<tuxd3v>
your url with therman driver patch and the one you showed me in the mailing lists
<tuxd3v>
both work..
<tuxd3v>
But before with 5,4,2 kernel that was not true..
<tuxd3v>
something was backported.. to 5.4.X series :)
<tuxd3v>
19 december was when the patch was sent..
<tuxd3v>
I believe
<tuxd3v>
I am testing on H6 Orange one plus..
<tuxd3v>
and it seems to work out of the box..
<tuxd3v>
I mean..aplying the mailing list patch series..
<tuxd3v>
:)
<tuxd3v>
so good so far

ullbeking, I have one and it's a very nice little board. Noticably faster than H5 boards.
<tuxd3v>
ullbeking, yeah it is :)
<tuxd3v>
but its not the best supported and H6 doesn't have the ideal support in mainline, but that is also truth to others..
<ullbeking>
willmore: tuxd3v: it seems like a no-brainer for me, i just get one!!
<ullbeking>
the lack of full support is fine, i use h3 boards when i need support
<willmore>
Do. It's reasonably well supported and moving faster towards mainline than the H5 seems to be.
<ullbeking>
werid
<tuxd3v>
yeah I hope support improves, but you guys are right, for the price, you get a very nice board!
popolon has quit [Quit: WeeChat 2.7]
<tuxd3v>
I own one, and for me, its the best 4-core cpu board for the price
<tuxd3v>
it has a very good cortex-a53 that performs very well
* ullbeking
goes to aliexpress to place an order, and also to purchase a couple 3A upgrades to his existing 2A mains-driven PSU's
<ullbeking>
tuxd3v: what are you running on it?
<ullbeking>
as in...
<ullbeking>
what are your use cases?
<ullbeking>
here, for me...
* willmore
uses an old ATX power supply.
<willmore>
I feed lots of boards.
<tuxd3v>
I use it mainly to software compilation
<tuxd3v>
packages
* willmore
needs to build up his MC-1 when the holidays are over.
<tuxd3v>
I don't use it connected to a tv
<ullbeking>
i am quite focused on h3 still, and i have just built a 5-node opi +2e cluster, which i'm going to install docker and kubernetes on.... it's silent, beatiful, and the perfect home server
<willmore>
Yeah, all my boxes are headless. I only ever use a display when something goes wrong--or for initial setup for distros that are net-stupid.
<tuxd3v>
its nice to test on arm64, since its a 4 core cortex-a53
<willmore>
ullbeking, OT, but the recent sale on MC-1 solo boards was impossible for me to pass up. Four boards shipped from Korea for <$50 USD.
<ullbeking>
willmore: i'm trying to devise a solution, probably based on serial comms, so i can provision new machines without having to lug around a monitor, etc
<tuxd3v>
you can compile code for it and expect the code to run well in more powerful cpus
<ullbeking>
willmore: i never heard of MC-1....... checking it out now..... do u have a link plz?
<tuxd3v>
because some cpus are multi-cluster
<willmore>
ullbeking, I carry a 3.3v/5V serial<>USB converter around for that.
<ullbeking>
willmore: max232?
<tuxd3v>
and some times you get errors with software optimized for them
<ullbeking>
03:01 <willmore> ullbeking, I carry a 3.3v/5V serial<>USB converter around for that.
<ullbeking>
i have LOADS of these things
<willmore>
That's the individual board. Four of them make up a MC-1 (My Cluster 1)
<ullbeking>
HOLY MOLY
<tuxd3v>
this 2 cluster scheme its dificult to optimize since you need to build packages directly for that target..the same doesn't hapen on a 4 core cortex-a53 :)
<willmore>
They're octo core 4xA17 and 4xA7.
<willmore>
tuxd3v, optimize for the big cluster and just turn the little one off.
<ullbeking>
for the mc1, what are the standard cluster sizes as per the instructions and recommendations from hardkernel?
<willmore>
4xA17 at 2GHz is plenty. :)
<willmore>
ullbeking, not sure what you're asking. The MC-1 is made of four of the solo boards.
<ullbeking>
oh it's DEFINED as FOUR boards, oij
<ullbeking>
ok*
<willmore>
The heatsinks stack nicely and you bolt on a fan to the back. Then cable it as necessary.
<willmore>
4x GigE (5 port switch is perfect).
<willmore>
Power, etc.
<willmore>
Each has a USB2 as their sole I/O. These aren't dev boards after all. No Rpi type GPIO header.
<willmore>
There is the console serial port at 1.8V FWIW.
<willmore>
Sorry to go so far OT, but it's a good deal and ARM is ARM as far as a build cluster goes.
<ullbeking>
this is very welcome OT :-)
<willmore>
Still get that Opi One Plus.
DonkeyHotei has joined #linux-sunxi

BBL
<ullbeking>
i will have to order heatsinks, fan, cables, etc, separately?
<willmore>
The board comes with the HS. You'd need all the rest.
<willmore>
But the fan and power connectors are standard sizes.
<willmore>
Networking is ethernet.
<willmore>
GigE.
<willmore>
Nothing special that you probably don't already have lying around.
<ullbeking>
awesome, thx
<tuxd3v>
n x 5V/4A power supply for the MC1 computers
<tuxd3v>
20 watts power supply?
<tuxd3v>
20x4=80 watts
<tuxd3v>
crazzy
<ullbeking>
tuxd3v: i like your use cases for the opi plus one
<ullbeking>
cross compilation, testing bvinaries on arm64, etc
ldevulder__ has joined #linux-sunxi
<tuxd3v>
Opi one plus consumes around 5 watts.. a bit less at full throtle @1.8Ghz
<tuxd3v>
ullbeking, yeah its nice for those things, also if you want develop something on arm its good, and low power consumtion..
<tuxd3v>
consumtion -> consumption
<tuxd3v>
but there are not yet in mainline DVFS support, which is a shame in my opinion, thermal driver was just merged some time ago..
<willmore>
tuxd3v, 17W peak they spec.
<ullbeking>
tuxd3v: is the thermal driver for auto-throttling of the cpu when it gets hot?
ldevulder_ has quit [Ping timeout: 265 seconds]
<tuxd3v>
willmore, I hope you right, but even so its to high..
<tuxd3v>
:(
<tuxd3v>
rk3399 also consumes some..
<tuxd3v>
between 12w-16w, full throtle..
<tuxd3v>
everything max out
<tuxd3v>
but then you have the nanopi Fire3 octacore cortex a53 @1.6Ghz(overclocked), consuming 6.5Watts
<tuxd3v>
the performance in the big cores are not so big as in MC1, but the lower cores are very higher than in MC1
<tuxd3v>
6.5 watts
<tuxd3v>
but no mainline support
<tuxd3v>
:S
<tuxd3v>
ullbeking, it will serve for a lot of things
<tuxd3v>
when dvfs arrive,
<tuxd3v>
kernel 5.5 will be big, with crypto also included for h6
<willmore>
tuxd3v, they're A17's at 2GHz. That's a pretty old core running *hard*. These aren't like the new 12nm A73 cores where four of them run icey cold.
<tuxd3v>
gpu panfrost kernel driver and such :)
<willmore>
ullbeking, but that would be advocating for a different also non-Allwinner board. :)

<tuxd3v>
for the 3GB ram
<tuxd3v>
2GB
<tuxd3v>
and for the price
<tuxd3v>
yeah its nice, but consumes a lot of power
<tuxd3v>
I have a cluster of 4 nanopi fire3 all cortex a53, consuming around 25W
<tuxd3v>
32 cores
<ullbeking>
that sounds great!
<tuxd3v>
How is the Exynos support in the kernel?
<tuxd3v>
is it well supported?
<ullbeking>
one of these days, once i've learned sufficiently well about power electronics, i will use an ATX PSU with a breakout board to power all of my SBC's in a safe way
<tuxd3v>
ullbeking that seems a nice Idea..
<tuxd3v>
I tought of do some liquid cooling
<tuxd3v>
for my cluster
<tuxd3v>
I already have lots of components..
<tuxd3v>
but need the time to start it
<tuxd3v>
:D
<tuxd3v>
only one radiator and a fan on it
<tuxd3v>
but needs to develop more for that :(

victhor has quit [Ping timeout: 252 seconds]

tuxd3v, the exynos support for that chip is very good. The only think holding the vendor back to 4.14 is video codecs.
<willmore>
Which aren't really an issue for a headless box like this.:)
<willmore>
ullbeking, I like using modified ATX supplies. Older ones (very old like P4 era) work best as they had most of their power on the 5V rail instead of the 12V rail like modern supplies.
<willmore>
Optionally, get a standard 5V industrial supply for $20 somewhere and use it to feed the world.
<ullbeking>
willmore: i heard a while back that the old-style AT power supplies are actually preferable for this kinda thing than ATX PSU's, which are too clever
<willmore>
tuxd3v, I took the water cooling out of my PC when I last rebuilt. Used to have an i5-3570K @ 4.2GHz and now I have a Ryzen 7 3700X at 4.2GHz and it has twice the cores, four times the threads and cools fine on air.
<ullbeking>
also, by industrial 5V PSU, yeah i looked into this, and Meanwell have some really great PSU's
<willmore>
Yes, ullbeking that's true.
<willmore>
And they're pretty cheap (the industrial ones)
<willmore>
LED lighting brought the prices of 12V and 5V power supplies down a lot.
<willmore>
Meanwell is a very good brand. A bit pricey, but worth it for SBCs.
<ullbeking>
i might just get a meanwell psu and split the outputs to, say, 4 A per SBC
<willmore>
All though most non-Rpi SBCs are smart about 5V and regulate anything important and only pass on 5V to USB.
<ullbeking>
and RPi is not smart about this?
<willmore>
The nice thing about current is you don't have to split it, each board just uses what it needs.
<ullbeking>
right, but ideally you want to be able to supply for maximum draw simultaneous, right?
<willmore>
One of the Rpi did something stupid with the 5V input and assuming it wouldn't droop much and that causes tons of problems.
<willmore>
Yes, you want to support the maximum case, but you don't need to do anything with the wiring to 'split' the current. ;)
<willmore>
Boards just use what they need.
<willmore>
I don't mean to be insulting, I've just helped a lot of people with marginal understanding of electronics and want to make sure I'm being clear.
<willmore>
tuxd3v, what do the nanopi fire3 boards use for power input? Please don't let it be a micro-USB.

ullbeking: willmore: in our lab we have weird problems with ATX, we switched to dedicated 5V supply without any problem
<montjoie>
the only interest in ATX is the case were you need to supply both 5V and 12V boards
<montjoie>
but some boards (kvim2 for example) draw too much at startup and ATX dont like it
<buZz>
montjoie: not many ATX supplies like unbalanced loads on their rails
<buZz>
sometimes to get proper 12V , you also need to put a load on 5V
<buZz>
similar other way around
<montjoie>
buZz: furthermore, dedicated 5V supply are the same price (or lower) than ATX

yeah

I have used ATX PSU's for 5v and 3v3 at the same time, and it seemed to work ok but I didn't test very much because I get a bit nervous working with such a device until I understand the way the loads are supposed to be distributed, as per the 12v rail for example.
<KotCzarny>
load few amps on 5V line, then measure what's on 12V
<KotCzarny>
sometimes its funny
<ullbeking>
Is this all part of the ATX spec? Or just "undefined behavior"?
<KotCzarny>
undefined behavior or crappy psu designs
<KotCzarny>
but even better ones tend to suffer this effect
lurchi__ is now known as lurchi_
<montjoie>
if your goal is testing, you want predictable and reliable result, and I got too many problem with ATX
<KotCzarny>
even in meanwell dual voltage series in manual they state that both lines should be loaded
