Hi, The mlxbf-pmc driver fails to load when the firmware reports a new but not yet implemented performance block. I can reproduce this today with a Bluefield-3 card and UEFI version 4.6.0-18-g7d063bb-BId13035, since this reports the new clock_measure performance block. This[1] patch from Shravan implements the clock_measure support and will solve the issue. But this series avoids the situation by ignoring and logging unsupported performance blocks. NOTE: This series is based on latest linux-next which contains new changes to mlxbf-pmc.
