struct ErrataListEntryStruct { 
    UInt16 vendID; 
    UInt16 deviceID; 
    UInt16 revisionLo; 
    UInt16 revisionHi; 
    UInt32 errata; 
};

Fields

vendID: The Vendor ID of the device
deviceID: Product ID of device
revisionLo: Lowest product revsion to apply errata to
revisionHi: Highest product revision to apply errata to
errata: Bit field flagging which errata to apply to device.

Discussion

This table contains the list of errata that are necessary for known problems with particular devices. The format is vendorID, product ID, lowest revisionID needing errata, highest rev needing errata, errataBits. The result of all matches is ORed together, so more than one entry may match. Typically for a given errata a list of revisions that this applies to is supplied.
