[PATCH 00/15] boot: Support priority for global bootmeths
by Simon Glass 30 Sep '25

30 Sep '25

From: Simon Glass <sjg(a)chromium.org> At present global bootmeths always run first, before all other bootmeths. Optimisations in the code take advantage of this, putting them at the end, so they can be used once and then forgotten. In some cases it is useful to run global bootmeths later in the boot. For example, the EFI-bootmgr bootmeth may itself scan devices and the network, so running it first can hold up the boot significantly for boards not actually relying on EFI-bootmgr to boot. This series introduces a new field in global bootmeths which indicates the priority, using the same scheme as is used with bootdev hunters. Thus it is possible to insert the EFI-bootmgr bootmeth just before the hunter for network bootdevs is invoked. Despite the simplicity of the concept and the relatively small series, this is a fairly significant enhancement. It is also quite tricky to implement, largely due to the way the original code was written, with global bootmeths being a small, size-optimised add-on to the original bootstd implementation. For now we only allow each global bootmeth to run at most once, but this implementation is written in a way that we could relax that if needed. Then the bootmeth itself could decide whether to run at any particular point in the bootflow iteration. Size growth is about 390 bytes on Thumb2 (e.g. firefly-rk3288) if CONFIG_BOOTMETH_GLOBAL is enabled, which it normally is. With that disabled (which saves about 4K on the same platform), there is no growth. Simon Glass (15): boot: Improve comments related to global bootmeths boot: Add more debugging to iter_incr() boot: Move showing of bootflows out of the command boot: Add a new test for global bootmeths boot: Update first_glob_method when dropping a bootmeth boot: Add a flag for whether there are global bootmeths boot: Keep track of which bootmeths have been used boot: Move preparing bootdev into a function boot: Support rescanning the global bootmeths boot: Only run global bootmeths once each boot: Implement a priority for global bootmeths boot: Don't change the method count after global bootmeths boot: Run global bootmeths after all bootdevs are exhausted boot: Run the EFI bootmgr just before network devices boot: doc: Update for new global-bootmeth features boot/bootflow.c | 275 +++++++++++++++++++++++++++++-- boot/bootmeth-uclass.c | 15 +- boot/bootmeth_efi_mgr.c | 1 + cmd/bootflow.c | 68 +------- doc/develop/bootstd/overview.rst | 26 ++- include/bootflow.h | 29 +++- include/bootmeth.h | 4 + test/boot/bootflow.c | 73 +++++++- 8 files changed, 397 insertions(+), 94 deletions(-) -- 2.43.0 base-commit: 2617d1179c27ba51e9eb7996b7062a0205c587a9 branch: glob

[PATCH 1/2] WIP: Revert "efi: arm: Simplify the crt0 file and update link script"
by Simon Glass 26 Sep '25

26 Sep '25

From: Simon Glass <sjg(a)chromium.org> Unfortunately the arm64 toolchain does not correctly add a header when buiding the payload. Restore the manual header for now. This change cannot be applied since it will break the app, but it should allow for experimentation. This reverts commit 7fa6a68131d154c5ab1ee79c5a50fdb10fdd63a6.

[PATCH 00/22] efi: Tidy up some commands and provide a keyboard driver
by Simon Glass 25 Sep '25

25 Sep '25

From: Simon Glass <sjg(a)chromium.org> This series collect various odds and ends to make the ARM EFI app show a menu that looks reasonable, including truetype fonts and a new keyboard driver, selectable by setting stdin to 'efi-kbd'. Some highlights: - fix some bugs in addr_find and part_find and adds docs / tests - reset pager when clearing the console - use at least 1G of memory with EFI since the app allocates 512M - allow NEON registers so floating point can work (truetype) - show the global_data flags with bdinfo Simon Glass (22): bdinfo: Show the flags script: Use a minimum of 1G of memory for EFI console: Reset the pager when clearing the console doc: Fix up the booti examples efi: Avoid a memory leak in efi_bind_block() on error path efi: Drop config.h test: Drop an unwanted blank line in dm_test_video_box() test: Allow creating disks with a different Ubuntu version cmd: part_find: Correct radix and calls cmd: sandbox: efi: Enable part_find for sandbox and EFI app cmd: Refactor part_find() into separate functions doc: test: Add docs and test for part_find cmd: Update addr_find to use a simple lmb allocation cmd: Update addr_find to ignore the devicetree doc: test: Add docs and test for addr_find boot: Tidy up positioning in bootflow_menu_new() expo: Allow manual positioning of menu items Revert "ARM: Prevent the compiler from using NEON registers" efi: Enable truetype in the ARM app efi: arm: Drop setting of fdt_addr efi: Move key decoding into a shared file efi: app: Provide a keyboard driver arch/arm/config.mk | 1 - arch/arm/dts/efi-arm_app.dts | 4 + board/efi/efi-arm_app/efi-arm_app.env | 1 - boot/bootflow_menu.c | 8 +- boot/scene.c | 14 +++ cmd/Kconfig | 5 +- cmd/addr_find.c | 23 ++-- cmd/bdinfo.c | 1 + cmd/part_find.c | 154 ++++++++++++++--------- common/console.c | 1 + configs/efi-arm_app64_defconfig | 1 + doc/usage/cmd/addr_find.rst | 63 ++++++++++ doc/usage/cmd/booti.rst | 4 +- doc/usage/cmd/part_find.rst | 119 ++++++++++++++++++ doc/usage/index.rst | 2 + drivers/input/Kconfig | 14 +++ drivers/input/Makefile | 2 + drivers/input/efi_keyb.c | 173 ++++++++++++++++++++++++++ drivers/net/efi_net.c | 1 - drivers/serial/serial_efi.c | 15 +-- drivers/tpm/tpm2_efi.c | 1 - include/efi.h | 32 +++++ include/expo.h | 27 +++- lib/efi/Makefile | 1 + lib/efi/input.c | 40 ++++++ lib/efi_client/efi_app_init.c | 4 +- scripts/build-efi | 2 +- test/cmd/Makefile | 2 + test/cmd/addr_find.c | 27 ++++ test/cmd/bdinfo.c | 1 + test/cmd/part_find.c | 42 +++++++ test/dm/video.c | 1 - test/py/img/ubuntu.py | 8 +- 33 files changed, 683 insertions(+), 111 deletions(-) create mode 100644 doc/usage/cmd/addr_find.rst create mode 100644 doc/usage/cmd/part_find.rst create mode 100644 drivers/input/efi_keyb.c create mode 100644 lib/efi/input.c create mode 100644 test/cmd/addr_find.c create mode 100644 test/cmd/part_find.c -- 2.43.0 base-commit: 271239736374b0ed1e90311ac07f2346ff858414 branch: api

[PATCH 00/24] boot: efi: Various improvements to booting with the EFI app
by Simon Glass 22 Sep '25

22 Sep '25

From: Simon Glass <sjg(a)chromium.org> This series provides a number of tweaks which make it easier to test booting with the EFI app, particularly on ARM: - 'fake go' in bootstd - more debugging in various places - tidy up the generally incorrect ATAGs error - drop a panic() in the bowels of boot - ensure booti does not overwrite memory when relocating It also includes a way to quit or disable the pager, which is very helpful when running the app on a machine with no serial console. Finally, a bug in the release script is causing CI to fail, so a few patches deal with that. Simon Glass (24): doc: Resolve a formatting error in upcoming releases scripts: Fix RST formatting in release_version.py console: Restore old pager test-bypass value console: Correct condition for setting enabled pager bypass console: Add bypass keypress to disable paging console: Add a way to quit pager with no further output boot: Provide a Kconfig to enable faking the boot boot: Select the fake-go state explicitly boot: Tidy up the bootflow flags boot: Provide a bootflow option to fake a boot boot: Drop hex prefix from the booti image-moving message boot: Show the ramdisk node when debugging boot: Support a fake go with pxe boot: Add more debugging around devicetree selection boot: Fix code formatting in fit_image_load() boot: Add more debugging in FIT-handling arm: Update boot_prep_linux() to return an error arm: bootm: Fix a confusing message about ATAGs lmb: Provide a static inline for lmb_alloc() arm: Use lmb when relocating the image efi: Include efi.h in the efi_variable.h header efi: app: Call efi_exit() if board_init_r() returns efi: app: Move efi_main() to the bottom of the file efi: app: arm: Add various options to the build arch/arm/lib/bootm.c | 22 +++- arch/arm/lib/image.c | 15 ++- boot/Kconfig | 8 ++ boot/bootm.c | 16 ++- boot/ext_pxe_common.c | 4 + boot/image-board.c | 7 +- boot/image-fdt.c | 3 + boot/image-fit.c | 12 +- boot/pxe_utils.c | 21 +++- cmd/bootflow.c | 16 ++- cmd/booti.c | 2 +- common/cli_readline.c | 1 + common/console.c | 2 +- common/pager.c | 56 +++++++-- configs/efi-arm_app64_defconfig | 5 + doc/develop/concept_releases.rst | 3 +- doc/usage/cmd/bootflow.rst | 3 + doc/usage/cmd/bootm.rst | 3 +- doc/usage/console.rst | 6 +- include/bootflow.h | 14 ++- include/efi_variable.h | 1 + include/image.h | 3 +- include/lmb.h | 9 ++ include/pager.h | 22 ++++ include/pxe_utils.h | 2 + lib/efi_client/efi_app.c | 113 +++++++++--------- scripts/release_version.py | 3 +- test/common/pager.c | 93 ++++++++++++++- test/scripts/test_release_version.py | 164 +++++++++++++++++++++++++++ test/test-main.c | 6 +- 30 files changed, 519 insertions(+), 116 deletions(-) -- 2.43.0 base-commit: 05cebf0bdd955fa267b1533bbf145499f0af63b9 branch: loadw

[PATCH 00/42] video: Support a cursor more generally
by Simon Glass 19 Sep '25

19 Sep '25

From: Simon Glass <sjg(a)chromium.org> At present U-Boot does not support displaying a cursor on the console, except with expo. It is quite useful to have a cursor, particularly when using the command-line editor. This series adds tracking of the cursor position for both truetype and normal consoles. The cursor is shown when U-Boot is idle and is removed before writing characters to the display. A save-buffer ensures that the old display contents are provided. Some related improvements in this series include: - expo lineedit support with normal console - arrow keys now render correctly when editing commands with truetype - truetype console now also supports bitmap fonts The cursor is not currently supported for rotated consoles. A README for claude is provided, although so far I have not had too much success with it. A fix for an intermittent build is added as well, along with silencing some build messages noticed from Rust ulib. Simon Glass (42): Provide a README for Claude cyclic: Avoid showing messages when debugging video: Correct ops check for nominal, entry save/restore Makefile: Silence the example Rust build scripts: Fix conditional syntax for capsule ESL generation test: video: Split long strings video: Provide an option to enable the cursor snow: link: Disable the cursor video: console: Put fixed-font rendering into a shared file video: truetype: Rename the FONT_ENTRY() macro video: Move setting of the bitmap font into uclass video: Allow selection of bitmap fonts in truetype video: truetype: Handle rendering of bitmap fonts video: truetype: Use common cursor-drawing code video: Correct cursor handling when the the left side video: Convert to use uclass_id_foreach_dev() video: Provide an idle function for the console video: Provide state for the cursor video: Rename draw_cursor_vertically() to cursor_show() video: Update cursor_show() to take a simple pointer video: Move cursor drawing into the uclass video: Track the current CLI index video: Provide a way to indicate the start of CLI entry console: Add debugging for kerning video: truetype: Record the position where CLI entry starts video: truetype: Track characters and their widths expo: Enable the cursor when editing a textline video: Track whether the cursor is enabled video: Drop vidconsole_set_cursor_visible() video: Update normal console to use tracking information video: Add save and restore drivers for normal console video: Drop extra parameters from get_cursor_info() video: Support a cursor in multi-line text video: Drop extra parameters from vidconsole_show_cursor() video: Provide a buffer to hold pixels behind the cursor video: Support reading the framebuffer when writing video: Save overwritten pixels when drawing the cursor video: Show the cursor when idle video: truetype: Clear after the current char on insert video: truetype: Avoid clearing on backspace video: Add some notes about the cursor console: Add some cursor tests .claude/.gitignore | 1 + .claude/README.md | 69 ++++++ .gitignore | 1 + boot/scene_textline.c | 9 +- cmd/font.c | 3 - common/Kconfig | 9 + common/cli_readline.c | 5 + common/cyclic.c | 5 +- configs/chromebook_link_defconfig | 1 + configs/snow_defconfig | 1 + doc/usage/cmd/font.rst | 16 +- drivers/video/Kconfig | 8 + drivers/video/console_core.c | 195 ++++++++++++++--- drivers/video/console_normal.c | 140 ++++++++---- drivers/video/console_truetype.c | 326 ++++++++++++++++++---------- drivers/video/vidconsole-uclass.c | 176 ++++++++++++++- drivers/video/vidconsole_internal.h | 77 ++++++- drivers/video/video-uclass.c | 30 ++- examples/rust/Makefile | 3 - include/video_console.h | 164 ++++++++++++-- scripts/Makefile.lib | 5 +- test/cmd/font.c | 15 +- test/dm/video.c | 162 +++++++++++++- 23 files changed, 1173 insertions(+), 248 deletions(-) create mode 100644 .claude/.gitignore create mode 100644 .claude/README.md -- 2.43.0 base-commit: 0c2531998ee8fc2da099cb3e20cbabc5221c0b3d branch: curs

15 Sep '25

From: Simon Glass <sjg(a)chromium.org> Add a virtio input device driver that supports tablets and mice using the existing mouse uclass. The driver handles absolute and relative coordinates. Mouse buttons are supported (left, right, middle). EV_SYN events are skipped.

[PATCH 00/17] mouse: Provide some support for using a mouse
by Simon Glass 15 Sep '25

15 Sep '25

From: Simon Glass <sjg(a)chromium.org> This series resurects some old code that was never submitted, related to using Nuklear with U-Boot. It includes: - a very simple mouse uclass - sandbox mouse driver - USB mouse driver, useful on x86 - EFI mouse driver, useful when running as an EFI app - script updates to use the above with build-qemu and build-efi It also includes a few small patches for sandbox, tests and membuf Not everything is fully working at present: - Mouse works on x86 QEMU (after 'usb start') but not ARM - Mouse works on real hardware with EFI, but not with build-efi script - Mouse times out with 'usb start', even though it does actually work More work will be needed to tidy up these remaining issues. Simon Glass (17): membuf: Add a function to set up a static membuf sandbox: Add a way to set the window title test: Add newlines at the end of the img functions input: Add mouse support sandbox: sdl: Add support for mouse input input: sandbox: Provide a mouse driver input: Add a command to show mouse input sandbox: Enable the mouse sandbox: Provide a test for the mouse uclass usb: Add a USB mouse driver mouse: Provide a way to read clicks efi: Add the simple-pointer protocol efi: Provide a mouse driver for EFI efi: arm: x86: Enable the mouse script: Support mouse with build-efi/qemu scripts x86: emulation: Enable USB support qemu: Enable the mouse MAINTAINERS | 7 + arch/arm/dts/efi-arm_app.dts | 5 + arch/sandbox/cpu/sdl.c | 46 +++- arch/sandbox/cpu/start.c | 9 + arch/sandbox/dts/sandbox.dtsi | 4 + arch/sandbox/dts/test.dts | 4 + arch/sandbox/include/asm/sdl.h | 9 + arch/sandbox/include/asm/state.h | 2 + arch/sandbox/include/asm/test.h | 17 ++ arch/x86/dts/efi-x86_app.dts | 4 + cmd/Kconfig | 9 + cmd/Makefile | 1 + cmd/mouse.c | 69 ++++++ configs/qemu-x86_64_defconfig | 3 + configs/qemu-x86_defconfig | 3 + configs/tools-only_defconfig | 2 +- drivers/input/Kconfig | 29 +++ drivers/input/Makefile | 7 + drivers/input/efi_mouse.c | 221 +++++++++++++++++++ drivers/input/mouse-uclass.c | 72 +++++++ drivers/input/sandbox_mouse.c | 84 ++++++++ drivers/input/usb_mouse.c | 353 +++++++++++++++++++++++++++++++ include/dm/uclass-id.h | 1 + include/efi.h | 1 + include/efi_api.h | 29 +++ include/membuf.h | 17 +- include/mouse.h | 105 +++++++++ include/usb.h | 1 + lib/efi/device_path.c | 1 + lib/membuf.c | 8 + scripts/build-efi | 3 + scripts/build-qemu | 6 +- test/dm/Makefile | 1 + test/dm/mouse.c | 217 +++++++++++++++++++ test/lib/membuf.c | 19 ++ test/py/img/android.py | 2 +- test/py/img/armbian.py | 2 +- test/py/img/cedit.py | 2 +- test/py/img/chromeos.py | 2 +- test/py/img/common.py | 2 +- test/py/img/efi.py | 2 +- test/py/img/fedora.py | 2 +- test/py/img/localboot.py | 2 +- test/py/img/ubuntu.py | 2 +- 44 files changed, 1374 insertions(+), 13 deletions(-) create mode 100644 cmd/mouse.c create mode 100644 drivers/input/efi_mouse.c create mode 100644 drivers/input/mouse-uclass.c create mode 100644 drivers/input/sandbox_mouse.c create mode 100644 drivers/input/usb_mouse.c create mode 100644 include/mouse.h create mode 100644 test/dm/mouse.c -- 2.43.0 base-commit: f3005834f6822612feb627cf52338e123c723e2b branch: ape

[PATCH 00/23] expo: Support interactions with a mouse or touchpad
by Simon Glass 15 Sep '25

15 Sep '25

From: Simon Glass <sjg(a)chromium.org> So far expo only supports user interaction with a keyboard. This is the common case, but for PC devices it is typical to have a mouse or touchpad available as well. Particularly for the configuration editor, these devices are often more convenient for selecting options than moving up and down with with the keyboard. This series adds mouse support to expo, providing a function to process a click similar to processing of a keypress. The core of this is a new expo_send_click() function. Within scenes, the logic to search for objects by and x and y position is provided. As with keypresses, expo provides clear separation between the processing of a click (which may or may not produce an action) and the handling of that action. This allows expo to be used within an existing event loop. Expo uses a mouse by default if available. This series also includes a few other minor improvements, including some code tidy-ups and support for filled boxes. Simon Glass (23): video: Provide a few Ubuntu fonts video: Support drawing filled boxes expo: Guard against a crash in scene_textline_calc_dims() expo: Support boxes fully test: video: Provide an easy way to watch video tests expo: Tidy up a few key-related comments expo: Add comments for enum bootmenu_id_t expo: Provide a way to enable the mouse expo: Tidy up image position with the menu expo: test: Move expo creation into a separate function expo: Provide a way to check if a position is within a menu expo: Allow checking if a position is within a textline expo: Tidy up comments for enum expoact_type expo: Add three new actions for mouse events expo: Support sending a click to a menu expo: Support sending a click to a scene expo: Support sending a click to an expo expo: Refactor expo_poll() to separate out key handling expo: Check the mouse when polling expo: Enable the mouse when available expo: Add a test helper for clicking on objects expo: Provide a test of cedit mouse behaviour expo: Provide a test of expo mouse behaviour arch/sandbox/dts/cedit.dtsi | 13 ++ boot/bootflow_internal.h | 14 +- boot/bootflow_menu.c | 4 +- boot/cedit.c | 23 +++ boot/expo.c | 85 ++++++++- boot/expo_build.c | 30 ++++ boot/scene.c | 248 ++++++++++++++++++++++++++- boot/scene_internal.h | 80 ++++++++- boot/scene_menu.c | 77 ++++++++- boot/scene_textline.c | 13 +- doc/develop/expo.rst | 16 ++ drivers/video/console_truetype.c | 8 + drivers/video/fonts/Kconfig | 32 +++- drivers/video/fonts/Makefile | 2 + drivers/video/fonts/ubuntu_bold.ttf | Bin 0 -> 270164 bytes drivers/video/fonts/ubuntu_light.ttf | Bin 0 -> 362552 bytes drivers/video/video-uclass.c | 27 +-- include/expo.h | 60 ++++++- include/test/cedit-test.h | 5 +- include/video.h | 3 +- test/boot/Makefile | 4 +- test/boot/cedit.c | 108 +++++++++++- test/boot/expo.c | 240 ++++++++++++++++++++++++-- test/boot/expo_common.c | 24 +++ test/boot/expo_common.h | 33 ++++ test/dm/video.c | 22 ++- 26 files changed, 1109 insertions(+), 62 deletions(-) create mode 100644 drivers/video/fonts/ubuntu_bold.ttf create mode 100644 drivers/video/fonts/ubuntu_light.ttf create mode 100644 test/boot/expo_common.c create mode 100644 test/boot/expo_common.h -- 2.43.0 base-commit: adb7fe6f5bb8f837020ac8de96646f19fbc65eaf branch: apf
