9.5.7
9.5.8
• Test extensions permit high-speed population of a target range with a known
pattern
— Selectable hardware-generated fixed patterns: 0, 3, 5, 6, 9, A, C, F
— Hardware generated random pattern capability
— Explicitly stipulated data pattern including ECC
• High speed verification capability
— Selectable write-only, verify-only, or write-read-verify per location
— Logs error location, optional stop and escalate on error detection
• May be made available to the operating system via BIOS for security “clear to 0”
function
System Management Functions
• Full SMBus target support
• Support for remote chassis management via the ICMB architecture
• Serial presence detect of memory devices via standard I²C protocol (accessed via
IICH)
• ACPI and PCI-PM compatible power management
— Includes PME support comprehending PCI Express extensions
• MSI interrupt messaging and redirection support
• Hardware relay of PCI Express legacy mode PCI interrupt messages to IICH
— Supports boot from I/O when IOxAPIC functions are unavailable
RASUM
• SEC/DED ECC protection of external memory DRAM data
• Parity protection on internal data propagated through the IMCH
• CRC on data packets and hardware link-level retry on NSI to the IICH
• 32-bit CRC on data packets and hardware link-level retry on PCI Express ports
• Hardware memory initialization
— True “clear-to-zero” via hardware writes to all populated devices
— Support for hardware-based fast initialization of memory with selectable
patterns
— Support for hardware-based fast verification of memory via accelerated scrub
• Hardware periodic memory scrubbing, including demand scrub support
• Flexible extended error reporting capabilities
• Configurable error containment at I/O interfaces (poison/propagate or stop/
escalate)
• Partial access to internal configuration registers via the TAP port
• Full access to internal configuration registers via SMBus port
