Nothing changed, but rebasing. # Summary ======= 'UpdateCapsule' is one of runtime services defined in UEFI specification and its aim is to allow a caller (OS) to pass information to the firmware, i.e. U-Boot. This is mostly used to update firmware binary on devices by instructions from OS. While 'UpdateCapsule' is a runtime services function, it is, at least initially, supported only before exiting boot services alike other runtime functions, [Get/]SetVariable. This is because modifying storage which may be shared with OS must be carefully designed and there is no general assumption that we can do it. Therefore, we practically support only "capsule on disk"; any capsule can be handed over to UEFI subsystem as a file on a specific file system. In this patch series, all the related definitions and structures are given as UEFI specification describes, and basic framework for capsule support is provided. Currently supported is * firmware update (Firmware Management Protocol or simply FMP) Most of functionality of firmware update is provided by FMP driver and it can be, by nature, system/platform-specific. So you can and should implement your own FMP driver(s) based on your system requirements. Under the current implementation, we provide two basic but generic drivers with two formats: * FIT image format (as used in TFTP update and dfu) * raw image format It's totally up to users which one, or both, should be used on users' system depending on user requirements. Quick usage =========== 1. You can create a capsule file with the following host command: $ mkeficapsule [--fit | --raw ] 2. Put the file under: /EFI/UpdateCapsule of UEFI system partition 3. Specify firmware storage to be updated in "dfu_alt_info" variable (Please follow README.dfu for details.) ==> env set dfu_alt_info '...' 4. After setting up UEFI's OsIndications variable, reboot U-Boot: OsIndications <= EFI_OS_INDICATIONS_FILE_CAPSULE_DELIVERY_SUPPORTED Patch structure =============== Patch#1-#4,#12: preparatory patches Patch#5-#11,#13: main part of implementation Patch#14-#15: utilities Patch#16-#17: pytests [1] https://git.linaro.org/people/takahiro.akashi/u-boot.git efi/capsule Prerequisite patches ==================== In this version, the DFU change by Heinrich[2] is, at least temporarily, not a prerequisite due to the discussions[3]. [2] https://lists.denx.de/pipermail/u-boot/2020-July/420950.html [3] https://lists.denx.de/pipermail/u-boot/2020-August/424716.html Test ==== * passed all the pytests which are included in this patch series on sandbox build locally. Please note that the capsule pytest itself won't be run in the CI partly because some specific configuration for sandbox build is required and partly because there is a problem with virt-make-fs. See test_efi_capsule_firmware.py. Issues ====== * Timing of executing capsules-on-disk Currently, processing a capsule is triggered only as part of UEFI subsystem initialization. This means that, for example, firmware update, may not take place at system booting time and will potentially be delayed until a first call of any UEFI functions. => See patch#5 for my proposal * A bunch of warnings like WARNING: Use 'if (IS_ENABLED(CONFIG...))' instead of '#if or #ifdef' where possible I don't think that fixing those improves anything. * Add a document in uefi.rst TODO's ====== (Won't be addressed in this series.) * capsule authentication * capsule dependency (dependency expression instruction set, or depex) * loading drivers in a capsule * handling RESET flag in a capsule and QeuryCapsuleCaps * full semantics of ESRT (EFI System Resource Table) * enabling capsule API at runtime * json capsule * recovery from update failure Changes ======= v6 RESEND (October 29, 2020) * rebased on v2021.01-rc1 v6 (September 7, 2020) * temporarily drop the prerequisite patch[2] * add a missing field (dependencies) in efi_api.h (but never used) (Patch#10) * add a missing field (image_capsule_support) and related definitions in efi_api.h (Patch#10, #15) * cosmetic changes on constant definitions in efi_api.h (Patch#10) * strict check for INVALID_PARAMETER at GET_IMAGE_INFO api (Patch#11,#13) * fix warnings in pytest (Patch#16,#17) v5 (August 3, 2020) * removed superfluous type conversion at dfu_write_from_mem_addr() (Patch#2) * introduced a common helper function, efi_create_indexed_name() (Patch#6,#7,#8) * use efi_[get|set]_variable_int(), if necessary, with READ_ONLY (Patch#7,#8) * return EFI_UNSUPPORTED at Patch#7 * changed the word, number, to 'index' (Patch#7,#8) * removed 'ifdef CONFIG_EFI_CAPSULE_ON_DISK' from a header (Patch#8) * initialize 'CapsuleLast' in efi_init_obj_list() (Patch#7,#8) * added 'const' qualifier for filename argument at efi_capsule_[read|delete]_file() (Patch#8) v4 (July 22, 2020) * rebased to Heinrich's current efi-2020-10 * rework dfu-related code to align with Heinrich's change (Patch#1,#3) * change a type of 'addr' argument from int to 'void *' per Sughosh's comment (Patch#2-#3,#11-#12) * rework/simplify pytests (Patch#15-#16) - utilize virt-make-fs - drop Test Case 1 (updating U-Boot environment data) - remove useless definitions (MNT_PNT, EFI_CAPSULE_IMAGE_NAME) - apply autopep8 v3 (July 10, 2020) * rebased to Heinrich's current efi-2020-10-rc1 * refactor efi_firmware_[fit|raw]_get_image_info() (patch#11,#13) v2 (June 17, 2020) * rebased to v2020.07-rc4 * add preparatory patches for dfu (Patch#1-#5, #12) * rework FIT capsule driver to utilize dfu_alt_info instead of CONFIG_xxx (patch#11) * extend get_image_info() to correspond to dfu_alt_info (patch#11) * add a 'raw binary' capsule support (patch#13, #17) * allow multiple capsule formats (with different GUIDs) to be installed (patch#11, #13) * extend mkeficapsule command to accept additional parameters, like version/index/hardware instance for a capsule header info.
