v2.2: CXL Hot Monitoring Unit / CXL-CLI / Bug fix
1. CXL Hotness Monitoring Unit Support (CXL 3.2.8.2.8)
- The CHMU (CXL Hotness Monitoring Unit) is a new CXL feature designed to operate across both a CXL host and device.
It allows a CXL Type 3 device to identify its "hot" memory units by tracking memory access counts.
Software on a CXL host connected to the CXL device can access the hotlist through interfaces defined in the CXL Specification. - Extend the CXL device driver to support CHMU
- Extend the QEMU to enable CHMU emulation
2. Update NDCTL(CXL-CLI): v79 → v80
3. Bug Fix
- Issue no: #31
Fix for a memory leak issue that occurs when the 'use_auto_arena_scaling' allocator option is set to 'false.'
When 'use_auto_arena_scaling' is set to 'false,' the number of arenas is limited to one per pool.
When set to 'true,' arenas are created in proportion to the number of CPUs, as before.
