[PATCH 00/17] expo: Complete mouse operation in the EFI app
by Simon Glass 06 Oct '25

06 Oct '25

From: Simon Glass <sjg(a)chromium.org> This series includes various improvements which allow the mouse to be used when running as an EFI app. In particular: - support for the absolute-pointer protocol, since this provides better integration when running under QEMU - input tweaks to improve performance under QEMU It also includes some x86-specific fixes for i8042 and MTRRs. Finally, a new --bootcmd option is added to the build-qemu script to allow passing a boot command to U-Boot. This series is part F Simon Glass (17): qfw: Export qfw_locate_file() for external use event: Add EVT_BOOTCMD event for custom boot commands x86: qemu: Add EVT_BOOTCMD handler to get bootcmd from fw_cfg scripts: build-qemu: Add --bootcmd option to pass bootcmd via fw_cfg expo: Speed up polling the keyboard x86: efi: Avoid setting MTRRs in the app x86: efi: Disable i8042 in the x86 app efi: app: Support reading SMBIOS3 tables efi: app: Detect running under QEMU efi: serial: Speed up reading from input efi: video: Add some more debugging for the modes efi: mouse: Move simple-pointer code into a function efi: mouse: Move button handling into a function efi: mouse: Split out event handling further efi: Add definitions for the absolute-pointer protocol efi: mouse: Add support for an absolute pointer efi: mouse: Scale the pointer to the display arch/x86/cpu/qemu/qemu.c | 31 +++ arch/x86/lib/init_helpers.c | 3 +- boot/expo.c | 16 +- common/event.c | 1 + common/main.c | 32 ++- doc/board/emulation/script.rst | 15 ++ drivers/input/Kconfig | 2 +- drivers/input/efi_mouse.c | 426 +++++++++++++++++++++++------- drivers/qfw/qfw.c | 4 +- drivers/serial/serial_efi.c | 45 ++-- drivers/video/efi.c | 15 +- include/asm-generic/global_data.h | 6 + include/efi.h | 1 + include/efi_api.h | 30 +++ include/event.h | 22 ++ include/expo.h | 2 + include/qfw.h | 12 + lib/efi/device_path.c | 1 + lib/efi_client/efi_app.c | 33 ++- scripts/build-qemu | 7 + 20 files changed, 574 insertions(+), 130 deletions(-) -- 2.43.0 base-commit: 856580df1b89f25adf9054db39b06d2dade467a4 branch: prof

[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

[PATCH 00/14] expo: Continue development of expo with mouse
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

ARM64 EFI_STUB on SM6115
by Philippe Simons 01 Oct '25

01 Oct '25

I'm currently trying to bring a SM6115 device on Linux but... without much success... I have replaced my ABL with qcomm/abl2eps which allows me to boot an efi application. I've tried to use ARM64 EFI STUB for that but the resulting u-boot-efi-payload.efi doesn't look like an PE32+ binary.... file u-boot-payload.efi u-boot-payload.efi: data Could you help me Thanks
