01:11 <red[evilred]> sphalerite (IRC): also - have to find out if NixOS on this thing needs SD / SATA / M2 / eMMC to run

01:49 <red[evilred]> oh wow - that RAM is spendy

01:57 <red[evilred]> sphalerite (IRC): how much RAM you thinking of putting in it?

02:22 <pbb> colemickens, samueldr: you talked about an issue with booting mainline kernel using u-boot on a raspberry pi a few weeks ago. something with "RD image overlaps OS image". did you find a solution to that?

02:26 <pbb> using sd-image-aarch64.nix as basis works with lts kernel but not with latest kernel

02:29 <samueldr> uh, I don't think I personally experienced it, I must have been only tangentially involved in the discussions

02:29 <samueldr> in the u-boot env there are vars that can be tweaked

02:30 <samueldr> those are seeded by platform-specific defaults IIRC

02:30 <samueldr> `and IIRC those vars include "addr" as part of their names

02:31 <pbb> is this in the generic-extlinux-compatible module or in the u-boot defconfig file or where?

02:31 <samueldr> the env I assumed you'd checked using the u-boot command-line on the device

02:32 <samueldr> otherwise it may be part of the defconfig for some platforms

02:32 <samueldr> IIRC it isn't for some other

02:32 <samueldr> (the command to check the env on-device is "env")

02:32 <pbb> okay. different question: is it possible to boot a mainline kernel using the raspberry pi bootloader?

02:33 <samueldr> AFAIK yes

02:34 <pbb> Thanks. I have no idea what exactly I could try with the u-boot env addr stuff. So I'll try the rpi bootloader first.

04:23 jb55 has joined #nixos-aarch64

04:23 <samueldr> in u-boot, for the raspberry pi it seems to be defined by include/configs/rpi.h

04:24 <samueldr> (for the defaults)

04:24 <samueldr> ramdisk_addr_r=0x02700000

04:26 <samueldr> though I'm less confident in what I'm saying now

08:59 <sphalerite> power supply is included in the case

09:01 <sphalerite> oooh I have my shipping notification too!!

09:01 <sphalerite> oh wow it's supposed to arrive on the 4th

09:01 <sphalerite> I… probably won't be there to accept it :|

11:26 <pbb> now next question: anyone had u-boot running on the rpi4?

11:29 <pbb> bootcode.bin is the same on all raspberry pis, right?

11:45 <pbb> I found https://github.com/NixOS/nixpkgs/pull/97883, now testing

13:54 <manveru[m]> i'm looking for some advice to start hacking on my remarkable 2 tablet :)

13:54 <sphalerite> siraben's been doing lots of remarkable stuff, though with the 1 I think

13:55 <siraben> yeah

13:55 <manveru[m]> so far i got a simple flake that does cross-compilation and installs some small utils and japanese fonts

13:55 <siraben> one of the few NixOS users in the rM hacking community :)

13:55 <siraben> manveru: nice! is it public?

13:56 <manveru[m]> not yet...

13:56 <siraben> also see https://github.com/siraben/nix-remarkable and https://github.com/Eeems/oxide

13:56 <siraben> oxide has a nix expression as well, not a flake yet though

13:56 <manveru[m]> it's pretty small, one sec

13:56 <siraben> here's how it's built https://github.com/Eeems/oxide/blob/master/oxide.nix

13:56 <siraben> turns out you can use rM's official toolchain just fine in Nix, who knew? heh

13:57 <manveru[m]> https://gist.github.com/manveru/1baa9db251f0a269512970495bc332a1

13:58 <manveru[m]> i've been thinking of how to best manage my own systemd services and installing stuff like a launcher using it

13:58 <manveru[m]> will take a look at oxide

13:58 <siraben> manveru: oh cool, how would I run this flake on the tablet?

13:59 <manveru[m]> i mostly did `nix build .#profile && NIX_SSHOPTS="source ~/.profile;" nix-copy-closure --to remarkable.fritz.box ./result`

13:59 <manveru[m]> and on the remarkable then `nix profile install <that-result-path>`

13:59 <siraben> ah, you're using nix 2.4 on the tablet?

14:00 <manveru[m]> yeah

14:00 <siraben> yeah the NIX_SSHOPTS is annoying but that's because the tablet uses dropbear

14:00 <siraben> instead of openssh

14:00 <manveru[m]> yup

14:00 <manveru[m]> i still can't get it to work with my ssh keys :(

14:00 <siraben> how did you install it on the tablet? I just cross-compiled it today

14:00 <manveru[m]> probably doesn't like ed25519

14:01 <manveru[m]> i used the prebuilt nix for some raspberry i think

14:01 <manveru[m]> then cross-compiled nixUnstable and copied it over this way as well

14:02 <manveru[m]> thus replacing the precompiled one

14:02 <manveru[m]> nothing streamlined really ^^;

14:04 <siraben> yeah

14:04 <siraben> I had no idea nix profile was a thing, I haven't really looked at the newer subcommands stuff

14:05 tilpner has quit [Remote host closed the connection]

14:05 <manveru[m]> it's a really nice replacement for `nix-env` :)

14:09 <manveru[m]> the vnc stuff looks interesting... you could use this as a second monitor?

22:33 <s1ng0c> @samueldr I tried to build example/demo for pinephone but seem build broken due to mobile-nixos/modules/cross-workarounds.nix, could you check

22:35 <samueldr> it's broken *because* of it, but it's not expected to build with cross-compilation because of upstream Nixpkgs

22:35 <s1ng0c> security.polkit.enable and services.udisks2.enable are conclicted with X11 selections

22:35 <samueldr> s1ng0c: assuming you're not building natively on aarch64

22:35 <s1ng0c> no, I have x86_64

22:35 <s1ng0c> cross compiling

22:36 <samueldr> the demo image won't cross-compile, known issue, it's bringing in a *boat load* of stuff that has multiple distinct issues with cross

22:37 <s1ng0c> I tried to add Wayland + Weston to local.nix, it was also not worked :(

22:37 <samueldr> for the time being you can assemble an image by `dd`ing the prebuilt rootfs from an Hydra build on top of the partition from a normal build

22:37 <samueldr> https://hydra.nixos.org/job/mobile-nixos/unstable/examples-demo.aarch64-linux.rootfs

22:37 <s1ng0c> ok

22:37 <samueldr> you will want to expand the partition first using any partitioning tool

22:38 <samueldr> otherwise it won't fit :)

22:38 <s1ng0c> yah
