Proportional Weight division of bandwidth
|
||||
-----------------------------------------
|
||||
You can do a very simple testing of running two dd threads in two different
|
||||
cgroups. Here is what you can do.
|
||||
|
||||
- Enable Block IO controller
|
||||
CONFIG_BLK_CGROUP=y
|
||||
|
||||
- Enable group scheduling in CFQ
|
||||
CONFIG_CFQ_GROUP_IOSCHED=y
|
||||
|
||||
- Compile and boot into kernel and mount IO controller (blkio); see
|
||||
cgroups.txt, Why are cgroups needed?.
|
||||
|
||||
mount -t tmpfs cgroup_root /sys/fs/cgroup
|
||||
mkdir /sys/fs/cgroup/blkio
|
||||
mount -t cgroup -o blkio none /sys/fs/cgroup/blkio
|
||||
|
||||
- Create two cgroups
|
||||
mkdir -p /sys/fs/cgroup/blkio/test1/ /sys/fs/cgroup/blkio/test2
|
||||
|
||||
- Set weights of group test1 and test2
|
||||
echo 1000 > /sys/fs/cgroup/blkio/test1/blkio.weight
|
||||
echo 500 > /sys/fs/cgroup/blkio/test2/blkio.weight
|
||||
|
||||
- Create two same size files (say 512MB each) on same disk (file1, file2) and
|
||||
launch two dd threads in different cgroup to read those files.
|
||||
|
||||
sync
|
||||
echo 3 > /proc/sys/vm/drop_caches
|
||||
|
||||
dd if=/mnt/sdb/zerofile1 of=/dev/null &
|
||||
echo $! > /sys/fs/cgroup/blkio/test1/tasks
|
||||
cat /sys/fs/cgroup/blkio/test1/tasks
|
||||
|
||||
dd if=/mnt/sdb/zerofile2 of=/dev/null &
|
||||
echo $! > /sys/fs/cgroup/blkio/test2/tasks
|
||||
cat /sys/fs/cgroup/blkio/test2/tasks
|
||||
|
||||
- At macro level, first dd should finish first. To get more precise data, keep
|
||||
on looking at (with the help of script), at blkio.disk_time and
|
||||
blkio.disk_sectors files of both test1 and test2 groups. This will tell how
|
||||
much disk time (in milliseconds), each group got and how many sectors each
|
||||
group dispatched to the disk. We provide fairness in terms of disk time, so
|
||||
ideally io.disk_time of cgroups should be in proportion to the weight.

CFQ sysfs tunable
|
||||
=================
|
||||
/sys/block/<disk>/queue/iosched/slice_idle
|
||||
------------------------------------------
|
||||
On a faster hardware CFQ can be slow, especially with sequential workload.
|
||||
This happens because CFQ idles on a single queue and single queue might not
|
||||
drive deeper request queue depths to keep the storage busy. In such scenarios
|
||||
one can try setting slice_idle=0 and that would switch CFQ to IOPS
|
||||
(IO operations per second) mode on NCQ supporting hardware.
|
||||
|
||||
That means CFQ will not idle between cfq queues of a cfq group and hence be
|
||||
able to driver higher queue depth and achieve better throughput. That also
|
||||
means that cfq provides fairness among groups in terms of IOPS and not in
|
||||
terms of disk time.
|
||||
|
||||
/sys/block/<disk>/queue/iosched/group_idle
|
||||
------------------------------------------
|
||||
If one disables idling on individual cfq queues and cfq service trees by
|
||||
setting slice_idle=0, group_idle kicks in. That means CFQ will still idle
|
||||
on the group in an attempt to provide fairness among groups.
|
||||
|
||||
By default group_idle is same as slice_idle and does not do anything if
|
||||
slice_idle is enabled.
|
||||
|
||||
One can experience an overall throughput drop if you have created multiple
|
||||
groups and put applications in that group which are not driving enough
|
||||
IO to keep disk busy. In that case set group_idle=0, and CFQ will not idle
|
||||
on individual groups and throughput should improve.

* Wiznet w5x00
|
||||
|
||||
This is a standalone 10/100 MBit Ethernet controller with SPI interface.
|
||||
|
||||
For each device connected to a SPI bus, define a child node within
|
||||
the SPI master node.
|
||||
|
||||
Required properties:
|
||||
- compatible: Should be one of the following strings:
|
||||
"wiznet,w5100"
|
||||
"wiznet,w5200"
|
||||
"wiznet,w5500"
|
||||
- reg: Specify the SPI chip select the chip is wired to.
|
||||
- interrupts: Specify the interrupt index within the interrupt controller (referred
|
||||
to above in interrupt-parent) and interrupt type. w5x00 natively
|
||||
generates falling edge interrupts, however, additional board logic
|
||||
might invert the signal.
|
||||
- pinctrl-names: List of assigned state names, see pinctrl binding documentation.
|
||||
- pinctrl-0: List of phandles to configure the GPIO pin used as interrupt line,
|
||||
see also generic and your platform specific pinctrl binding
|
||||
documentation.
|
||||
|
||||
Optional properties:
|
||||
- spi-max-frequency: Maximum frequency of the SPI bus when accessing the w5500.
|
||||
According to the w5500 datasheet, the chip allows a maximum of 80 MHz, however,
|
||||
board designs may need to limit this value.
|
||||
- local-mac-address: See ethernet.txt in the same directory.
|
||||
|
||||
|
||||
Example (for Raspberry Pi with pin control stuff for GPIO irq):

Enabling the driver and kconfig options
|
||||
================================================
|
||||
|
||||
| mlx5 core is modular and most of the major mlx5 core driver features can be selected (compiled in/out)
|
||||
| at build time via kernel Kconfig flags.
|
||||
| Basic features, ethernet net device rx/tx offloads and XDP, are available with the most basic flags
|
||||
| CONFIG_MLX5_CORE=y/m and CONFIG_MLX5_CORE_EN=y.
|
||||
| For the list of advanced features please see below.
|
||||
|
||||
**CONFIG_MLX5_CORE=(y/m/n)** (module mlx5_core.ko)
|
||||
|
||||
| The driver can be enabled by choosing CONFIG_MLX5_CORE=y/m in kernel config.
|
||||
| This will provide mlx5 core driver for mlx5 ulps to interface with (mlx5e, mlx5_ib).
|
||||
|
||||
|
||||
**CONFIG_MLX5_CORE_EN=(y/n)**
|
||||
|
||||
| Choosing this option will allow basic ethernet netdevice support with all of the standard rx/tx offloads.
|
||||
| mlx5e is the mlx5 ulp driver which provides netdevice kernel interface, when chosen, mlx5e will be
|
||||
| built-in into mlx5_core.ko.
|
||||
|
||||
|
||||
**CONFIG_MLX5_EN_ARFS=(y/n)**
|
||||

Devlink health reporters
|
||||
========================
|
||||
|
||||
tx reporter
|
||||
-----------
|
||||
The tx reporter is responsible of two error scenarios:
|
||||
|
||||
- TX timeout
|
||||
Report on kernel tx timeout detection.
|
||||
Recover by searching lost interrupts.
|
||||
- TX error completion
|
||||
Report on error tx completion.
|
||||
Recover by flushing the TX queue and reset it.
|
||||
|
||||
TX reporter also support Diagnose callback, on which it provides
|
||||
real time information of its send queues status.
|
||||
|
||||
User commands examples:
|
||||
|
||||
- Diagnose send queues status::
|
||||
|
||||
$ devlink health diagnose pci/0000:82:00.0 reporter tx
|
||||
|
||||
- Show number of tx errors indicated, number of recover flows ended successfully,
|
||||
is autorecover enabled and graceful period from last recover::
|
||||
|
||||
$ devlink health show pci/0000:82:00.0 reporter tx
|
||||
|
||||
fw reporter
|
||||
-----------
|
||||
The fw reporter implements diagnose and dump callbacks.
|
||||
It follows symptoms of fw error such as fw syndrome by triggering
|
||||
fw core dump and storing it into the dump buffer.
|
||||
The fw reporter diagnose command can be triggered any time by the user to check
|
||||
current fw status.
|
||||
|
||||
User commands examples:
|
||||
|
||||
- Check fw heath status::
|
||||
|
||||
$ devlink health diagnose pci/0000:82:00.0 reporter fw
|
||||
|
||||
- Read FW core dump if already stored or trigger new one::
|
||||
|
||||
$ devlink health dump show pci/0000:82:00.0 reporter fw
|
||||
|
||||
NOTE: This command can run only on the PF which has fw tracer ownership,
|
||||
running it on other PF or any VF will return "Operation not permitted".
|
||||
|
||||
fw fatal reporter
|
||||
-----------------
|
||||
The fw fatal reporter implements dump and recover callbacks.
|
||||
It follows fatal errors indications by CR-space dump and recover flow.
|
||||
The CR-space dump uses vsc interface which is valid even if the FW command
|
||||
interface is not functional, which is the case in most FW fatal errors.
|
||||
The recover function runs recover flow which reloads the driver and triggers fw
|
||||
reset if needed.
|
||||
|
||||
User commands examples:
|
||||
|
||||
- Run fw recover flow manually::
|
||||
|
||||
$ devlink health recover pci/0000:82:00.0 reporter fw_fatal
|
||||
|
||||
- Read FW CR-space dump if already strored or trigger new one::
|
||||
|
||||
$ devlink health dump show pci/0000:82:00.1 reporter fw_fatal
|
||||
|
||||
NOTE: This command can run only on PF.

PHY interface modes
|
||||
===================
|
||||
|
||||
The PHY interface mode supplied in the phy_connect() family of functions
|
||||
defines the initial operating mode of the PHY interface. This is not
|
||||
guaranteed to remain constant; there are PHYs which dynamically change
|
||||
their interface mode without software interaction depending on the
|
||||
negotiation results.
|
||||
|
||||
Some of the interface modes are described below:
|
||||
|
||||
``PHY_INTERFACE_MODE_1000BASEX``
|
||||
This defines the 1000BASE-X single-lane serdes link as defined by the
|
||||
802.3 standard section 36. The link operates at a fixed bit rate of
|
||||
1.25Gbaud using a 10B/8B encoding scheme, resulting in an underlying
|
||||
data rate of 1Gbps. Embedded in the data stream is a 16-bit control
|
||||
word which is used to negotiate the duplex and pause modes with the
|
||||
remote end. This does not include "up-clocked" variants such as 2.5Gbps
|
||||
speeds (see below.)
|
||||
|
||||
``PHY_INTERFACE_MODE_2500BASEX``
|
||||
This defines a variant of 1000BASE-X which is clocked 2.5 times faster,
|
||||
than the 802.3 standard giving a fixed bit rate of 3.125Gbaud.
|
||||
|
||||
``PHY_INTERFACE_MODE_SGMII``
|
||||
This is used for Cisco SGMII, which is a modification of 1000BASE-X
|
||||
as defined by the 802.3 standard. The SGMII link consists of a single
|
||||
serdes lane running at a fixed bit rate of 1.25Gbaud with 10B/8B
|
||||
encoding. The underlying data rate is 1Gbps, with the slower speeds of
|
||||
100Mbps and 10Mbps being achieved through replication of each data symbol.
|
||||
The 802.3 control word is re-purposed to send the negotiated speed and
|
||||
duplex information from to the MAC, and for the MAC to acknowledge
|
||||
receipt. This does not include "up-clocked" variants such as 2.5Gbps
|
||||
speeds.
|
||||
|
||||
Note: mismatched SGMII vs 1000BASE-X configuration on a link can
|
||||
successfully pass data in some circumstances, but the 16-bit control
|
||||
word will not be correctly interpreted, which may cause mismatches in
|
||||
duplex, pause or other settings. This is dependent on the MAC and/or
|
||||
PHY behaviour.

~~~~~~~~~~~~~~~~
|

|

Whenever an out of order segment is detected the driver requests
|

that the ``ktls`` software fallback code encrypt it. If the segment's
|
||||
sequence number is lower than expected the driver assumes retransmission
|
||||
and doesn't change device state. If the segment is in the future, it

may imply a local drop, the driver asks the stack to sync the device

to the next record state and falls back to software.

Resync request is indicated with:

Stream scan resynchronization

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

When the device gets out of sync and the stream reaches TCP sequence

numbers more than a max size record past the expected TCP sequence number,

the device starts scanning for a known header pattern. For example

Stack-driven resynchronization
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
The driver may also request the stack to perform resynchronization
|
||||
whenever it sees the records are no longer getting decrypted.
|
||||
If the connection is configured in this mode the stack automatically
|
||||
schedules resynchronization after it has received two completely encrypted

records.

The stack waits for the socket to drain and informs the device about
|

the next expected record number and its TCP sequence number. If the
|

records continue to be received fully encrypted stack retries the

synchronization with an exponential back off (first after 2 encrypted

records, then after 4 records, after 8, after 16... up until every

Requirements
|
||||
============
|
||||
|
||||
A host with a USB port. Ideally, either a UHCI (Intel) or OHCI
|
||||
(Compaq and others) hardware port should work.
|
||||
A host with a USB port running a Linux kernel with RIO 500 support enabled.
|
||||
|
||||
A Linux development kernel (2.3.x) with USB support enabled or a
|
||||
backported version to linux-2.2.x. See http://www.linux-usb.org for
|
||||
more information on accomplishing this.
|
||||
The driver is a module called rio500, which should be automatically loaded
|
||||
as you plug in your device. If that fails you can manually load it with
|
||||
|
||||
A Linux kernel with RIO 500 support enabled.
|
||||
modprobe rio500
|
||||
|
||||
'lspci' which is only needed to determine the type of USB hardware
|
||||
available in your machine.
|
||||
|
||||
Configuration
|
||||
|
||||
Using `lspci -v`, determine the type of USB hardware available.
|
||||
|
||||
If you see something like::
|
||||
|
||||
USB Controller: ......
|
||||
Flags: .....
|
||||
I/O ports at ....
|
||||
|
||||
Then you have a UHCI based controller.
|
||||
|
||||
If you see something like::
|
||||
|
||||
USB Controller: .....
|
||||
Flags: ....
|
||||
Memory at .....
|
||||
|
||||
Then you have a OHCI based controller.
|
||||
|
||||
Using `make menuconfig` or your preferred method for configuring the
|
||||
kernel, select 'Support for USB', 'OHCI/UHCI' depending on your
|
||||
hardware (determined from the steps above), 'USB Diamond Rio500 support', and
|
||||
'Preliminary USB device filesystem'. Compile and install the modules
|
||||
(you may need to execute `depmod -a` to update the module
|
||||
dependencies).
|
||||
|
||||
Add a device for the USB rio500::
|
||||
Udev should automatically create a device node as soon as plug in your device.
|
||||
If that fails, you can manually add a device for the USB rio500::
|
||||
|
||||
mknod /dev/usb/rio500 c 180 64
|
||||
|
||||
Set appropriate permissions for /dev/usb/rio500 (don't forget about
|
||||
group and world permissions). Both read and write permissions are
|
||||
In that case, set appropriate permissions for /dev/usb/rio500 (don't forget
|
||||
about group and world permissions). Both read and write permissions are
|
||||
required for proper operation.
|
||||
|
||||
Load the appropriate modules (if compiled as modules):
|
||||
|
||||
OHCI::
|
||||
|
||||
modprobe usbcore
|
||||
modprobe usb-ohci
|
||||
modprobe rio500
|
||||
|
||||
UHCI::
|
||||
|
||||
modprobe usbcore
|
||||
modprobe usb-uhci (or uhci)
|
||||
modprobe rio500
|
||||
|
||||
That's it. The Rio500 Utils at: http://rio500.sourceforge.net should
|
||||
be able to access the rio500.
|
||||
|
||||
Limits
|
||||
======
|
||||
|
||||
You can use only a single rio500 device at a time with your computer.
