commit: 259149cf7c3c6195e6199e045ca988c31d081cab powerpc/32s: Only build hash
code when CONFIG_PPC_BOOK3S_604 is selected
date: 4 weeks ago
config: powerpc64-randconfig-r013-20210227 (attached as .config)
ktr/lkp, this is a PPC32 .config file that is attached, not PPC64.
Also:
compiler: powerpc-linux-gcc (GCC) 9.3.0
...
I do see this build error:
powerpc-linux-ld: arch/powerpc/boot/wrapper.a(decompress.o): in function
`partial_decompress':
decompress.c:(.text+0x1f0): undefined reference to `__decompress'
when either
CONFIG_KERNEL_LZO=y
or
CONFIG_KERNEL_LZMA=y
but the build succeeds when either
CONFIG_KERNEL_GZIP=y
or
CONFIG_KERNEL_XZ=y
I guess that is due to arch/powerpc/boot/decompress.c doing this:
#ifdef CONFIG_KERNEL_GZIP
# include "decompress_inflate.c"
#endif
#ifdef CONFIG_KERNEL_XZ
# include "xz_config.h"
# include "../../../lib/decompress_unxz.c"
#endif
It would be nice to require one of KERNEL_GZIP or KERNEL_XZ
to be set/enabled (maybe unless a uImage is being built?).
Can you test by

?
