Three patches for the CXL PMU driver. Patch 1 is a standalone fix. Patch 2 adds the CXL 4.0 events that hardware exposes but the driver did not. It now precedes the filter work as the latter refers to the new event group IDs. Patch 3 implements Channel/Rank/Bank (CRB) filtering, now permitted for all event groups that CXL 4.0 Table 13-5 allows Filter ID 1 on. v2 was tested on real hardware. The v4 changes have been exercised under qemu CPMU emulation (jic23 tree) + changes for the new events/Filter=1: https://lore.kernel.org/all/20260715190050.458288-1-dave@stgolabs.net/ Thanks!
