07:28 <thefloweringash> 4.20-rc2 with SUN8I_DE2_CCU gives me a working HDMI console!

09:55 <tilpner> thefloweringash - Which device is that?

10:03 <thefloweringash> Pine64(+) 2GB

10:04 <thefloweringash> PineA64*

12:54 <samueldr> thefloweringash: tilpner, same, but no Ethernet

12:54 <samueldr> (pine a64 lts)

13:01 <thefloweringash> is there any wisdom on the ethernet side? the upstreaming wiki says it was supported as of 4.15, but I always get `mdio_bus stmmac-0: MDIO device at address 1 is missing.` and `dwmac-sun8i 1c30000.ethernet eth0: stmmac_open: Cannot attach to PHY (error: -19)`

13:03 <samueldr> thefloweringash: not AFAICT

13:04 <samueldr> https://freenode.irclog.whitequark.org/linux-sunxi/2018-12-03

13:05 <samueldr> it's been asked twice on their IRC with the same issue, where the device is missing from the /sys/ tree

13:06 <thefloweringash> oh, I didn't realise there was a channel for that. I should join

13:07 <samueldr> though I feel reassured that on a non-lts the issue is similar, if not exactly the same

13:08 <samueldr> ethernet worked one time!

13:08 <samueldr> but silly me rebooted without dumping dmesg

13:08 <samueldr> to see if ethetnet would be working after a reboot

13:08 <thefloweringash> do you happen to know which module supports the wireless module they sell?

13:09 <samueldr> seems to be stmmac

13:09 <samueldr> tried embedding them in the kernel

13:09 <samueldr> with = y

13:09 <samueldr> with the AXP things

13:09 <samueldr> a peek at what I tried https://stuff.samueldr.com/screenshots/2018/12/20181203080944.png

13:16 <thefloweringash> for the wireless?

13:16 <samueldr> it was in the linked conversations, in the linked log

13:17 <samueldr> one thought that it was the AXP PMIC not being enabling correctly

13:17 <samueldr> and then I tried building MDIO think in the kernel, in case something was racing

13:39 <thefloweringash> Guess I'll leave that for another day

15:52 <samrose> do you know the proper long term place to add to this file when it's generated?

15:53 <samueldr> yes

19:48 <jabranham> Can anyone get mono to build on the Raspberry Pi 3 B+?

20:50 <samrose> samueldr: do you have any clues about how I might take a crack at having nixos load module vfe_v4l2 ?

20:51 <samrose> is it in /etc/modules-load.d/nixos.conf ?

20:52 <samrose> or maybe it is in firmware in modprobe.d/nixos.conf

20:59 <samrose> actually it seems that vfe_v4l2 us related to using a camera and all I am trying to do is get text console out on hdmi

21:07 <samueldr> oh

21:08 <samueldr> try 4.20-rc4, enabling SUN8I_DE2_CCU

21:08 <samueldr> I and thefloweringash had success on our devices with it

21:11 <samueldr> (though with failing ethernet)

21:15 <samrose> samueldr: thanks somehow I got ethernet working

21:16 <samrose> not yet on 4.20-rc4

21:16 <samrose> (but will try)

21:17 <samrose> samueldr: how did you enable SUN8I_DE2_CCU ?

21:17 <samueldr> through changing common-config.nix locally https://github.com/NixOS/nixpkgs/blob/master/pkgs/os-specific/linux/kernel/common-config.nix

21:19 <samrose> samueldr: so you set SUN8I_DE2_CCU = yes somewhere in there? under 'video'?

21:20 <samrose> or maybe 'media'?

21:20 <samueldr> it's not important where

21:21 <samueldr> well, for testing it isn't

21:21 <samrose> ah, ok

21:24 <samrose> samueldr: I guess this would otherwise go in an overlay, and would be = option yes intead of just = yes ?

21:24 <samueldr> not sure yet, it all depends on whether it's something that can be safely enabled for all aarch64 kernels or not

21:28 <samrose> ah just testing ok
