opcontrol: usage:
-l/--list-events list event types and unit masks
-?/--help this message
-v/--version show version
--init loads the oprofile module and oprofilefs
--setup give setup arguments (may be omitted)
--status show configuration
--start-daemon start daemon without starting profiling
-s/--start start data collection
-d/--dump flush the collected profiling data
-t/--stop stop data collection
-h/--shutdown stop data collection and kill daemon
-V/--verbose[=all,sfile,arcs,samples,module,misc,ext]
be verbose in the daemon log
--reset clears out data from current session
--save=name save data from current session to session_name
--deinit unload the oprofile module and oprofilefs
-e/--event=eventspec
Choose an event. May be specified multiple times. Of the form
"default" or "name:count:unitmask:kernel:user", where :
name: event name, e.g. CPU_CLK_UNHALTED or RTC_INTERRUPTS
count: reset counter value e.g. 100000
unitmask: hardware unit mask e.g. 0x0f
kernel: whether to profile kernel: 0 or 1
user: whether to profile userspace: 0 or 1
-p/--separate=type,[types]
Separate profiles as follows :
none: no profile separation
library: separate shared library profiles per-application
kernel: same as library, plus kernel profiles
thread: per-thread/process profiles
cpu: per CPU profiles
all: all of the above
-c/--callgraph=#depth enable callgraph sample collection with a
maximum depth. Use '0' to disable callgraph
profiling.
--session-dir=dir place sample database in dir instead of
default location (/var/lib/oprofile)
-i/--image=name[,names] list of binaries to profile (default is "all")
--vmlinux=file vmlinux kernel image
--no-vmlinux no kernel image (vmlinux) available
--kernel-range=start,end kernel range vma address in hexadecimal
--buffer-size=num kernel buffer size in sample units.
Rules: A non-zero value goes into effect after
a '--shutdown/start' sequence. A value of
zero sets this parameter back to default value
but does not go into effect until after a
'--deinit/init' sequence.
--buffer-watershed kernel buffer watershed in sample units (2.6
kernel). Same rules as defined for
buffer-size.
--cpu-buffer-size=num per-cpu buffer size in units (2.6 kernel)
Same rules as defined for buffer-size.
--xen Xen image (for Xen only)
--active-domains=<list> List of domains in profiling session (for Xen)
(list contains domain ids separated by commas)
System z specific options
--s390hwsampbufsize=num Number of 2MB areas used per CPU for storing sample data.
