[PATCH 00/17] Add automatic memory-leak detection to U-Boot tests
by Simon Glass 16 Mar '26

16 Mar '26

From: Simon Glass <sjg(a)chromium.org> This series adds built-in heap-leak detection that can be enabled with a single flag. It snapshots every in-use heap chunk before each test and reports any new allocations left behind afterwards, with full caller backtraces. Usage at the U-Boot command line: => ut -L dm dm_test_acpi_bgrt Test: acpi_bgrt: acpi.c Leak: 2 allocs 14a5c5c0 110 stdio_clone:230 <-vidconsole_post_probe:961 14a5c6d0 b0 map_to_sysmem:210 <-video_post_probe:823 Or via pytest: ./test/py/test.py -B sandbox --leak-check -k dm An interactive 'malloc leak' command is also provided for investigating leaks at the command line. The initial scan found 90 leaking test runs across 7 distinct bugs in SCMI, PMIC, SPI, PCI, ACPI and video subsystems, all fixed in this series. Simon Glass (17): kbuild: Use relative paths in generated .incbin directives blk: Return error from blk_get_devnum_by_uclass_idname() sandbox: Return -ENOMEM when os_map_file() fails vbe: Propagate probe errors from vbe_get_blk() malloc: Add heap-snapshot leak-checking functions test: Add memory leak checking option to ut command test: Show leaked allocations with ut -L test: Reset malloc backtrace collection before each test cmd: malloc: Add leak subcommand test: py: Add --leak-check option to pytest firmware: scmi: Fix memory leak in protocol list discovery power: pmic: Fix register leak in I2C PMIC emulator mtd: spi: Fix device name leak in sandbox SPI flash emulator pci: Fix PCI regions array leak on device removal test: dm: Fix memory leaks in ACPI DP tests dm: acpi: Fix memory leaks in ACPI item tracking and tests video: Fix map_to_sysmem() leak in show_splash() arch/sandbox/cpu/os.c | 2 +- boot/vbe_common.c | 11 +- cmd/Kconfig | 10 ++ cmd/blkmap.c | 8 +- cmd/malloc.c | 65 ++++++++ common/dlmalloc.c | 254 +++++++++++++++++++++++++++++ disk/part.c | 23 ++- doc/develop/malloc.rst | 68 +++++++- drivers/block/blk-uclass.c | 19 ++- drivers/block/blk_legacy.c | 3 +- drivers/core/acpi.c | 6 + drivers/firmware/scmi/base.c | 1 + drivers/mtd/spi/sandbox.c | 1 + drivers/pci/pci-uclass.c | 11 ++ drivers/power/pmic/i2c_pmic_emul.c | 11 ++ drivers/video/video-uclass.c | 1 + include/blk.h | 24 ++- include/malloc.h | 111 +++++++++++++ include/test/test.h | 2 + scripts/Makefile.lib | 11 +- test/boot/luks.c | 15 +- test/cmd/malloc.c | 52 ++++++ test/cmd_ut.c | 8 +- test/dm/acpi.c | 6 + test/dm/acpi_dp.c | 5 + test/py/conftest.py | 3 + test/py/tests/test_ut.py | 6 +- test/test-main.c | 24 +++ 28 files changed, 710 insertions(+), 51 deletions(-) -- 2.43.0 base-commit: cb53f60f48853713f398b86a12702304c82bdde7 branch: memb

[PATCH 00/20] buildman: Add distributed builds
by Simon Glass 16 Mar '26

16 Mar '26

From: Simon Glass <sjg(a)chromium.org> This series adds distributed build support to buildman, allowing board builds to be spread across a pool of remote machines over SSH. The first few patches prepare Builder for distributed use: adding parameters for custom thread classes, signal handling, lazy worktree setup, and splitting build_boards() so remote workers can queue boards incrementally. The machine module probes remote hosts over SSH to collect their capabilities (CPUs, memory, load, toolchains) and manages toolchain version checking and fetching. The worker module runs on remote machines in --worker mode, accepting JSON commands on stdin and streaming results on stdout. It reuses Builder and BuilderThread with a custom subclass that sends results over the SSH pipe instead of writing to disk. The boss module manages SSH connections to workers, handling startup, source push via git, demand-driven board dispatch, result collection with timeouts, and clean shutdown on Ctrl-C. The wire-up patch connects everything through control.py with --dist, --use-machines, and --no-local flags. Simon Glass (20): u_boot_pylib: Add stdin_data support to run_pipe() u_boot_pylib: Support passing modules to run_test_suites() buildman: Remove unused imports from builder.py buildman: Fix pylint warnings in test_builder.py buildman: Fix import order in control.py buildman: Initialise _timestamps to an empty deque buildman: Add thread_class param to Builder buildman: Add handle_signals param to Builder buildman: Add lazy thread setup to Builder buildman: Split build_boards() into two methods buildman: Add distributed-build attributes to Builder buildman: Cache the kconfig-changed check per commit buildman: Add dynamic job-count setting buildman: Pass NPROC to make for LTO parallelism buildman: Add remote machine probing for distributed builds buildman: Install toolchains on remote machines buildman: Add worker mode for distributed builds buildman: Add boss module for driving remote workers buildman: Wire up distributed builds with WorkerPool buildman: Document distributed builds in the README tools/buildman/boss.py | 1507 ++++++++++++++++++ tools/buildman/bsettings.py | 10 +- tools/buildman/builder.py | 228 ++- tools/buildman/builderthread.py | 94 +- tools/buildman/buildman.rst | 132 ++ tools/buildman/cmdline.py | 30 + tools/buildman/control.py | 313 +++- tools/buildman/func_test.py | 9 +- tools/buildman/machine.py | 923 +++++++++++ tools/buildman/main.py | 6 + tools/buildman/test.py | 3 + tools/buildman/test_boss.py | 2645 +++++++++++++++++++++++++++++++ tools/buildman/test_builder.py | 109 +- tools/buildman/test_machine.py | 1080 +++++++++++++ tools/buildman/test_worker.py | 896 +++++++++++ tools/buildman/worker.py | 985 ++++++++++++ tools/u_boot_pylib/command.py | 13 +- tools/u_boot_pylib/test_util.py | 49 +- 18 files changed, 8877 insertions(+), 155 deletions(-) create mode 100644 tools/buildman/boss.py create mode 100644 tools/buildman/machine.py create mode 100644 tools/buildman/test_boss.py create mode 100644 tools/buildman/test_machine.py create mode 100644 tools/buildman/test_worker.py create mode 100644 tools/buildman/worker.py -- 2.43.0 base-commit: cb53f60f48853713f398b86a12702304c82bdde7 branch: bmt

[PATCH 00/19] test: Fix pytest inter-test side effects
by Simon Glass 14 Mar '26

14 Mar '26

From: Simon Glass <sjg(a)chromium.org> Several pytest tests leave behind state that breaks later tests in the same session. This series fixes memory leaks, stale environment variables, dangling pointers, EFI log pollution and bootstage exhaustion, and adds a 'restart' marker for tests that restart U-Boot. It also adds --malloc-dump support for debugging heap issues.

[PATCH 0/4] pickman: Improve subtree-update and error handling
by Simon Glass 05 Mar '26

05 Mar '26

From: Simon Glass <sjg(a)chromium.org> Fix several issues with pickman's subtree update handling: resolve ambiguous checkout when multiple remotes share a branch name, add agent-based merge conflict resolution for subtree updates, fix push_branch() to properly propagate failures, and handle GitLab connection errors gracefully in step/poll commands. Also replace some broad Exception catches.
