This binary can be booted with UEFI firmware and systemd-boot. No grub is needed and UEFI firmware and/or systemd-boot provide possibilities for boot menus. The uki binary can also be signed for UEFI secure boot so the secure boot extends from firmware to kernel and initrd. Binding secure boot to full userspace is then easier since for example kernel command line and initrd contain the support needed to mount encrypted dm-verity etc partitions, and/or create partitions on demand with systemd-repart using device specific TPM devices for encryption. Tested on qemuarm64-secureboot machine from meta-arm with changes to support secure boot. Slightly different configuration tested on multiple arm64 System Ready boards with UEFI firmware, real and firmware based TPM devices. Tested with ovmf firmware on x86_64 with selftests but without secure boot which seems to be harder to setup in ovmf. Sadly I see two wic selftests, wic.Wic2.test_rawcopy_plugin_qemu and wic.Wic2.test_expand_mbr_image, failing when executing all wic selftests on a build machine with zfs filesystem. Will investigate this further. The issue seems to be in mkfs.ext4 producing broken filesystem, and partially in the tests which don't run the correct rootfs file (.ext4 vs .wic). Will debug this further and it is IMO unrelated to these changes since they reproduce on pure master branch without this series. v7: add missing "ovmf" to runqemu argument to test_efi_plugin_plain_systemd_boot_qemu_x86 to fix boot hang v6: fixes wic refactoring botch which broken non-uki systemd-boot usage on genericarm64 reported by Ross Burton , added selftest to cover this wks usage on x86 and aarch64 v5: drop patch "image_types_wic.bbclass: set systemd-boot and os-release dependency for all archs" since systemd-boot does not support all architectures v4: handle missing runqemu variable from build config, add python3-pefile to fast ptest list v3: rebased, fixed and added more sefltests, removed wic plugin side uki support v2: https://lists.openembedded.org/g/openembedded-core/message/204090 Michelle Lin (1): uki.bbclass: add class for building Unified Kernel Images (UKI) Mikko Rapeli (7): wic bootimg-efi.py: keep timestamps and add debug prints wic bootimg-efi.py: change UKI support from wic plugin to uki.bbclass oeqa selftest uki.py: add tests for uki.bbclass oeqa selftest efibootpartition.py: add TEST_RUNQEMUPARAMS to runqemu oeqa selftest efibootpartition.py: remove systemd-boot from grub-efi test oeqa selftest wic.py: add TEST_RUNQEMUPARAMS to runqemu oeqa selftest wic.py: support UKIs via uki.bbclass meta-selftest/wic/test_efi_plugin.wks | 5 +- .../test_efi_plugin_plain_systemd-boot.wks | 5 + meta/classes-recipe/image_types_wic.bbclass | 3 +- meta/classes-recipe/uki.bbclass | 197 ++++++++++++++++++ .../oeqa/selftest/cases/efibootpartition.py | 11 +- meta/lib/oeqa/selftest/cases/uki.py | 138 ++++++++++++ meta/lib/oeqa/selftest/cases/wic.py | 124 +++++++++-- .../wic/canned-wks/efi-uki-bootdisk.wks.in | 3 + scripts/lib/wic/plugins/source/bootimg-efi.py | 183 +++++----------- 9 files changed, 511 insertions(+), 158 deletions(-) create mode 100644 meta-selftest/wic/test_efi_plugin_plain_systemd-boot.wks create mode 100644 meta/classes-recipe/uki.bbclass create mode 100644 meta/lib/oeqa/selftest/cases/uki.py create mode 100644 scripts/lib/wic/canned-wks/efi-uki-bootdisk.wks.in
