It can be tested as follows with swtpm/libtpms: mkdir /tmp/mytpm1 swtpm socket --tpmstate dir=/tmp/mytpm1 \ --ctrl type=unixio,path=/tmp/mytpm1/swtpm-sock \ --log level=20 If TPM 2 is desired, add --tpm2 as parameter to the above.

Gibson v4->v5: - use runstate_check(RUN_STATE_FINISH_MIGRATE) to check whether devices are suspending; ditch 3 patches in this series that tried to do similar v3->v4: - addressed comments to v3 - reworked suspend/resume support that requires extensions to backends v2->v3: - patch 1: a TPM 2 is identified by IBM,vtpm20 in the compatible node - patch 1: convert to tracing to display Tx and Rx buffers - added documentation patch - added patch to enable TPM device as part of pSeries v1->v2: - followed Cedric Le Goater's suggestions to patch 1 - send appropriate CRQ error responses if DMA read or write fails - renamed tpm_spapr_got_payload to tpm_spapr_process_cmd and pass endianess-adjusted data pointer from CRQ to it Regards, Stefan Marc-André Lureau (1): docs/specs/tpm: reST-ify TPM documentation Stefan Berger (5): tpm: Move tpm_tis_show_buffer to tpm_util.c spapr: Implement get_dt_compatible() callback tpm_spapr: Support TPM for ppc64 using CRQ based interface tpm_spapr: Support suspend and resume hw/ppc/Kconfig: Enable TPM_SPAPR as part of PSERIES config docs/specs/index.rst | 1 + docs/specs/tpm.rst | 503 +++++++++++++++++++++++++++++++++++++ docs/specs/tpm.txt | 427 ------------------------------- hw/ppc/Kconfig | 1 + hw/ppc/spapr_vio.c | 11 +- hw/tpm/Kconfig | 6 + hw/tpm/Makefile.objs | 1 + hw/tpm/tpm_spapr.c | 443 ++++++++++++++++++++++++++++++++ hw/tpm/tpm_tis.c | 32 +-- hw/tpm/tpm_util.c | 25 ++ hw/tpm/tpm_util.h | 3 + hw/tpm/trace-events | 16 +- include/hw/ppc/spapr_vio.h | 1 + include/sysemu/tpm.h | 3 + qapi/tpm.json | 6 +- 15 files changed, 1018 insertions(+), 461 deletions(-) create mode 100644 docs/specs/tpm.rst delete mode 100644 docs/specs/tpm.txt create mode 100644 hw/tpm/tpm_spapr.c
