21. **perf: Add sample_flags to indicate the PMU-filled sample data** - Adds flags to indicate when the Performance Monitoring Unit (PMU) has filled the sample data.
22. **powerpc/perf: Add data source encodings for power10 platform** - Adds support for data source encoding on PowerPC power10 platforms.
23. **powerpc/perf: Add encodings to represent data based on newer composite PERF_MEM_LVLNUM* fields** - Adds support for newer memory hierarchy level fields on PowerPC platforms.

25. **powerpc/perf: Fix data source encodings for L2.1 and L3.1 accesses** - Fixes issues with data source encoding for L2.1 and L3.1 cache accesses on PowerPC.
26. **tools/perf: Add mem_hops field in perf_mem_data_src structure** - Adds a field to track memory hops in the perf_mem_data_src structure.
27. **perf: Add mem_hops field in perf_mem_data_src structure** - Similar to the previous patch but likely for a different context or version.
