CONFIG_RCU_TRACE debugfs Files and Formats
|
||||
|
||||
|
||||
The rcupreempt and rcutree implementations of RCU provide debugfs trace
|
||||
output that summarizes counters and state. This information is useful for
|
||||
debugging RCU itself, and can sometimes also help to debug abuses of RCU.
|
||||
Note that the rcuclassic implementation of RCU does not provide debugfs
|
||||
trace output.
|
||||
|
||||
The following sections describe the debugfs files and formats for
|
||||
preemptable RCU (rcupreempt) and hierarchical RCU (rcutree).
|
||||
|
||||
|
||||
Preemptable RCU debugfs Files and Formats
|
||||
|
||||
This implementation of RCU provides three debugfs files under the
|
||||
top-level directory RCU: rcu/rcuctrs (which displays the per-CPU
|
||||
counters used by preemptable RCU) rcu/rcugp (which displays grace-period
|
||||
counters), and rcu/rcustats (which internal counters for debugging RCU).
|
||||
|
||||
The output of "cat rcu/rcuctrs" looks as follows:
|
||||
|
||||
CPU last cur F M
|
||||
0 5 -5 0 0
|
||||
1 -1 0 0 0
|
||||
2 0 1 0 0
|
||||
3 0 1 0 0
|
||||
4 0 1 0 0
|
||||
5 0 1 0 0
|
||||
6 0 2 0 0
|
||||
7 0 -1 0 0
|
||||
8 0 1 0 0
|
||||
ggp = 26226, state = waitzero
|
||||
|
||||
The per-CPU fields are as follows:
|
||||
|
||||
o "CPU" gives the CPU number. Offline CPUs are not displayed.
|
||||
|
||||
o "last" gives the value of the counter that is being decremented
|
||||
for the current grace period phase. In the example above,
|
||||
the counters sum to 4, indicating that there are still four
|
||||
RCU read-side critical sections still running that started
|
||||
before the last counter flip.
|
||||
|
||||
o "cur" gives the value of the counter that is currently being
|
||||
both incremented (by rcu_read_lock()) and decremented (by
|
||||
rcu_read_unlock()). In the example above, the counters sum to
|
||||
1, indicating that there is only one RCU read-side critical section
|
||||
still running that started after the last counter flip.
|
||||
|
||||
o "F" indicates whether RCU is waiting for this CPU to acknowledge
|
||||
a counter flip. In the above example, RCU is not waiting on any,
|
||||
which is consistent with the state being "waitzero" rather than
|
||||
"waitack".
|
||||
|
||||
o "M" indicates whether RCU is waiting for this CPU to execute a
|
||||
memory barrier. In the above example, RCU is not waiting on any,
|
||||
which is consistent with the state being "waitzero" rather than
|
||||
"waitmb".
|
||||
|
||||
o "ggp" is the global grace-period counter.
|
||||
|
||||
o "state" is the RCU state, which can be one of the following:
|
||||
|
||||
o "idle": there is no grace period in progress.
|
||||
|
||||
o "waitack": RCU just incremented the global grace-period
|
||||
counter, which has the effect of reversing the roles of
|
||||
the "last" and "cur" counters above, and is waiting for
|
||||
all the CPUs to acknowledge the flip. Once the flip has
|
||||
been acknowledged, CPUs will no longer be incrementing
|
||||
what are now the "last" counters, so that their sum will
|
||||
decrease monotonically down to zero.
|
||||
|
||||
o "waitzero": RCU is waiting for the sum of the "last" counters
|
||||
to decrease to zero.
|
||||
|
||||
o "waitmb": RCU is waiting for each CPU to execute a memory
|
||||
barrier, which ensures that instructions from a given CPU's
|
||||
last RCU read-side critical section cannot be reordered
|
||||
with instructions following the memory-barrier instruction.
|
||||
|
||||
The output of "cat rcu/rcugp" looks as follows:
|
||||
|
||||
oldggp=48870 newggp=48873
|
||||
|
||||
Note that reading from this file provokes a synchronize_rcu(). The
|
||||
"oldggp" value is that of "ggp" from rcu/rcuctrs above, taken before
|
||||
executing the synchronize_rcu(), and the "newggp" value is also the
|
||||
"ggp" value, but taken after the synchronize_rcu() command returns.
|
||||
|
||||
|
||||
The output of "cat rcu/rcugp" looks as follows:
|
||||
|
||||
na=1337955 nl=40 wa=1337915 wl=44 da=1337871 dl=0 dr=1337871 di=1337871
|
||||
1=50989 e1=6138 i1=49722 ie1=82 g1=49640 a1=315203 ae1=265563 a2=49640
|
||||
z1=1401244 ze1=1351605 z2=49639 m1=5661253 me1=5611614 m2=49639
|
||||
|
||||
These are counters tracking internal preemptable-RCU events, however,
|
||||
some of them may be useful for debugging algorithms using RCU. In
|
||||
particular, the "nl", "wl", and "dl" values track the number of RCU
|
||||
callbacks in various states. The fields are as follows:
|
||||
|
||||
o "na" is the total number of RCU callbacks that have been enqueued
|
||||
since boot.
|
||||
|
||||
o "nl" is the number of RCU callbacks waiting for the previous
|
||||
grace period to end so that they can start waiting on the next
|
||||
grace period.
|
||||
|
||||
o "wa" is the total number of RCU callbacks that have started waiting
|
||||
for a grace period since boot. "na" should be roughly equal to
|
||||
"nl" plus "wa".
|
||||
|
||||
o "wl" is the number of RCU callbacks currently waiting for their
|
||||
grace period to end.
|
||||
|
||||
o "da" is the total number of RCU callbacks whose grace periods
|
||||
have completed since boot. "wa" should be roughly equal to
|
||||
"wl" plus "da".
|
||||
|
||||
o "dr" is the total number of RCU callbacks that have been removed
|
||||
from the list of callbacks ready to invoke. "dr" should be roughly
|
||||
equal to "da".
|
||||
|
||||
o "di" is the total number of RCU callbacks that have been invoked
|
||||
since boot. "di" should be roughly equal to "da", though some
|
||||
early versions of preemptable RCU had a bug so that only the
|
||||
last CPU's count of invocations was displayed, rather than the
|
||||
sum of all CPU's counts.
|
||||
|
||||
o "1" is the number of calls to rcu_try_flip(). This should be
|
||||
roughly equal to the sum of "e1", "i1", "a1", "z1", and "m1"
|
||||
described below. In other words, the number of times that
|
||||
the state machine is visited should be equal to the sum of the
|
||||
number of times that each state is visited plus the number of
|
||||
times that the state-machine lock acquisition failed.
|
||||
|
||||
o "e1" is the number of times that rcu_try_flip() was unable to
|
||||
acquire the fliplock.
|
||||
|
||||
o "i1" is the number of calls to rcu_try_flip_idle().
|
||||
|
||||
o "ie1" is the number of times rcu_try_flip_idle() exited early
|
||||
due to the calling CPU having no work for RCU.
|
||||
|
||||
o "g1" is the number of times that rcu_try_flip_idle() decided
|
||||
to start a new grace period. "i1" should be roughly equal to
|
||||
"ie1" plus "g1".
|
||||
|
||||
o "a1" is the number of calls to rcu_try_flip_waitack().
|
||||
|
||||
o "ae1" is the number of times that rcu_try_flip_waitack() found
|
||||
that at least one CPU had not yet acknowledge the new grace period
|
||||
(AKA "counter flip").
|
||||
|
||||
o "a2" is the number of time rcu_try_flip_waitack() found that
|
||||
all CPUs had acknowledged. "a1" should be roughly equal to
|
||||
"ae1" plus "a2". (This particular output was collected on
|
||||
a 128-CPU machine, hence the smaller-than-usual fraction of
|
||||
calls to rcu_try_flip_waitack() finding all CPUs having already
|
||||
acknowledged.)
|
||||
|
||||
o "z1" is the number of calls to rcu_try_flip_waitzero().
|
||||
|
||||
o "ze1" is the number of times that rcu_try_flip_waitzero() found
|
||||
that not all of the old RCU read-side critical sections had
|
||||
completed.
|
||||
|
||||
o "z2" is the number of times that rcu_try_flip_waitzero() finds
|
||||
the sum of the counters equal to zero, in other words, that
|
||||
all of the old RCU read-side critical sections had completed.
|
||||
The value of "z1" should be roughly equal to "ze1" plus
|
||||
"z2".
|
||||
|
||||
o "m1" is the number of calls to rcu_try_flip_waitmb().
|
||||
|
||||
o "me1" is the number of times that rcu_try_flip_waitmb() finds
|
||||
that at least one CPU has not yet executed a memory barrier.
|
||||
|
||||
o "m2" is the number of times that rcu_try_flip_waitmb() finds that
|
||||
all CPUs have executed a memory barrier.

The rcutree implementation of RCU provides debugfs trace output that
|
||||
summarizes counters and state. This information is useful for debugging

RCU itself, and can sometimes also help to debug abuses of RCU.

What: USER_SCHED
|
||||
When: 2.6.34
|
||||
|
||||
Why: USER_SCHED was implemented as a proof of concept for group scheduling.
|
||||
The effect of USER_SCHED can already be achieved from userspace with
|
||||
the help of libcgroup. The removal of USER_SCHED will also simplify
|
||||
the scheduler code with the removal of one major ifdef. There are also
|
||||
issues USER_SCHED has with USER_NS. A decision was taken not to fix
|
||||
those and instead remove USER_SCHED. Also new group scheduling
|
||||
features will not be implemented for USER_SCHED.

Kprobe-based Event Tracing
|
||||
==========================
|
||||
|
||||
Documentation is written by Masami Hiramatsu
|
||||
|
||||
|
||||
Overview
|
||||
--------
|
||||
These events are similar to tracepoint based events. Instead of Tracepoint,
|
||||
this is based on kprobes (kprobe and kretprobe). So it can probe wherever
|
||||
kprobes can probe (this means, all functions body except for __kprobes
|
||||
functions). Unlike the Tracepoint based event, this can be added and removed
|
||||
dynamically, on the fly.
|
||||
|
||||
To enable this feature, build your kernel with CONFIG_KPROBE_TRACING=y.
|
||||
|
||||
Similar to the events tracer, this doesn't need to be activated via
|
||||
current_tracer. Instead of that, add probe points via
|
||||
/sys/kernel/debug/tracing/kprobe_events, and enable it via
|
||||
/sys/kernel/debug/tracing/events/kprobes/<EVENT>/enabled.
|
||||
|
||||
|
||||
Synopsis of kprobe_events
|
||||
-------------------------
|
||||
p[:[GRP/]EVENT] SYMBOL[+offs]|MEMADDR [FETCHARGS] : Set a probe
|
||||
r[:[GRP/]EVENT] SYMBOL[+0] [FETCHARGS] : Set a return probe
|
||||
|
||||
GRP : Group name. If omitted, use "kprobes" for it.
|
||||
EVENT : Event name. If omitted, the event name is generated
|
||||
based on SYMBOL+offs or MEMADDR.
|
||||
SYMBOL[+offs] : Symbol+offset where the probe is inserted.
|
||||
MEMADDR : Address where the probe is inserted.
|
||||
|
||||
FETCHARGS : Arguments. Each probe can have up to 128 args.
|
||||
%REG : Fetch register REG
|
||||
@ADDR : Fetch memory at ADDR (ADDR should be in kernel)
|
||||
@SYM[+|-offs] : Fetch memory at SYM +|- offs (SYM should be a data symbol)
|
||||
$stackN : Fetch Nth entry of stack (N >= 0)
|
||||
$stack : Fetch stack address.
|
||||
$argN : Fetch function argument. (N >= 0)(*)
|
||||
$retval : Fetch return value.(**)
|
||||
+|-offs(FETCHARG) : Fetch memory at FETCHARG +|- offs address.(***)
|
||||
NAME=FETCHARG: Set NAME as the argument name of FETCHARG.
|
||||
|
||||
(*) aN may not correct on asmlinkaged functions and at the middle of
|
||||
function body.
|
||||
(**) only for return probe.
|
||||
(***) this is useful for fetching a field of data structures.
|
||||
|
||||
|
||||
Per-Probe Event Filtering
|
||||
-------------------------
|
||||
Per-probe event filtering feature allows you to set different filter on each
|
||||
probe and gives you what arguments will be shown in trace buffer. If an event
|
||||
name is specified right after 'p:' or 'r:' in kprobe_events, it adds an event
|
||||
under tracing/events/kprobes/<EVENT>, at the directory you can see 'id',
|
||||
'enabled', 'format' and 'filter'.
|
||||
|
||||
enabled:
|
||||
You can enable/disable the probe by writing 1 or 0 on it.
|
||||
|
||||
format:
|
||||
This shows the format of this probe event.
|
||||
|
||||
filter:
|
||||
You can write filtering rules of this event.
|
||||
|
||||
id:
|
||||
This shows the id of this probe event.
|
||||
|
||||
|
||||
Event Profiling
|
||||
---------------
|
||||
You can check the total number of probe hits and probe miss-hits via
|
||||
/sys/kernel/debug/tracing/kprobe_profile.
|
||||
The first column is event name, the second is the number of probe hits,
|
||||
the third is the number of probe miss-hits.
|
||||
|
||||
|
||||
Usage examples
|
||||
--------------
|
||||
To add a probe as a new event, write a new definition to kprobe_events
|
||||
as below.
|
||||
|
||||
echo p:myprobe do_sys_open dfd=$arg0 filename=$arg1 flags=$arg2 mode=$arg3 > /sys/kernel/debug/tracing/kprobe_events
|
||||
|
||||
This sets a kprobe on the top of do_sys_open() function with recording
|
||||
1st to 4th arguments as "myprobe" event. As this example shows, users can
|
||||
choose more familiar names for each arguments.
|
||||
|
||||
echo r:myretprobe do_sys_open $retval >> /sys/kernel/debug/tracing/kprobe_events
|
||||
|
||||
This sets a kretprobe on the return point of do_sys_open() function with
|
||||
recording return value as "myretprobe" event.
|
||||
You can see the format of these events via
|
||||
/sys/kernel/debug/tracing/events/kprobes/<EVENT>/format.
|
||||
|
||||
cat /sys/kernel/debug/tracing/events/kprobes/myprobe/format
|
||||
name: myprobe
|
||||
ID: 75
|
||||
format:
|
||||
field:unsigned short common_type; offset:0; size:2;
|
||||
field:unsigned char common_flags; offset:2; size:1;
|
||||
field:unsigned char common_preempt_count; offset:3; size:1;
|
||||
field:int common_pid; offset:4; size:4;
|
||||
field:int common_tgid; offset:8; size:4;
|
||||
|
||||
field: unsigned long ip; offset:16;tsize:8;
|
||||
field: int nargs; offset:24;tsize:4;
|
||||
field: unsigned long dfd; offset:32;tsize:8;
|
||||
field: unsigned long filename; offset:40;tsize:8;
|
||||
field: unsigned long flags; offset:48;tsize:8;
|
||||
field: unsigned long mode; offset:56;tsize:8;
|
||||
|
||||
print fmt: "(%lx) dfd=%lx filename=%lx flags=%lx mode=%lx", REC->ip, REC->dfd, REC->filename, REC->flags, REC->mode
|
||||
|
||||
|
||||
You can see that the event has 4 arguments as in the expressions you specified.
|
||||
|
||||
echo > /sys/kernel/debug/tracing/kprobe_events
|
||||
|
||||
This clears all probe points.
|
||||
|
||||
Right after definition, each event is disabled by default. For tracing these
|
||||
events, you need to enable it.
|
||||
|
||||
echo 1 > /sys/kernel/debug/tracing/events/kprobes/myprobe/enable
|
||||
echo 1 > /sys/kernel/debug/tracing/events/kprobes/myretprobe/enable
|
||||
|
||||
And you can see the traced information via /sys/kernel/debug/tracing/trace.
|
||||
|
||||

returns from SYMBOL(e.g. "sys_open+0x1b/0x1d <- do_sys_open" means kernel
|
