 colemickens | I think I'll just use an existing microsd card and save this for when I have some ephemeral OS booted to peek at... | 02:01:50 |
 Zhaofeng Li | Heh, nice repackaging | 02:07:01 |
| colemickens | huh, maybe it was intentional and they pre-loaded an image and I missed the memo. | 02:18:06 |
| colemickens | do I need to run that to get an updated u-boot first? so far it's not showing much signs of doing anything | 02:23:52 |
| Zhaofeng Li | No, you should be able to see HDMI output from the NixOS image in a minute or so. Do you have a USB to serial adapter? | 02:25:29 |
| colemickens | yeah, I'm headed for that in a minute. Does it boot without the fan attached? | 02:28:27 |
| Zhaofeng Li | It does, and I don't have a suitable fan either | 02:29:22 |
| colemickens | welp, about to grab it but the microsd they sent has stuff on it and it doesn't seem to boot either | 02:46:50 |
| Zhaofeng Li | What do you see on the serial line? | 02:47:42 |
| colemickens | evidence that its working :P | 02:59:52 |
| colemickens | I think that it just completely fails to output to this particular monitor, but I can see nixos stage2 going. Excellent! | 03:00:14 |
| Zhaofeng Li | Maybe it's related to the DRM oops. You can try changing the kernel config to make it built in | 03:02:15 |
| Zhaofeng Li | Sadly I won't have much time to take a look myself until next week 🙁 | 03:02:26 |
| colemickens | oh, I don't even think I'm going to use the hdmi much for now unless another project makes a lot of serious progress :) | 03:02:56 |
| colemickens | this is really awesome, between your repo and having this up with serial access, I'm already rolling. thank you! | 03:03:14 |
| colemickens | how's the riscv64 qemu perf on x86_64-linux? I'm trying to figure out if I should be building on device or if I'm better off just paying a few bucks to boot a Threadripper and let it go once a week. | 03:45:26 |
| Zhaofeng Li | On my 3900X, qemu-system was roughly on par with my HiFive Unmatched in the single-core 7z b benchmark. qemu-user binfmt was considerably faster, but some packages don't build. | 03:55:03 |
| colemickens | it's easy to workaround but the visionfive nixos module isn't part of the flake outputs | 04:09:45 |
| colemickens | also curious if theres a wider riscv64 matrix room | 04:14:45 |
 Jamie | wider riscv64 is called riscv128 | 05:52:34 |
| Jamie | :3 | 05:52:35 |

so, my visionfive board arrived, and I figured I'd use the microsd they sent and then I start to open and notice this: https://photos.app.goo.gl/5TnSws4szCYktRm99 Surgically provisioned fedora RISC-V image.. | 09:01:14 |

| colemickens | Any idea if uboot riscv cross-compiles? I'm close to something neat, if so. | 23:57:20 |
| colemickens | I'll play with the nixpkgs branch after a bit, gotta do a call | 23:57:29 |

| colemickens | hm, I'm trying to boot qemu with an opensbi build with the kernel as a FW_PAYLOAD and then directly loading kernel but it's not going super well so far -_- | 01:45:00 |
