Delay accounting
----------------
Tasks encounter delays in execution when they wait
for some kernel resource to become available e.g. a
runnable task may wait for a free CPU to run on.
The per-task delay accounting functionality measures
the delays experienced by a task while
a) waiting for a CPU (while being runnable)
b) completion of synchronous block I/O initiated by the task
c) swapping in pages
and makes these statistics available to userspace through
the taskstats interface.
Such delays provide feedback for setting a task's cpu priority,
io priority and rss limit values appropriately. Long delays for
important tasks could be a trigger for raising its corresponding priority.
The functionality, through its use of the taskstats interface, also provides
delay statistics aggregated for all tasks (or threads) belonging to a
thread group (corresponding to a traditional Unix process). This is a commonly
needed aggregation that is more efficiently done by the kernel.
Userspace utilities, particularly resource management applications, can also
aggregate delay statistics into arbitrary groups. To enable this, delay
statistics of a task are available both during its lifetime as well as on its
exit, ensuring continuous and complete monitoring can be done.
Interface
---------
Delay accounting uses the taskstats interface which is described
in detail in a separate document in this directory. Taskstats returns a
generic data structure to userspace corresponding to per-pid and per-tgid
statistics. The delay accounting functionality populates specific fields of
this structure. See
include/linux/taskstats.h
for a description of the fields pertaining to delay accounting.
It will generally be in the form of counters returning the cumulative
delay seen for cpu, sync block I/O, swapin etc.
Taking the difference of two successive readings of a given
counter (say cpu_delay_total) for a task will give the delay
experienced by the task waiting for the corresponding resource
in that interval.
When a task exits, records containing the per-task statistics
are sent to userspace without requiring a command. If it is the last exiting
task of a thread group, the per-tgid statistics are also sent. More details
are given in the taskstats interface description.
The getdelays.c userspace utility in this directory allows simple commands to
be run and the corresponding delay statistics to be displayed. It also serves
as an example of using the taskstats interface.
Usage
-----
Compile the kernel with
CONFIG_TASK_DELAY_ACCT=y
CONFIG_TASKSTATS=y
Enable the accounting at boot time by adding
the following to the kernel boot options
delayacct
and after the system has booted up, use a utility
similar to getdelays.c to access the delays
seen by a given task or a task group (tgid).
The utility also allows a given command to be
executed and the corresponding delays to be
seen.
General format of the getdelays command
getdelays [-t tgid] [-p pid] [-c cmd...]
Get delays, since system boot, for pid 10
# ./getdelays -p 10
(output similar to next case)
Get sum of delays, since system boot, for all pids with tgid 5
# ./getdelays -t 5
CPU count real total virtual total delay total
7876 92005750 100000000 24001500
IO count delay total

Get delays seen in executing a given simple command
# ./getdelays -c ls /

Per-task statistics interface
-----------------------------
Taskstats is a netlink-based interface for sending per-task and
per-process statistics from the kernel to userspace.
Taskstats was designed for the following benefits:
- efficiently provide statistics during lifetime of a task and on its exit
- unified interface for multiple accounting subsystems
- extensibility for use by future accounting patches
Terminology
-----------
"pid", "tid" and "task" are used interchangeably and refer to the standard
Linux task defined by struct task_struct. per-pid stats are the same as
per-task stats.
"tgid", "process" and "thread group" are used interchangeably and refer to the
tasks that share an mm_struct i.e. the traditional Unix process. Despite the
use of tgid, there is no special treatment for the task that is thread group
leader - a process is deemed alive as long as it has any task belonging to it.
Usage
-----
To get statistics during a task's lifetime, userspace opens a unicast netlink
socket (NETLINK_GENERIC family) and sends commands specifying a pid or a tgid.
The response contains statistics for a task (if pid is specified) or the sum of
statistics for all tasks of the process (if tgid is specified).
To obtain statistics for tasks which are exiting, the userspace listener
sends a register command and specifies a cpumask. Whenever a task exits on
one of the cpus in the cpumask, its per-pid statistics are sent to the
registered listener. Using cpumasks allows the data received by one listener
to be limited and assists in flow control over the netlink interface and is
explained in more detail below.
If the exiting task is the last thread exiting its thread group,
an additional record containing the per-tgid stats is also sent to userspace.
The latter contains the sum of per-pid stats for all threads in the thread
group, both past and present.
getdelays.c is a simple utility demonstrating usage of the taskstats interface
for reporting delay accounting statistics. Users can register cpumasks,
send commands and process responses, listen for per-tid/tgid exit data,
write the data received to a file and do basic flow control by increasing
receive buffer sizes.
Interface
---------
The user-kernel interface is encapsulated in include/linux/taskstats.h
To avoid this documentation becoming obsolete as the interface evolves, only
an outline of the current version is given. taskstats.h always overrides the
description here.
struct taskstats is the common accounting structure for both per-pid and
per-tgid data. It is versioned and can be extended by each accounting subsystem
that is added to the kernel. The fields and their semantics are defined in the
taskstats.h file.
The data exchanged between user and kernel space is a netlink message belonging
to the NETLINK_GENERIC family and using the netlink attributes interface.
The messages are in the format
+----------+- - -+-------------+-------------------+
| nlmsghdr | Pad | genlmsghdr | taskstats payload |
+----------+- - -+-------------+-------------------+
The taskstats payload is one of the following three kinds:
1. Commands: Sent from user to kernel. Commands to get data on
a pid/tgid consist of one attribute, of type TASKSTATS_CMD_ATTR_PID/TGID,
containing a u32 pid or tgid in the attribute payload. The pid/tgid denotes
the task/process for which userspace wants statistics.
Commands to register/deregister interest in exit data from a set of cpus
consist of one attribute, of type
TASKSTATS_CMD_ATTR_REGISTER/DEREGISTER_CPUMASK and contain a cpumask in the
attribute payload. The cpumask is specified as an ascii string of
comma-separated cpu ranges e.g. to listen to exit data from cpus 1,2,3,5,7,8
the cpumask would be "1-3,5,7-8". If userspace forgets to deregister interest
in cpus before closing the listening socket, the kernel cleans up its interest
set over time. However, for the sake of efficiency, an explicit deregistration
is advisable.
2. Response for a command: sent from the kernel in response to a userspace
command. The payload is a series of three attributes of type:
a) TASKSTATS_TYPE_AGGR_PID/TGID : attribute containing no payload but indicates
a pid/tgid will be followed by some stats.
b) TASKSTATS_TYPE_PID/TGID: attribute whose payload is the pid/tgid whose stats
is being returned.
c) TASKSTATS_TYPE_STATS: attribute with a struct taskstsats as payload. The
same structure is used for both per-pid and per-tgid stats.
3. New message sent by kernel whenever a task exits. The payload consists of a
series of attributes of the following type:
a) TASKSTATS_TYPE_AGGR_PID: indicates next two attributes will be pid+stats
b) TASKSTATS_TYPE_PID: contains exiting task's pid
c) TASKSTATS_TYPE_STATS: contains the exiting task's per-pid stats
d) TASKSTATS_TYPE_AGGR_TGID: indicates next two attributes will be tgid+stats
e) TASKSTATS_TYPE_TGID: contains tgid of process to which task belongs
f) TASKSTATS_TYPE_STATS: contains the per-tgid stats for exiting task's process
per-tgid stats
--------------
Taskstats provides per-process stats, in addition to per-task stats, since
resource management is often done at a process granularity and aggregating task
stats in userspace alone is inefficient and potentially inaccurate (due to lack
of atomicity).
However, maintaining per-process, in addition to per-task stats, within the
kernel has space and time overheads. To address this, the taskstats code
accumalates each exiting task's statistics into a process-wide data structure.
When the last task of a process exits, the process level data accumalated also
gets sent to userspace (along with the per-task data).
When a user queries to get per-tgid data, the sum of all other live threads in
the group is added up and added to the accumalated total for previously exited
threads of the same thread group.
Extending taskstats
-------------------
There are two ways to extend the taskstats interface to export more
per-task/process stats as patches to collect them get added to the kernel
in future:
1. Adding more fields to the end of the existing struct taskstats. Backward
compatibility is ensured by the version number within the
structure. Userspace will use only the fields of the struct that correspond
to the version its using.
2. Defining separate statistic structs and using the netlink attributes
interface to return them. Since userspace processes each netlink attribute
independently, it can always ignore attributes whose type it does not
understand (because it is using an older version of the interface).
Choosing between 1. and 2. is a matter of trading off flexibility and
overhead. If only a few fields need to be added, then 1. is the preferable
path since the kernel and userspace don't need to incur the overhead of
processing new netlink attributes. But if the new fields expand the existing
struct too much, requiring disparate userspace accounting utilities to
unnecessarily receive large structures whose fields are of no interest, then
extending the attributes structure would be worthwhile.
Flow control for taskstats
--------------------------
When the rate of task exits becomes large, a listener may not be able to keep
up with the kernel's rate of sending per-tid/tgid exit data leading to data
loss. This possibility gets compounded when the taskstats structure gets
extended and the number of cpus grows large.
To avoid losing statistics, userspace should do one or more of the following:
- increase the receive buffer sizes for the netlink sockets opened by
listeners to receive exit data.
- create more listeners and reduce the number of cpus being listened to by
each listener. In the extreme case, there could be one listener for each cpu.
Users may also consider setting the cpu affinity of the listener to the subset
of cpus to which it listens, especially if they are listening to just one cpu.
Despite these measures, if the userspace receives ENOBUFS error messages
indicated overflow of receive buffers, it should take measures to handle the
loss of data.

syslinux is to use the zdisk or bzdisk make targets which use
and bzimage images respectively. Both targets accept the
FDARGS parameter which can be used to set the kernel command line.

make bzdisk FDARGS="root=/dev/nfs"

access to the floppy drive device, /dev/fd0
For more information on syslinux, including how to create bootdisks
for prebuilt kernels, see http://syslinux.zytor.com/
N.B: Previously it was possible to write a kernel directly to
a floppy using dd, configure the boot device using rdev, and
boot using the resulting floppy. Linux no longer supports this
method of booting.
3.2) Booting from a cdrom using isolinux
When building kernels, an easy way to create a bootable cdrom that
uses isolinux is to use the isoimage target which uses a bzimage
image. Like zdisk and bzdisk, this target accepts the FDARGS
parameter which can be used to set the kernel command line.
e.g.
make isoimage FDARGS="root=/dev/nfs"
The resulting iso image will be arch/<ARCH>/boot/image.iso
This can be written to a cdrom using a variety of tools including
cdrecord.
e.g.
cdrecord dev=ATAPI:1,0,0 arch/i386/boot/image.iso
For more information on isolinux, including how to create bootdisks
for prebuilt kernels, see http://syslinux.zytor.com/
3.2) Using LILO
When using LILO all the necessary command line parameters may be
specified using the 'append=' directive in the LILO configuration
file.
However, to use the 'root=' directive you also need to create
a dummy root device, which may be removed after LILO is run.
mknod /dev/boot255 c 0 255
Then copy the kernel zImage file onto a floppy using dd:
dd if=/usr/src/linux/arch/i386/boot/zImage of=/dev/fd0
And finally use rdev to set the root device:
rdev /dev/fd0 /dev/boot255
You can then remove the dummy device /dev/boot255 again. There
is no real device available for it.
The other two kernel command line parameters cannot be substi-
tuted with rdev. Therefore, using this method the kernel will
by default use RARP and/or BOOTP, and if it gets an answer via
RARP will mount the directory /tftpboot/<client-ip>/ as its
root. If it got a BOOTP answer the directory name in that answer
is used.
3.2) Using LILO
When using LILO you can specify all necessary command line
parameters with the 'append=' command in the LILO configuration
file. However, to use the 'root=' command you also need to
set up a dummy device as described in 3.1 above. For how to use
LILO and its 'append=' command please refer to the LILO
documentation.
For information on configuring LILO, please refer to its documentation.
3.3) Using GRUB
When you use GRUB, you simply append the parameters after the kernel
specification: "kernel <kernel> <parameters>" (without the quotes).
When using GRUB, kernel parameter are simply appended after the kernel
specification: kernel <kernel> <parameters>
3.4) Using loadlin
When you want to boot Linux from a DOS command prompt without
having a local hard disk to mount as root, you can use loadlin.
I was told that it works, but haven't used it myself yet. In
general you should be able to create a kernel command line simi-
lar to how LILO is doing it. Please refer to the loadlin docu-
mentation for further information.
loadlin may be used to boot Linux from a DOS command prompt without
requiring a local hard disk to mount as root. This has not been
thoroughly tested by the authors of this document, but in general
it should be possible configure the kernel command line similarly
to the configuration of LILO.
Please refer to the loadlin documentation for further information.
3.5) Using a boot ROM
This is probably the most elegant way of booting a diskless
client. With a boot ROM the kernel gets loaded using the TFTP
protocol. As far as I know, no commercial boot ROMs yet
support booting Linux over the network, but there are two
free implementations of a boot ROM available on sunsite.unc.edu
and its mirrors. They are called 'netboot-nfs' and 'etherboot'.
Both contain everything you need to boot a diskless Linux client.
This is probably the most elegant way of booting a diskless client.
With a boot ROM the kernel is loaded using the TFTP protocol. The
authors of this document are not aware of any no commercial boot

are two free implementations of a boot ROM, netboot-nfs and
etherboot, both of which are available on sunsite.unc.edu, and both
of which contain everything you need to boot a diskless Linux client.
3.6) Using pxelinux
Using pxelinux you specify the kernel you built with
Pxelinux may be used to boot linux using the PXE boot loader
which is present on many modern network cards.
When using pxelinux, the kernel image is specified using
"kernel <relative-path-below /tftpboot>". The nfsroot parameters
are passed to the kernel by adding them to the "append" line.
You may perhaps also want to fine tune the console output,
see Documentation/serial-console.txt for serial console help.
It is common to use serial console in conjunction with pxeliunx,
see Documentation/serial-console.txt for more information.
For more information on isolinux, including how to create bootdisks
for prebuilt kernels, see http://syslinux.zytor.com/
