GLD_MSR_SMI Bit Descriptions
Bit Name Description
63:22 RSVD (RO) Reserved (Read Only). Reserved for future use.
21 PARE Parity Error Event (Read/Write-1-to-Clear). This bit is asserted due to detection of a
PCI bus parity error. Write 1 to clear. PS (MSR 50002010h[27]) must be set to enable this
event. The event causes an ASMI if PARM (bit 5) is cleared.
20 SYSE System Error Event (Read/Write-1-to-Clear). This bit is asserted due to the detection
of a PCI bus system error. Write 1 to clear. PS (MSR 50002010h[27]) must be set to
enable this event. The event causes an ASMI if SYSM (bit 4) is cleared.
19 VPHE Virtual PCI Header Event (Read/Write-1-to-Clear). This bit is set by Virtual PCI Header
support logic, write 1 to clear. The event causes an SSMI if VPHM (bit 3) is cleared.
18 BME Broken Master Event (Read/Write-1-to-Clear). This bit is asserted due to detection of a
broken PCI bus master. Write 1 to clear. BMS (MSR 50002010h[26]) must be set to
enable this event. The event causes an ASMI if BMM (bit 2) is cleared.
17 TARE Target Abort Received Event (Read/Write-1-to-Clear). This bit is asserted due to
reception of target abort on PCI. Write 1 to clear. TARS (MSR50002010h[25]) must be
set to enable this event. The event causes an ASMI if TARM (bit 1) is cleared.
16 MARE Master Abort Received Event (Read/Write-1-to-Clear). This bit is asserted due to
reception of master abort on PCI. Write 1 to clear. MARS (MSR 50002010h[24]) must be
set to enable this event. The event causes an ASMI if MARM (bit 0) is cleared.
15:6 RSVD Reserved. Reserved for future use.
5 PARM Parity Error Mask. Clear to allow PARE (bit 21) to generate an ASMI.
4 SYSM System Error Mask. Clear to allow SYSE (bit 20) to generate an ASMI.
3 VPHM Virtual PCI Header Mask. Clear to allow SSMI flag to be set in selected GLIU response
packets. I/O reads and writes to location 0CFCh may cause an SSMI depending upon
the configuration of this bit and the GLPCI_PBUS (MSR 50002012h) model specific reg-
isters.
2 BMM Broken Master Mask. Clear to allow BME (bit 18) to generate an ASMI.
1 TARM Target Abort Received Mask. Clear to allow TARE (bit 17) to generate an ASMI.
0 MARM Master Abort Received Mask. Clear to allow MARE (bit 16) to generate an ASMI.
