From 0a9e72e87e573183d713fca928c75464f829e5a8 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Ky=C3=B6sti=20M=C3=A4lkki?= Date: Sun, 11 Aug 2019 01:22:28 +0300 Subject: arch/x86: Declare permanent_smi_handler() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Advertising SMI triggers in FADT is only valid if we exit with SMI installed. There has been some experiments to delay SMM installation to OS, yet there are new platforms that allow some configuration access only to be done inside SMM. Splitting static HAVE_SMI_HANDLER variable helps to manage cases where SMM might be both installed and cleared prior to entering payload.
