[PATCH 00/32] patman: Add multi-upstream support
by Simon Glass 26 Feb '26

26 Feb '26

From: Simon Glass <simon.glass(a)canonical.com> Add support for associating each series with an upstream remote, so that patman can automatically select the correct patchwork server, sendemail identity, To address and send options. This avoids having to remember which settings to use for each project. The series includes a v5 schema migration to add the necessary columns, accessor functions, command-line wiring, and documentation for the multi-upstream workflow. Simon Glass (32): patman: Expand the prep_series() comment patman: Reject database versions newer than supported patman: Add upstream and send settings to the database schema patman: Add an upstream column to the series table patman: Warn about series with no upstream after migration patman: Auto-detect upstream for series during migration patman: Show upstream in series list patman: Add set-upstream command for series patman: Associate patchwork projects with upstreams patman: Add upstream parameter to project_set() and project_get() patman: Add get_series_upstream() helper patman: Wire up per-upstream patchwork project in commands patman: Add patchwork list command patman: Make remote a required positional for patchwork project commands patman: Group remotes by project in patchwork list patman: Allow specifying project when adding an upstream patman: Rename -u/--use-commit to -1/--use-first-commit patman: Add per-upstream patchwork URL patman: Allow setting the upstream when adding a series patman: Add 'ls' and 'list' aliases for list subcommands patman: Add per-upstream send settings to the database patman: Support sendemail identity and series-to in the send path patman: Wire up per-upstream send settings in commands patman: Add an 'upstream set' command to update settings patman: Use notice() for database migration messages patman: Add header and tidy columns in upstream list patman: Update series description when adding a new version patman: Improve send feedback and upstream list formatting patman: Improve autolink wait with progress and backoff patman: Filter out AI co-developer tags from patches patman: Update series description on scan patman: Document multi-upstream setup tools/patman/cmdline.py | 72 +++++- tools/patman/control.py | 89 +++++++- tools/patman/cser_helper.py | 79 ++++++- tools/patman/cseries.py | 246 ++++++++++++++++++--- tools/patman/database.py | 292 +++++++++++++++++++++--- tools/patman/patchstream.py | 7 +- tools/patman/patman.rst | 167 ++++++++++++++ tools/patman/send.py | 25 ++- tools/patman/series.py | 3 +- tools/patman/test_common.py | 1 + tools/patman/test_cseries.py | 405 ++++++++++++++++++++++++++++++---- tools/u_boot_pylib/gitutil.py | 5 +- 12 files changed, 1251 insertions(+), 140 deletions(-) -- 2.43.0 base-commit: 0d02e154c4d4b861094ab3a1d389eb7530d6b313 branch: patg

[PATCH 00/16] pickman: Support monitoring and fixing pipeline failures
by Simon Glass 22 Feb '26

22 Feb '26

From: Simon Glass <simon.glass(a)canonical.com> This series contains three groups of improvements to pickman: Refactoring (patches 1-8): Clean up the codebase by splitting large functions into smaller helpers, adding test coverage for prepare_apply(), extracting a run_agent_collect() helper to remove duplicated agent-streaming code, and switching to tools.read/write_file() for file I/O. Subtree handling (patches 9-10): Teach pickman to detect and handle dts/upstream subtree merges, and process subtree updates even when the maximum number of MRs is reached. Pipeline fixes (patches 11-16): Add infrastructure and logic for automatically diagnosing and fixing CI pipeline failures using a Claude agent, including GitLab API helpers, database tracking, null-byte stripping in job logs, and a retry/comment system. Simon Glass (16): pickman: Drop unnecessary f-string prefixes in do_rewind() pickman: Refactor do_rewind() into smaller helpers pickman: Refactor do_next_merges() into smaller helpers pickman: Refactor decompose_mega_merge() into smaller helpers pickman: Refactor handle_already_applied() into smaller helpers pickman: Add tests for prepare_apply() pickman: Refactor the initial part of prepare_apply() pickman: Handle dts/upstream subtree merges automatically pickman: Create a function to run an agent pickman: Use tools for file I/O pickman: Use tools for file I/O in tests pickman: Add a database table to track pipeline fixes pickman: Add pipeline helpers to gitlab_api pickman: Support automatically fixing pipeline failures pickman: Process subtree updates even at max MRs pickman: Strip null bytes from CI job logs tools/pickman/README.rst | 81 ++ tools/pickman/__main__.py | 6 + tools/pickman/agent.py | 237 ++++- tools/pickman/control.py | 972 +++++++++++++++----- tools/pickman/database.py | 65 +- tools/pickman/ftest.py | 1661 ++++++++++++++++++++++++++++++++--- tools/pickman/gitlab_api.py | 78 +- 7 files changed, 2744 insertions(+), 356 deletions(-) -- 2.43.0 base-commit: c42396807e2c92a1f87b9d671e2e09c7bf13caf2 branch: picke

[PATCH 00/13] ulib: Enable the Rust demo on more architectures
by Simon Glass 20 Feb '26

20 Feb '26

From: Simon Glass <simon.glass(a)canonical.com> The Rust ulib demo currently only builds on x86_64. This series extends it to x86 (32-bit), RISC-V 64 and ARM64, for both QEMU and EFI targets. Along the way it fixes a rustc jobserver warning (MAKEFLAGS leak) and a linker crash on aarch64 caused by a Rust null-pointer-dereference check emitting an undefined panic symbol. Simon Glass (13): ulib: x86: Disable regparm when Rust examples are enabled disk: part_efi: Check the block size in part_test_efi() ulib: Extract common example build rules for demo ulib: Add Rust demo example ulib: x86: Add Rust demo for qemu-x86_64_nospl ulib: x86: Add 32-bit Rust target support ulib: x86: Enable Rust demo for qemu-x86 ulib: riscv: Enable Rust demo for qemu-riscv64 ulib: riscv: Add Rust demo test for qemu-riscv64 ulib: x86: Enable Rust demo for efi-x86_app64 ulib: arm64: Enable Rust demo for efi-arm_app64 ulib: riscv: Enable Rust demo for efi-riscv_app64 ulib: arm64: Enable Rust demo for qemu_arm64 arch/x86/Kconfig | 11 +- arch/x86/cpu/i386/setjmp.S | 2 + arch/x86/dts/u-boot.dtsi | 18 ++++ configs/efi-arm_app64_defconfig | 1 + configs/efi-riscv_app64_defconfig | 1 + configs/efi-x86_app64_defconfig | 1 + configs/qemu-riscv64_defconfig | 1 + configs/qemu-x86_64_nospl_defconfig | 1 + configs/qemu-x86_defconfig | 1 + configs/qemu_arm64_defconfig | 1 + disk/part_efi.c | 11 +- examples/Kconfig | 13 +++ examples/ulib/rust_demo.rs | 55 ++++++++++ scripts/Makefile.ulib-example | 81 ++++++++++++--- test/py/tests/test_ulib.py | 155 ++++++++++++++++++++++++++++ 15 files changed, 332 insertions(+), 21 deletions(-) create mode 100644 examples/ulib/rust_demo.rs -- 2.43.0 base-commit: 3b07f0d65d65584140eeffb16447175f9e230397 branch: ulibd

[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. Simon Glass (13): ulib: Add MAINTAINERS entry ulib: Use cross-toolchain objcopy for symbol redefinition examples: ulib: Support both sandbox and linked-in demo ulib: Make shared-lib deps conditional on ULIB_SHARED_LIB examples: ulib: Build shared-linked binaries only when .so is available efi: Allow runtime relocation in library mode ulib: Replace CONFIG_ULIB_JUMP_TO_MAIN with runtime ulib_has_main() Makefile: Extract u-boot-link helper for reuse x86: binman: Extract common ROM entries into a template x86: ulib: Add build infrastructure for example/ x86: ulib: Add demo.rom and enable examples for qemu-x86 Makefile: Only run standalone ulib examples for sandbox x86: ulib: Add pytest for demo.rom under QEMU Kconfig | 9 ---- MAINTAINERS | 11 +++++ Makefile | 28 ++++++++---- arch/x86/Makefile | 32 +++++++++++++ arch/x86/dts/u-boot.dtsi | 82 +++++++++++++++++++++------------ common/board_f.c | 2 +- common/board_r.c | 18 +++++++- configs/qemu-x86_defconfig | 1 + examples/Makefile | 4 ++ examples/ulib/Kbuild | 6 +++ examples/ulib/demo.c | 87 +++++++++++++++++++++--------------- examples/ulib/demo_helper.c | 5 +++ examples/ulib/rules.mk | 9 ++-- include/init.h | 11 +++++ lib/efi_loader/efi_runtime.c | 4 -- scripts/build_api.py | 18 +++++--- test/py/tests/test_ulib.py | 40 +++++++++++++++-- 17 files changed, 266 insertions(+), 101 deletions(-) create mode 100644 examples/ulib/Kbuild -- 2.43.0 base-commit: 3e9503f56997e202451c5b1b4308f34ef2c5fc79 branch: uliba

[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. Simon Glass (8): dm: Fix linker list alignment for ll_entry_get() part_find: Fix PARTITION_TYPE_GUID dependency warning boot: Add BLS Type #1 entry parser boot: Add BLS Type #1 bootmethod test: Add bootflow test for BLS bootmethod pxe: Support multiple initrd files using alist bls: Add 'fit' field for FIT image support doc: bls: Update for FIT and multi-initrd support arch/sandbox/dts/test.dts | 7 + boot/Kconfig | 38 ++++ boot/Makefile | 1 + boot/bls_parse.c | 303 +++++++++++++++++++++++++ boot/bootflow.c | 1 + boot/bootmeth_bls.c | 457 ++++++++++++++++++++++++++++++++++++++ boot/pxe_parse.c | 64 +++++- boot/pxe_utils.c | 114 ++++++++-- cmd/Kconfig | 2 +- doc/usage/bls.rst | 158 +++++++++++++ doc/usage/index.rst | 1 + include/bls.h | 103 +++++++++ include/bootflow.h | 2 + include/linker_lists.h | 3 +- include/pxe_utils.h | 5 +- test/boot/Makefile | 1 + test/boot/bls_parse.c | 200 +++++++++++++++++ test/boot/bootflow.c | 54 +++++ test/boot/pxe.c | 12 +- test/py/img/bls.py | 70 ++++++ test/py/tests/test_ut.py | 2 + 21 files changed, 1564 insertions(+), 34 deletions(-) create mode 100644 boot/bls_parse.c create mode 100644 boot/bootmeth_bls.c create mode 100644 doc/usage/bls.rst create mode 100644 include/bls.h create mode 100644 test/boot/bls_parse.c create mode 100644 test/py/img/bls.py -- 2.43.0 base-commit: d81d158208c9baf4ad093b3c8d74c37f84f6f268 branch: boob
