 ius | I looked at it before, but concluded it doesn't fit the use case - although they pull in qemu's tcg the SoC itself seems implemented in C#. Guess it'll take slow to a whole new level. | 08:05:28 |
| ius | Qemu system emulation of one of the virt RISCV targets will be (a lot?) faster. It's a neat project if you have on board peripherals you'd like to emulate (or co-simulate?), though | 08:06:31 |
 Jamie | oh I have a Freedom Unleashed sitting unused i’d be happy to contribute to a build farm if it’d be helpful | 09:47:44 |
| Jamie | or uh | 09:48:03 |
| Jamie | HiFive Unleashed that is | 09:48:13 |
| Jamie | wait no sorry its an Unmatched | 09:56:59 |
| ius | Zhaofeng Li: FYI, I was sponsored a board as well, and it just turned up on my doorstep out of the blue | 12:46:15 |
| ius | Bonus rant: had to scramble for cash, because apparently UPS over here only accepts cash payments in exact change - it's 2022 after all | 12:55:45 |
 7c6f434c | This is their attempt to only accept card payments without saying they only accept card payments? | 12:58:45 |
| ius | No, they don't take cards at all. | 13:01:20 |
| 7c6f434c | Do they try to get written checks?? Or do they simply hate the world and want the world to feel it? | 13:02:56 |
| ius | The proof of payment I got sports 2 checkboxes: 'check' or 'cash'.
National banks haven't issued any checks since 2002. The only reason it's on there because someone probably translated a US form/procedure. | 13:12:57 |

 Zhaofeng Li | Nice! My sdimage built overnight, but I haven't had a chance to test it yet | 18:45:18 |
| Zhaofeng Li | Also roughly what I got to:

| Zhaofeng Li | The Fedora image boots using UEFI, and the factory U-Boot isn't set up to boot with extlinux.conf with various environment variables like kernel_addr_r are missing. After setting the environments manually I could start the kernel, but we should use UEFI as well. | 19:27:39 |
| ius | I cheated, it's a cross compiled kernel only (because I still have to build it natively). | 19:27:40 |
| ius | Yeah, I have been experimenting with UEFI and was thinking the same thing. | 19:28:05 |
| Zhaofeng Li | * The Fedora image boots using UEFI, and the factory U-Boot isn't set up to boot with extlinux.conf with various environment variables like kernel_addr_r missing. After setting the environments manually I could start the kernel, but we should use UEFI as well. | 19:28:07 |

| ius | The sdImage derivation needs some work though, think it would be nice if it could generate an ESP + systemd-boot | 19:29:15 |
| Zhaofeng Li | Yeah, that would be the annoying part. The sd-image generator is very inflexible. | 19:30:23 |
| ius | I have some half-finished derivation to declaratively specify a partition table for sdImage, but hadn't gotten around to finishing it. | 19:32:59 |
| Zhaofeng Li | For this, we should be collaborating with @samueldr because that's what he's doing in tow-boot. | 19:35:00 |
| Zhaofeng Li | I'm not sure whether he intends to upstream any of that into nixpkgs, though. | 19:35:24 |
| ius | Right, was not aware | 19:41:20 |
| Zhaofeng Li | Ok, gonna continue tonight | 19:48:40 |
| ius | So for some reason my standalone cross compiled kernel starts, but the one I yanked out of a sdImage build does not. Same tree, so it must be the config? | 19:56:35 |
| Zhaofeng Li | Might be, how are you generating the initrd in the standalone case? | 22:34:05 |
| Zhaofeng Li | I pushed my expression here: https://github.com/zhaofengli/nixos-riscv64/blob/master/pkgs/linux-visionfive/default.nix | 22:36:37 |
