The native version of grub-efi only installs the tools /usr/bin/grub-editenv /usr/bin/grub-mkimage to sysroots-components/, but equivalent tools are already provided by grub-native, the difference on x86_64 being 4 hardwired paths in grub-mkimage (values taken from grub-native): LOCALEDIR = $TMPDIR/work/x86_64-linux/grub-native/2.04-r0/recipe-sysroot-native/usr/share/locale GRUB_DATADIR = $TMPDIR/work/x86_64-linux/grub-native/2.04-r0/recipe-sysroot-native/usr/share GRUB_LIBDIR = $TMPDIR/work/x86_64-linux/grub-native/2.04-r0/recipe-sysroot-native/usr/lib GRUB_SYSCONFDIR = $TMPDIR/work/x86_64-linux/grub-native/2.04-r0/recipe-sysroot-native/etc If grub-native and grub-efi-native are built with the following patch --- grub-2.04.orig/configure.ac +++ grub-2.04/configure.ac @@ -1980,10 +1980,10 @@ grub_libdir="$(eval echo "$libdir")" grub_localedir="$(eval echo "$localedir")" grub_datadir="$(eval echo "$datadir")" grub_sysconfdir="$(eval echo "$sysconfdir")" -AC_DEFINE_UNQUOTED(LOCALEDIR, "$grub_localedir", [Locale dir]) -AC_DEFINE_UNQUOTED(GRUB_LIBDIR, "$grub_libdir", [Library dir]) -AC_DEFINE_UNQUOTED(GRUB_DATADIR, "$grub_datadir", [Data dir]) -AC_DEFINE_UNQUOTED(GRUB_SYSCONFDIR, "$grub_sysconfdir", [Configuration dir]) +AC_DEFINE_UNQUOTED(LOCALEDIR, "/non-existent", [Locale dir]) +AC_DEFINE_UNQUOTED(GRUB_LIBDIR, "/non-existent", [Library dir]) +AC_DEFINE_UNQUOTED(GRUB_DATADIR, "/non-existent", [Data dir]) +AC_DEFINE_UNQUOTED(GRUB_SYSCONFDIR, "/non-existent", [Configuration dir]) the produced grub-editenv/grub-mkimage binaries become binary equivalent, assuming reproducible builds is active. Since the unpatched values of LOCALEDIR/GRUB_DATADIR/GRUB_LIBDIR/GRUB_SYSCONFDIR point to directories that are not expected to exist at runtime, they can be ignored. Therefore: * remove grub-efi-native and instead rely on the same tools from grub-native * replace references to grub-efi-native with grub-native * remove unused grub-efi-native security flags overrides (From OE-Core rev: 7044181df7487f047d175242f7ebbc3c35bf5402) Signed-off-by: Jacob Kroon <jacob.kroon@gmail.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
QEMU Emulation Targets ====================== To simplify development, the build system supports building images to work with the QEMU emulator in system emulation mode. Several architectures are currently supported in 32 and 64 bit variants: * ARM (qemuarm + qemuarm64) * x86 (qemux86 + qemux86-64) * PowerPC (qemuppc only) * MIPS (qemumips + qemumips64) Use of the QEMU images is covered in the Yocto Project Reference Manual. The appropriate MACHINE variable value corresponding to the target is given in brackets.
