 K900 | Mesa is already conditional on valgrind availability | 03:23:39 |
| K900 | If it's broken on whatever weird target you're into now, flag it as such | 03:23:51 |

If it's broken on whatever weird target you're into now, flag it as such Llvm musl is what they are doing rn iirc, not that weird. Tbh I'd enjoy a gnuless system. | 06:49:22 |
 Alyssa Ross | I would like us to actually fix the underlying problems... | 07:00:23 |
 matthewcroughan | What does postmarketOS do? | 12:19:11 |
| matthewcroughan | They have a fully working system with very impressive amounts of software running, and I doubt they are fixing these things upstream | 12:19:40 |
| matthewcroughan | Instead I think we need to do both fire patches off upstream and add conditionals whilst we wait for them to get merged | 12:20:09 |
| Alyssa Ross | so far the "fire patches off upstream" part seems lacking… | 12:20:27 |
| matthewcroughan | I believe postmarketOS just applies patches and leaves it at that | 12:20:31 |
| Alyssa Ross | why is postmarketOS the point of comparison here? | 12:20:42 |
| matthewcroughan | Actually pmos is just alpine. What foes alpine fo? | 12:20:52 |
| matthewcroughan | * | 12:21:03 |
| Alyssa Ross | alpine submits a lot of patches upstream | 12:21:13 |
| matthewcroughan | Why does their entire package set work on musl? | 12:21:12 |
| Alyssa Ross | because they test it with musl | 12:21:22 |
| matthewcroughan | * | 12:21:30 |
| Alyssa Ross | remember lots of the stuff you are trying to fix does work with musl, but not with musl+llvm | 12:21:38 |
| Alyssa Ross | which nobody has ever cared about until a month or two ago | 12:21:44 |
| Alyssa Ross | (in Nixpkgs) | 12:21:49 |
| Alyssa Ross | or it does work with musl, but doesn't work with cross compilation to musl, which again isn't something anybody has generally bothered to test | 12:22:19 |
| matthewcroughan | Okay but in this case, do you think they're shipping mesa with valgrind? | 12:22:36 |
| Alyssa Ross | easy to find out | 12:22:53 |
| matthewcroughan | Our mesa is super heavy | 12:23:05 |
| Alyssa Ross | but I suspect probably not because Alpine tries to be small | 12:23:07 |
| Alyssa Ross | and that means less optional dependencies enabled by default | 12:23:18 |
| matthewcroughan | Yes so I think there's a happy balance between conditionals and patches, and that not everything has to be an upstream patch | 12:23:47 |
| matthewcroughan | like in this case valgrind is pretty heavy and maybe not all platforms should include valgrind | 12:24:04 |
| Alyssa Ross | if there's a principled criteria for that, sure | 12:24:18 |
| Alyssa Ross | but there's no fundamental reason we should include valgrind for GCC builds and not LLVM ones | 12:24:44 |
| matthewcroughan | Sure, my discovery has highlighted two things:
- An issue with valgrind that needs to be fixed upstream
- Maybe valgrind is really heavy and we don't need it in mesa for all platforms
