Subject: [PATCH 0/2] EFI facilities
Date: Mon, 21 Jan 2013 20:40:36 +0000 [thread overview]
Message-ID: <1358800838-10459-1-git-send-email-matt@console-pimps.org> (raw)
From: Matt Fleming <matt.fleming@intel.com>
Various users expect different semantics from 'efi_enabled', and one
variable can't be all things to all users. Introduce EFI facilities,
which informs users what EFI initialisation steps were completed
successfully (are the system/config tables mapped, can we invoke
runtime services, etc?) and allows users to clearly document which
pieces of EFI firmware functionality they're using.
The immediate motivation for this patch series is the bug report at,
https://bugzilla.kernel.org/show_bug.cgi?id=47121
Drivers need a new means of detecting whether they're running on an
EFI machine, as sadly the expression,
if (!efi_enabled)
hasn't been a sufficient condition for quite some time.
