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.
5PARM 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.
2BMM Broken Master Mask. Clear to allow BME (bit 18) to generate an ASMI.
1TARM Target Abort Received Mask. Clear to allow TARE (bit 17) to generate an ASMI.
0MARM Master Abort Received Mask. Clear to allow MARE (bit 16) to generate an ASMI.
