Solved FreeBSD 13 Images on MIPS

[fel1x]

I want to try FreeBSD on mips on QEMU. According to FreeBSD architecture tier, mips32 and mips64 are tier 2, but I cannot find them here. Should I manually build FreeBSD like this? Or is there FreeBSD for MIPS image somewhere?

Thank you!

dd_ff_bb In wiki It says it does not provide release image, but it seems that they do not provide snapshots. And can I ask why there is no mips release image?

Tier 2 platforms are functional, but less mature FreeBSD platforms. They are not supported by the security officer, release engineering, and port management teams.

Do you know why a release image was never created for MIPS?

Sorry, I did not realise I asked basically the same question. Still many Tier 2 architectures do have release images, so I wonder if there is a particular reason for it.

Thank you!

Did it work for you? I try the same approach but its failing me.

I tried it and it doesn't work, it fails to spawn init. I did debug it around a bit, I noticed that failure occurs in do_execve(). The address it tries to copy into, 0x7FFFF000 is not mapped. I have no idea why, kernel-userspace split is on the boundary of 0x80000000. Maybe a guard page ? But I'd expect vm to be able to work with that.

Anyway when you try to build anything for mips you get this message:

which gives you a clue about the future.
