Title:
mlxbf-pmc: Fix crspace event offsets
Status in linux-bluefield package in Ubuntu:
Invalid
Status in linux-bluefield source package in Jammy:
New
Bug description:
SRU Justification:
[Impact]
Currently, the offsets calculated for programming crspace type events on
BlueField-3 are incorrect and this leads to a mismatch of counter numbers
between the driver and actual HW where, for example, event2 in the driver is
actually event4 in HW.
[Fix]
Fix the offset calculation for programming crspace events.
[Test Case]
On a BlueField-3 platform, program any valid event number to the event sysfs
and check that the corresponding counter value increments.
[Regression Potential]
This is a bug fix and the regression potential can be considered minimal.
