From c294ac327ca99342b90bd3a83d2cef9b447afaa7 Mon Sep 17 00:00:00 2001 From: Eric Auger Date: Thu, 5 Mar 2020 17:51:45 +0100 Subject: hw/arm/virt: vTPM support Let the TPM TIS SYSBUS device be dynamically instantiable in ARM virt. A device tree node is dynamically created (TPM via MMIO). The TPM Physical Presence interface (PPI) is not supported. To run with the swtmp TPM emulator, the qemu command line must be augmented with: -chardev socket,id=chrtpm,path=swtpm-sock \ -tpmdev emulator,id=tpm0,chardev=chrtpm \ -device tpm-tis-device,tpmdev=tpm0 \ swtpm/libtpms command line example: swtpm socket --tpm2 -t -d --tpmstate dir=/tmp/tpm \ --ctrl type=unixio,path=swtpm-sock Signed-off-by: Eric Auger Reviewed-by: Stefan Berger Tested-by: Ard Biesheuvel Acked-by: Ard Biesheuvel Message-id: 20200305165149.618-7-eric.auger@redhat.com Signed-off-by: Stefan Berger --- hw/arm/virt.c | 7 +++++++ 1 file changed, 7 insertions(+) (limited to 'hw/arm/virt.c') diff --git a/hw/arm/virt.c b/hw/arm/virt.c index 8568085..32d865a 100644 --- a/hw/arm/virt.c +++ b/hw/arm/virt.c @@ -48,6 +48,7 @@ #include "sysemu/numa.h" #include "sysemu/runstate.h" #include "sysemu/sysemu.h" +#include "sysemu/tpm.h" #include "sysemu/kvm.h" #include "hw/loader.h" #include "exec/address-spaces.h" @@ -2083,6 +2084,7 @@ static void virt_machine_class_init(ObjectClass *oc, void *data) machine_class_allow_dynamic_sysbus_dev(mc, TYPE_VFIO_AMD_XGBE); machine_class_allow_dynamic_sysbus_dev(mc, TYPE_RAMFB_DEVICE); machine_class_allow_dynamic_sysbus_dev(mc, TYPE_VFIO_PLATFORM); + machine_class_allow_dynamic_sysbus_dev(mc, TYPE_TPM_TIS_SYSBUS); mc->block_default_type = IF_VIRTIO; mc->no_cdrom = 1; mc->pci_allow_0_address = true; @@ -2196,6 +2198,11 @@ type_init(machvirt_machine_init); static void virt_machine_5_0_options(MachineClass *mc) { + static GlobalProperty compat[] = { + { TYPE_TPM_TIS_SYSBUS, "ppi", "false" }, + }; + + compat_props_add(mc->compat_props, compat, G_N_ELEMENTS(compat)); } DEFINE_VIRT_MACHINE_AS_LATEST(5, 0) -- cgit v1.1
