NAME
Tspi_TPM_GetCapability - get information on the capabilities of the TPM SYNOPSIS
#include <tss/platform.h> #include <tss/tcpa_defines.h> #include <tss/tcpa_typedef.h> #include <tss/tcpa_struct.h> #include <tss/tss_typedef.h> #include <tss/tss_structs.h> #include <tss/tspi.h> TSS_RESULT Tspi_TPM_GetCapability(TSS_HTPM hTPM, TSS_FLAG capArea, UINT32 ulSubCapLength, BYTE* rgbSubCap, UINT32* pulRespDataLength, BYTE** prgbRespData); DESCRIPTION
Tspi_TPM_GetCapability gets information on various capabilities of the TPM. This command can be used to learn how many PCRs the TPM sup- ports, etc. PARAMETERS
hTPM The hTPM parameter is used to specify the handle of the TPM object. capArea The capArea parameter is the flag indicating the attribute to query. Possible values are: ulSubCapLength The ulSubCapLength parameter is the length in bytes of the rgbSubCap parameter. rgbSubCap The rgbSubCap parameter is the data indicating the attribute to query. Possible values are: pulRespDataLength The pulRespDataLength parameter is the length in bytes of the prgbRespData parameter. prgbRespData The prgbRespData parameter receives a pointer to the actual data of the specified attribute. NOTES
The following Capability Areas and Sub-Capability Areas are supported by 1.1 TSS's: TSS_TPMCAP_ORD - query whether an ordinal is supported by the TPM. subCaps: TPM_ORD_* (see tcpa_literals.h) TSS_TPMCAP_FLAG - query for the volatile and non-volatile flags inside the TPM. (Must be owner authorized). In this case, the 2 UINT32 val- ues will be returned concatenated together in prgbRespData. subCaps: ignored. TSS_TPMCAP_ALG - query whether an algorithm is supported by the TPM. subCaps: TSS_ALG_RSA TSS_ALG_DES TSS_ALG_3DES TSS_ALG_SHA TSS_ALG_HMAC TSS_ALG_AES TSS_TPMCAP_PROPERTY - query a property of the TPM. subCaps: TSS_TPMCAP_PROP_PCR TSS_TPMCAP_PROP_DIR TSS_TPMCAP_PROP_MANUFACTURER TSS_TPMCAP_PROP_SLOTS TSS_TPMCAP_VERSION - get the TSS_VERSION structure tha identifies the TPM. subCaps: ignored. RETURN CODES
Tspi_TPM_GetCapability returns TSS_SUCCESS on success, otherwise one of the following values is returned: TSS_E_INVALID_HANDLE hTPM is not a valid handle. TSS_E_INTERNAL_ERROR An internal SW error has been detected. TSS_E_BAD_PARAMETER One or more parameters is bad. CONFORMING TO
Tspi_TPM_GetCapability conforms to the Trusted Computing Group Software Specification version 1.1 Golden SEE ALSO

NAME
Tspi_TPM_PcrExtend - extend a PCR register and optionally write the PCR event log. SYNOPSIS
#include <tss/platform.h> #include <tss/tcpa_defines.h> #include <tss/tcpa_typedef.h> #include <tss/tcpa_struct.h> #include <tss/tss_typedef.h> #include <tss/tss_structs.h> #include <tss/tspi.h> TSS_RESULT Tspi_TPM_PcrExtend(TSS_HTPM hTPM, UINT32 ulPcrIndex, UINT32 ulPcrDataLength, BYTE* pbPcrData, TSS_PCR_EVENT* pPcrEvent, UINT32* pulPcrValueLength, BYTE** prgbPcrValue); DESCRIPTION
Tspi_TPM_PcrExtend extends a PCR register and writes the PCR event log if one is supplied by the user. PARAMETERS
hTPM The hTPM parameter is used to specify the handle of the TPM object. The command to get the TPM to test itself will be sent here. ulPcrIndex The ulPcrIndex parameter is the index of the PCR to extend. ulPcrDataLength The ulPcrDataLength parameter is the length in bytes of the pbPcrData parameter. pbPcrData The pbPcrData parameter is a pointer to data to be hashed by the TSS, which will be used in the extend operation. pPcrEvent The pPcrEvent parameter is the TSS_PCR_EVENT structure to be passed to the TCS to record the extend event. If pPcrEvent is not NULL, the application should fill out the members of the structure that it cares about. pulPcrValueLength The pulPcrValueLength parameter receives the length in bytes of the prgbPcrValue parameter. prgbPcrValue The prgbPcrValue receives a pointer to the memory block containing the PCR data after the extend operation. RETURN CODES
Tspi_TPM_PcrExtend returns TSS_SUCCESS on success, otherwise one of the following values is returned: TSS_E_INVALID_HANDLE hTPM is not a valid handle. TSS_E_INTERNAL_ERROR An internal SW error has been detected. TSS_E_BAD_PARAMETER One or more parameters is bad. CONFORMING TO
Tspi_TPM_PcrExtend conforms to the Trusted Computing Group Software Specification version 1.1 Golden SEE ALSO
