TrouSerS is a Common Public License (CPL) licensed TSS that enables multiple applications to
simultaneously access and use the TPM without requiring the applications to explicitly
synchronize access. HP-UX TCS complies with the TSS 1.1 Golden specification.
Architecture
At the lowest level, HP-UX TCS hardware support includes a header and the necessary bus logic
and firmware to support a TPM. The TPM is physically attached as a core I/O device. Figure 1-2
illustrates the architecture of the HP-UX TCS stack.
