With zephyr v2.5.0, EFI binary support has been added for x86 board (64-bit mode).
To achieve this, an python tool[1] has been added to convert zephyr ELF file into an EFI appliable. But currently this does not work with Yocto cross-compilation env. This patch fix this issue and allow to build zephyr.efi Ref: [1]https://github.com/zephyrproject-rtos/zephyr/commit/928d31125f0b4eb28fe1cf3f3ad02b0ae071d7fd Signed-off-by: Naveen Saini <naveen.kumar.sa...@intel.com> --- ...ry-generation-issue-in-cross-compila.patch | 80 +++++++++++++++++++ .../zephyr-kernel/zephyr-kernel-src.inc | 1 + 2 files changed, 81 insertions(+) create mode 100644 recipes-kernel/zephyr-kernel/files/0001-x86-fix-efi-binary-generation-issue-in-cross-compila.patch diff --git a/recipes-kernel/zephyr-kernel/files/0001-x86-fix-efi-binary-generation-issue-in-cross-compila.patch b/recipes-kernel/zephyr-kernel/files/0001-x86-fix-efi-binary-generation-issue-in-cross-compila.patch new file mode 100644 index 0000000..fd6fc6b --- /dev/null +++ b/recipes-kernel/zephyr-kernel/files/0001-x86-fix-efi-binary-generation-issue-in-cross-compila.patch @@ -0,0 +1,80 @@ +From cfde3b1018c3151b6cc1fbe3e9e163d0aaf16954 Mon Sep 17 00:00:00 2001 +From: Naveen Saini <naveen.kumar.sa...@intel.com> +Date: Tue, 11 May 2021 13:46:39 +0800 +Subject: [PATCH] x86: fix efi binary generation issue in cross compilation env + +Set root directory for headers. + +Upstream-Status: Inappropriate [Cross-compilation specific] + +Signed-off-by: Naveen Saini <naveen.kumar.sa...@intel.com> +--- + arch/x86/zefi/zefi.py | 6 +++++- + boards/x86/ehl_crb/CMakeLists.txt | 1 + + boards/x86/qemu_x86/CMakeLists.txt | 1 + + boards/x86/up_squared/CMakeLists.txt | 1 + + 4 files changed, 8 insertions(+), 1 deletion(-) + +diff --git a/arch/x86/zefi/zefi.py b/arch/x86/zefi/zefi.py +index d3514391a8..b9eccbfa10 100755 +--- a/arch/x86/zefi/zefi.py ++++ b/arch/x86/zefi/zefi.py +@@ -106,7 +106,10 @@ def build_elf(elf_file): + # + We need pic to enforce that the linker adds no relocations + # + UEFI can take interrupts on our stack, so no red zone + # + UEFI API assumes 16-bit wchar_t +- cmd = [args.compiler, "-shared", "-Wall", "-Werror", "-I.", ++ ++ # Pass --sysroot path for cross compilation ++ sysrootarg = "--sysroot=" + args.sysroot ++ cmd = [args.compiler, "-shared", "-Wall", "-Werror", "-I.", sysrootarg, + "-fno-stack-protector", "-fpic", "-mno-red-zone", "-fshort-wchar", + "-Wl,-nostdlib", "-T", ldscript, "-o", "zefi.elf", cfile] + verbose(" ".join(cmd)) +@@ -145,6 +148,7 @@ def parse_args(): + parser.add_argument("-o", "--objcopy", required=True, help="objcopy to be used") + parser.add_argument("-f", "--elf-file", required=True, help="Input file") + parser.add_argument("-v", "--verbose", action="store_true", help="Verbose output") ++ parser.add_argument("-s", "--sysroot", required=True, help="Cross compilation --sysroot=path") + + return parser.parse_args() + +diff --git a/boards/x86/ehl_crb/CMakeLists.txt b/boards/x86/ehl_crb/CMakeLists.txt +index 0d572eff30..6a228107dc 100644 +--- a/boards/x86/ehl_crb/CMakeLists.txt ++++ b/boards/x86/ehl_crb/CMakeLists.txt +@@ -5,6 +5,7 @@ set_property(GLOBAL APPEND PROPERTY extra_post_build_commands + -c ${CMAKE_C_COMPILER} + -o ${CMAKE_OBJCOPY} + -f ${PROJECT_BINARY_DIR}/${CONFIG_KERNEL_BIN_NAME}.elf ++ -s ${SYSROOT_DIR} + $<$<BOOL:${CMAKE_VERBOSE_MAKEFILE}>:--verbose> + WORKING_DIRECTORY ${PROJECT_BINARY_DIR} + ) +diff --git a/boards/x86/qemu_x86/CMakeLists.txt b/boards/x86/qemu_x86/CMakeLists.txt +index 1131a5c7ce..489f17192b 100644 +--- a/boards/x86/qemu_x86/CMakeLists.txt ++++ b/boards/x86/qemu_x86/CMakeLists.txt +@@ -4,6 +4,7 @@ set_property(GLOBAL APPEND PROPERTY extra_post_build_commands + -c ${CMAKE_C_COMPILER} + -o ${CMAKE_OBJCOPY} + -f ${PROJECT_BINARY_DIR}/${CONFIG_KERNEL_BIN_NAME}.elf ++ -s ${SYSROOT_DIR} + $<$<BOOL:${CMAKE_VERBOSE_MAKEFILE}>:--verbose> + WORKING_DIRECTORY ${PROJECT_BINARY_DIR} + ) +diff --git a/boards/x86/up_squared/CMakeLists.txt b/boards/x86/up_squared/CMakeLists.txt +index 0eaa9753fc..2e8ce7cfbc 100644 +--- a/boards/x86/up_squared/CMakeLists.txt ++++ b/boards/x86/up_squared/CMakeLists.txt +@@ -5,6 +5,7 @@ set_property(GLOBAL APPEND PROPERTY extra_post_build_commands + -c ${CMAKE_C_COMPILER} + -o ${CMAKE_OBJCOPY} + -f ${PROJECT_BINARY_DIR}/${CONFIG_KERNEL_BIN_NAME}.elf ++ -s ${SYSROOT_DIR} + $<$<BOOL:${CMAKE_VERBOSE_MAKEFILE}>:--verbose> + WORKING_DIRECTORY ${PROJECT_BINARY_DIR} + ) +-- +2.17.1 + diff --git a/recipes-kernel/zephyr-kernel/zephyr-kernel-src.inc b/recipes-kernel/zephyr-kernel/zephyr-kernel-src.inc index 8c987bb..8d5f176 100644 --- a/recipes-kernel/zephyr-kernel/zephyr-kernel-src.inc +++ b/recipes-kernel/zephyr-kernel/zephyr-kernel-src.inc @@ -21,5 +21,6 @@ SRC_URI = "\ git://github.com/zephyrproject-rtos/libmetal.git;protocol=https;destsuffix=git/modules/hal/libmetal;name=libmetal \ git://github.com/zephyrproject-rtos/tinycrypt.git;protocol=https;destsuffix=git/modules/crypto/tinycrypt;name=tinycrypt \ file://0001-cmake-add-yocto-toolchain.patch \ + file://0001-x86-fix-efi-binary-generation-issue-in-cross-compila.patch \ " S = "${WORKDIR}/git" -- 2.17.1
