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
|
||||
to be de-jittered is marked as an adaptive-ticks CPU using
|
||||
the "nohz_full=" boot parameter. Bind the rcuo kthreads
|
||||
to housekeeping CPUs, which can tolerate OS jitter.
|
||||
b. 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. 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,
|
||||
userspace execution also allows other CPUs to detect that

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

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.
