Intel^® Trusted Execution Technology Registers (Intel^® 82Q45 and 82Q43 GMCH Only)
11.1.21 TXT.CMD.CLOSE.LOCALITY1—TXT Close Locality 1
Command
This command closes the locality 1 address space as an TXT range. When closed, the
chipset may decode this range as normal memory space, or it may abort cycles to this
range.
11.1.22 TXT.CMD.OPEN.LOCALITY2—TXT Open Locality 2
Command
This command will open Locality2 for decode as an TXT space by the chipset. This
command is either an LTMW or a private write when private is open.
Note:
OPEN.PRIVATE will open locality 2 and CLOSE.PRIVATE will close locality2. The OPEN/
CLOSE locality2 commands are to be used in the window while PRIVATE is open, but
the MLE wants to close or re-open the locality 2 space while still leaving PRIVATE open.
If the locality is closed, then cycles to the locality 2 address range are not decoded as
TXT cycles. PRIVATE space must also be Open for Locality 2 to be decoded as TXT
space.
11.1.23 TXT.CMD.CLOSE.LOCALITY2—TXT Close Locality 2
Command
This command closes the locality 2 address space as an TXT range. When closed, the
chipset may decode this range as normal memory space, or it may abort cycles to this
range. This command is either an LTMW or a private write when private is open.
