This patch also restricts the building of the TPM support to i386 and x86_64 targets since both backends I know of, the Xen backend and the libtpms-based backend, will likely only be available for these targets, at least initially. The list can be easily extend. I am trying to prevent that one will end up with support for a frontend but no available backend. v3: - fixed and moved hunks in Makefile.target into right place Signed-off-by: Stefan Berger Index:qemu/Makefile.target =================================================================== --- Makefile.target | 1 + configure | 20 ++++++++++++++++++++ 2 files changed, 21 insertions(+) Index: qemu-git/Makefile.target =================================================================== --- qemu-git.orig/Makefile.target +++ qemu-git/Makefile.target @@ -226,6 +226,7 @@ obj-i386-y += device-hotplug.o pci-hotpl obj-i386-y += debugcon.o multiboot.o obj-i386-y += pc_piix.o kvmclock.o obj-i386-$(CONFIG_SPICE) += qxl.o qxl-logger.o qxl-render.o +obj-i386-$(CONFIG_TPM) += tpm_tis.o # shared objects obj-ppc-y = ppc.o Index: qemu-git/configure =================================================================== --- qemu-git.orig/configure +++ qemu-git/configure @@ -177,6 +177,7 @@ spice="" rbd="" smartcard="" smartcard_nss="" +tpm="no" # parse CC options first for opt do @@ -712,6 +713,8 @@ for opt do ;; --kerneldir=*) kerneldir="$optarg" ;; + --enable-tpm) tpm="yes" + ;; --with-pkgversion=*) pkgversion=" ($optarg)" ;; --disable-docs) docs="no" @@ -941,6 +944,7 @@ echo " --disable-smartcard disable echo " --enable-smartcard enable smartcard support" echo " --disable-smartcard-nss disable smartcard nss support" echo " --enable-smartcard-nss enable smartcard nss support" +echo " --enable-tpm enables an emulated TPM" echo "" echo "NOTE: The object files are built at the place where configure is launched" exit 1 @@ -2610,6 +2614,7 @@ echo "rbd support $rbd" echo "xfsctl support $xfs" echo "nss used $smartcard_nss" echo "OpenGL support $opengl" +echo "TPM support $tpm" if test $sdl_too_old = "yes"; then echo "-> Your SDL version is too old - please upgrade to have SDL support" @@ -3415,6 +3420,21 @@ if test "$gprof" = "yes" ; then fi fi +if test "$tpm" = "yes"; then + has_tpm=0 + if test "$target_softmmu" = "yes" ; then + case "$TARGET_BASE_ARCH" in + i386) + has_tpm=1 + ;; + esac + fi + + if test "$has_tpm" = "1"; then + echo "CONFIG_TPM=y" >> $config_host_mak + fi +fi + linker_script="-Wl,-T../config-host.ld -Wl,-T,\$(SRC_PATH)/\$(ARCH).ld" if test "$target_linux_user" = "yes" -o "$target_bsd_user" = "yes" ; then case "$ARCH" in
