Doesn't work with 6.5 kernel on macbookpro13,1 #194

Closed xeron closed 2 months ago

xeron commented 12 months ago

So I was experimenting with Linux on macbookpro13,1. I know it might have weird Apple EFI but what I encountered is:

But /sys/firmware/efi/efivars is present on both kernel versions.

On 6.5 strace efibootmgr shows something like this:

statfs("/sys/firmware/efi/efivars", ...) ... EINVAL ...
...("/sys/firmware/efi/vars") ... ENOENT (No such file or directory)

Seems like it's a kernel bug.

I have MacBookPro17,1 and efibootmgr 18 also /sys/firmware/efi/efivars but no luck, EFI variables are not supported on this system.

# ls /sys/firmware/efi/efivars/

Try newer kernel. It was fixed at some point.
