Thanks Bryant, this problem has been solved by following "http://www.mail-archive.com/address@hidden/msg200808.html". But there is another problem when run configure with "./configure --target-list=x86_64-softmmu --enable-tpm". The value of "libtpms" is still "no". when I modified "tpm_libtpms" to "yes" in configure file directly and make, then reported with error "hw/tpm/tpm_libtpms.c:21:33: fatal error: libtpms/tpm_library.h: No such file or directory". Now I am installing libtpms with https://github.com/coreycb/libtpms for libtpms lib. Could you share specific step to configure QEMU based on your patch, if it comes easily to you?
Here's what I've been using to build libtpms:$ CFLAGS='-O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector --param=ssp-buffer-size=4 -m64 -mtune=generic'
$ export CFLAGS$ ./configure --build=x86_64-redhat-linux-gnu --prefix=/usr --libdir=/usr/lib64
$ make $ sudo make install And then the configure you're using above should work for QEMU.
BTW, one target of my team is enabling stubdom vtpm for HVM virtual machine on Xen virtualization, your patches and seabios are big breakthroughs. My team is very interested to collaborate with you / Qemu community on similar areas.
That's great to hear!Unfortunately, the current approach of linking QEMU against libtpms doesn't look like it's going to make it upstream. So it looks like we need to take a different approach.
Btw, I thought Xen already had TPM support. Is that not supported in stubdom's?

I'd be really pleased if you can help me on these issues.

Thanks. Quan Xu IntelThanks Quan. I believe I built these on top of commit c2d30667760e3d7b81290d801e567d4f758825ca. I don't think this series is going to make it upstream though so I likely won't be submitting a v2. -- Regards, Corey Bryant
