Subject: [Qemu-devel] [seabios PATCH for qemu 2.10 0/2] seabios: build ACPI 1.0-compatible ACPI tables
Date: Wed, 26 Jul 2017 11:42:33 +0200 [thread overview]
Message-ID: <20170726094235.14267-1-pbonzini@redhat.com> (raw)
Old operating systems would like to have a rev1 (ACPI 1.0) FADT, but
new operating systems would like to have rev3 (ACPI 2.0).
Since old operating systems do not know about XSDTs, the
solution is to point the RSDT to a v1 FADT and the XSDT to a
rev3 FADT.
Paolo Bonzini (2):
seabios: build RSDT from XSDT
seabios: create rev1 FADT in compatibility RSDT
