    OPERANDS is the list of operands.

-/*
- * Extended scheduling parameters data structure.
- *
- * This is needed because the original struct sched_param can not be
- * altered without introducing ABI issues with legacy applications
- * (e.g., in sched_getparam()).
- *
- * However, the possibility of specifying more than just a priority for
- * the tasks may be useful for a wide variety of application fields, e.g.,
- * multimedia, streaming, automation and control, and many others.
- *
- * This variant (sched_attr) is meant at describing a so-called
- * sporadic time-constrained task. In such model a task is specified by:
- *  - the activation period or minimum instance inter-arrival time;
- *  - the maximum (or average, depending on the actual scheduling
- *    discipline) computation time of all instances, a.k.a. runtime;
- *  - the deadline (relative to the actual activation time) of each
- *    instance.
- * Very briefly, a periodic (sporadic) task asks for the execution of
- * some specific computation --which is typically called an instance--
- * (at most) every period. Moreover, each instance typically lasts no more
- * than the runtime and must be completed by time instant t equal to
- * the instance activation time + the deadline.
- *
- * This is reflected by the actual fields of the sched_attr structure:
- *
- *  @size		size of the structure, for fwd/bwd compat.
- *
- *  @sched_policy	task's scheduling policy
- *  @sched_flags	for customizing the scheduler behaviour
- *  @sched_nice		task's nice value      (SCHED_NORMAL/BATCH)
- *  @sched_priority	task's static priority (SCHED_FIFO/RR)
- *  @sched_deadline	representative of the task's deadline
- *  @sched_runtime	representative of the task's runtime
- *  @sched_period	representative of the task's period
- *
- * Given this task model, there are a multiplicity of scheduling algorithms
- * and policies, that can be used to ensure all the tasks will make their
- * timing constraints.
- *
- * As of now, the SCHED_DEADLINE policy (sched_dl scheduling class) is the
- * only user of this new interface. More information about the algorithm
- * available in the scheduling class file or in Documentation/.

+ * This variant (sched_attr) is meant at describing a so-called
+ * sporadic time-constrained task. In such model a task is specified by:
+ *  - the activation period or minimum instance inter-arrival time;
+ *  - the maximum (or average, depending on the actual scheduling
+ *    discipline) computation time of all instances, a.k.a. runtime;
+ *  - the deadline (relative to the actual activation time) of each
+ *    instance.
+ * Very briefly, a periodic (sporadic) task asks for the execution of
+ * some specific computation --which is typically called an instance--
+ * (at most) every period. Moreover, each instance typically lasts no more
+ * than the runtime and must be completed by time instant t equal to
+ * the instance activation time + the deadline.
+ *
+ * This is reflected by the actual fields of the sched_attr structure:
+ *
+ *  @size		size of the structure, for fwd/bwd compat.
+ *
+ *  @sched_policy	task's scheduling policy
+ *  @sched_flags	for customizing the scheduler behaviour
+ *  @sched_nice		task's nice value      (SCHED_NORMAL/BATCH)
+ *  @sched_priority	task's static priority (SCHED_FIFO/RR)
+ *  @sched_deadline	representative of the task's deadline
+ *  @sched_runtime	representative of the task's runtime
+ *  @sched_period	representative of the task's period
+ *
+ * Given this task model, there are a multiplicity of scheduling algorithms
+ * and policies, that can be used to ensure all the tasks will make their
+ * timing constraints.
+ *
+ * As of now, the SCHED_DEADLINE policy (sched_dl scheduling class) is the
+ * only user of this new interface. More information about the algorithm
+ * available in the scheduling class file or in Documentation/.

-.SH DEFAULT FIELD DESCRIPTIONS
+.SH ROW DESCRIPTIONS
+The system configuration dump (if --quiet is not used) is followed by statistics.  The first row of the statistics labels the content of each column (below).  The second row of statistics is the system summary line.  The system summary line has a '-' in the columns for the Package, Core, and CPU.  The contents of the system summary line depends on the type of column.  Columns that count items (eg. IRQ) show the sum across all CPUs in the system.  Columns that show a percentage show the average across all CPUs in the system.  Columns that dump raw MSR values simply show 0 in the summary.  After the system summary row, each row describes a specific Package/Core/CPU.  Note that if the --cpu parameter is used to limit which specific CPUs are displayed, turbostat will still collect statistics for all CPUs in the system and will still show the system summary for all CPUs in the system.

+.SH TOO MUCH INFORMATION EXAMPLE
+By default, turbostat dumps all possible information -- a system configuration header, followed by columns for all counters.
+This is ideal for remote debugging, use the "--out" option to save everything to a text file, and get that file to the expert helping you debug.
 .PP
-.SH PERIODIC EXAMPLE
-Without any parameters, turbostat displays statistics ever 5 seconds.
-Periodic output goes to stdout, by default, unless --out is used to specify an output file.
-The 5-second interval can be changed with th "-i sec" option.
-Or a command may be specified as in "FORK EXAMPLE" below.
+When you are not interested in all that information, and there are several ways to see only what you want.  First the "--quiet" option will skip the configuration information, and turbostat will show only the counter columns.  Second, you can reduce the columns with the "--hide" and "--show" options.  If you use the "--show" option, then turbostat will show only the columns you list.  If you use the "--hide" option, turbostat will show all columns, except the ones you list.
+.PP
+To find out what columns are available for --show and --hide, the "--list" option is available.  For convenience, the special strings "sysfs" can be used to refer to all of the sysfs C-state counters at once:

+.SH ONE SHOT COMMAND EXAMPLE
+If turbostat is invoked with a command, it will fork that command
+and output the statistics gathered after the command exits.
+In this case, turbostat output goes to stderr, by default.
+Output can instead be saved to a file using the --out option.
+In this example, the "sleep 10" command is forked, and turbostat waits for it to complete before saving all statistics into "ts.out".  Note that "sleep 10" is not part of turbostat, but is simply an example of a command that turbostat can fork.  The "ts.out" file is what you want to edit in a very wide window, paste into a spreadsheet, or attach to a bugzilla entry.

-.SH DEBUG EXAMPLE
-The "--debug" option prints additional system information before measurements:
+This example also shows the use of the --hide option to skip columns that are not wanted.
+Note that cpu4 in this example is 99.99% busy, while the other CPUs are all under 1% busy.
+Notice that cpu4's HT sibling is cpu0, which is under 1% busy, but can get into CPU%c1 only,
+because its cpu4's activity on shared hardware keeps it from entering a deeper C-state.
 
-The first row of statistics is a summary for the entire system.
-For residency % columns, the summary is a weighted average.
-For Temperature columns, the summary is the column maximum.
-For Watts columns, the summary is a system total.
-Subsequent rows show per-CPU statistics.
+.SH SYSTEM CONFIGURATION INFORMATION EXAMPLE
+
+By default, turbostat always dumps system configuration information
+before taking measurements.  In the example above, "--quiet" is used
+to suppress that output.  Here is an example of the configuration information:

-The --debug option adds additional columns to the measurement ouput, including CPU idle power-state residency processor temperature sensor readinds.
-See the field definitions above.
-.SH FORK EXAMPLE
-If turbostat is invoked with a command, it will fork that command
-and output the statistics gathered after the command exits.
-In this case, turbostat output goes to stderr, by default.
-Output can instead be saved to a file using the --out option.

+Here we limit turbostat to showing just the CPU number for cpu0 - cpu3.
+We add a counter showing the 32-bit raw value of MSR 0x199 (MSR_IA32_PERF_CTL),
+labeling it with the column header, "PRF_CTRL", and display it only once,
