Yeah, this is related to the same change that broke arm64: http://lists.gnu.org/archive/html/grub-devel/2017-05/msg00043.html If ppc64le does not require any manual DMA cache synchronization, you could probably just add something like: diff --git a/include/grub/cache.h b/include/grub/cache.h index 1c98ce270..c99316e09 100644 --- a/include/grub/cache.h +++ b/include/grub/cache.h @@ -34,7 +34,8 @@ void EXPORT_FUNC(grub_arch_sync_caches) (void *address, grub_size_t len); #endif #ifndef GRUB_MACHINE_EMU -#if defined (__i386__) || defined (__x86_64__) +#if defined (__i386__) || defined (__x86_64__) || (defined (__PPC64__) && \ + defined (__LITTLE_ENDIAN__)) static inline void grub_arch_sync_dma_caches (volatile void *address __attribute__ ((unused)), grub_size_t len __attribute__ ((unused))) / Leif _______________________________________________ Grub-devel mailing list Grub-devel@gnu.org https://lists.gnu.org/mailman/listinfo/grub-devel
