[PATCH 0/4] ACPI fixes
by Simon Glass 20 Aug '25

20 Aug '25

From: Simon Glass <sjg(a)chromium.org> This series collects a few fix-ups for the recent BGRT series and tweaks the ACPI tables to use U-Boot as the 'creator' of the tables. It also adds a new logo for U-Boot (with text below). Simon Glass (4): tools: Add the logo with text under it acpi: Use the logo with text underneath acpi: Check ACPI revision before accessing XSDT acpi: Use the U-Boot ACPI ID and version arch/x86/lib/acpi_nhlt.c | 2 +- arch/x86/lib/acpi_table.c | 2 +- include/acpi/acpi_table.h | 5 +-- lib/acpi/acpi.c | 8 +++-- lib/acpi/acpi_table.c | 2 +- lib/acpi/bgrt_image.bmp | Bin 43926 -> 56574 bytes test/dm/acpi.c | 58 +++++++++++++++++++------------ tools/logos/u_boot_logo_text.svg | Bin 0 -> 10733 bytes 8 files changed, 45 insertions(+), 32 deletions(-) create mode 100644 tools/logos/u_boot_logo_text.svg -- 2.43.0 base-commit: 5659b7adcb906a50d740ca68d3fc458172b9682c branch: bgr

[PATCH v2 00/18] efi: Move towards the EFI app booting EFI applications
by Simon Glass 20 Aug '25

20 Aug '25

From: Simon Glass <sjg(a)chromium.org> This series adds various new features to the EFI app, mostly by moving code over from the EFI loader implementation. In particular it adds support for the efidebug command (with only a subset of subcommands so far). The main approach is to make use of the system table (for both the app and the loader) instead of directly calling EFI-loader code. It also includes a few fixes, which likely have no effect but will help to avoid confusion in future. Changes in v2: - Mention the 'dh' subcommand - Mention that 'order' allows the boot order to be changed - Mention the eficonfig command and the underlying UEFI firmware Simon Glass (18): efi: Add missing break statements in dp_size() efi: Add missing break to dp_fill() efi: Update path_uefi() to avoid allowed_unaligned() efi: app: Support the efidebug command efi: app: Support efidebug memmap efi: app: Support efidebug show tables efi: app: Provide easy access to runtime services efi: Move a few helper functions into the common efi/ dir efi: Move some load-options handling into the common dir efi: Move FDT and global-variable GUIDs to common files efi: app: Implement efidebug boot dump efi: app: Find the device-path-to-text protocol on startup efi: app: Implement %pD in the app efi: Move efi_string utilities to the common directory efi: app: Use the same efi_free_pool() signature as loader efi: Move efi_load_option_dp_join() to a common file efi: app: Support efidebug boot add, rm and order efi: doc: Add documentation for efidebug command in the app cmd/Kconfig | 5 +- cmd/efidebug.c | 43 +++++++-- doc/develop/uefi/u-boot_on_efi.rst | 24 +++++ include/efi.h | 20 +++++ include/efi_loader.h | 11 --- lib/efi/Kconfig | 12 ++- lib/efi/Makefile | 3 + lib/efi/device_path.c | 20 +++-- lib/efi/helper.c | 88 +++++++++++++++++++ .../efi_load_options.c => efi/load_options.c} | 0 lib/{efi_loader/efi_string.c => efi/string.c} | 0 lib/efi_client/efi.c | 24 ++++- lib/efi_client/efi_app.c | 9 ++ lib/efi_client/efi_vars.c | 23 +++-- lib/efi_loader/Kconfig | 7 -- lib/efi_loader/Makefile | 2 - lib/efi_loader/efi_boottime.c | 7 +- lib/efi_loader/efi_helper.c | 77 ---------------- 18 files changed, 252 insertions(+), 123 deletions(-) create mode 100644 lib/efi/helper.c rename lib/{efi_loader/efi_load_options.c => efi/load_options.c} (100%) rename lib/{efi_loader/efi_string.c => efi/string.c} (100%) -- 2.43.0 base-commit: 5659b7adcb906a50d740ca68d3fc458172b9682c branch: loadq2

[PATCH 00/15] test: Improvements to make check et al
by Simon Glass 19 Aug '25

19 Aug '25

From: Simon Glass <sjg(a)chromium.org> It is helpful to be able to run 'make qcheck' to run a subset of the tests in a short time. However this has not always been reliable. Since this feature is not tested in CI it can sometimes break. Now that things are working correctly, add it the various 'make check' combinations to CI, so they will remain functional.

From: Simon Glass <sjg(a)chromium.org> The 'smbios' command has its own code for parsing SMBIOS tables. There in also lib/smbios-parser.c which parses tables, although only version 2.
