We've found that these four utilities have been very useful in debugging boot issues; dropbear, netcat and rsync for remote access / file transfer, and ethtool for network-device firmware management. However, if we want to keep the defconfig as minimal as possible (rather than the configuration that I've assumed users will generally need), we can remove these. Regards, Jeremy

Because of the firmware lines, I thought that it was for some specific hardware. It would be better to take qemu_ppc64_pseries_defconfig and add the petitboot-specific things. I'd also name it qemu_ppc64_pseries_petitboot_defconfig to make this explicit. Or alternatively, petitboot_qemu_ppc64_pseries_defconfig. > >>> --- /dev/null >>> +++ b/configs/powerpc64_petitboot_defconfig >>> @@ -0,0 +1,17 @@ >>> +BR2_powerpc64=y >>> +BR2_GENERATE_LOCALE="en_US.UTF-8" >>> +BR2_ROOTFS_DEVICE_CREATION_DYNAMIC_EUDEV=y >>> +BR2_TARGET_GENERIC_GETTY_PORT="hvc0" >>> +BR2_PACKAGE_BUSYBOX_SHOW_OTHERS=y >>> +BR2_PACKAGE_LINUX_FIRMWARE=y >>> +BR2_PACKAGE_LINUX_FIRMWARE_BNX2X=y >>> +BR2_PACKAGE_LINUX_FIRMWARE_CXGB4=y >>> +BR2_PACKAGE_NCURSES_WCHAR=y >> >> Is this needed? > > Yes, we need this to display boot labels that contain non-ASCII > characters.

Yes, we try to have minimal defconfigs. It would also be nice to create board/qemu/ppc64-pseries/readme-petitboot.txt that explains how you can run this defconfig. I guess petitboot takes some kind of configuration file that specifies what you're going to boot into. It would be nice to have in the readme an example of how you can boot into another buildroot image (e.g. qemu_ppc64_pseries_defconfig). Regards, Arnout
