* clock labeled OD_MCLK
*
* - three <frequency, voltage> points labeled OD_VDDC_CURVE.
- * They can be used to calibrate the sclk voltage curve.
+ * They can be used to calibrate the sclk voltage curve. This is
+ * available for Vega20 and NV1X.
+ *
+ * - voltage offset for the six anchor points of the v/f curve labeled
+ * OD_VDDC_CURVE. They can be used to calibrate the v/f curve. This
+ * is only availabe for some SMU13 ASICs.
*
* - voltage offset(in mV) applied on target voltage calculation.
* This is available for Sienna Cichlid, Navy Flounder and Dimgrey
* E.g., "p 2 0 800" would set the minimum core clock on core
* 2 to 800Mhz.
*
- * For sclk voltage curve, enter the new values by writing a
- * string that contains "vc point clock voltage" to the file. The
- * points are indexed by 0, 1 and 2. E.g., "vc 0 300 600" will
- * update point1 with clock set as 300Mhz and voltage as
- * 600mV. "vc 2 1000 1000" will update point3 with clock set
- * as 1000Mhz and voltage 1000mV.
+ * For sclk voltage curve,
+ * - For NV1X, enter the new values by writing a string that
+ * contains "vc point clock voltage" to the file. The points
+ * are indexed by 0, 1 and 2. E.g., "vc 0 300 600" will update
+ * point1 with clock set as 300Mhz and voltage as 600mV. "vc 2
+ * 1000 1000" will update point3 with clock set as 1000Mhz and
+ * voltage 1000mV.
+ * - For SMU13 ASICs, enter the new values by writing a string that
+ * contains "vc anchor_point_index voltage_offset" to the file.
+ * There are total six anchor points defined on the v/f curve with
+ * index as 0 - 5.
+ * - "vc 0 10" will update the voltage offset for point1 as 10mv.
+ * - "vc 5 -10" will update the voltage offset for point6 as -10mv.
*
* To update the voltage offset applied for gfxclk/voltage calculation,
* enter the new value by writing a string that contains "vo offset".
