Cover letter [Buildroot] [PATCH 0/2] add support for xtensa back to buildroot
Hello Chris,
Quoted 13 lines · Chris Zankel
I understand your concern, and I guess it won't help that I had patches to clean up Buildroot for Xtensa laying around for over a year :-[ So, my promise would be to actually submit patches when I have them.
Part of the problem was that it wasn't just Buildroot, but other parts (uClibc, kernel, etc.) were also missing or having outdated changes, so it would have required to push a lot of patches. I have been working to get those patches in the corresponding trees first, and Buildroot actually now builds and runs out of the box on Xtensa with just those two patches and a generic patch for uClibc-snapshot. So, maintainability and detecting breakage will be much easier, and I intend to verify it on a more regular basis.

I'll send an updated version of the two patches where Crosstool-NG is disabled for Xtensa.
Excellent, sounds good.
I've also seen that Qemu has an Xtensa support. It would be nice if you could create a qemu_xtensa_<somemachine>_defconfig with the necessary kernel configuration and al (see other qemu_<foo>_defconfig that we have in configs/) so that other people could build a Xtensa userspace and run it inside qemu. At the moment, the qemu-system-xtensa supports the following machines:
$ qemu-system-xtensa -M ? Supported machines are: none empty machine lx60 lx60 EVB (dc232b) lx200 lx200 EVB (dc232b) sim sim machine (dc232b) (default)
Thanks!
Thomas
