Description
L2 TLB Retention Timer. Enable retention timer for L2 TLB BIST.
0: Disable.
1: Enable.
L2 TLB Run. Start BIST test on L2 TLB arrays. Should read as 0 because BIST will have
completed before the MSR read can start.
Cache Data Retention Timer. Enable retention timer for cache data array BIST.
0: Disable.
1: Enable.
Cache Data Run. Start BIST test on cache data array. Should read as 0 because BIST will
have completed before the MSR read can start.
Cache Tag Retention Timer. Enable retention timer for cache tag array BIST.
0: Disable.
1: Enable.
Cache Tag Run. Start BIST test on cache tag arrays. Should read as 0 because BIST will
have completed before the MSR read can start.
Description
Reserved. Write as read.
Pause Delay. This field sets the number of clocks for which the bus controller will attempt
to suspend the CPU when a PAUSE instruction is executed. The approximate number of
clocks is PAUSEDLY*8. NOTE that the actual number of clocks that the CPU is sus-
pended will differ from this value, and will vary from pause to pause due to the overhead
of the suspend/unsuspend mechanism and any other CPU activity that would affect how
it responds to suspend requests.
Note also that bit 1 of MSR 00001210h must be set in order for suspend on pause to be
enabled.
Reserved.
General Protection Faults on EXCEPT Flags. Generate general protection faults on
MSR accesses whose response packets have the EXCEPT flag set.
0: Disable.
1: Enable.
