 Anderson Torres | * If the POSIX API can be used, maybe the BeOS API will not be a huge problem... | 12:27:01 |
 alyaeanyx | How do you get the avr-gcc cross-compiling chain for AVR microcontrollers in Nixpkgs? I've tried crossSystem = { config = "avr-unknown-unknown"; }; and some variations of that | 23:32:38 |

I want those more riscv cores How come? | 21:04:43 |
| matthewcroughan - nix.how | Can you do something meaningful with an increased core count? | 21:04:58 |
| matthewcroughan - nix.how | Let's say I have a really powerful x86 processor, that has 4 cores 8 threads. Can I be more effective by making a risv64 QEMU VM with more than 4 cores? | 21:05:34 |
| matthewcroughan - nix.how | Can I lie and get more performance out of the VM, and make more use of the host processor? | 21:05:45 |
 Zhaofeng Li | You don't, it's mostly for when you have a 5950X with 32 threads for example | 22:07:25 |

You don't, it's mostly for when you have a 5950X with 32 threads for example I do actually have that :D | 17:37:07 |
| matthewcroughan - nix.how | but would I not get more performance out of the vm if I lied and said I had 64 threads? | 17:37:48 |
| matthewcroughan - nix.how | or is qemu smart enough to completely saturate each thread? | 17:38:10 |
| matthewcroughan - nix.how | I'm basically asking if it works like this https://nixos.org/manual/nix/stable/advanced-topics/cores-vs-jobs.html where there is a tradeoff. I don't expect it to, but it's worth asking. | 17:39:11 |

 ius | Zhaofeng Li: Thanks for mentioning me on that VisionFive kernel PR. Been a bit busy lately, but otherwise I would've missed it. Kicked off a fresh qemu-user build as well to see where things stand. | 20:13:09 |

 samueldr | Zhaofeng Li: looks like someone started working on some level of support for the VisifonFive in Tow-Boot, if it matters for you
| 16:43:34 |
| samueldr | (haven't really looked into it yet) | 16:44:09 |

| Zhaofeng Li | Oh nice, I haven't had much time to look into RISC-V stuff lately so this is very welcome. | 21:23:21 |
| Zhaofeng Li | This person is also trying to upstream my sd-image stuff in https://github.com/NixOS/nixpkgs/pull/168826 with the partition hack | 21:24:43 |
| 22 Apr 2022 |
| samueldr | just saw the ping | 01:25:47 |
| samueldr | I don't have the equipment, but can obviously answer the general integration question, as long as you (and Madouura) can find the facts as needed :) | 01:26:26 |
