 Lotte (it/its)/Cinny (she/her) θΔ& | do apple silicon chips even support big endian mode? | 06:28:25 |
 K900 | You don't write "the IR is host endian" into your spec if you have EVER used a BE system | 06:28:45 |
 Puna | we build all drivers on all platforms | 06:29:03 |
| K900 | And more specifically Asahi we build on all platforms because it also outputs the standalone shader compiler for the build platform | 06:29:39 |
| Puna | # We enable as many drivers as possible here, to build cross tools
# and support emulation use cases (emulated x86_64 on aarch64, etc)
| 06:29:41 |
| K900 | Which we need to use for cross | 06:29:43 |
| Lotte (it/its)/Cinny (she/her) θΔ& | ah | 06:29:57 |
| Puna | i doubt anyone's doing asahi dev on 20yo PowerMacs, but y'know | 06:30:52 |
| Lotte (it/its)/Cinny (she/her) θΔ& | probably because the predominant architectures over the past two decades or so have just been little endian
but also like it costs very little to go “the ir is little endian”, loading/storing little endian data is cheap on ppc
| 06:31:49 |
| Lotte (it/its)/Cinny (she/her) θΔ& | although more likely than not they want to cut corners in the serializer/deserializer | 06:32:40 |
| Puna | cba to work that out rn, patched -Werror=format -Wformat-security out of the meson.build.
builds cross ig. | 07:09:53 |

| Stas | Hello! Joining here for my Mac G5 nixos efforts :) | 12:08:14 |
| Puna | i prefer thinking of it as a general ppc64 effort that just so happens to be done on G5 machines :) | 16:41:50 |
| Puna | more affordable & easier to come by than RS/6000 or pSeries machines | 16:43:46 |
| Stas | I am waiting for POWER8 gear to be discontinued at work to get my hands on them | 17:05:51 |
| Stas | Even helping with migration efforts ;) | 17:06:15 |
| Puna | ooh that'd be nice. do you happen to know what boot mechanism they use? i assume its nothing like the G5 or its POWER-based contemporaries (CHRP). what was it... OPAL & skiroot/skiboot? | 17:24:18 |

| Stas | They boot up very much like rs/6000 ipl | 18:27:36 |
| Stas | In my case they go to PowerVM hypervisor, but you can run AIX or any other OS | 18:28:19 |
