The rest of that thread was not particularly encouraging.

I don't have at 1900AC. I do have the netgear X4 sitting on a shelf
awaiting better support.

as the sqm-scripts work well on even the lowest end modern x86 system,
I will argue that what is needed is mostly larger caches on the arms.
Over the holidays I snagged a bunch of arm based platforms to (I'd
hoped) more easily test (with decent flash and memory)

xgene: boots, the root password is not published, then the serial port
went flaky
u-droid U1: got two, both boot, get an IP, then crash 3 seconds later, no logs
                 even though there are 4 A5 cores, SMP support doesn't
work yet in linux
u-droid U3: doesn't even boot
radxa rock-lite (Seems to need uboot and linux flashed from a special utility)
(the rock2 seemed promising)

My enthusiasm for hacking on teeny little boxes was subsequently
dimmed, and I went back to wrestling with vivado and the paralllelas.

If anybody in the bay area wants to try to bring up any of these boxes
to usefulness,
I will gladly make christmas presents of them and hand deliver.
