[Qemu-devel] [PATCH] smbios: stop ignoring command line options for TARG


From: Leif Lindholm
Subject: [Qemu-devel] [PATCH] smbios: stop ignoring command line options for TARGET_ARM
Date: Fri, 16 Dec 2016 15:23:19 +0000

Commit c30e1565 ("smbios: implement smbios support for mach-virt")
enabled automatic generation of SMBIOS tables for TARGET_ARM, and
actually provides data for the "virt" machine.

However, do_smbios_option() still had an #ifdef TARGET_I386, preventing
any -smbios command line options from being parsed for any non-x86
targets.
Change this to use a status variable instead of compile-time filtering.

Signed-off-by: Leif Lindholm <address@hidden>

Verified on ARM mach-virt with UEFI shell "smbiosview" command and QEMU
command line parameter -smbios type=0,version=foobar.
