4.2.1.3 GLD SMI MSR (GLD_MSR_SMI)
The flags are set with internal conditions. The internal conditions are always capable of setting the flag, but if the mask is 1,
the flagged condition will not trigger the SMI signal. Reads to the flags return the value. Write = 1 to the flag, clears the
value. Write = 0 has no effect on the flag.
MSR Address GLIU0: 10002002h
GLIU1: 40002002h
Type R/W
Reset Value 00000000_00000001h

GLD _MSR_SMI Bit Descriptions
Bit Name Description
63:37 RSVD Reserved.
36 SFLAG4 SMI Flag4. If high, records that an SMI was generated due to a Statistic Counter 3
(GLIU0 MSR 100000ACh, GLIU1 MSR 400000ACh) event. Write 1 to clear; writing 0 has
no effect. SMASK4 (bit 4) must be low to generate SMI and set flag.
35 SFLAG3 SMI Flag3. If high, records that an SMI was generated due to a Statistic Counter 2
(GLIU0 MSR 100000A8h, GLIU1 MSR 400000A8h) event. Write 1 to clear; writing 0 has
no effect. SMASK3 (bit 3) must be low to generate SMI and set flag.
34 SFLAG2 SMI Flag2. If high, records that an SMI was generated due to a Statistic Counter 1
(GLIU0 MSR 100000A4h, GLIU1 MSR 400000A4h) event. Write 1 to clear; writing 0 has
no effect. SMASK2 (bit 2) must be low to generate SMI and set flag.
33 SFLAG1 SMI Flag1. If high, records that an SMI was generated due to a Statistic Counter 0
(GLIU0 MSR 100000A0h, GLIU1 MSR 400000A0h) event. Write 1 to clear; writing 0 has
no effect. SMASK1 (bit 1) must be low to generate SMI and set flag.
32 SFLAG0 SMI Flag0. Unexpected Type (HW Emulation).
31:5 RSVD Reserved.
4 SMASK4 SMI Mask4. Write 0 to enable SFLAG4 (bit 37) and to allow a Statistic Counter 3 (GLIU0
MSR 100000ACh, GLIU1 MSR 400000ACh) event to generate an SMI.
3 SMASK3 SMI Mask3. Write 0 to enable SFLAG3 (bit 36) and to allow a Statistic Counter 2 (GLIU0
MSR 100000A8h, GLIU1 MSR 400000A8h) event to generate an SMI.
2 SMASK2 SMI Mask2. Write 0 to enable SFLAG2 (bit 34) and to allow a Statistic Counter 1 (GLIU0
MSR 100000A4h, GLIU1 MSR 400000A4h) event to generate an SMI.
1 SMASK1 SMI Mask1. Write 0 to enable SFLAG1 (bit 33) and to allow a Statistic Counter 0 (GLIU0
MSR 100000A0h, GLIU1 MSR 400000A0h) event to generate an SMI.
0 SMASK0 SMI Mask0. Unexpected Type (HW Emulation).
