<Event Device="CPU0" Type="MEMW" ICount="3133971259" Address="00000000000A88B2" Size="1">

<Data Length="1" Value="01" /> </Event>

Defines a Memory Read or Memory Write event. MEMR and MEMW are recorded for MMIO ranges.

7.22.2.2 XTR Binary File Contents

XTR Binary file contains the memory image of the system just before the XTR Record started. The binary file contains multiple records where each record contains has the following structure:

Physical Address Of the Page: 8 bytes

Count of Bytes in this Page: 4 Bytes

Data Of the Page: Count of Bytes earlier

Currently XTR only supports page size of 4096 bytes. Both the DIMM and MMIO may be present in the XTR Binary file. The last record in the binary file must have a count of zero to indicate end of memory image.

7.22.3 ModeFlags

ModeFlags defines some of the states of the CPU that are important for execution. The upper 32 bits store the Execution Control flags e.g. HLT and <ignore interrupts for 1 instruction when we change stack segment>. The lower 32 bits is redundant from other initialization values in the XTR initialization but is there to maintain code consistency.

Table 7-7shows the Execution Control Flags (upper 32 bit):
