 Stas | i always assumed that the userspace qemu is the more elegant one | 10:28:23 |
 Alyssa Ross | very much not the case | 10:28:51 |
| Alyssa Ross | it has to implement the whole Linux API, so you'll frequently run into stuff that isn't implemented or doesn't work right | 10:29:11 |
| Alyssa Ross | massively bigger surface than emulating hardware | 10:29:19 |
| Stas | true that :( When it runs well, it is like it is not there though | 10:29:38 |
| Stas | I use it to compile all my arm64 builds, not cross compile | 10:29:54 |
| Stas | works perfectly, albeit slower | 10:29:59 |
| Stas | * works perfectly, albeit slower than native of course | 10:30:05 |
| Alyssa Ross | a VM set up as a remote builder is also like it's not there, if you're doing Nix builds, and much more reliable | 10:30:30 |
| Stas | I am considering it, as I want the original 32bit arm too. Hetzner's Neoverse cores do not support the old isa though :( | 10:31:29 |
 Lotte (it/its)/Cinny (she/her) θΔ& | i wonder if such a vm would alleviate the cpu cache thrashing that i have noticed with qemu-user because you can effectively limit and/or isolate the emulation to specific cpu cores | 10:36:46 |

| Lotte (it/its)/Cinny (she/her) θΔ& | (i presume that is what it is, when running large gcc compile tasks in qemu-riscv it would make video games stutter) | 10:37:32 |
