Have you considered that some firmwares brick if EFI storage is over 50% full? Why not having a file on ESP instead? Le jeu. 27 juil. 2023, 00:09, Glenn Washburn a écrit : > This patch series (for me) was motivated by the "gdb: Add more support for > debugging on EFI platforms" patch series, whi

[PATCH 4/4] efi: Print GDB command for loading symbols if variable exists

If the variable "enable_earlyinit_gdbinfo" exists, print the GDB command needed to properly load symbols in an attached GDB session. This variable must come from the environment block stored in the GRUB_ENV EFI variable, which allows this to get printed as early as possible. Signed-off-by: Glenn W

[PATCH 0/4] EFI envblk

This patch series (for me) was motivated by the "gdb: Add more support for debugging on EFI platforms" patch series, which allowed printing in early EFI init of the GDB command for properly loading symbols. That approach of having the functionality be included at compile time was ultimately rejecte

[PATCH 1/4] efi: Load env block from GRUB_ENV EFI variable in early init

From: Peter Jones This allows setting GRUB variables before any user interaction or GRUB script can run. It is primarily intended to be used to turn on early debugging. Signed-off-by: Peter Jones Replace grub_efi_guid_t -> grub_guid_t Signed-off-by: Glenn Washburn --- grub-core/Makefile.core.

[PATCH 2/2] docs: A note to cat that hexdump should be used for binary data

The cat command should not be used to print binary data because it can show bytes not in the binary data and not show bytes that are in the data, which can lead to confusion. This happens because cat does some processing of the data stream, namely trying to decode substrings as UTF-8. Signed-off-b

RFC: Signed grub extension images

Hi, after some thinking about device trees and secure boot today, I pondered if we should just allow wrapping a filesystem image in a signed PE binary into a "grubext" section perhaps. Use cases can be: - signed fonts packages - signed themes packages - signed device trees This probably needs so
