Hi ktr/lkp,
Can you explain why the (previously) attached .config file says:
CONFIG_32BIT=y
but in the email text above, it says:
config: powerpc64-randconfig-r001-20211012
I would expect a powerpc64 randconfig to say
CONFIG_64BIT=y
Am I just confused?
Hi Randy,
Sorry for the trouble, the name of randconfig here is wrong,
it didn't set CONFIG_64BIT=y, it should be powerpc-randconfig-r001-xxx
Also, using (Arnd's) crosstools, the compiler for powerpc64 shows up
as powerpc64-linux-ld, not as powerpc-linux-ld.
Is that different for the 0day toolchains?
we'll check CONFIG_64BIT to choose the proper toolchain in reproduce
script
"https://raw.githubusercontent.com/intel/lkp-tests/master/sbin/make.cross"
Best Regards,
