- depends on HOTPLUG_CPU && NOTIFIER_ERROR_INJECTION
- help
- This option provides a kernel module that can be used to test
- the error handling of the cpu notifiers by injecting artificial
- errors to CPU notifier chain callbacks. It is controlled through
- debugfs interface under /sys/kernel/debug/notifier-error-inject/cpu
-
- If the notifier call chain should be failed with some events
- notified, write the error code to "actions/<notifier event>/error".
-
- Example: Inject CPU offline error (-1 == -EPERM)
-
- # cd /sys/kernel/debug/notifier-error-inject/cpu
- # echo -1 > actions/CPU_DOWN_PREPARE/error
- # echo 0 > /sys/devices/system/cpu/cpu1/online
- bash: echo: write error: Operation not permitted
-
- To compile this code as a module, choose M here: the module will
- be called cpu-notifier-error-inject.
-
- If unsure, say N.

.SS Options
Options can be specified with a single or double '-', and only as much of the option
name as necessary to disambiguate it from others is necessary. Note that options are case-sensitive.
-\fB--Counter MSR#\fP shows the delta of the specified 64-bit MSR counter.
.PP
-\fB--counter MSR#\fP shows the delta of the specified 32-bit MSR counter.
+\fB--add attributes\fP add column with counter having specified 'attributes'. The 'location' attribute is required, all others are optional.
+.nf
+ location: {\fBmsrDDD\fP | \fBmsr0xXXX\fP}
+ msrDDD is a decimal offset, eg. msr16
+ msr0xXXX is a hex offset, eg. msr0x10
+
+ scope: {\fBcpu\fP | \fBcore\fP | \fBpackage\fP}
+ sample and print the counter for every cpu, core, or package.
+ default: cpu
+
+ size: {\fBu32\fP | \fBu64\fP }
+ MSRs are read as 64-bits, u32 truncates the displayed value to 32-bits.
+ default: u64
+
+ format: {\fBraw\fP | \fBdelta\fP | \fBpercent\fP}
+ 'raw' shows the MSR contents in hex.
+ 'delta' shows the difference in values during the measurement interval.
+ 'percent' shows the delta as a percentage of the cycles elapsed.
+ default: delta
+.fi
.PP
\fB--Dump\fP displays the raw counter values.
.PP
.PP
\fB--Joules\fP displays energy in Joules, rather than dividing Joules by time to print power in Watts.
.PP
-\fB--MSR MSR#\fP shows the specified 64-bit MSR value.
-.PP
-\fB--msr MSR#\fP shows the specified 32-bit MSR value.
-.PP
\fB--Package\fP limits output to the system summary plus the 1st thread in each Package.
.PP
\fB--processor\fP limits output to the system summary plus the 1st thread in each processor of each package. Ie. it skips hyper-threaded siblings.
