4.4.4.18 THERMTRIP_CONFIG—ThermTrip Configuration Register
This register is used to configure whether the Thermtrip signal only carries the
processor Trip information, or does it carry the Mem trip information as well. The
register will be used by HW to enable ORing of the memtrip info into the thermtrip OR
tree.
4.4.4.19 PERFMON_PCODE_FILTER—Perfmon Pcode Filter Register
This register has three mappings depending on the type of Perfmon Events that are
being counted.
This register is read by Pcode and communicates the Masking information from the
BIOS/SW to Pcode.

Enable MEM Trip
1 = PCU will OR in the MEMtrip information into the ThermTrip OR Tree
0 = PCU will ignore the MEMtrip information and ThermTrip will just have the
processor indication.
Expect BIOS to Enable this in Phase 4.
