 Alyssa Ross | Not sure if this will interest anybody but me, but I figured out why pkgsStatic Rust builds don't work on riscv64 :) https://github.com/NixOS/nixpkgs/pull/406797 | 17:10:47 |

| Alyssa Ross | Is the VisionFive2 the RISC-V computer to get, or is there anything out there with more RAM? | 08:23:10 |

Is the VisionFive2 the RISC-V computer to get, or is there anything out there with more RAM? there's the milk-v pioneer, but it's pricey. alternatively, EIC7700X boards (milk-v megrez, pine64 starpro64) go up to 32G but they are all out of stock | 08:35:56 |
 Steven Keuchel | The p550 cores (e.g. EIC7700X) are currently the fastest commercially available ones. | 08:41:07 |
| Steven Keuchel | Much better experience than the VF2. | 08:41:23 |
| fgaz | and apparently spacemit m1 based stuff also goes up to 16G but it isn't faster than vf2 despite the higher core count | 08:41:45 |
| Steven Keuchel | Pioneer has more cores, but the cores themselves are slower. | 08:41:47 |
| Alyssa Ross | Pioneer seems unavailable anyway | 08:48:23 |

| Steven Keuchel | No mainline support yet. Vendor kernel needs some custom CONFIG values to compile on Nixos. | 08:57:23 |
| Alyssa Ross | yikes | 08:57:39 |
| Steven Keuchel | At least the vendor uboot has distro boot enabled by default. | 08:57:57 |
| Alyssa Ross | maybe visionfive is the way to go then | 08:58:04 |
| Steven Keuchel | Depends on what you want to do. | 08:59:02 |
| Alyssa Ross | mostly I want to test generic OS images I'm building, so only systems with good mainline support are really interesting | 09:00:33 |
| fgaz | then vf2 is 100% the way to go at the moment | 09:01:42 |
| Steven Keuchel | And you build those through cross compilation or do you want to build them on the device? | 09:02:25 |
| Alyssa Ross | Native | 09:03:01 |
| fgaz | * then vf2 is 100% the way to go at the moment ah right native compilation | 09:04:13 |
| Alyssa Ross | (I know it will be very slow, that's fine) | 09:05:06 |
| fgaz | the "low" amount of RAM is also a problem for some packages, but a bit of swap is enough to compensate in my experience | 09:07:51 |
| fgaz | unless you want to build a browser | 09:07:54 |
| Alyssa Ross | I would ideally like Firefox but I can live without it | 09:08:38 |
| Alyssa Ross | Apart from that I don't think there's anything particularly big | 09:08:52 |
| Steven Keuchel | if mainline is a requirement then the vf2 is probably still the best option | 09:09:14 |
| Alyssa Ross | It also seems by far the easiest to obtain | 09:09:31 |
| Steven Keuchel | have not followed what happened in mainline in the last two months | 09:09:39 |
| Alyssa Ross | Looks like still no HDMI, but if I have to apply a few patches in the interim that are on their way upstream that's fine | 09:10:09 |
| Steven Keuchel | I used to compile firefox natively before. But now webkit is quite broken on risc-v which is a dep. I think build time only. | 09:10:54 |
