GLD SMI MSR (GLD_MSR_SMI)
This MSR contains the SMI and Mask bits for the GP. An SMI is asserted whenever an illegal address or an illegal type is
detected on the GLIU and the mask bit is not set. This also causes the mb_p_asmi output to be asserted. This signal
remains asserted until the SMI is cleared or the mask bit is set. An illegal address is defined as a memory mapped access
to an address offset greater than 07Fh or an MSR access to an address greater than 20000007h. An illegal type is flagged
if the GP receives a transaction whose type is not one of the following: NCOH_READ, NCOH_WRITE, NCOH_READ_BEX,
MSR_READ, MSR_WRITE, BEX, NULL.
detected on the GLIU and the mask bit is not set. This also causes the mb_p_asmi output to be asserted. This signal
remains asserted until the SMI is cleared or the mask bit is set. An illegal address is defined as a memory mapped access
to an address offset greater than 07Fh or an MSR access to an address greater than 20000007h. An illegal type is flagged
if the GP receives a transaction whose type is not one of the following: NCOH_READ, NCOH_WRITE, NCOH_READ_BEX,
MSR_READ, MSR_WRITE, BEX, NULL.
6.4.1.4
GLD Error MSR (GLD_MSR_ERROR)
This MSR contains the Errors and Mask bits for the GP. An error is asserted whenever an illegal address or an illegal type
is detected on the GLIU and the mask bit is not set. This also causes the internal mb_p_asmi output to be asserted if the
Mask bit (MSR A0002002h[0]) is not set. The error bits remain asserted until they are cleared. An illegal address is defined
as a memory mapped access to an address offset greater than 07Fh or an MSR access to an address greater than
20000007h. An illegal type is flagged if the GP receives a transaction whose type is not one of the following: NCOH_READ,
NCOH_WRITE, NCOH_READ_BEX, MSR_READ, MSR_WRITE, BEX, NULL.
is detected on the GLIU and the mask bit is not set. This also causes the internal mb_p_asmi output to be asserted if the
Mask bit (MSR A0002002h[0]) is not set. The error bits remain asserted until they are cleared. An illegal address is defined
as a memory mapped access to an address offset greater than 07Fh or an MSR access to an address greater than
20000007h. An illegal type is flagged if the GP receives a transaction whose type is not one of the following: NCOH_READ,
NCOH_WRITE, NCOH_READ_BEX, MSR_READ, MSR_WRITE, BEX, NULL.
