The branch main has been updated by imp: URL: https://cgit.FreeBSD.org/src/commit/?id=599273f942b8dc6f957487bb28f36694dab9dad2 commit 599273f942b8dc6f957487bb28f36694dab9dad2 Author: Ahmad Khalifa <ahmadkhalifa570@gmail.com> AuthorDate: 2024-06-03 01:53:44 +0000 Commit: Warner Losh <imp@FreeBSD.org> CommitDate: 2024-09-20 14:45:10 +0000 Copy the new ia32 loader This handles copying in install-boot.sh and bsdinstall's bootconfig. install-boot.sh: make_esp_file now optionally takes extra arguments so it can copy multiple files. This is used by the amd64 release scripts. make_esp_device also takes an extra optional argument for efibootname. This is currently unused, but it can be used in the future to do something like: make_esp_device loader.efi bootx64 make_esp_device loader_ia32.efi bootia32 Reviewed by: imp Pull Request: https://github.com/freebsd/freebsd-src/pull/1098 --- release/amd64/make-memstick.sh | 7 ++++- release/amd64/mkisoimages.sh | 7 ++++- tools/boot/install-boot.sh | 52 +++++++++++++++++++++++++--------- usr.sbin/bsdinstall/scripts/bootconfig | 36 ++++++++++++++--------- 4 files changed, 72 insertions(+), 30 deletions(-) diff --git a/release/amd64/make-memstick.sh b/release/amd64/make-memstick.sh index 4c51d7d65af4..cbb80e971343 100755 --- a/release/amd64/make-memstick.sh +++ b/release/amd64/make-memstick.sh @@ -60,7 +60,12 @@ fi # Make an ESP in a file. espfilename=$(mktemp /tmp/efiboot.XXXXXX) -make_esp_file ${espfilename} ${fat32min} ${BASEBITSDIR}/boot/loader.efi +if [ -f "${BASEBITSDIR}/boot/loader_ia32.efi" ]; then + make_esp_file ${espfilename} ${fat32min} ${BASEBITSDIR}/boot/loader.efi bootx64 \ + ${BASEBITSDIR}/boot/loader_ia32.efi bootia32 +else + make_esp_file ${espfilename} ${fat32min} ${BASEBITSDIR}/boot/loader.efi +fi mkimg -s mbr \ -b ${BASEBITSDIR}/boot/mbr \ diff --git a/release/amd64/mkisoimages.sh b/release/amd64/mkisoimages.sh index 3cc7a6cc919e..245beb660c3f 100644 --- a/release/amd64/mkisoimages.sh +++ b/release/amd64/mkisoimages.sh @@ -64,7 +64,12 @@ if [ "$1" = "-b" ]; then espfilename=$(mktemp /tmp/efiboot.XXXXXX) # ESP file size in KB. espsize="2048" - make_esp_file ${espfilename} ${espsize} ${BASEBITSDIR}/boot/loader.efi + if [ -f "${BASEBITSDIR}/boot/loader_ia32.efi" ]; then + make_esp_file ${espfilename} ${espsize} ${BASEBITSDIR}/boot/loader.efi bootx64 \ + ${BASEBITSDIR}/boot/loader_ia32.efi bootia32 + else + make_esp_file ${espfilename} ${espsize} ${BASEBITSDIR}/boot/loader.efi + fi bootable="$bootable -o bootimage=i386;${espfilename} -o no-emul-boot -o platformid=efi" shift diff --git a/tools/boot/install-boot.sh b/tools/boot/install-boot.sh index 332756582137..217bf0ff1457 100755 --- a/tools/boot/install-boot.sh +++ b/tools/boot/install-boot.sh @@ -42,11 +42,10 @@ get_uefi_bootname() { } make_esp_file() { - local file sizekb loader device stagedir fatbits efibootname + local file sizekb device stagedir fatbits efibootname file=$1 sizekb=$2 - loader=$3 if [ "$sizekb" -ge "$fat32min" ]; then fatbits=32 @@ -58,8 +57,25 @@ make_esp_file() { stagedir=$(mktemp -d /tmp/stand-test.XXXXXX) mkdir -p "${stagedir}/EFI/BOOT" - efibootname=$(get_uefi_bootname) - cp "${loader}" "${stagedir}/EFI/BOOT/${efibootname}.efi" + + # Allow multiple files to be copied. + # We do this in pairs, e.g: + # make_esp_file ... loader1.efi bootx64 loader2.efi bootia32 + # + # If the second argument is left out, + # determine it automatically. + shift; shift # Skip $file and $sizekb + while [ !
