Question about Rootfs generation.

[Slatepaws]

In reference to the Steam issue of the other discussion.

If i were to build my own root-fs, what would it entail. Specific amd64 tuning levels and cflags? What hardware should i set stuff like Mesa and x11 to target? Does the rootfs need the full kernel source?

Or is it just a simple chrootable crossdev install like say for gentoo?

It's mostly just a chrootable rootfs image with some minor modifications. For some of our images we build mesa with some minorly changed flags, like compiling with AVX2 enabled.

https://wiki.fex-emu.com/index.php/Development:Setting_up_RootFS Has some information

https://github.com/FEX-Emu/RootFS Or you can see what our generation scripts are doing directly.

Okay, so if i'm reading this right. Because the squashfs i get via the asahi overlay is really out of date. kernel 6.11 and similarly old versions of programs. All i have to do on my gentoo machines are either;

1. On the amd64, set up a new chroot intall, like i would newly installing gentoo. With the latest packages and transfer them over to the arm machine. Would be a pain to keep up to date though as i would have to transfer updated chroot's every once in a while.
2. On the arm machine, set up crossdev, do the same gentoo install as if on amd64 with multilib. and just use scripts to make it chrootable and then run-able for fex when needing to update.
