This bug is awaiting verification that the linux-bluefield/5.4.0-1057.63 kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-focal' to 'verification-done-focal'. If the problem still exists, change the tag 'verification-needed-focal' to 'verification-failed-focal'.
If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.

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.
