Memory Combined Rd/Wr Thermal Weight Hot-6
Threshold (MemCRWTWHotM6Th)
The Hot-6 thermal weight threshold used for memory
combined Rd/Wr thermal weight tracking. This 16-bit
value is compared to the MSB (i.e., [38:23]) of the
thermal weight counter value, to determine whether the
HOT-6 thermal weight threshold is reached or not.
This threshold level should be set lower than the Hot to
Hot-5 threshold, but higher than the Hot-7 threshold
level. Since there are 8 NearHot-to-Hot levels defined,
the minimum that this field should be set to is 0002h, to
avoid overlapping levels if all 8 NearHot-to-Hot thresholds
are to be used. Similarly, the maximum that this field can
be set to is FFF9h, if all 8 NearHot-to-Hot thresholds are
to be used. Overlapping levels can certainly be set when
less than 8 thresholds are to be used. To use 1 threshold
setting only, effectively disabling adaptive throttling, all 8
thresholds can be set to the same value.
Memory Combined Rd/Wr Thermal Weight Hot-7
Threshold (MemCRWTWHotM7Th)
The Hot-7 thermal weight threshold used for memory
combined Rd/Wr thermal weight tracking. This 16-bit
value is compared to the MSB (i.e., [38:23]) of the
thermal weight counter value, to determine whether the
HOT-7 thermal weight threshold is reached or not.
This threshold level should be set lower than the Hot to
Hot-6 threshold. Since there are 8 NearHot-to-Hot levels
defined, the minimum that this field should be set to is
0001h, to avoid overlapping levels if all 8 NearHot-to-Hot
thresholds are to be used. Similarly, the maximum that
this field can be set to is FFF8h, if all 8 NearHot-to-Hot
thresholds are to be used. Overlapping levels can
certainly be set when less than 8 thresholds are to be
used. To use 1 threshold setting only, effectively disabling
adaptive throttling, all 8 thresholds can be set to the
same value.
