Feedback from v2 lead to the realization that cxl-cli required changes to address the region mode vs decoder mode difference properly. While v2 separated these modes they were not sufficiently separated in the user interface of create-region. This has been corrected in this version. Specifically a new option has been added to cxl create-region. The option requires a decoder mode (DC partition) when the region type is 'dc'. The option is ignored, and can be omitted, for ram and pmem regions. Other libcxl API changes were made to simplify the interface a bit. Documentation was added both at the libcxl and cxl-cli levels. cxl-dcd.sh was cleaned up quite a bit an enhanced. https://github.com/weiny2/ndctl/tree/dcd-region2-2024-11-15 CXL Dynamic Capacity Device (DCD) support is close to landing in the upstream kernel. cxl-cli requires modifications to interact with those devices. This includes creating and operating on DCD regions. cxl-testing allows for quick regression testing as well as helping to design the cxl-cli interfaces. Add preliminary patches with some fixes. Update libcxl, cxl-cli and cxl-test with DCD support.
