From 5876d9b53fee5fc5a341fad1618cf3a9731206da Mon Sep 17 00:00:00 2001 From: Igor Mammedov Date: Wed, 8 Jun 2022 09:53:21 -0400 Subject: [PATCH] acpi: ipmi: use AcpiDevAmlIf interface to build IPMI device descriptors convert ad-hoc way we use to generate AML for ISA/SMB IPMI devices to a generic approach (i.e. make devices provide its own AML blobs like it is done with other ISA devices (ex. KBD)) Signed-off-by: Igor Mammedov Acked-by: Gerd Hoffmann Message-Id: <20220608135340.3304695-17-imammedo@redhat.com> Reviewed-by: Michael S. Tsirkin Signed-off-by: Michael S.
