[Qemu-devel] [PATCH v5.2 for 2.13 0/4] tpm: Extend TPM with state migration support |

This series of patches implements support for migrating the state of the
external 'swtpm' TPM emulator as well as that of the TIS interface.
For testing of TPM 2 (migration) please use the following git repos and
branches:
libtpms:
- repo: https://github.com/stefanberger/libtpms
- branch: tpm2-preview.rev146.v2
swtpm:
- repo: https://github.com/stefanberger/swtpm
- branch: tpm2-preview.rev146.v2
Regards,
Stefan
Changes:
v4->v5:
- followed Marc-André's and Alan's comments where possible; some comments
were not addressed and reasons posted to mailing list
- converted debug statements to tracing
- qemu_chr_fe_read_all does not return errno, so displaying expected versus
received number of bytes rather than strerror(errno)
- added test cases
- added documentation for migration to docs/spec/tpm.txt
v3->v4:
- dropped the size limit enforcement on blobs received from the swtpm
- the .post_load migration function requires errno's to be returned.
-> some of the functions have been converted to return a better errno

docs: tpm: add VM save/restore example and troubleshooting guide
tpm: Add test cases that uses the external swtpm with CRB interface
