is it possible to hack any h3-based sbc, e.g., opi +2e, so that i can get better than usb 2 speed to a connected external drive? for example, is there any kind of hack to wire directly in to the pci-e bus? (i know that seems like such a long shot it might even sound silly, but you never know...)
<diego71>
h3 does not have pci support so I suppose not
<diego71>
may be you can have 2 usb hd in raid...

diego71: wdym by "2 usb hd in raid"? as in, 2x usb drives striped in raid 0?
<diego71>
yes

<diego71>
but only if the two usb port don't share some internal bus that slow down accesses
<ullbeking>
It's a good thought but I don't think it'll be enough
<Ashleee>
gotta use soemthing better :)
<Ashleee>
you can get rk3399 -based SoCs with PCIe... RockPro64, Orange Pi 4 etc
<Ashleee>
and with either SATA or NVMe drives
<ullbeking>
Ashleee: I think you're right
<Ashleee>
Allwinner H6 has PCIe but last time I checked the driver was still not working as AW goofed up something in the design
<Ashleee>
(non-linear addressing IIRC)
<ullbeking>
ideally i need two nic's too
<Ashleee>
hmm you're stretching it :)
<buZz>
you could put a PCIe bridge on the bus
apritzel has joined #linux-sunxi
<buZz>
to get more devices onto it, they'll share bandwidth though
<ullbeking>
yeah, i'm getting into proper mini-itx board zone here ;-)
<Ashleee>
or throw the USB HDDs on USB3 ports
<Ashleee>
and PCIe NIC
<Ashleee>
or vice versa if you want NVMe :)
<ullbeking>
not many allwinner based options huh
<Ashleee>
if you want PCIe then not really
<Ashleee>
rk3399 has mainline PCIe working fine
<Ashleee>
and USB3 and all that stuff
<Ashleee>
and packs something better than Cortex A53 :D
<ullbeking>
which rk3399 sbc do you like?
<Ashleee>
I have only OPi4 ... and was sent two chinese H96 Max TV boxes to hack to run Linux instead of Android
<Ashleee>
but I use it just because CPU performance
<ullbeking>
is there a list of rk3399 based sbc's?
<Ashleee>
I have a large stack of 10x Pine64 (Allwinner A64), 4x Tanix TX6 (Allwinner H6), Orange Pi Zero (AW H2), 2x OPi PC (AW H3), RPi 3b, 2x Odroid C1, OPi 4 and 2x the H96 Max
<Ashleee>
(oh and I have one fully loaded SOpine Clusterboard as well... I keep forgetting about that, that's 7 more AW A64 SoCs)
<ullbeking>
Pine64 looks good to me too
<Ashleee>
Pine64 doesn't have PCIe nor USB3
<Ashleee>
I bought it back when kickstarter happened :) and then a bunch more boards

basically, i'm looking for something powerful enough that i can either add an extra NIC for a total of 2 NIC's, or use VLAN's for 2 VNIC's. i also need two interfaces to ssd's that are "fast", i.e., better than usb 2. that is, either usb 3 or a real SATA controller.
<mru>
allwinner might not be the right choice for you
<ullbeking>
it was a great choice for the things i used it for, but i think i've surpassed it
<ullbeking>
do you know any sbc's that have 2 nic's?
gaston1980 has quit [Quit: Konversation terminated!]
<mru>
you probably need to look at TI or NXP for that
<ullbeking>
and a real sata interface or usb3?
<ullbeking>
also, does there exist an sd card that can be used written and read from heavily like a real ssd?
<ullbeking>
KotCzarny: i'm after something a bit smaller and more "sbc-like" because i want to build a ceph cluster of hyperconverged storage. for my "home server" server i've got something else in mind.
<KotCzarny>
you still have to put the drives somewhere, which means sbc form factor doesnt matter much
<ullbeking>
sure

<KotCzarny>
should be ~50-100usd

apritzel: this is awful. I was looking at the h616 bl31 hoping there was a better way to turn off the CPU than yolo'ing the power switch... and I found this instead: https://pastebin.com/raw/Bg5kF0ux
<smaeul>
their sunxi_affinst_off is a no-op, and they're relying on Linux polling PSCI_AFFINITY_INFO from another CPU
<smaeul>
there's not even a check to see if the PSCI power state for the CPU is "off". any PSCI_AFFINITY_INFO call will kill the CPU

on the other hand, there is hardware-assisted cpuidle, which appears to do effectively the same thing as turning the CPU off, so I'll see if I can get that to work

KotCzarny: haha, actually I just realized some real irony ;-) trying to implement my solution using SBC's is actually really expensive, but using "real" mainboards gives me everything I need and more, and is actually cheaper ;-)
<KotCzarny>
glad you see the truth now
<KotCzarny>
sbc are special purpose thingies

the G2 mainboard can be found for about 40-50 GBP. i intend to stack them with [what are those brass spacers called that match the

smaeul: I thought the U-Boot sunxi v7 PSCI trick is somewhat horrible already: do a (secure) IPI to the *other* core to pull the plug from the calling core
