v1.4: CXL-Cache / Userspace CLI Tool (update)

This update reflects the voices of Industry partners who cooperate with us.

1. CXL Cache

  • In addition to the usecase that uses CXL device as System RAM and Swap interfaces, SMDK v1.4 allows another usecase that uses CXL device as OS-Level Cache interface.
  • CXL Cache is the 2nd-level page cache with pluggable and page-granularity attributes that stores clean file-backed pages.
    Upon CXL Cache, a file-backed page is traversed in following memory order - pagecache(near), cxlcache(far), disk(farthest).

2. CXL-CLI

  • CXL Spec commands added

identify, get-health-info, set-alert-config, get-alert-config, get-firmware-info, transfer-firmware, activate-firmware

  • CXL Cache control commands added

enable-cxlcache, disable-cxlcache, flush-cxlcache, check-cxlcache


3. Documentation
