[PATCH 00/17] ulib: Add multi-arch demo and EFI app support
by Simon Glass 16 Feb '26

16 Feb '26

From: Simon Glass <simon.glass(a)canonical.com> This series extends the ulib demo to ARM64 and RISC-V64, following the existing x86 pattern. Each architecture re-links U-Boot with the example objects so the demo's main() overrides the weak default. RISC-V requires an additional prelink-riscv step to resolve GOT entries in the static PIE binary. EFI app builds are also supported on all three architectures, producing a demo-app.efi binary that can boot under QEMU with UEFI firmware. A build_api.py fix handles empty archives that appear in cross-compiled EFI builds. All new demos have pytests that boot under QEMU and verify the expected output. A new 'localqemu' pytest marker skips these tests in lab mode, since they launch their own QEMU rather than using the lab's managed U-Boot instance. This also updates the build-qemu script to support RISC-V. Simon Glass (17): ulib: Skip empty archives in build_api.py objcopy step ulib: Build the static test binary by default ulib: test: Add localqemu marker to skip tests in lab ulib: test: Detect clang instead of checking binaries ulib: Extract common example build rules for demo ulib: x86: Add demo pytest for qemu-x86_64_nospl ulib: arm: Add demo binary and examples for qemu_arm64 ulib: riscv: Add demo binary and examples for qemu-riscv64 ulib: efi: Use ulib_has_main() in efi_main() ulib: x86: Add demo-app.efi target for EFI app builds ulib: x86: Enable examples for efi-x86_app64 ulib: test: Add a pytest for efi-x86_app64 demo ulib: arm: Enable demo EFI binary for efi-arm_app64 ulib: riscv: Enable demo EFI binary for efi-riscv_app64 ulib: test: Add EFI demo pytest for arm64 ulib: test: Add EFI demo pytest for riscv64 ulib: scripts: Add RISC-V support to build-qemu Makefile | 3 + arch/arm/Makefile | 6 + arch/riscv/Makefile | 7 + arch/x86/Makefile | 31 +--- configs/efi-arm_app64_defconfig | 2 + configs/efi-riscv_app64_defconfig | 2 + configs/efi-x86_app64_defconfig | 2 + configs/qemu-riscv64_defconfig | 2 + configs/qemu-x86_64_nospl_defconfig | 2 + configs/qemu_arm64_defconfig | 2 + doc/develop/pytest/usage.rst | 9 ++ examples/ulib/Kbuild | 2 +- lib/efi_client/efi_main.c | 3 +- scripts/Makefile.ulib-example | 63 ++++++++ scripts/build-qemu | 23 ++- scripts/build_api.py | 6 + test/py/conftest.py | 15 ++ test/py/pytest.ini | 1 + test/py/tests/test_ulib.py | 237 ++++++++++++++++++++++++---- 19 files changed, 351 insertions(+), 67 deletions(-) create mode 100644 scripts/Makefile.ulib-example -- 2.43.0 base-commit: a0102ffa945d6a92b52167d11faa06a4e52edd31 branch: ulibb

[PATCH 00/13] ulib: Support building examples for x86
by Simon Glass 14 Feb '26

14 Feb '26

From: Simon Glass <simon.glass(a)canonical.com> This series extends ulib so that examples can be built and run on x86, not just sandbox. It refactors the demo to support both environments, extracts common binman ROM entries into a reusable template, adds build infrastructure for x86 examples, and includes a QEMU-based pytest for the resulting demo.rom image.

[PATCH 0/8] Add BLS Type #1 bootmethod with FIT and multi-initrd support
by Simon Glass 13 Feb '26

13 Feb '26

From: Simon Glass <simon.glass(a)canonical.com> Add a Boot Loader Specification (BLS) Type #1 bootmethod, enabling U-Boot to discover and boot from BLS entry files. This is used by Fedora, RHEL and other distributions. The series also extends PXE infrastructure to support multiple initrd files using an alist, with LMB-based memory allocation for placing subsequent initrds. The sysboot command gains the same LMB allocation support. Finally, a 'fit' field is added as a U-Boot extension to the BLS format, allowing entries to explicitly specify a FIT image path as an alternative to the 'linux' field. It also includes a fix for a long-standing linker-list bug, as well as a recently introduced Kconfig warning.

[PATCH 0/9] pickman: Improve handling of large merges and add rewind
by Simon Glass 12 Feb '26

12 Feb '26

From: Simon Glass <simon.glass(a)canonical.com> This series adds three improvements to pickman: - Increase the agent SDK buffer size from 1MB to 10MB to avoid fatal errors when processing large responses - Decompose mega-merges (e.g. "Merge branch 'next'") into individual sub-merge batches, so the agent processes them one at a time instead of being overwhelmed by hundreds of commits at once - Add a 'rewind' command for stepping the source position back by N merges, allowing a cherry-pick run to be retried from an earlier point It also tidies up some pylint warnings. Simon Glass (9): pickman: Fix line-too-long pylint warnings in ftest pickman: Extract build_applied_map() from execute_apply() pickman: Group named-tuple declarations together pickman: Rename error to err for local variables pickman: Return NextCommitsInfo from get_next_commits() pickman: Increase agent SDK buffer size to 10MB pickman: Extract find_unprocessed_commits() from get_next_commits() pickman: Decompose mega-merges into sub-merge batches pickman: Add rewind command for stepping backwards tools/pickman/__main__.py | 10 + tools/pickman/agent.py | 8 +- tools/pickman/control.py | 634 ++++++++++++++++++----- tools/pickman/database.py | 8 + tools/pickman/ftest.py | 990 +++++++++++++++++++++++++++++++++--- tools/pickman/gitlab_api.py | 22 +- 6 files changed, 1470 insertions(+), 202 deletions(-) -- 2.43.0 base-commit: 5d89c27ce319a80f582c75be05d2456c1262c065 branch: pickd

[PATCH 00/15] riscv: Add EFI-application support
by Simon Glass 12 Feb '26

12 Feb '26

From: Simon Glass <simon.glass(a)canonical.com> Add support for building and running U-Boot as a 64-bit RISC-V EFI application on top of UEFI firmware such as EDK2. This includes build system changes (linker script, build flags, object exclusions), runtime fixes (FDT relocation skip, global data pointer handling, OF_BOARD_FIXUP disable), timer support via the firmware FDT, board files and defconfig It also provides QEMU integration in the build-efi script so it is easy to try out.

[PATCH 00/12] x86: Add single 64-bit U-Boot without SPL for QEMU
by Simon Glass 11 Feb '26

11 Feb '26

From: Simon Glass <simon.glass(a)canonical.com> This series adds support for building a single 64-bit U-Boot binary with integrated 16-bit and 32-bit startup code, eliminating the need for SPL on platforms where RAM is available immediately (e.g. QEMU). The new start_from_32.S enters in 32-bit protected mode (from start16.S), builds identity-mapped page tables with 2MB pages, enables SSE and PAE, then transitions to 64-bit long mode before calling board_init_f(). Since the 64-bit binary is linked as PIE, the 16-bit startup objects cannot be linked into it directly. Instead they are linked into a separate 32-bit ELF and their sections are extracted to binary files for binman. Along the way this moves the x86 16-bit binary rules from the top-level Makefile into arch/x86/Makefile, and switches x86_64 to use MSR_FS_BASE for the global data pointer instead of a writable global variable. Tested on QEMU x86_64 - boots to the command prompt. The existing SPL-based qemu-x86_64 and 32-bit qemu-x86 builds are unaffected. Simon Glass (12): x86: Allow disabling the regparm calling-convention x86: Use MSR_FS_BASE for gd pointer on x86_64 efi: Cache gd->relocaddr for EFI runtime services x86: Move 16-bit binary rules to arch/x86/Makefile x86: Exclude X86_32BIT_INIT for 64-bit builds x86: Build 16-bit startup objects as 32-bit for x86_64 x86: Link 16-bit startup into separate 32-bit ELF x86: Add 32-to-64-bit startup code x86: Add qemu-x86_64_nospl defconfig x86: qemu: Enable MTRR setup for x86_64 no-SPL scripts: build-qemu: Add --no-spl option for x86_64 CI: Add test coverage for qemu-x86_64_nospl .azure-pipelines.yml | 3 + .gitlab-ci.yml | 6 + Makefile | 10 - arch/x86/Kconfig | 24 +- arch/x86/Makefile | 39 +++ arch/x86/config.mk | 2 + arch/x86/cpu/Makefile | 15 ++ arch/x86/cpu/i386/interrupt.c | 10 +- arch/x86/cpu/qemu/qemu.c | 4 +- arch/x86/cpu/start.S | 23 +- arch/x86/cpu/start_from_32.S | 248 ++++++++++++++++++ arch/x86/cpu/start_from_spl.S | 21 +- arch/x86/cpu/start_from_tpl.S | 19 +- arch/x86/cpu/u-boot-16bit.lds | 30 +++ arch/x86/cpu/x86_64/cpu.c | 2 + arch/x86/cpu/x86_64/misc.c | 12 +- arch/x86/dts/emulation-u-boot.dtsi | 2 +- arch/x86/include/asm/global_data.h | 26 +- board/emulation/qemu-x86/MAINTAINERS | 1 + configs/qemu-x86_64_nospl_defconfig | 82 ++++++ lib/efi_loader/efi_runtime.c | 19 +- scripts/build-qemu | 9 +- .../bin/travis-ci/conf.qemu-x86_64_nospl_na | 30 +++ .../u_boot_boardenv_qemu_x86_64_nospl_na.py | 14 + 24 files changed, 613 insertions(+), 38 deletions(-) create mode 100644 arch/x86/cpu/start_from_32.S create mode 100644 arch/x86/cpu/u-boot-16bit.lds create mode 100644 configs/qemu-x86_64_nospl_defconfig create mode 100644 test/hooks/bin/travis-ci/conf.qemu-x86_64_nospl_na create mode 100644 test/hooks/py/travis-ci/u_boot_boardenv_qemu_x86_64_nospl_na.py -- 2.43.0 base-commit: 06331d87ef4298638e64dab5a4d7f4ba2c19fdcb branch: qemv

[PATCH 0/4] Fix truetype bbox init and improve pager robustness
by Simon Glass 08 Feb '26

08 Feb '26

From: Simon Glass <simon.glass(a)canonical.com> Fix an uninitialised bbox in truetype_measure() and fix a severe performance regression in the pager. The pager falls back to character-by-character output because pager_post() cannot accept length-delimited strings from putsn().
