# HEAD: 744940f1921c8feb90e3c4bcc1e153fdd6e10fe2 perf/x86/amd/uncore: Pass through error code for initialization failures, instead of -ENODEV
Performance events changes for v6.7 are:
- Add AMD Unified Memory Controller (UMC) events introduced with Zen 4
- Simplify & clean up the uncore management code
- Fall back from RDPMC to RDMSR on certain uncore PMUs
- Improve per-package and cstate event reading
- Extend the Intel ref-cycles event to GP counters
- Fix Intel MTL event constraints
- Improve the Intel hybrid CPU handling code
- Micro-optimize the RAPL code
- Optimize perf_cgroup_switch()
- Improve large AUX area error handling
- Misc fixes and cleanups
Thanks,
Ingo
