They are not useful yet, and the kernel 5.1 HMAT sysfs doesn't show SMBIOS entries. We can update it if it useful in the future.+ + /* SMBIOS Handles */ + /* TBD: set smbios handles */ + build_append_int_noprefix(table_data, 0, 2 * n);Is memory side cache structure useful at all without pointing to SMBIOS entries?
