From 550862bc1279278a029c8c17871a0c6241c522d8 Mon Sep 17 00:00:00 2001 From: Raymond Mao Date: Fri, 10 Nov 2023 13:25:37 +0900 Subject: [PATCH] efi_loader: Boot var automatic management MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Changes for complying to EFI spec §3.5.1.1 'Removable Media Boot Behavior'. Boot variables can be automatically generated during a removable media is probed. At the same time, unused boot variables will be detected and removed. Please note that currently the function 'efi_disk_remove' has no ability to distinguish below two scenarios a) Unplugging of a removable media under U-Boot b) U-Boot exiting and booting an OS Thus currently the boot variables management is not added into 'efi_disk_remove' to avoid boot options being added/erased repeatedly under scenario b) during power cycles See TODO comments under function 'efi_disk_remove' for more details The original efi_secboot tests expect that BootOrder EFI variable is not defined. With this commit, the BootOrder EFI variable is automatically added when the disk is detected. The original efi_secboot tests end up with unexpected failure. The efi_secboot tests need to be modified to explicitly set the BootOrder EFI variable. squashfs and erofs ls tests are also affected by this modification, need to clear the previous state before squashfs ls test starts.
