[PATCH 00/19] Enhanced command-line editing with undo/redo support
by Simon Glass 30 Jan '26

30 Jan '26

This series adds enhanced editing features to the U-Boot command line, including multi-level undo/redo, yank/paste, word navigation, and multiline editing support for the expo textedit widget. Key features: - Multi-level undo (Ctrl+Z) and redo (Ctrl+Shift+Z) with configurable depth via CONFIG_CMDLINE_UNDO_COUNT - Yank/paste killed text with Ctrl+Y - Word navigation with Ctrl+Left/Right arrows - Home/End key support in sandbox SDL console - Multiline editing mode where Ctrl+K kills to end of line (not buffer) and Home/End navigate within the current line The series also includes test infrastructure improvements, fixes a memory leak in expo text object destruction, and fixes a buildman bug with merge_config.sh path resolution when using work directories. Simon Glass (19): buildman: Fix merge_config.sh path when using work directories buildman: Add option to build then show summary test: Add ut_check_video() helper function test: Add video_compress_fb_() with message parameter test: Display message at top right during video test delay expo: Free gen.lines alist when destroying text objects expo: Read all available input to keep up with key repeat input: Add Ctrl+arrow key support for sandbox SDL console input: Add Home and End key support for sandbox SDL console input: Add Ctrl+Shift+Z support for redo cli: Add a Kconfig for enhanced editing cmd: editenv: Add -e flag for expo-based editing test: Add editenv test for init/poll/uninit functions expo: Convert BKEY_UP/DOWN to control characters for text input cli: Add Ctrl+Left/Right arrow support for word navigation expo: Add SCENEOF_MULTILINE flag for textedit cli: Make Ctrl+K clear to end of line in multiline mode cli: Add Ctrl+Y to yank killed text cli: Add multi-level undo/redo support arch/sandbox/dts/cros-ec-keyboard.dtsi | 4 + boot/Kconfig | 9 + boot/Makefile | 1 + boot/editenv.c | 193 +++++++++++++++++++ boot/expo.c | 6 +- boot/scene.c | 2 + boot/scene_txtin.c | 73 ++++++- cmd/Kconfig | 47 ++++- cmd/nvedit.c | 50 ++++- common/Makefile | 1 + common/cli_getch.c | 40 ++++ common/cli_readline.c | 239 +++++++++++++++++++++-- common/cli_undo.c | 251 ++++++++++++++++++++++++ doc/develop/expo.rst | 21 ++ doc/usage/cmdline.rst | 68 +++++++ drivers/input/input.c | 54 ++++++ include/cli.h | 230 +++++++++++++++++++++- include/expo.h | 66 +++++++ include/test/test.h | 5 + include/test/video.h | 12 ++ test/boot/Makefile | 1 + test/boot/editenv.c | 253 +++++++++++++++++++++++++ test/boot/expo.c | 63 +++++- test/dm/video.c | 139 +++++++++++++- test/test-main.c | 2 + tools/buildman/buildman.rst | 5 +- tools/buildman/cfgutil.py | 21 +- tools/buildman/cmdline.py | 2 + tools/buildman/control.py | 4 + tools/buildman/test.py | 110 +++++++++++ tools/buildman/test_cfgutil.py | 48 +++++ 31 files changed, 1954 insertions(+), 66 deletions(-) create mode 100644 boot/editenv.c create mode 100644 common/cli_undo.c create mode 100644 test/boot/editenv.c -- 2.43.0 base-commit: a7d65f7fcee089ed97b46765e574279cad40d75f branch: exph

[PATCH 00/16] expo: Add multiline editing support for textedit
by Simon Glass 22 Jan '26

22 Jan '26

From: Simon Glass <simon.glass(a)canonical.com> This series enhances the expo text-input handling, particularly for the textedit object which supports multi-line text. The vidconsole uses a single shared context for cursor state, which causes problems when text-input objects need their own cursor blinking. This series adds dedicated vidconsole contexts for text input, then removes the old entry save/restore mechanism which is no longer needed. For multiline editing , this series adds support for navigating between visual lines using Ctrl-P and Ctrl-N. The expo textedit uses text measurement to position the cursor at the correct pixel location within multi-line text, maintaining the horizontal position when moving between lines. The series also fixes some bugs in text-input handling and adds some tests for rendering and keypress-handling. Simon Glass (16): video: Update vidconsole_idle() to process all contexts expo: Add tin parameter to scene_txtin_close() test: expo: Use expo_enter_mode() in textline render test expo: Use a dedicated vidconsole-context for text input expo: Drop entry save/restore in textline rendering video: Remove vidconsole_entry_save/restore() test: video: Add tests for independent vidconsole contexts expo: Fix text-input close on BKEY_SELECT expo: Fix text-input buffer size for CLI editing test: expo: Add open/close testing to expo_render_textedit test: expo: Add keypress tests to expo_render_textedit cli: Add multiline support to CLI line editing video: Add len parameter to vidconsole_measure() expo: support cursor positioning for multiline textedits expo: Add visual line navigation for multi-line textedit test: expo: Add more keypress tests for textedit boot/scene.c | 7 +- boot/scene_internal.h | 13 +- boot/scene_txtin.c | 218 +++++++++++++++++++++++++----- common/cli_readline.c | 17 +++ drivers/video/console_normal.c | 32 ----- drivers/video/console_truetype.c | 43 +----- drivers/video/vidconsole-uclass.c | 50 ++----- include/cli.h | 9 +- include/expo.h | 4 +- include/video_console.h | 56 +------- test/boot/expo.c | 142 +++++++++++++++++++ test/dm/video.c | 109 +++++++++------ 12 files changed, 458 insertions(+), 242 deletions(-) -- 2.43.0 base-commit: ad61e1d21a99f0342d7b70a6b3e997fd36dacbff branch: expg

[PATCH 00/33] Reorganise ext4l compatibility stubs
by Simon Glass 21 Jan '26

21 Jan '26

From: Simon Glass <simon.glass(a)canonical.com> The ext4l filesystem uses a large compatibility header (ext4_uboot.h) containing stubs for Linux kernel interfaces. This series moves these stubs to their proper locations in include/linux/, making them available to other subsystems and improving code organisation. The series: - Fixes list_sort() callback signature to match Linux kernel - Moves struct definitions and stubs to appropriate linux/ headers - Adds missing stubs to existing headers (fs.h, blkdev.h, slab.h, etc.) - Creates new stub headers where needed (iomap.h, super_types.h) - Consolidates and sorts the remaining includes This reduces ext4_uboot.h from over 550 lines to around 270 lines. At this point, the work can be considered complete. Simon Glass (33): linux/sort.h: Fix qsort implicit declaration warning list: Add const qualifiers to list_sort callback signature ext4l: Remove redundant header-location comments from ext4_uboot.h ext4l: Move file_operations and inode_operations to linux/fs.h ext4l: Move struct inode and time accessors to linux/fs.h ext4l: Move sb_ functions and SB_ macros to super_types.h ext4l: Move seq_ functions to linux/seq_file.h ext4l: Move inode state accessors to linux/fs.h ext4l: Move generic VFS operations to linux/fs.h ext4l: Move block device operations to linux/blkdev.h ext4l: Move file_ functions to linux/fs.h ext4l: Move fsnotify_sb_error() to linux/fs.h ext4l: Move DEFINE_WAIT to linux/wait.h ext4l: Move filemap_fdatawait_range_keep_errors() to pagemap.h ext4l: Move various stubs to proper linux/ headers ext4l: Consolidate DX_HASH_* into EXT4_UBOOT_NO_EXT4_H block ext4l: Have hash.c include ext4.h directly ext4l: Move inode and filesystem helpers to linux/fs.h ext4l: Move time_is_before_jiffies() to linux/jiffies.h ext4l: Remove duplicate ext4_update_overhead() declaration ext4l: Move xattr helper stubs to linux/xattr.h ext4l: Remove duplicate __ext4_xattr_set_credits() declaration ext4l: Move iomap stubs to linux/iomap.h ext4l: Move setattr stubs to linux/fs.h ext4l: Move finish_open_simple() and ihold() to linux/fs.h ext4l: Move nd_terminate_link() to linux/namei.h ext4l: Move blk_holder_ops to linux/blkdev.h ext4l: Move more stubs to standard Linux headers ext4l: Move WHITEOUT and usercopy stubs to headers ext4l: Move O_SYNC, S_NOQUOTA and kfree_link to headers linux: Add PAGE_SHIFT and PAGE_MASK to linux/compat.h linux: Add DEFINE_RAW_FLEX to linux/overflow.h ext4l: Consolidate and sort includes in ext4_uboot.h .../mach-stm32mp/cmd_stm32prog/stm32prog.c | 9 +- fs/ext4l/ext4_uboot.h | 1476 ++--------------- fs/ext4l/hash.c | 4 +- fs/ext4l/stub.c | 5 + fs/ubifs/gc.c | 19 +- fs/ubifs/replay.c | 6 +- include/linux/blkdev.h | 42 + include/linux/compat.h | 7 + include/linux/dax.h | 23 +- include/linux/fs.h | 336 +++- include/linux/fs/super_types.h | 44 + include/linux/iomap.h | 4 + include/linux/jiffies.h | 3 + include/linux/ktime.h | 9 + include/linux/list_sort.h | 8 +- include/linux/mm_types.h | 3 + include/linux/namei.h | 11 + include/linux/overflow.h | 12 + include/linux/pagemap.h | 2 + include/linux/percpu.h | 1 + include/linux/prefetch.h | 4 +- include/linux/proc_fs.h | 1 + include/linux/rwsem.h | 2 + include/linux/sched/mm.h | 3 + include/linux/seq_file.h | 8 + include/linux/slab.h | 2 + include/linux/sort.h | 2 +- include/linux/wait.h | 3 + include/linux/xattr.h | 4 + lib/efi_loader/efi_memory.c | 7 +- lib/list_sort.c | 12 +- 31 files changed, 716 insertions(+), 1356 deletions(-) -- 2.43.0 base-commit: 8e85f501c225ced3880282e5e168541ed4db047f branch: extw

[PATCH 00/17] ext4l: Move compatibility stubs to standard Linux headers
by Simon Glass 20 Jan '26

20 Jan '26

From: Simon Glass <simon.glass(a)canonical.com> The ext4 Linux port (ext4l) includes many compatibility stubs in ext4_uboot.h. This makes it harder to maintain and compare against upstream Linux, since the stubs are all in one U-Boot-specific file rather than in their canonical header locations. This series moves these stubs to their proper locations in the Linux header hierarchy: - Cache alignment macros to linux/cache.h - Pointer macros to linux/slab.h - Compiler attributes to linux/compiler_attributes.h - Inode helpers and state bits to linux/fs.h - Memory and kunit stubs to standard headers - Little-endian bitops to asm-generic/bitops/le.h - UUID helpers to linux/statfs.h - Time functions to linux/time.h - Buffer operations to linux/buffer_head.h - Block device stubs to linux/blkdev.h - Folio operations to proper headers - Super operations to linux/fs/super_types.h - Lock and scheduler stubs to proper headers This makes the U-Boot Linux compatibility layer more closely mirror the actual Linux header structure, easing future synchronisation with upstream ext4 changes. Simon Glass (17): ext4l: Move cache alignment and pointer macros to headers ext4l: Move inode helpers to standard linux headers ext4l: Move inode state bits to linux/fs.h ext4l: Move memory and kunit stubs to standard headers ext4l: Create asm-generic/bitops/le.h for little-endian bitops ext4l: Move uuid_to_fsid to linux/statfs.h and use hexdump.h ext4l: Move time functions to linux/time.h ext4l: Move buffer and filesystem helpers to standard headers ext4l: Move block device atomic write stubs to linux/blkdev.h ext4l: Move get_block_t typedef to linux/fs.h ext4l: Move buffer operations to linux/buffer_head.h ext4l: Move inode stubs to proper headers ext4l: Move folio operations to proper headers ext4l: Move super_operations to linux/fs/super_types.h ext4l: Move lock and scheduler stubs to proper headers ext4l: Move lock bit operations to asm-generic/bitops/lock.h ext4l: Move superblock write stubs to linux/fs/super_types.h fs/ext4l/ext4_uboot.h | 325 +++++++--------------------- include/asm-generic/bitops/le.h | 76 +++++++ include/asm-generic/bitops/lock.h | 30 +++ include/kunit/static_stub.h | 12 +- include/linux/blkdev.h | 5 + include/linux/buffer_head.h | 74 +++++++ include/linux/cache.h | 22 ++ include/linux/compiler_attributes.h | 10 + include/linux/cred.h | 3 + include/linux/fs.h | 85 +++++++- include/linux/fs/super_types.h | 33 +++ include/linux/mutex.h | 1 + include/linux/pagemap.h | 18 ++ include/linux/pagevec.h | 11 + include/linux/sched.h | 1 + include/linux/sched/mm.h | 32 +++ include/linux/slab.h | 9 + include/linux/spinlock.h | 4 + include/linux/statfs.h | 19 ++ include/linux/time.h | 14 ++ include/linux/writeback.h | 8 + 21 files changed, 537 insertions(+), 255 deletions(-) create mode 100644 include/asm-generic/bitops/le.h create mode 100644 include/asm-generic/bitops/lock.h create mode 100644 include/linux/cache.h create mode 100644 include/linux/sched/mm.h -- 2.43.0 base-commit: f900786595b058fec921a56375bd3951fcae4553 branch: extv

[PATCH 00/36] video: Add multiple-context support to vidconsole (part F)
by Simon Glass 20 Jan '26

20 Jan '26

From: Simon Glass <simon.glass(a)canonical.com> At present expo textline objects are handled in a rather ad-hoc manner. When a textline is 'opened', the text is written out using vidconsole and the state is saved in the scene. When the user types a character, the state is restored, the character is written to the vidconsole, then the state is saved again. It is basically using the command-editor code. If the user press Ctrl-A, a suitable number of backspaces are written to move the cursor to the start. If the user then inserts a character, the entire string is written out (which is probably undesirable) and then backspaces are written again. Typing into a lineedit shows the same characters on the text console. This approach was designed for the text console and extended into the vidconsole. It was further extended into expo as it is fairly simple and saves code space. However it is not really suitable for a textedit, which may have many lines of text and needs to support moving up and down through these lines. Ideally we would separate expo a little from the CLI editor. As a start towards resolving these problems, this series adds support for multiple, independent vidconsole contexts. This enables expo text-input objects to each have their own cursor position, font settings and CLI line state, allowing multiple text fields to operate independently on the same display. This series: - Adds a context parameter to vidconsole functions throughout the stack - Moves CLI line state into text-input objects for expo - Maintains a list of contexts in the vidconsole uclass - Centralises context allocation and freeing in the uclass This is preparation for supporting multiple text-input fields in the expo menu system, where each field needs independent cursor tracking. Size growth is approximately 300 bytes on Thumb2, for boards which enable command-line editing and expo. This series also includes a fix for LUKS in CI. Simon Glass (36): test: Fix LUKS device-name collision in CI environments video: Pass context to vidconsole_set_cursor_pos() video: Pass context to vidconsole_entry_start() cli: Split initial-text output from cli_cread_init() video: Add per-device vidconsole_readline_start/end() video: Pass context to vidconsole_readline_start/end() expo: Move and generalise scene_textline_send_key() expo: Add CLI line state to text-input objects expo: Use text-input CLI line state instead of scene's video: Pass context to backspace() method video: Pass context to vidconsole_newline/back() video: Pass context to console_fixed_putc_xy() video: Pass context to vidconsole_putc_xy() video: Pass context to vidconsole_output_glyph() video: Pass context to vidconsole_escape_char() video: Pass context to get_cursor_info() method video: Pass context to vidconsole_show/hide_cursor() video: Pass context to vidconsole_put_char() video: Pass context to vidconsole_put_string() et al video: Pass context to mark_start() method video: Pass context to select_font() method video: Pass context to select_metrics() video: Pass context to console_alloc_cursor() video: Pass context to vidconsole_set_bitmap_font() video: Pass context to set_bitmap_font() video: Pass context to console_set_font() video: Pass context to get_font_size() expo: Pass context to draw_string() expo: Pass context to scene_txt_render() expo: Pass context to scene_obj_render() expo: Pass context to scene_render_obj() video: Maintain a list of contexts in vidconsole video: Allocate the cursor in the uclass video: Pass a cursor pointer to console_alloc_cursor() video: Move context freeing to uclass video: Move context allocation from drivers to uclass board/atmel/common/video_display.c | 2 +- board/kosagi/novena/novena.c | 2 +- boot/expo_test.c | 22 +-- boot/scene.c | 83 +++++---- boot/scene_internal.h | 13 +- boot/scene_textline.c | 47 ----- boot/scene_txtin.c | 80 ++++++-- cmd/font.c | 6 +- cmd/video.c | 6 +- common/cli_readline.c | 16 +- common/splash.c | 2 +- drivers/video/console_core.c | 46 +++-- drivers/video/console_normal.c | 47 +---- drivers/video/console_rotate.c | 24 +-- drivers/video/console_truetype.c | 80 ++++---- drivers/video/vidconsole-uclass.c | 276 ++++++++++++++++++---------- drivers/video/vidconsole_internal.h | 49 ++++- include/cli.h | 12 ++ include/expo.h | 2 + include/video_console.h | 120 ++++++++---- test/boot/expo.c | 12 +- test/cmd/font.c | 6 +- test/dm/video.c | 114 ++++++------ test/py/tests/fs_helper.py | 7 +- 24 files changed, 621 insertions(+), 453 deletions(-) -- 2.43.0 base-commit: 6ffc40c796bef9ab0f4785ad978aebbcd883eec2 branch: expf

[PATCH 00/16] ext4l: Move definitions to standard Linux headers
by Simon Glass 19 Jan '26

19 Jan '26

From: Simon Glass <simon.glass(a)canonical.com> This series continues the work of reducing fs/ext4l/ext4_uboot.h by moving definitions to their proper locations in include/linux/ headers. The ext4_uboot.h file provides Linux kernel compatibility for the ext4l filesystem driver. Many definitions were placed there temporarily during initial development. This series moves them to standard header locations matching the Linux kernel organisation: - Inode locking stubs and helpers to linux/fs.h - Compiler helpers (data_race, might_sleep) to linux/compiler.h and linux/kernel.h - Instruction pointer macros to linux/kernel.h - Credential types (user_namespace) to linux/cred.h - Filesystem types (fstrim_range) to linux/fs.h - Quota types (qsize_t) to linux/quotaops.h - String helpers (memweight) to linux/string.h - UID/GID helpers to new linux/highuid.h - Overflow helpers (struct_size) to new linux/overflow.h - Min/max helpers (umin) to linux/minmax.h - Slab helpers (KMEM_CACHE) to linux/slab.h - Rate limit helpers (WARN_RATELIMIT) to linux/ratelimit.h - Cycle counter (get_cycles) to new asm-generic/timex.h - Superblock definition (struct super_block) to new linux/fs/super_types.h This reduces ext4_uboot.h from 1666 to 1620 lines. Simon Glass (16): ext4l: Move inode locking stubs to linux/fs.h ext4l: Add linux/fs/super_types.h for struct super_block ext4l: Move inode and superblock helpers to linux/fs.h ext4l: Move data_race, might_sleep, fallthrough to standard headers ext4l: Move _RET_IP_, _THIS_IP_, BITS_PER_BYTE to standard headers ext4l: Move user_namespace to linux/cred.h ext4l: Move fstrim_range to linux/fs.h ext4l: Move qsize_t to linux/quotaops.h ext4l: Move memweight to linux/string.h ext4l: Add linux/highuid.h and move UID/GID helpers ext4l: Add linux/overflow.h and move struct_size ext4l: Move umin to linux/minmax.h ext4l: Move KMEM_CACHE macro to linux/slab.h ext4l: Use existing linux/nospec.h for array_index_nospec ext4l: Move WARN_RATELIMIT to linux/ratelimit.h ext4l: Add asm-generic/timex.h and move get_cycles fs/ext4l/ext4_uboot.h | 148 +++++++-------------------------- include/asm-generic/timex.h | 21 +++++ include/linux/compiler.h | 8 ++ include/linux/cred.h | 9 ++ include/linux/fs.h | 51 +++++++++++- include/linux/fs/super_types.h | 68 +++++++++++++++ include/linux/highuid.h | 19 +++++ include/linux/kernel.h | 17 ++++ include/linux/minmax.h | 18 ++++ include/linux/overflow.h | 23 +++++ include/linux/quotaops.h | 3 + include/linux/ratelimit.h | 9 ++ include/linux/slab.h | 10 +++ include/linux/string.h | 24 ++++++ 14 files changed, 308 insertions(+), 120 deletions(-) create mode 100644 include/asm-generic/timex.h create mode 100644 include/linux/fs/super_types.h create mode 100644 include/linux/highuid.h create mode 100644 include/linux/overflow.h -- 2.43.0 base-commit: 0a7a5e4a3d20d76f21de32292f847e05628b8a67 branch: extu

[PATCH 00/23] Reduce ext4_uboot.h by moving definitions to linux headers
by Simon Glass 19 Jan '26

19 Jan '26

From: Simon Glass <simon.glass(a)canonical.com> This series continues the work to reduce fs/ext4l/ext4_uboot.h by moving definitions to their proper locations in include/linux/ The ext4l compatibility header started at 2584 lines. Previous work reduced it to 1816 lines. This series further reduces it to 1677 lines by moving various definitions to appropriate headers: - Block I/O flags (REQ_OP_*, REQ_SYNC, etc.) to linux/blk_types.h - Block device flags (BLK_OPEN_*) to linux/blkdev.h - Memory allocation flags (__GFP_*, SLAB_*) to linux/slab.h - Scheduler stubs to linux/sched.h - Process flags (PF_MEMALLOC*) to linux/sched.h - System state definitions to linux/kernel.h - Quota format constants to linux/quotaops.h - STATX flags and struct kstat to linux/stat.h - Timer definitions to new linux/hrtimer.h - Inode mutex classes to linux/fs.h - Various other small moves This improves code organisation by placing definitions in headers matching Linux kernel structure, making the codebase easier to maintain and understand.

[PATCH 00/16] expo: Continue preparations for textedit (part D)
by Simon Glass 18 Jan '26

18 Jan '26

From: Simon Glass <simon.glass(a)canonical.com> At present vidconsole uses a save/restore model for its state. The textline object saves the state, does its drawing, then restores it. This is fairly clumsy and makes textedit harder to implement. This series continues the changes to adjust this, adding a putch() callback to the CLI line-editing code, so that output can (later) be directed to the correct context. It also adds word-wrapping support to the textedit scene object. The remaining patches refactor the textline and textedit code to share common functionality through a new scene_txtin structure and helper functions. This allows textedit to properly calculate its bounding box and dimensions, enabling word-wrapping within the edit area. It also includes an attempted fix for the flaky FPDT test. Overall code-size is neutral, e.g. for Thumb2 with EXPO: 03: cli: Add putch callback to struct cli_line_state arm: (for 1/1 boards) all +92.0 text +92.0 04: cli: Convert ERASE_TO_EOL macro to a function arm: (for 1/1 boards) all -104.0 text -104.0 05: cli: Add cls_putnstr() for string output with callback arm: (for 1/1 boards) all -20.0 text -20.0 Without EXPO, code size reduces by about 56 bytes (e.g. xilinx_versal_virt) Simon Glass (16): test: acpi: Fix flaky dm_test_acpi_fpdt checksum test cli: Add putch callback to struct cli_line_state cli: Convert ERASE_TO_EOL macro to a function cli: Add cls_putnstr() for string output with callback expo: Wire up putch callback for textline editing test: expo: Add a separate test for textedit expo: Refactor textedit to use label_id and edit_id expo: Rename textline max_chars to line_chars expo: Add line_chars to scene_obj_txtedit expo: Add arrangement support for textedit expo: Introduce scene_txtin for common text-input fields expo: Factor out common calc_bbox code into scene_txtin.c expo: Add scene_obj_txtin() helper for text-input objects expo: Add scene_txtin_init() for common text-input init expo: Add scene_txtin_arrange() for common arrangement code expo: Enable textedit dimension calculation for word-wrap boot/Kconfig | 1 + boot/Makefile | 2 +- boot/bootctl/multi_ui.c | 4 +- boot/bootflow_menu.c | 6 +- boot/cedit.c | 12 ++-- boot/expo_build.c | 12 ++-- boot/expo_dump.c | 10 ++- boot/scene.c | 64 ++++++++++--------- boot/scene_internal.h | 78 ++++++++++++++++++++--- boot/scene_textedit.c | 65 +++++++++++++++---- boot/scene_textline.c | 105 ++++++++++++++----------------- boot/scene_txtin.c | 70 +++++++++++++++++++++ cmd/Kconfig | 8 +++ common/cli_readline.c | 121 ++++++++++++++++++++++-------------- doc/usage/cmd/cedit.rst | 2 +- include/cli.h | 2 + include/expo.h | 45 ++++++++------ test/boot/bootctl/bootctl.c | 12 ++-- test/boot/cedit.c | 8 +-- test/boot/expo.c | 105 ++++++++++++++++++++----------- test/dm/acpi.c | 13 ++-- 21 files changed, 495 insertions(+), 250 deletions(-) create mode 100644 boot/scene_txtin.c -- 2.43.0 base-commit: 3e4570227c362cc009a7f308c824c50da750bf1c branch: expd

[PATCH 00/12] ext4l: Continue reducing ext4_uboot.h size with more headers
by Simon Glass 18 Jan '26

18 Jan '26

From: Simon Glass <simon.glass(a)canonical.com> This series continues reducing fs/ext4l/ext4_uboot.h by moving more definitions to appropriate include/linux/ header files. The previous series reduced the file from 2584 to 1980 lines. This series further reduces it to 1816 lines (total 30% reduction). New headers created: - fiemap.h: FIEMAP extent types and fiemap_extent_info structure - statfs.h: kstatfs structure for filesystem statistics - exportfs.h: NFS export operations (fid, export_operations) - mbcache.h: Metadata block cache stubs - wait_bit.h: Wait bit operation stubs - ratelimit.h: Rate limiting stubs - projid.h: Project ID type (kprojid_t) - mnt_idmap.h: Mount ID mapping stub - hash.h: hash_64() and hash_32() functions - blockgroup_lock.h: Block group lock structure - delayed_call.h: Delayed function call support Updated headers: - capability.h: Added CAP_SYS_ADMIN - uio.h: Added kiocb and IOCB_* flags - utsname.h: Added init_utsname() function - proc_fs.h: Added proc_ops structure and procfs stubs All implementations are appropriate stubs for U-Boot's single-threaded environment. Tests pass with these changes. Simon Glass (12): linux: capability: Add CAP_SYS_ADMIN constant linux: uio: Add kiocb struct and IOCB_* flags linux: Add fiemap.h header with extent mapping types linux: Add statfs.h header with kstatfs struct linux: Add exportfs.h header with NFS export operations linux: Add mbcache.h header with metadata cache stubs linux: Add wait_bit.h header with wait bit stubs linux: Add ratelimit.h header with rate limiting stubs linux: utsname/proc_fs: Add init_utsname() and proc_ops linux: Add projid.h and mnt_idmapping.h headers linux: Add hash.h header with hash_64 function linux: Add blockgroup_lock.h and delayed_call.h headers fs/ext4l/ext4_uboot.h | 250 ++++++-------------------------- include/linux/blockgroup_lock.h | 25 ++++ include/linux/capability.h | 1 + include/linux/delayed_call.h | 56 +++++++ include/linux/exportfs.h | 78 ++++++++++ include/linux/fiemap.h | 45 ++++++ include/linux/hash.h | 33 +++++ include/linux/mbcache.h | 60 ++++++++ include/linux/mnt_idmapping.h | 23 +++ include/linux/proc_fs.h | 25 ++++ include/linux/projid.h | 43 ++++++ include/linux/ratelimit.h | 35 +++++ include/linux/statfs.h | 42 ++++++ include/linux/uio.h | 19 +++ include/linux/utsname.h | 12 ++ include/linux/wait_bit.h | 47 ++++++ 16 files changed, 587 insertions(+), 207 deletions(-) create mode 100644 include/linux/blockgroup_lock.h create mode 100644 include/linux/delayed_call.h create mode 100644 include/linux/exportfs.h create mode 100644 include/linux/fiemap.h create mode 100644 include/linux/hash.h create mode 100644 include/linux/mbcache.h create mode 100644 include/linux/mnt_idmapping.h create mode 100644 include/linux/projid.h create mode 100644 include/linux/ratelimit.h create mode 100644 include/linux/statfs.h create mode 100644 include/linux/wait_bit.h -- 2.43.0 base-commit: 3e4570227c362cc009a7f308c824c50da750bf1c branch: exts
