These charts are intended to serve two quite unrelated purposes. The first is to allow someone who has a particular PC TPM to discover which commands will definitely be supported, which won't, and which may or may not be, depending on the manufacturer. The second is to provide a convenient reference for implementers using multiple TPM versions or programming abstraction levels. The first chart is organized by TPM 1.2 commands. For each command, the chart indicates whether the command is required; the TSS 1.2 TSPI functions, if any, that provide equivalent or overlapping functionality; and the TPM 2.0 commands which are the closest equivalents, if any are close at all. In some cases, where TPM 2.0 has introduced new but related functionality, I'm including it, so that those interested can look into the details and decide if it's useful to them. The second chart is organized by TPM 2.0 commands. For each command, the chart indicates whether the command is required. Note that many TPM 2.0 commands show up in the second chart but not the first; these are commands for which there is no real 1.2 equivalent.
