@matthewcroughan:defenestrate.itmatthewcroughan - nix.zoneI'm best at the boot flow itself, but not android software19:43:57
@cyclopentane:aidoskyneen.eupentane ⭔
In reply to @matthewcroughan:defenestrate.it
maybe you can teach me something
oh, contrary to what it might seem like, I have no idea about AOSP either
19:44:11
@cyclopentane:aidoskyneen.eupentane ⭔maybe we can dig up some good resources together ;)19:44:21
@matthewcroughan:defenestrate.itmatthewcroughan - nix.zonethe boot flow itself could be considered "android" though since ABL and all the stuff that gets you to executing a kernel is sadly android contaminated and controlled19:44:28
@cyclopentane:aidoskyneen.eupentane ⭔i mean, I don't really have any issues with that19:45:01
@cyclopentane:aidoskyneen.eupentane ⭔as long as the bootloader boots my kernels and initramfses, I'm happy19:45:22
@matthewcroughan:defenestrate.itmatthewcroughan - nix.zoneWell even the cool devices that are coming out now like Fairphone 5 and Shiftphone 8 are running a locked "secure boot on" ABL from the OEMs19:45:36
@matthewcroughan:defenestrate.itmatthewcroughan - nix.zonerather than just being normal devices that run an open bootloader, the OEMs fork edk2 and do annoying things 19:46:00
@matthewcroughan:defenestrate.itmatthewcroughan - nix.zonethen lock it, and they have bugs.. those bugs then are worked around later.. yada yada19:46:17
@matthewcroughan:defenestrate.itmatthewcroughan - nix.zoneThere is sorta fwupd support on the Shiftphone 8 which is interesting19:46:48
@matthewcroughan:defenestrate.itmatthewcroughan - nix.zoneI just worry that all the progress that gets made on these things gets dropped because it's effectively relying on 3 people to stay interested and hack on it 19:47:09
@cyclopentane:aidoskyneen.eupentane ⭔hmmmm19:47:16
@matthewcroughan:defenestrate.itmatthewcroughan - nix.zoneLike Caleb who is Linaro employed and whos attention could be diverted to something else at any moment19:47:37
@matthewcroughan:defenestrate.itmatthewcroughan - nix.zoneOr the two individuals working for Fairphone and Shift, who the same aplpies to19:47:51
@matthewcroughan:defenestrate.itmatthewcroughan - nix.zone* Or the two individuals working for Fairphone and Shift, who the same applies to19:47:54
@matthewcroughan:defenestrate.itmatthewcroughan - nix.zoneNot enough people who actually work on this stuff, and have access to NDA'd stuff and internal knowledge out there 19:48:09
@matthewcroughan:defenestrate.itmatthewcroughan - nix.zone* Not enough people who actually work on this stuff, and have access to NDA'd stuff and internal knowledge out there working on open source 19:48:13
@matthewcroughan:defenestrate.itmatthewcroughan - nix.zone* Like Casey who is Linaro employed and whos attention could be diverted to something else at any moment19:48:30
@matthewcroughan:defenestrate.itmatthewcroughan - nix.zoneI have an assortment of mobile devices running nixos anyway, maybe we can nerd out at nixcon :D19:49:44
@cyclopentane:aidoskyneen.eupentane ⭔nice, looking forward to it :D19:49:56
@cyclopentane:aidoskyneen.eupentane ⭔and lmk if you have any issues with my fork19:50:19
@cyclopentane:aidoskyneen.eupentane ⭔would love to see it tested on some more devices other than my FP4 before Atemu and I merge it one of these days19:50:44
@matthewcroughan:defenestrate.itmatthewcroughan - nix.zone Atemu: going to WHY? 19:51:39
@matthewcroughan:defenestrate.itmatthewcroughan - nix.zoneIs my understanding correct that you need to be running on x86 in order to build android?19:57:53
@matthewcroughan:defenestrate.itmatthewcroughan - nix.zoneAnd that native arm64 toolchains don't exist?19:58:00
@cyclopentane:aidoskyneen.eupentane ⭔Afaik yes19:58:07
@matthewcroughan:defenestrate.itmatthewcroughan - nix.zoneIt's so crazy that google depends on that lol19:58:17
@matthewcroughan:defenestrate.itmatthewcroughan - nix.zoneSuch cruft 19:58:23
@cyclopentane:aidoskyneen.eupentane ⭔have you ever tried to read git-repo source code? ,-,19:58:40
@cyclopentane:aidoskyneen.eupentane ⭔I have, and I ended up just testing the cases I was interested in instead of trying to understand it19:58:58
