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 Stefan Berger (4): 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: tpm: Add example command line for ppc64 and tpm-spapr docs/specs/tpm.txt | 20 +- hw/ppc/Kconfig | 1 + hw/tpm/Kconfig | 6 + hw/tpm/Makefile.objs | 1 + hw/tpm/tpm_spapr.c | 470 +++++++++++++++++++++++++++++++++++++++++++ hw/tpm/trace-events | 14 ++ include/sysemu/tpm.h | 3 + qapi/tpm.json | 6 +- 8 files changed, 517 insertions(+), 4 deletions(-) create mode 100644 hw/tpm/tpm_spapr.c
