22 * current PROM. The OS uses sn_prom_feature_available(feature) to test for
23 * the presence of a PROM feature. Down rev (old) PROMs will always test
24 * "false" for new features.

36 /* --------------------- OS Features -------------------------------*/
39 * The following defines OS features that are optionally present in
40 * the operating system.
41 * During boot, PROM is notified of these features via a series of calls:
43 * ia64_sn_set_os_feature(feature1);
45 * Once enabled, a feature cannot be disabled.
47 * By default, features are disabled unless explicitly enabled.
49 * These defines must be kept in sync with the corresponding
50 * PROM definitions in feature_sets.h.
