MSR Address
Type
Reset Value
IF_CONFG_MSR controls the operation of the Instruction Fetch (IF). The Level-0 COF cache (Change of Flow (COF)
cache), L1 COF cache, return stack, and power saving mode may be turned on or off. The WRMSR instruction can access
IF_CONFIG MSR at any time. Devices external to the CPU should issue writes to IF_CONFIG MSR only if the CPU is sus-
pended or stalled.

Description
Reserved.
Branch Tree Messaging (BTM) Exception Type. Allow the BTM stream to contain
exception type records.
0: Enable. (Default)
1: Disable.
Branch Tree Messaging Interrupt Vector. Allow the BTM stream to contain interrupt
vector records.
0: Enable. (Default)
1: Disable.
Linear Snooping.
0: Enable. (Default)
1: Disable.
Physical Snooping.
0: Enable. (Default)
1: Disable.
Reserved.
Branch Tree Messaging Sync Period. Specifies the maximum period between BTM
synchronization records. If BSP is non-zero, the IF will insert a synchronization record
into the BTM stream whenever it sees a series of 32*BSP non-synchronization records.
(Default = 0)
Reserved.
Branch Target Buffer (BTB) Way. Each bit is used to disable one Way of the BTB. Bit
32 = Way 0, bit 33 = Way 1, bit 34 = Way 2, and bit 35 = Way 3.
0: Enable Way. (Default)
1: Disable Way.
