary only kernel isn't a practical option. I managed to get Docker support into this kernel and I'm in contact with Kai Kreuzer discussing the best way how to integrate OpenHAB. Cheers, Uli |
