33 /*
34  * This file contains definitions for various T4 register value hardware
35  * constants.  The types of values encoded here are predominantly those for
36  * register fields which control "modal" behavior.  For the most part, we do
37  * not include definitions for register fields which are simple numeric
38  * metrics, etc.
39  *
40  * These new "modal values" use a naming convention which matches the
41  * currently existing macros in t4_reg.h.  For register field FOO which would
42  * have S_FOO, M_FOO, V_FOO() and G_FOO() macros, we introduce X_FOO_{MODE}
43  * definitions.  These can be used as V_FOO(X_FOO_MODE) or as (G_FOO(x) ==
44  * X_FOO_MODE).
45  *
46  * Note that this should all be part of t4_regs.h but the toolset used to
47  * generate that file doesn't [yet] have the capability of collecting these
48  * constants.
