However, this is not correct since the module is not uniform in all HW blocks, and in this case, the llt_miss block is different from the rest. [Fix] The number of counters present in each block is not fixed, and hence the offsets for the control and data registers should also be calculated accordingly. [Test Case] Without the fix, writing 1 to the llt_miss "enable" file will not result in any of the counters incrementing. With the fix, the counters should increment even with the default event settings. [Regression Potential] Can be considered minimal.
