Platform CrashLog

  • The CrashLog feature is intended for use by system builders (OEMs) as a means to triage and perform first level debug of failures.
  • CrashLog enables the BIOS or the OS to collect data on failures with the intent to collect and classify the data as well as analyze failure trends.
  • CrashLog is a mechanism to collect debug information into a single location and then allow access to that data via multiple methods, including the BIOS and OS of the failing system.
  • CrashLog is initiated by a Crash Data Detector on observation of error conditions (TCO watchdog timeout, machine check exceptions, etc.).
  • Crash Data Detector notifies the Crash Data Requester of the error condition in order for the Crash Data Requester to collect Crash Data from several different IPs and/or Crash Nodes and stores the data to the Crash Data Storage (on-die SRAM) prior to the reset.
  • After the system has rebooted, the Crash Data Collector reads the Crash Data from the Crash Data Storage and makes the data available to either to software and/or back to a central server to track error frequency and trends.
