 @lotte:chir.rs | I looked at the device tree for my device and it seems very different, referring to drivers that do not exist upstream | 15:26:47 |
 K900 | There's a PR that allows quickly building out of tree DTS but it's bad and the person that wrote it ignores feedback | 15:26:50 |
| K900 | But you could pick it up | 15:26:50 |
| @lotte:chir.rs | Like at a minimum all of the display stuff wouldn't work | 15:27:19 |
| K900 | Well you'd have to port that if there's no mainline compatible tree yesn | 15:27:51 |
| K900 | * | 15:27:55 |
| @lotte:chir.rs | yeah i guess i have to reverse-engineer the firmware because at least on the sony device that i do not have and is supported upstream it just uses the framebuffer at a fixed address | 15:29:02 |
| @lotte:chir.rs | tbh i could try to run the sony dts but that supposedly doesn’t work | 15:29:15 |
| K900 | I'm guessing it's just using whatever dumb framebuffer set up by the earlier boot stages then | 15:31:32 |
| K900 | And not doing GPU stuff correctly | 15:31:38 |
| K900 | Which will also make the experience of actually using the thing significantly worse | 15:31:50 |
| @lotte:chir.rs | ah | 15:32:20 |
| @lotte:chir.rs | so the downstream kernel might be better? | 15:32:28 |
| @lotte:chir.rs | it’s not yet EOL :D barely | 15:34:13 |
| K900 | Better in some ways, likely significantly worse in others | 15:34:15 |
| @lotte:chir.rs | 5.4 lts | 15:34:16 |
| @lotte:chir.rs | yeah i tried running it on my older phone but there the kernel is so old most of the software doesn’t even run on it | 15:38:29 |
| @lotte:chir.rs | ah yeah display is specifically marked as borken eyah | 15:46:23 |

 Puna | r-burns: hi! i'm currently checking if i can get nixosTests running on my POWER machine. i see that you added the qemu entries for these back in https://github.com/NixOS/nixpkgs/pull/115175 , and you mentioned there that there'd be more changes down the line. did this change work for you, and did those other changes ever materialise into PRs? | 17:35:55 |
| Puna | as-is, qemu seems unable to launch a regular kernel with the powernv platform selected. i only managed to get something resembling a booting system out of that platform by passing petitboot files into -kernel and -initrd. since we also use those options to start VMs for tests though, that doesn't really work… | 17:38:33 |
| Puna | the pseries platform can definitely use -kernel and -initrd to boot a system, but on a big-endian POWER system any kernel I try just runs into invalid memory access almost immediately. so that also doesn't really work, at least not for natively running the tests | 17:40:06 |
