From fd8caa253c56ed126c09d3b9cc682753ff12218f Mon Sep 17 00:00:00 2001 From: Hal Martin Date: Fri, 12 Aug 2022 15:51:53 +0200 Subject: [PATCH] hw/smbios: support for type 8 (port connector) PATCH v1: add support for SMBIOS type 8 to qemu PATCH v2: incorporate patch v1 feedback and add smbios type=8 to qemu-options internal_reference: internal reference designator external_reference: external reference designator connector_type: hex value for port connector type (see SMBIOS 7.9.2) port_type: hex value for port type (see SMBIOS 7.9.3) After studying various vendor implementationsi (Dell, Lenovo, MSI), the value of internal connector type was hard-coded to 0x0 (None). Example usage: -smbios type=8,internal_reference=JUSB1,external_reference=USB1,connector_type=0x12,port_type=0x10 \ -smbios type=8,internal_reference=JAUD1,external_reference="Audio Jack",connector_type=0x1f,port_type=0x1d \ -smbios type=8,internal_reference=LAN,external_reference=Ethernet,connector_type=0x0b,port_type=0x1f \ -smbios type=8,internal_reference=PS2,external_reference=Mouse,connector_type=0x0f,port_type=0x0e \ -smbios type=8,internal_reference=PS2,external_reference=Keyboard,connector_type=0x0f,port_type=0x0d Signed-off-by: Hal Martin Message-Id: <20220812135153.17859-1-hal.martin@gmail.com> Reviewed-by: Michael S.
