 Puna | the alternative is to figure out & fix all of the endianness issues in glslang, spirv-tools, and spirv-llvm-translator, and then check if mesa's mesa_clc tool still has any parsing issues. which sadly takes alot more spoons than i can allocate to this rn | 14:18:25 |
| Puna | i'll see if i can get https://github.com/NixOS/nixpkgs/pull/480841 ready this week - that'll at least further document in one of these packages that parsing on non-LE is just messed up | 14:22:02 |
 K900 | I mean that's not my concern really | 14:33:46 |
| K900 | I just really don't like the nixpkgs side implementation | 14:33:51 |
| K900 | At least I think we should flag every package that's known broken on BE as such | 14:34:08 |
| K900 | And then maybe hoist the conditionals somehow | 14:34:18 |
| K900 | Which sucks | 14:34:21 |
| Puna | can mark those packages as broken, but i think we had smth (at the very least a preference maybe?) against making features of thing depend on whether other things are marked broken, cus it'd randomly flip stuff on n off? so the condition in mesa would still p much be platformOpenCLWorks = stdenv.buildPlatform.isLittleEndian or smth like that | 14:43:02 |

 Stas | the G5 was compiling all through the night. Managed to bootstrap gcc, and is now on python | 09:19:31 |
| Stas | I need to put a power meter on it, to see how much power it guzzles. Exhaust is not as hot as I expected, though | 14:17:15 |
 Artemis Tosini (NixOS) | I suppose that's what happens on old machines, a full FreeBSD bootstrap to stdenv takes only a few hours on my VM | 14:24:07 |
| Puna | dunno how accurate this is, but apparently the windfarm module exposes current & voltage data of the cpus

Your PowerMac G5's CPUs are currently drawing: 226.088W
Calculated using the following equation: ((5.358 + 4.663) * 12) + (45.532 * 1.247) + (39.184 * 1.252)

| Puna | which checks out compared to this blob post where someone put an external watt-meter on their g5

| Puna | available things in there depend on the machine model i think… i don't have cpu-power-* on my end, maybe that has smth useful? | 15:47:25 |
| Puna | * available things in there depend on the machine model i think, there's abunch of different windfarm submodules for handling the differences there… i don't have cpu-power-* on my end, maybe that has smth useful? | 15:48:44 |
| Stas | I will investigate it for sure. | 15:52:39 |
