Wait these are mainframes so the bottom hypervisor is always from IBM and you run stuff in VMs, right? i have no clue | 18:18:10 |
 7c6f434c | The bright side is that there is something https://wiki.ubuntu.com/S390X | 18:18:28 |
| bl0v3 | its sorta what im trying to figure out | 18:18:28 |
| 7c6f434c | https://en.wikipedia.org/wiki/Linux_on_IBM_Z says that mainframes mean everything has to be somewhat virtualised | 18:18:51 |

The bright side is that there is something https://wiki.ubuntu.com/S390X gives me a 503 | 18:19:27 |
| 7c6f434c |
The boot loader for the s390x architecture is "zipl" (z initial program loader).
| 18:20:39 |
| bl0v3 | well i gotta go work on something else now but i can as it seems build a minimal system configuration already , though it would be useful to build some thing i can test in qemu before putting it on there | 18:20:55 |
| 7c6f434c | Loads for me but very slowly | 18:21:02 |
| 7c6f434c | * wiki page loads for me but very slowly | 18:21:10 |
| bl0v3 | https://www.ibm.com/docs/en/linux-on-systems?topic=u-boot-device | 18:22:48 |
| bl0v3 | actually this looks promising | 18:22:54 |
| bl0v3 | will look into this later | 18:22:58 |
| 7c6f434c | https://www.qemu.org/docs/master/system/s390x/bootdevices.html QEMU might support emulating the boot for the mainframes (but not most of the hardware) | 18:23:20 |

https://www.qemu.org/docs/master/system/s390x/bootdevices.html QEMU might support emulating the boot for the mainframes (but not most of the hardware) as i recall afaik that only runs via netboot, gotta check sorta busy rn | 18:24:02 |
| bl0v3 | will deffo continue this though | 18:24:11 |
| bl0v3 | just no time rn | 18:24:15 |
| bl0v3 | at least i now got nixpkgs.lib.nixosSystem {} to work so i have a toplevel system | 18:24:51 |
| bl0v3 | would essentially need to follow this spec and write a module to do it on each rebuild | 18:25:22 |
| bl0v3 | ive done that in the past for my custom kexec based bootloader but yeah no clue gotta look into this in a bit | 18:25:55 |
| bl0v3 | like from monday on i can work on this full time | 18:26:07 |
| bl0v3 | i need to check some libs though as i had to patch some packages as they woudln't cross compile properly i hope that won't blow up :) worst that hpapens is i try again | 18:27:21 |
