AMD Geode™ I/O Companion Device Interface
6.13.3.4 GIO_A20M
GIO_A20M is emulated with an SMI. The processor
receives an SMI from the I/O companion on I/Os that mod-
ify the state of A20M. The SMI handler must then write to
the MSR_A20M (MSR 54002011h) in the GIO to trigger a
real A20M signal back to the processor. When the instruc-
tion completes, A20M is asserted.
6.13.3.5 GIO_NMI
The GIO_NMI signal is the real NMI from the I/O compan-
ion.

6.13.3.6 GIO_INPUT_DIS, GIO_OUTPUT_DIS
GIO_INPUT_DIS and GIO_OUTPUT_DIS are part of the
GLIU power management. They are generic from the pro-
cessor’s perspective, but are defined in the Geode I/O
companion device. Specifically, for the CS5536 they are
defined as SLEEP and DELAYED SLEEP. See the AMD
Geode™ CS5535 or CS5536 Companion Device Data
Book (publication ID 31506 and 33238, respectively) for
details.
6.13.3.7 GIO_INIT
GIO_INIT is triggered via an MSR (MSR 54002013h) in the
GIO (MSR_INT). INIT is used to reset the CPU. It is NOT a
CPU soft reset.
