REDUCING OS JITTER DUE TO PER-CPU KTHREADS
|
||||
|
||||
This document lists per-CPU kthreads in the Linux kernel and presents
|
||||
options to control their OS jitter. Note that non-per-CPU kthreads are
|
||||
not listed here. To reduce OS jitter from non-per-CPU kthreads, bind
|
||||
them to a "housekeeping" CPU dedicated to such work.

KTHREADS
|
||||
|
||||
Name: ehca_comp/%u
|
||||
Purpose: Periodically process Infiniband-related work.
|
||||
To reduce its OS jitter, do any of the following:
|
||||
1. Don't use eHCA Infiniband hardware, instead choosing hardware
|
||||
that does not require per-CPU kthreads. This will prevent these
|
||||
kthreads from being created in the first place. (This will
|
||||
work for most people, as this hardware, though important, is
|
||||
relatively old and is produced in relatively low unit volumes.)
|
||||
2. Do all eHCA-Infiniband-related work on other CPUs, including
|
||||
interrupts.
|
||||
3. Rework the eHCA driver so that its per-CPU kthreads are
|
||||
provisioned only on selected CPUs.
|
||||
|
||||
|
||||
Name: irq/%d-%s
|
||||
Purpose: Handle threaded interrupts.
|
||||
To reduce its OS jitter, do the following:
|
||||
1. Use irq affinity to force the irq threads to execute on
|
||||
some other CPU.
|
||||
|
||||
Name: kcmtpd_ctr_%d
|
||||
Purpose: Handle Bluetooth work.
|
||||
To reduce its OS jitter, do one of the following:
|
||||
1. Don't use Bluetooth, in which case these kthreads won't be
|
||||
created in the first place.
|
||||
2. Use irq affinity to force Bluetooth-related interrupts to
|
||||
occur on some other CPU and furthermore initiate all
|
||||
Bluetooth activity on some other CPU.
|
||||
|
||||
Name: ksoftirqd/%u
|
||||
Purpose: Execute softirq handlers when threaded or when under heavy load.
|
||||
To reduce its OS jitter, each softirq vector must be handled
|
||||
separately as follows:
|
||||
TIMER_SOFTIRQ: Do all of the following:
|
||||
1. To the extent possible, keep the CPU out of the kernel when it
|
||||
is non-idle, for example, by avoiding system calls and by forcing
|
||||
both kernel threads and interrupts to execute elsewhere.
|
||||
2. Build with CONFIG_HOTPLUG_CPU=y. After boot completes, force
|
||||
the CPU offline, then bring it back online. This forces
|
||||
recurring timers to migrate elsewhere. If you are concerned
|
||||
with multiple CPUs, force them all offline before bringing the
|
||||
first one back online. Once you have onlined the CPUs in question,
|
||||
do not offline any other CPUs, because doing so could force the
|
||||
timer back onto one of the CPUs in question.
|
||||
NET_TX_SOFTIRQ and NET_RX_SOFTIRQ: Do all of the following:
|
||||
1. Force networking interrupts onto other CPUs.
|
||||
2. Initiate any network I/O on other CPUs.
|
||||
3. Once your application has started, prevent CPU-hotplug operations
|
||||
from being initiated from tasks that might run on the CPU to
|
||||
be de-jittered. (It is OK to force this CPU offline and then
|
||||
bring it back online before you start your application.)
|
||||
BLOCK_SOFTIRQ: Do all of the following:
|
||||
1. Force block-device interrupts onto some other CPU.
|
||||
2. Initiate any block I/O on other CPUs.
|
||||
3. Once your application has started, prevent CPU-hotplug operations
|
||||
from being initiated from tasks that might run on the CPU to
|
||||
be de-jittered. (It is OK to force this CPU offline and then
|
||||
bring it back online before you start your application.)
|
||||
BLOCK_IOPOLL_SOFTIRQ: Do all of the following:
|
||||
1. Force block-device interrupts onto some other CPU.
|
||||
2. Initiate any block I/O and block-I/O polling on other CPUs.
|
||||
3. Once your application has started, prevent CPU-hotplug operations
|
||||
from being initiated from tasks that might run on the CPU to
|
||||
be de-jittered. (It is OK to force this CPU offline and then
|
||||
bring it back online before you start your application.)
|
||||
TASKLET_SOFTIRQ: Do one or more of the following:
|
||||
1. Avoid use of drivers that use tasklets. (Such drivers will contain
|
||||
calls to things like tasklet_schedule().)
|
||||
2. Convert all drivers that you must use from tasklets to workqueues.
|
||||
3. Force interrupts for drivers using tasklets onto other CPUs,
|
||||
and also do I/O involving these drivers on other CPUs.
|
||||
SCHED_SOFTIRQ: Do all of the following:
|
||||
1. Avoid sending scheduler IPIs to the CPU to be de-jittered,
|
||||
for example, ensure that at most one runnable kthread is present
|
||||
on that CPU. If a thread that expects to run on the de-jittered
|
||||
CPU awakens, the scheduler will send an IPI that can result in
|
||||
a subsequent SCHED_SOFTIRQ.
|
||||
2. Build with CONFIG_RCU_NOCB_CPU=y, CONFIG_RCU_NOCB_CPU_ALL=y,
|
||||
CONFIG_NO_HZ_FULL=y, and, in addition, ensure that the CPU
|
||||
to be de-jittered is marked as an adaptive-ticks CPU using the
|
||||
"nohz_full=" boot parameter. This reduces the number of
|
||||
scheduler-clock interrupts that the de-jittered CPU receives,
|
||||
minimizing its chances of being selected to do the load balancing
|
||||
work that runs in SCHED_SOFTIRQ context.
|
||||
3. To the extent possible, keep the CPU out of the kernel when it
|
||||
is non-idle, for example, by avoiding system calls and by
|
||||
forcing both kernel threads and interrupts to execute elsewhere.
|
||||
This further reduces the number of scheduler-clock interrupts
|
||||
received by the de-jittered CPU.
|
||||
HRTIMER_SOFTIRQ: Do all of the following:
|
||||
1. To the extent possible, keep the CPU out of the kernel when it
|
||||
is non-idle. For example, avoid system calls and force both
|
||||
kernel threads and interrupts to execute elsewhere.
|
||||
2. Build with CONFIG_HOTPLUG_CPU=y. Once boot completes, force the
|
||||
CPU offline, then bring it back online. This forces recurring
|
||||
timers to migrate elsewhere. If you are concerned with multiple
|
||||
CPUs, force them all offline before bringing the first one
|
||||
back online. Once you have onlined the CPUs in question, do not
|
||||
offline any other CPUs, because doing so could force the timer
|
||||
back onto one of the CPUs in question.
|
||||
RCU_SOFTIRQ: Do at least one of the following:
|
||||
1. Offload callbacks and keep the CPU in either dyntick-idle or
|
||||
adaptive-ticks state by doing all of the following:
|
||||
a. Build with CONFIG_RCU_NOCB_CPU=y, CONFIG_RCU_NOCB_CPU_ALL=y,
|
||||
CONFIG_NO_HZ_FULL=y, and, in addition ensure that the CPU
|
||||

2. Enable RCU to do its processing remotely via dyntick-idle by

doing all of the following:
|

a. Build with CONFIG_NO_HZ=y and CONFIG_RCU_FAST_NO_HZ=y.
|
||||
b. Ensure that the CPU goes idle frequently, allowing other
|
||||
CPUs to detect that it has passed through an RCU quiescent
|

state. If the kernel is built with CONFIG_NO_HZ_FULL=y,

Purpose: Execute RCU callbacks in CONFIG_RCU_BOOST=y kernels.

To reduce its OS jitter, do at least one of the following:
|
||||
1. Build the kernel with CONFIG_PREEMPT=n. This prevents these
|
||||
kthreads from being created in the first place, and also obviates
|
||||
the need for RCU priority boosting. This approach is feasible
|
||||
for workloads that do not require high degrees of responsiveness.
|
||||
2. Build the kernel with CONFIG_RCU_BOOST=n. This prevents these
|
||||
kthreads from being created in the first place. This approach
|
||||
is feasible only if your workload never requires RCU priority
|
||||
boosting, for example, if you ensure frequent idle time on all
|
||||
CPUs that might execute within the kernel.
|
||||
3. Build with CONFIG_RCU_NOCB_CPU=y and CONFIG_RCU_NOCB_CPU_ALL=y,
|
||||
which offloads all RCU callbacks to kthreads that can be moved
|
||||
off of CPUs susceptible to OS jitter. This approach prevents the
|
||||
rcuc/%u kthreads from having any work to do, so that they are
|
||||
never awakened.
|
||||
4. Ensure that the CPU never enters the kernel, and, in particular,
|
||||
avoid initiating any CPU hotplug operations on this CPU. This is
|
||||
another way of preventing any callbacks from being queued on the
|
||||
CPU, again preventing the rcuc/%u kthreads from having any work
|

to do.

|
||||
1. Use affinity, cgroups, or other mechanism to force these kthreads
|
||||
to execute on some other CPU.
|
||||
2. Build with CONFIG_RCU_NOCB_CPUS=n, which will prevent these
|
||||
kthreads from being created in the first place. However, please

note that this will not eliminate OS jitter, but will instead
|

shift it to RCU_SOFTIRQ.

Name: watchdog/%u

||||
Purpose: Detect software lockups on each CPU.
|

To reduce its OS jitter, do at least one of the following:

||||
1. Build with CONFIG_LOCKUP_DETECTOR=n, which will prevent these
|
||||
kthreads from being created in the first place.
|
||||
2. Echo a zero to /proc/sys/kernel/watchdog to disable the
|
||||
watchdog timer.
|
||||
3. Echo a large number of /proc/sys/kernel/watchdog_thresh in
|
||||
order to reduce the frequency of OS jitter due to the watchdog
|
||||
timer down to a level that is acceptable for your workload.

When in an active transaction that takes a signal, we need to be careful with

the stack. It's possible that the stack has moved back up after the tbegin.
|

The obvious case here is when the tbegin is called inside a function that

returns before a tend. In this case, the stack is part of the checkpointed
|

transactional memory state. If we write over this non transactionally or in

stack pointer will be back at the tbegin but our in memory stack won't be valid

anymore.
|

|

To avoid this, when taking a signal in an active transaction, we need to use

the stack pointer from the checkpointed state, rather than the speculated

4. Enumeration and Discovery
|
||||
----------------------------
|
||||
|
||||
When rio_init_mports() is called it scans a list of registered master ports and
|
||||
calls an enumeration or discovery routine depending on the configured role of a
|
||||
master port: host or agent.
|
||||
4.1 Overview
|
||||
------------
|
||||
|
||||
RapidIO subsystem configuration options allow users to specify enumeration and
|
||||
discovery methods as statically linked components or loadable modules.
|
||||
An enumeration/discovery method implementation and available input parameters
|
||||
define how any given method can be attached to available RapidIO mports:
|
||||
simply to all available mports OR individually to the specified mport device.
|
||||
|
||||
Depending on selected enumeration/discovery build configuration, there are
|
||||
several methods to initiate an enumeration and/or discovery process:
|
||||
|
||||
(a) Statically linked enumeration and discovery process can be started
|
||||
automatically during kernel initialization time using corresponding module
|
||||
parameters. This was the original method used since introduction of RapidIO
|
||||
subsystem. Now this method relies on enumerator module parameter which is
|
||||
'rio-scan.scan' for existing basic enumeration/discovery method.
|
||||
When automatic start of enumeration/discovery is used a user has to ensure
|
||||
that all discovering endpoints are started before the enumerating endpoint
|
||||
and are waiting for enumeration to be completed.
|
||||
Configuration option CONFIG_RAPIDIO_DISC_TIMEOUT defines time that discovering
|
||||
endpoint waits for enumeration to be completed. If the specified timeout
|
||||
expires the discovery process is terminated without obtaining RapidIO network
|
||||
information. NOTE: a timed out discovery process may be restarted later using
|
||||
a user-space command as it is described later if the given endpoint was
|
||||
enumerated successfully.
|
||||
|
||||
(b) Statically linked enumeration and discovery process can be started by
|
||||
a command from user space. This initiation method provides more flexibility
|
||||
for a system startup compared to the option (a) above. After all participating
|
||||
endpoints have been successfully booted, an enumeration process shall be
|
||||
started first by issuing a user-space command, after an enumeration is
|
||||
completed a discovery process can be started on all remaining endpoints.
|
||||
|
||||
(c) Modular enumeration and discovery process can be started by a command from
|
||||
user space. After an enumeration/discovery module is loaded, a network scan
|
||||
process can be started by issuing a user-space command.
|
||||
Similar to the option (b) above, an enumerator has to be started first.
|
||||
|
||||
(d) Modular enumeration and discovery process can be started by a module
|
||||
initialization routine. In this case an enumerating module shall be loaded
|
||||
first.
|
||||
|
||||
When a network scan process is started it calls an enumeration or discovery
|
||||
routine depending on the configured role of a master port: host or agent.
|
||||
|
||||

The enumeration and discovery routines use RapidIO maintenance transactions

||||
to access the configuration space of devices.

The enumeration process is implemented according to the enumeration algorithm
|
||||
outlined in the RapidIO Interconnect Specification: Annex I [1].
|
||||
4.2 Automatic Start of Enumeration and Discovery
|
||||
------------------------------------------------
|
||||
|
||||
Automatic enumeration/discovery start method is applicable only to built-in
|
||||
enumeration/discovery RapidIO configuration selection. To enable automatic
|
||||
enumeration/discovery start by existing basic enumerator method set use boot
|
||||
command line parameter "rio-scan.scan=1".
|
||||
|
||||
This configuration requires synchronized start of all RapidIO endpoints that
|
||||
form a network which will be enumerated/discovered. Discovering endpoints have
|
||||
to be started before an enumeration starts to ensure that all RapidIO
|
||||
controllers have been initialized and are ready to be discovered. Configuration
|
||||
parameter CONFIG_RAPIDIO_DISC_TIMEOUT defines time (in seconds) which
|
||||
a discovering endpoint will wait for enumeration to be completed.
|
||||
|
||||
When automatic enumeration/discovery start is selected, basic method's
|
||||
initialization routine calls rio_init_mports() to perform enumeration or
|
||||
discovery for all known mport devices.
|
||||
|
||||
Depending on RapidIO network size and configuration this automatic
|
||||
enumeration/discovery start method may be difficult to use due to the
|
||||
requirement for synchronized start of all endpoints.
|
||||
|
||||
4.3 User-space Start of Enumeration and Discovery
|
||||
-------------------------------------------------
|
||||
|
||||
User-space start of enumeration and discovery can be used with built-in and
|
||||
modular build configurations. For user-space controlled start RapidIO subsystem
|
||||
creates the sysfs write-only attribute file '/sys/bus/rapidio/scan'. To initiate
|
||||
an enumeration or discovery process on specific mport device, a user needs to
|
||||
write mport_ID (not RapidIO destination ID) into that file. The mport_ID is a
|
||||
sequential number (0 ... RIO_MAX_MPORTS) assigned during mport device
|
||||
registration. For example for machine with single RapidIO controller, mport_ID
|
||||
for that controller always will be 0.
|
||||
|
||||
To initiate RapidIO enumeration/discovery on all available mports a user may
|
||||
write '-1' (or RIO_MPORT_ANY) into the scan attribute file.
|
||||
|
||||
4.4 Basic Enumeration Method
|
||||
----------------------------
|
||||
|
||||
This is an original enumeration/discovery method which is available since
|
||||
first release of RapidIO subsystem code. The enumeration process is
|
||||
implemented according to the enumeration algorithm outlined in the RapidIO
|
||||
Interconnect Specification: Annex I [1].
|
||||
|
||||
This method can be configured as statically linked or loadable module.
|
||||
The method's single parameter "scan" allows to trigger the enumeration/discovery
|
||||
process from module initialization routine.
|
||||
|
||||
This enumeration/discovery method can be started only once and does not support
|
||||
unloading if it is built as a module.
|
||||

||||
algorithm. When a new device is found, the enumerator takes ownership of that

4.5 Adding New Enumeration/Discovery Method
|
||||
-------------------------------------------
|
||||
|
||||
RapidIO subsystem code organization allows addition of new enumeration/discovery
|
||||
methods as new configuration options without significant impact to to the core
|
||||
RapidIO code.
|
||||
|
||||
A new enumeration/discovery method has to be attached to one or more mport
|
||||
devices before an enumeration/discovery process can be started. Normally,
|
||||
method's module initialization routine calls rio_register_scan() to attach
|
||||
an enumerator to a specified mport device (or devices). The basic enumerator
|
||||
implementation demonstrates this process.

RapidIO destination ID) into this file. The mport_ID is a sequential
|
||||
number (0 ... RIO_MAX_MPORTS) assigned to the mport device.
|
||||
For example, for a machine with a single RapidIO controller, mport_ID
|
||||
for that controller always will be 0.
|
||||
To initiate RapidIO enumeration/discovery on all available mports
|
||||
a user must write '-1' (or RIO_MPORT_ANY) into this attribute file.
