sadoon[m] | @lkcl re: circular dependancies, we don't have to worry about those | 16:40 |
sadoon[m] | We can use the ppc64le packages which have VSX et al enabled to build ones without them enabled | 16:41 |
sadoon[m] | So, we can rebuild them on a per package basis, order does not matter | 16:42 |
sadoon[m] | It's technically not cross compilation | 16:42 |

sadoon[m] | I just need to make a list of packages installed in a debootstrap and rebuild those one by one, and then perhaps once again just to be safe | 16:42 |
sadoon[m] | It's similar to using sid to build debian 13 for example, you just build the stuff you need | 16:43 |
sadoon[m] | "-O2 -pipe -mcpu=power9 -mno-altivec -mno-vsx -mno-crypto -mno-htm -mlong-double-64" is literally all we need :D | 16:44 |
sadoon[m] | While the debian packages are building I need to look into a way to force qemu to not use these ISA extensions | 16:45 |
sadoon[m] | If you think that's necessary, or we can move it to another budget | 16:45 |
sadoon[m] | Because there's no ISA 3.0 compliant chip that I know of that doesn't have these features | 16:46 |
sadoon[m] | Although if I find a kernel command line option that disables those that'll do | 16:47 |
sadoon[m] | Doing the 2nd rebuild for gentoo, then I'll do the rebuild of debian while testing if I can disable VSX and co one way or another | 16:47 |

programmerjake | x86 gets 32 gprs and 3-arg integer ops?! about time... https://www.intel.com/content/www/us/en/developer/articles/technical/advanced-performance-extensions-apx.html | 21:49 |
programmerjake | they also have conditional load/stores | 21:53 |
