- * Support Intel RAPL energy consumption counters
- * Copyright (C) 2013 Google, Inc., Stephane Eranian
- *
- * Intel RAPL interface is specified in the IA-32 Manual Vol3b
- * section 14.7.1 (September 2013)
- *
- * RAPL provides more controls than just reporting energy consumption
- * however here we only expose the 3 energy consumption free running
- * counters (pp0, pkg, dram).
- *
- * Each of those counters increments in a power unit defined by the
- * RAPL_POWER_UNIT MSR. On SandyBridge, this unit is 1/(2^16) Joules
- * but it can vary.
- *
- * Counter to rapl events mappings:
- *
- *  pp0 counter: consumption of all physical cores (power plane 0)
- * 	  event: rapl_energy_cores
- *    perf code: 0x1
- *
- *  pkg counter: consumption of the whole processor package
- *	  event: rapl_energy_pkg
- *    perf code: 0x2
- *
- * dram counter: consumption of the dram domain (servers only)
- *	  event: rapl_energy_dram
- *    perf code: 0x3
- *
- * gpu counter: consumption of the builtin-gpu domain (client only)
- *	  event: rapl_energy_gpu
- *    perf code: 0x4
- *
- *  psys counter: consumption of the builtin-psys domain (client only)
- *	  event: rapl_energy_psys
- *    perf code: 0x5
- *
- * We manage those counters as free running (read-only). They may be
- * use simultaneously by other tools, such as turbostat.
- *
- * The events only support system-wide mode counting. There is no
- * sampling support because it does not make sense and is not
- * supported by the RAPL hardware.
- *
- * Because we want to avoid floating-point operations in the kernel,
- * the events are all reported in fixed point arithmetic (32.32).
- * Tools must adjust the counts to convert them to Watts using
- * the duration of the measurement. Tools may use a function such as
- * ldexp(raw_count, -32);

+ * Support Intel/AMD RAPL energy consumption counters
+ * Copyright (C) 2013 Google, Inc., Stephane Eranian
+ *
+ * Intel RAPL interface is specified in the IA-32 Manual Vol3b
+ * section 14.7.1 (September 2013)
+ *
+ * AMD RAPL interface for Fam17h is described in the public PPR:
+ * https://bugzilla.kernel.org/show_bug.cgi?id=206537
+ *
+ * RAPL provides more controls than just reporting energy consumption
+ * however here we only expose the 3 energy consumption free running
+ * counters (pp0, pkg, dram).
+ *
+ * Each of those counters increments in a power unit defined by the
+ * RAPL_POWER_UNIT MSR. On SandyBridge, this unit is 1/(2^16) Joules
+ * but it can vary.
+ *
+ * Counter to rapl events mappings:
+ *
+ *  pp0 counter: consumption of all physical cores (power plane 0)
+ * 	  event: rapl_energy_cores
+ *    perf code: 0x1
+ *
+ *  pkg counter: consumption of the whole processor package
+ *	  event: rapl_energy_pkg
+ *    perf code: 0x2
+ *
+ * dram counter: consumption of the dram domain (servers only)
+ *	  event: rapl_energy_dram
+ *    perf code: 0x3
+ *
+ * gpu counter: consumption of the builtin-gpu domain (client only)
+ *	  event: rapl_energy_gpu
+ *    perf code: 0x4
+ *
+ *  psys counter: consumption of the builtin-psys domain (client only)
+ *	  event: rapl_energy_psys
+ *    perf code: 0x5
+ *
+ * We manage those counters as free running (read-only). They may be
+ * use simultaneously by other tools, such as turbostat.
+ *
+ * The events only support system-wide mode counting. There is no
+ * sampling support because it does not make sense and is not
+ * supported by the RAPL hardware.
+ *
+ * Because we want to avoid floating-point operations in the kernel,
+ * the events are all reported in fixed point arithmetic (32.32).
+ * Tools must adjust the counts to convert them to Watts using
+ * the duration of the measurement. Tools may use a function such as
+ * ldexp(raw_count, -32);
