1. CXL Hotness Monitoring Unit Support (CXL 3.2.8.2.8)
- The CXL Hotness Monitoring Unit (CHMU) is an interface that allows software running on CXL hosts to identify the ‘hot’ memory ranges in CXL memory devices in terms of memory access counts.
- Added a CXL device driver to support CHMU and an emulation function based on QEMU.
2. Update NDCTL(CXL_CLI): v79 → v80
3. Bug Fix
- Fix for memory leak issue occuring when setting the 'use_auto_arena_scaling' allocator option to 'false'.
- When 'use_auto_arena_scaling option' is set to false, the number of arenas is 1 per pool)
(When 'true', the arena is generated in proportion to the number of CPUs as before)
