 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 |

| Puna | just curious if you have any more insight into / ideas about that, was hoping to do installer tests for IEEE-1275 grub2 before committing to writing anything onto a real disk :) | 17:45:48 |

 lzcunt | Heyy, it looks like bash introduced a sanity check for strchrnul that fails when cross compiling (just like getenv) and bash tries to replace the implementation | 20:16:54 |
| lzcunt | but for static builds with mlibc it fails because mlibc doesn't have them as weak symbols (which is similar behaviour to BSDs) | 20:17:53 |
| lzcunt | someone working with cross compilation to BSDs should check if they're affected | 20:18:23 |
| lzcunt | if they're affected, bash_cv_func_strchrnul_works=yes when cross compiling to BSDs just like we currently do for getenv_works should be enough to fix it | 20:19:51 |
 Alyssa Ross | In reply to @sananatheskenana:matrix.org
someone working with cross compilation to BSDs should check if they're affected BSD cross works well enough that it should be quite easy to check yourself if you're interested (and want to also fix it for mlibc) | 20:22:44 |
| lzcunt | I have it fixed for mlibc locally | 20:23:01 |
| lzcunt | I'll check then I'll get them fixed in the same commit then? | 20:23:14 |
| lzcunt | Sorry for the slow progress on the mlibc PR btw, I was moving and I got into uni | 20:24:00 |
| lzcunt | Now I'm doing PRs in 0-credit classes | 20:24:21 |
| lzcunt | Checked, strchrnul appears to be a weak symbol on freebsd | 20:57:38 |
| lzcunt | And static bash cross compiles | 20:57:54 |

| Puna | booting fails, and display never gets any output, but baby steps 🙂 | 15:11:08 |
| Puna | fails in the emulation cus the installer's kernel can't find /dev/root, but it works on my hardware. maybe something works different on pseries machines there, hmm… | 22:20:45 |

 pandapip1 | Has there been any effort to port openwrt/pmos kernels & stuff for nixos | 03:12:12 |
