normally one might be inclined to increase the voltage to reduce charging current etc.
<Ke>
but not sure, what sort of tradeoffs there are, since that needs to be brought back to lower voltages to be actually used in most places
<Ke>
definitely the norm in the industry is that tens of watts are normally transferred with higher voltages

samueldr: do you have displayport working with your pinephone?
zupo has quit [Quit: My MacBook has gone to sleep. ZZZzzz…]
<sphalerite>
or rather: does anyone, and are there any tricks to it?
<sphalerite>
I've tried connecting mine to my USB-C monitor, and the USB works fine (mouse and keyboard which are attached to the monitor control the pinephone just fine), but I'm not getting any additional outputs in xrandr

I've not had it working under any distro yet, sphalerite
<Ke>
did you try reversing the connector orientation
<Ke>
for some pine devices it made a difference, can't remember, which ones
<craige[m]>
Excellent - that's sphalerite - I'll make sure to keep plugging away on the in future.
<craige[m]>
* Excellent - thanks sphalerite - I'll make sure to keep plugging away on the in future.

hm, but the power delivery from my monitor isn't working either, it doesn't charge while connected…
<sphalerite>
Will try reversing the connector
<sphalerite>
I can absolutely plug (no pun intended) the monitor that I have though, the Dell P2720DC, it works a charm with my laptop and it's great to have a dock-but-it's-inside-the-monitor-so-it-doesn't-take-up-any-desk-space
<sphalerite>
The U2721DE is also nice, it's similar but with a slimmer bezel and ethernet. I have that one at work.
<sphalerite>
Oh and displayport daisy-chaining so I can attach both of my external monitors with the one cable.
<samueldr>
also note that strictly "power delivery" chargers may or may not work
<samueldr>
I haven't been able to get any kind of answer about it
<samueldr>
and haven't tried back now that I have a device with actually working USB
<samueldr>
ah, this last page has more information about PD
<samueldr>
the ANX7688 has to be configured properly, for this the firmware has to be flashed, and a software component has to have the firmware be loaded into the ANX7688
<samueldr>
then it's able to do PD AFAIUI
<samueldr>
but PD will be limited to 3A 5V, which is fine

samueldr: wait, eDP or DP?
<samueldr>
well, Type-C alternate mode
<samueldr>
DP I guess
justanotheruser has quit [Ping timeout: 258 seconds]
<samueldr>
yeah, eDP is just another DP, so it was wrong, but I also see why I was thinking the alt mode was called eDP
<samueldr>
I guess we should always say "DisplayPort Alternate Mode on USB Type-C Connector"
<samueldr>
as per the standard name

i've finally gotten back around to installing on my two odroid hc1s. patagonicus any words of warning with current unstable?
justanotheruser has joined #nixos-aarch64
<samueldr>
edrex: arapov (not present on irc at the moment) seemed to imply the HC1 used the same U-Boot builds as the C4
<samueldr>
it uses a real ARM cpu instead of an emulated one
<samueldr>
which may or may not be problematic for some builds
<samueldr>
binfmt-misc also has the issue of having an ambiant impurity that it runs on a foreign architecture, and *could* run those foreign architecture binaries
<edrex>
oh, i thought the thing cole linked was for running on an amd64 host
<samueldr>
though not really an issue in the end
<samueldr>
nope, that VM runs on an aarch64 system :)
<patagonicus1>
For the linked issue reverting the linked commit worked for me. Unfortunately armv7 is usually so broken that I have to have two or three local changes on nixpkgs to make it build

[1/0/83 built, 32 copied (79.9 MiB)] building binutils-2.35.1 on ssh://pi@pi400 (round 1/2): checking whether build environment is sane... yes
<edrex>
It sounds like what is holding things back is lack of official arm7l build hosts to keep builds from drifting
<edrex>
but maybe there's too little interest because armv7 is less popular at least in devices with screens?
<edrex>
(new devices)
<samueldr>
mainly build infra issues
<samueldr>
most servers you can get can't do 32 bit arm
<samueldr>
and the one or two known hardware that can are extremely limited in numbers
<edrex>
oh, i was wondering about that. so the hetzer arm servers are a no go
<samueldr>
in addition to lacking the people-hours to actively work on slapping things into shape
<samueldr>
not sure
<samueldr>
depends on what they are
<samueldr>
didn't know hetzner had ARM servers
<edrex>
oh i think they EOL'd them awhile back..
<samueldr>
so yeah, many of the ARM server options are no-go for 32 bit arm

<clever>
from todays master
<clever>
samueldr: undoing the patch linked in the ticket does fix it (i believe), but that patch was to fix a ghc issue
<samueldr>
can we conditionally apply the patch on not armv7?
<samueldr>
sure, ghc won't build (maybe) on armv7l if that was the intent
<samueldr>
but if it unblocks most everything else it would be better
