MCA Interface for Drivers

The Intel generic HALs provide the following Intel Pentium Pro and Itanium technology MCA-specific interface for drivers:

  • HalSetSystemInformation with the HAL_QUERY_INFORMATION_CLASS parameter set to HalMcaRegisterDriver. This allows a driver to register MCA callbacks with the HAL. Additionally, the Itanium driver can use a HAL_QUERY_INFORMATION_CLASS parameter set to HalCmcRegisterDriver or HalCpeRegisterDriver for delivery of Corrected CPU errors (CMC) and Corrected Platform Errors (CPE).

  • HalQuerySystemInformation with the HAL_QUERY_INFORMATION_CLASS parameter set to HalMcaLogInformation. This allows a driver to read the MCA log. Additionally, the Itanium driver can use a HAL_QUERY_INFORMATION_CLASS parameter set to HalCmcLogInformation or HalCpeLogInformation to read MCA logs from CMCs and CPEs.

Note   Windows Vista and later versions of Windows do not support the type of Machine Check Architecture (MCA) and Machine Check Exception (MCE) reporting that is described in this topic. MCA and MCE reporting are supported through Windows Hardware Error Architecture (WHEA) instead.
