+# SVSTATE SPR
+
+The format of the SVSTATE SPR is as follows:
+
+| Field | Name     | Description           |
+| ----- | -------- | --------------------- |
+| 0:6   | maxvl    | Max Vector Length     |
+| 7:13  |    vl    | Vector Length         |
+| 14:20 | srcstep  | for srcstep = 0..VL-1 |
+| 21:27 | dststep  | for dststep = 0..VL-1 |
+| 28:29 | dsubstep | for substep = 0..SUBVL-1  |
+| 30:31 | ssubstep | for substep = 0..SUBVL-1  |
+| 32:33 | mi0      | REMAP RA SVSHAPE0-3    |
+| 34:35 | mi1      | REMAP RB SVSHAPE0-3    |
+| 36:37 | mi2      | REMAP RC SVSHAPE0-3    |
+| 38:39 | mo0      | REMAP RT SVSHAPE0-3    |
+| 40:41 | mo1      | REMAP EA SVSHAPE0-3    |
+| 42:46 | SVme     | REMAP enable (RA-RT)  |
+| 47:52 | rsvd     | reserved              |
+| 53    | pack     | PACK (srcstrp reorder)  |
+| 54    | unpack   | UNPACK (dststep order)  |
+| 55:61 | hphint   | Horizontal Hint       |
+| 62    | RMpst    | REMAP persistence     |
+| 63    | vfirst   | Vertical First mode   |
+
+Notes:
+
+* The entries are truncated to be within range.  Attempts to set VL to
+  greater than MAXVL will truncate VL.
+* Setting srcstep, dststep to 64 or greater, or VL or MVL to greater
+  than 64 is reserved and will cause an illegal instruction trap.
