patch-sys-boot-efi-loader-arch-amd64-elf64_freebsd.c

Hi,

As written here: https://wiki.freebsd.org/UEFI, this issue is still
encountered on some hardware..

Indeed, I have been able to reproduce the error on a physical machine
(Supermicro X9SRi-F motherboard) when netbooting loader.efi over PXE.

On that machine, this only happens when booting over PXE. I have absolutely no
problem booting locally (so is the MapKey change causing the error related to
the efinet layer ?).

The UEFI specification advises to call ExitBootServices() again if the first
call failed, after having updated the MapKey with a call to GetMemoryMap() just
before the second ExitBootServices() call [1]. The FreeBSD loader only performs
a single attempt and gives up if it fails.

Find attached a patch (for amd64, against -CURRENT r286279) that implements
this second attempt to hand over control to the kernel. It will probably be
necessary to implement the same behaviour for other archs too.

With this patch, my machine can boot over PXE in UEFI mode.

Best regards,
Ganael.
