Subject: [PATCH] Fix exit back to EFI firmware
|
|
|
39700a |
|
|
|
39700a |
Arm/AArch64 machines set up a timer event which is not getting
|
|
|
39700a |
canceled when returning to firmware. This is because grub_exit()
|
|
|
39700a |
calls grub_efi_fini() instead of grub_machine_fini(). The latter
|
|
|
39700a |
will shutdown the timer (and other machine-specific things) as
|
|
|
39700a |
well as make the call to grub_efi_fini().
