[PATCH 00/18] expo: Extend the boot menu
by Simon Glass 10 Oct '25

10 Oct '25

From: Simon Glass <sjg(a)chromium.org> The current boot menu works but it is still fairly basic. This series makes various improvements: - adds buttons for settings, help - adds a way to show other items for each OS (e.g. distro version-name) - adds a second logo - allows a box to be drawn around each item This series also provides a way to dump the expo as a text file, so that it can be examined or compared with another one. This is useful for debugging. A 'cedit dump' command allows dumping the information. A few fixes are included as well: - for mouse operation, avoid dropping click events - for keyboard, fix support for escape sequences Simon Glass (18): test: video: Fix 16bpp BMP pixel format conversion test: Add a way to printf() into a membuf input: Correct handling of mouse clicks expo: Correct key-polling timeout expo: Provide user-friendly output of scene enums expo: Provide a way to dump an expo expo: Provide a command to dump a cedit expo expo: Provide a version of scene_within() with takes an obj expo: Export scene_find_obj_within() and add a test expo: Allow searching click positions from top to bottom expo: Allow searching for any object type by position expo: Support clicking on any type of object expo: Add another logo in the bootmenu expo: Add a way to select settings expo: Add a help button expo: Add a way to display the distro version-name expo: Add a box around each item expo: Add an image that indicates verification MAINTAINERS | 3 + boot/Kconfig | 9 ++ boot/Makefile | 1 + boot/bootflow_internal.h | 24 +++- boot/bootflow_menu.c | 3 + boot/cedit.c | 4 + boot/expo.c | 8 +- boot/expo_dump.c | 271 +++++++++++++++++++++++++++++++++++ boot/scene.c | 131 +++++++++++++---- boot/scene_internal.h | 30 ++++ boot/scene_menu.c | 3 + cmd/Kconfig | 9 ++ cmd/cedit.c | 38 +++++ doc/usage/cmd/cedit.rst | 141 ++++++++++++++++++ drivers/input/mouse-uclass.c | 7 +- include/bootflow.h | 3 +- include/expo.h | 22 +++ include/membuf.h | 13 ++ lib/membuf.c | 14 ++ test/boot/expo.c | 192 +++++++++++++++++++++++-- test/dm/video.c | 21 ++- test/lib/membuf.c | 40 ++++++ 22 files changed, 932 insertions(+), 55 deletions(-) create mode 100644 boot/expo_dump.c -- 2.43.0 base-commit: cfffa4bf16338ed559487fc52a07296e6e475e20 branch: prog

[PATCH 00/14] expo: More mouse development for expo
by Simon Glass 06 Oct '25

06 Oct '25

From: Simon Glass <sjg(a)chromium.org> This series adds support for hiding the system pointer, if one is available, since it is confusing to have an expo pointer separate from the system one. It als introduces a simple test mode for expo, to check the frame rate, etc. Some minor tweaks in the video uclass are also included, as well as improvements to the video documentation. Simon Glass (14): video: Do the sync timing within video_sync() video: Add a little more documentation to the uclass mouse: Add comment for mouse_get_event() mouse: Add method to show/hide the system pointer mouse: Add support for scaling of video-device coordinates sandbox: mouse: Implement set_ptr_visible() sandbox: mouse: Add test for pointer visibility expo: Hide system pointer when entering expo mode expo: Introduce a test mode expo: Track the number of render calls expo: Add test mode to display frame count expo: Add FPS tracking to test mode expo: Expand timing to include render and poll expo: Use manual-sync mode arch/sandbox/cpu/sdl.c | 5 + arch/sandbox/include/asm/sdl.h | 11 ++ arch/sandbox/include/asm/test.h | 8 ++ boot/Kconfig | 10 ++ boot/Makefile | 1 + boot/expo.c | 44 ++++++- boot/expo_test.c | 217 ++++++++++++++++++++++++++++++++ doc/develop/expo.rst | 36 ++++++ drivers/input/mouse-uclass.c | 27 ++++ drivers/input/sandbox_mouse.c | 33 +++++ drivers/video/video-uclass.c | 44 +++++-- include/expo.h | 4 + include/expo_test.h | 181 ++++++++++++++++++++++++++ include/mouse.h | 66 ++++++++++ test/boot/expo.c | 123 ++++++++++++++++++ test/dm/mouse.c | 22 ++++ 16 files changed, 818 insertions(+), 14 deletions(-) create mode 100644 boot/expo_test.c create mode 100644 include/expo_test.h -- 2.43.0 base-commit: a302031398392259aebbcd3103e03a57b478c0a4 branch: proe

by Simon Glass 06 Oct '25

06 Oct '25

From: Simon Glass <sjg(a)chromium.org> This series integrates mouse support into expo and starts to build the infrastructure for drawing the mouse pointer more efficiently (i.e. without re-rendering the entire scene). It also adds a few more structs to video_defs.h for position and size. This is part D. Simon Glass (14): video: Add struct vid_pos for coordinates mouse: Use struct vid_pos for click position mouse: Update mouse_get_click() to use struct vid_pos expo: Update poll_mouse() to use struct vid_pos video: Add struct vid_size for width/height mouse: Track last mouse position expo: Store mouse pointer and size in expo expo: Show the mouse when enabled expo: Drop struct scene_obj_bbox in favour of vid_bbox expo: Add damage tracking expo: Set dirty flag when an object bbox changes expo: Add a way to calculate the bbox of dirty objects expo: Add selective rendering for dirty objects in scene expo: Support drawing only the dirty portion of an expo boot/cedit.c | 12 ++- boot/expo.c | 141 ++++++++++++++++++++++++++++++++--- boot/scene.c | 79 +++++++++++++++++++- boot/scene_internal.h | 3 +- cmd/bootflow.c | 12 ++- drivers/input/mouse-uclass.c | 34 +++++++-- include/expo.h | 83 ++++++++++++++++----- include/mouse.h | 23 ++++-- include/video_defs.h | 23 ++++++ test/boot/cedit.c | 21 ++++-- test/dm/mouse.c | 29 ++++--- 11 files changed, 383 insertions(+), 77 deletions(-) -- 2.43.0 base-commit: a3435107db9ff9d6fe1af66859d36b24d0d8b094 branch: prod

[PATCH 00/22] video: Enhancements to support a pointer
by Simon Glass 03 Oct '25

03 Oct '25

From: Simon Glass <sjg(a)chromium.org> The video subsystem has a video_sync() function which does quite a few things and is rather hard to predict and control: - it may or may not actually sync, depending on a timer, etc - it may be called when U-Boot is idle, so any time delays can cause a sync These two problems make it hard to test. This series introduces a deterministic video_manual_sync() which does exactly what it is told, using a set of flags: VIDSYNC_FORCE - the force flag was provided (info for the driver) VIDSYNC_FLUSH - framebuffer changes should be flushed to hardware VIDSYNC_COPY - the copy framebuffer (if any) should be updated The video_sync() method is renamed to sync() and is passed the flags, so that drivers can find out what to do. This allows the sandbox-specific code in video_sync() to move to the driver. These features will (later) be used by expo to provide a better user experience, e.g. to sync only part of the display, or to sync quickly when there is mouse movement. The pointer also needs to be drawn with transparency which is not well supported by the BMP code. This series adds support for a simple transparency colour for now, although an alpha channel may be appropriate in the future. Simon Glass (22): doc: sandbox: Update command-line options documentation sandbox: Add -V flag for video test delay sandbox: Add --video_frames option to capture test frames sandbox: Add a comment for sandbox_sdl_get_mouse_event() video: Add a missing comment in struct video_uc_priv video: Add a pointer image video: Check drawing the mouse pointer video: Move setting of cte in write_pix8() to the top video: Support transparency in the inner bmp functions video: Use variables for each colour component video: Support transparency with 24bpp BMP image video: Support transparency with BMP palette video: Export a function to draw a BMP with transparency video: Add a struct video_bbox for damage tracking video: Rename video_sync() to sync() in struct video_ops video: Tidy up the comment for sync() video: Provide a way for expo to control video sync video: Add flags parameter to sync() operation video: Refactor video_sync() to use video_manual_sync() video: sandbox: Optimise drawing based on damage video: sandbox: Add sync() method for video video: sandbox: Add test for sync() damage rectangle arch/sandbox/cpu/sdl.c | 49 +++- arch/sandbox/cpu/start.c | 32 +++ arch/sandbox/include/asm/sdl.h | 16 +- arch/sandbox/include/asm/state.h | 3 + doc/arch/sandbox/sandbox.rst | 21 +- drivers/video/efi.c | 4 +- drivers/video/images/Makefile | 3 + drivers/video/images/riscos_arrow.bmp | Bin 0 -> 3798 bytes drivers/video/mcde_simple.c | 4 +- drivers/video/sandbox_sdl.c | 36 +++ drivers/video/seps525.c | 4 +- drivers/video/video-uclass.c | 110 ++++++-- drivers/video/video_bmp.c | 121 ++++++--- include/dm/test.h | 15 + include/video.h | 88 ++++-- include/video_defs.h | 37 +++ test/dm/video.c | 376 ++++++++++++++++++++++++-- 17 files changed, 802 insertions(+), 117 deletions(-) create mode 100644 drivers/video/images/riscos_arrow.bmp -- 2.43.0 base-commit: a598eddb938d1b62bba672aacda440c80352fcb7 branch: proc

[PATCH v2 0/9] video: Tidy up embedded graphical images
by Simon Glass 02 Oct '25

02 Oct '25

From: Simon Glass <sjg(a)chromium.org> U-Boot includes a few graphical images which are compiled in, such as the logo and the BGRT logo used for EFI. At present these are handled by a Makefile rule which looks for files ending with '_logo.bmp'. This series moves these into a new drivers/video/images directory and puts them in a linker list, so it is possible to see what images are available. Adding a new image is simpler, just requiring the addition of the normal 'obj-y += file.bmp' rule. This series also adds a new 'video' command which provides the existing 'setcurs' and 'lcdputs' as subcommands, along with documentation and tests. It also adds a more convenient 'write' subcommand. Changes in v2: - Add new patch to switch this command to use hex - Split out docs into its own patch; use video: tag - Pull out the docs into a separate patch - Update test result for hex - Correct confusing output text which should be 16 instead of 10 - Improve docs for row and col - Use Canonical copyright Simon Glass (9): cmd: Update setcurs to use hex doc: video: Add docs for video commands video: Add tests for the video commands video: Add video command with subcommands video: Add a write subcommand video: Support a linker list of images video: Move the logo into the new video-images directory acpi: bgrt: Move the BGRT image into the images directory video: Provide a command to list built-in images cmd/video.c | 96 +++++++++++++- doc/usage/cmd/lcdputs.rst | 58 +++++++++ doc/usage/cmd/setcurs.rst | 57 +++++++++ doc/usage/cmd/video.rst | 120 ++++++++++++++++++ doc/usage/index.rst | 3 + drivers/video/Makefile | 3 +- drivers/video/images/Makefile | 9 ++ .../video/images/bgrt.bmp | Bin .../{u_boot_logo.bmp => images/u_boot.bmp} | Bin drivers/video/video-uclass.c | 20 ++- include/video.h | 46 +++++++ include/video_image.h | 13 ++ lib/acpi/Makefile | 2 - lib/acpi/acpi_extra.c | 22 +--- scripts/Makefile.lib | 42 ++++-- test/dm/video.c | 50 ++++++++ 16 files changed, 494 insertions(+), 47 deletions(-) create mode 100644 doc/usage/cmd/lcdputs.rst create mode 100644 doc/usage/cmd/setcurs.rst create mode 100644 doc/usage/cmd/video.rst create mode 100644 drivers/video/images/Makefile rename lib/acpi/bgrt_image.bmp => drivers/video/images/bgrt.bmp (100%) rename drivers/video/{u_boot_logo.bmp => images/u_boot.bmp} (100%) create mode 100644 include/video_image.h -- 2.43.0 base-commit: e49052511fa82329bf33d7521740eeb24a357607 branch: prob2

[PATCH v2 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. Changes in v2: - Add a log_err() for an invalid state - Update commit message to indicate the bootmeth will always run - Document how the priority was chosen - Add a bit more detail suggested by Heinrich 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 | 277 +++++++++++++++++++++++++++++-- boot/bootmeth-uclass.c | 15 +- boot/bootmeth_efi_mgr.c | 9 + cmd/bootflow.c | 68 +------- doc/develop/bootstd/overview.rst | 40 ++++- include/bootflow.h | 29 +++- include/bootmeth.h | 4 + test/boot/bootflow.c | 73 +++++++- 8 files changed, 419 insertions(+), 96 deletions(-) -- 2.43.0 base-commit: 2617d1179c27ba51e9eb7996b7062a0205c587a9 branch: glob2
