[PATCH 00/22] efi: Improvements for the EFI app on ARM
From: Simon Glass <sjg@chromium.org> This series provides a number of minor improvements for the EFI app when running on ARM machines (on top of Tianocore, for example): - Tidy up various comments - Show the ARM exception level in bdinfo - Tidy up the output of 'meminfo' - Get the addr_find command running - Reduce verbosity when not debugging - Show the model at the top of the diplay when using vidconsole - Allow faking the boot right into the actual OS jump (for debugging) Changes in v2: - Make the messages longer and more explanatory - Use the existing current_el() function - Add a colon so it is clear that 'load_os type' is not a compound term Simon Glass (22): arm: bootm: Add some debugging arm: Fix swtiching typo arm: Show the exception level with bdinfo arm: Drop kernel_entry for arm64 meminfo: Allow for up to 10 hex digits event: Add a dummy function for event_notify() boot: Improve debugging in bootm_load_os() boot: Pass flags to the bootm_final event fdt: Add debugging for fdt_simplefb efi: app: Show only a summary of disks and partitions efi: Fix up the addr_find command efi: app: Tidy up some stale comments in setup_memory() efi: app: Allocate pages in any region efi: app: Pick up the SMBIOS table efi: app: Use EFI_PAGE_SHIFT instead of 12 in free_memory() efi: app: Print the final message before freeing memory efi: app: Use the relocated global_data efi: app: Only show the memory map when debugging efi: app: Add a simplefb node to the devicetree efi: arm: Increase the cyclic timeout again efi: app: Show the model when the vidconsole starts efi: app: Enable the cat command arch/arm/lib/bdinfo.c | 4 ++++ arch/arm/lib/bootm.c | 15 +++++++------ board/efi/efi-arm_app/board.c | 4 ++++ boot/bootm.c | 3 ++- boot/bootm_final.c | 13 ++++++----- boot/fdt_simplefb.c | 4 ++++ cmd/Kconfig | 3 ++- cmd/addr_find.c | 40 +++++++++++---------------------- cmd/meminfo.c | 9 ++++---- configs/efi-arm_app64_defconfig | 5 ++++- include/bootm.h | 13 +---------- include/event.h | 17 +++++++++++++- include/event_decl.h | 27 ++++++++++++++++++++++ lib/Kconfig | 3 ++- lib/efi_client/efi_app.c | 37 +++++++++++++++++++++--------- lib/efi_client/efi_app_init.c | 10 ++++++--- test/cmd/meminfo.c | 2 +- 17 files changed, 135 insertions(+), 74 deletions(-) create mode 100644 include/event_decl.h -- 2.43.0 base-commit: 12f3fc10fd44ee320b79236d7ff0ea3c2d78c12e branch: loadp2

We should not print anything while EFI applications are running. This may mess up the screen output prepared by the application. For instance in Ubuntu we typically use Plymouth and don't want any text output once shim and grub are called. So these printf() should be log_debug() or better EFI_PRINT(). Best regards Heinrich

We should not print anything while EFI applications are running. This may mess up the screen output prepared by the application. For instance in Ubuntu we typically use Plymouth and don't want any text output once shim and grub are called.
Nothing appears from what I can tell. Something (Linux?) prints a message that it is exiting boot services on at ("Exiting boot services..."), but it doesn't happen on x86. I can't always make it appear in any case, but I believe it relates to the console being set to something special, which Ubuntu doesn't do.
So these printf() should be log_debug() or better EFI_PRINT().
There is also the bootstage info which is printed and helps to time the EFI stub. Given the above, I think we should keep this.
Best regards
Heinrich
