[PATCH] qemu: add ppc64le support to COMPATIBLE_HOST

[PATCH] qemu: add ppc64le support to COMPATIBLE_HOST

[Andrew Geissler]

The move to qemu 11 and the enforcement of 64 bit machines broke ppc64le
machines. Add ppc64le wherever there is a ppc64 machine.

Re: [OE-core] [PATCH] qemu: add ppc64le support to COMPATIBLE_HOST

Hi Andrew, Mingli,

Interestingly this patch from Andrew conflicts with a patch from Mingli Yu which changes ppc64 to powerpc64[1].

Without triple-checking I’m more liable to believe your patch as I expect that you’re actually running PPC64LE servers (and also touches more places where COMPATIBLE_HOST is set), but I’m also wondering what Mingli’s patch is doing because it must have been sent for a reason.

Can you both compare each-others patches so we can understand what happened?

Cheers,
Ross

Yep I tested my patch on our POWER9 ppc64le based machine and verified it allowed me to build the latest OpenBMC distro. I submitted this patch because our CI process that utilizes a ppc64le stopped working when we picked up the latest oe-core in OpenBMC.

I poked around a bit and when I look at a POWER server that not running in little endian mode, I don't actually see ppc64 or powerpc64 from Mingli patch. As far as I can tell it's just powerpc (uname -p). So I don't have a lot vested in the non-ppc64le portion. If Mingli can confirm it tested fine for their config then I'm good if we just merge both patches, otherwise please merge mine at least :)
