This section specifies the checks on the fields for CS, SS, DS, ES, FS, GS, TR, and LDTR.
|
|
|
|
|
|
|
|
|
|
* Selector fields.
|
|
|
|
|
|
|
|
|
|
- TR. The TI flag (bit 2) must be 0.
|
|
|
|
|
- LDTR. If LDTR is usable, the TI flag (bit 2) must be 0. (windows does not use LDT!)...
|
|
|
|
|
- SS. If the guest will not be virtual-8086 and the “unrestricted guest” VM-execution control is 0, the RPL
|
|
|
|
|
(bits 1:0) must equal the RPL of the selector field for CS.
|
|
|
|
|
|
|
|
|
|
* Base-address fields.
|
|
|
|
|
|
|
|
|
|
- TR, FS, GS. The address must be canonical.
|
|
|
|
|
- CS. Bits 63:32 of the address must be zero.
