Hi, This patches series implements support for xen.gz being a gzipped multiboot-capable PE binary rather than an ELF binary. The purpose of this is to allow the same xen.gz to be booted using BIOS, UEFI, and UEFI with Secure Boot verification just like it can be done with a Linux kernel. It also means that it is possible to enable Secure Boot while still retaining the flexibility of a full bootloader like GRUB2 - not currently possible when using xen.efi. This requires some (backwards-compatible) extensions to the multiboot2 protocol which will be sent in a separate series along with the GRUB changes which implement the extensions. Ross Ross Lagerwall (4): multiboot2: Advertise the load type x86: Add support for building a multiboot2 PE binary x86: Hand-edit coff flags to remove RELOCS_STRIPPED flag x86: Call Shim Verify in the multiboot2 path .gitignore | 1 + xen/Makefile | 1 + xen/arch/x86/Kconfig | 6 +++ xen/arch/x86/Makefile | 50 +++++++++++++++++++ xen/arch/x86/boot/head.S | 40 ++++++++++++++- xen/arch/x86/efi/efi-boot.h | 65 +++++++++++++++++++++++- xen/arch/x86/efi/set-coff-flags.c | 83 +++++++++++++++++++++++++++++++ xen/include/xen/multiboot2.h | 6 +++ 8 files changed, 250 insertions(+), 2 deletions(-) create mode 100644 xen/arch/x86/efi/set-coff-flags.c -- 2.43.0
