Virtual hardware would be cheap :-) I tested this series with QEMU + vTPM + SeaBIOS with TPM 1.2 + TPM 2 support (basing the log on ACPI). I had to fix an endianess issue on the SeaBIOS side, which made it work. So for this version of the patches I can give it my tested-by: Tested-by: Stefan Berger > > /Jarkko > > ------------------------------------------------------------------------------ > _______________________________________________ > tpmdd-devel mailing list > tpmdd-devel@lists.sourceforge.net > https://lists.sourceforge.net/lists/listinfo/tpmdd-devel >
