openBMC pwm-fan control policy

openBMC pwm-fan control policy

[Landon]

[-- Attachment #1: Type: text/plain, Size: 276 bytes --]

Hello everyone, I would like to ask what is supported by openBMC pwm-fan control policy?
Can it be linked with temperature and current? Whether the pwm-fan output can be controlled by the corresponding temperature and current?
Are there any instructions or references?
Thanks!

https://github.com/openbmc/phosphor-pid-control should be flexible
enough for the purpose. Is it missing something you need?

hello, paul


Thank you for your reply!

I've read the "phosphor-pid-control ".
But I didn't read about the linked between temperature and current.

could you give me an example?



Thanks!

add: I just want to know in OpenBMC by reading different temperature values or current values to control the fan output, so as to cool down, how does this strategy work? An example of this.

This is using temperature values to control the fans so as to cool
down, it works by configuring phosphor-pid-control appropriately, I
hope it's enough of an example:

https://github.com/openbmc/entity-manager/blob/master/configurations/R1000%20Chassis.json

If you think phosphor-pid-control is missing some documentation please
read its source code and send documentation patches for review.

Thank you! 
I have read it :  https://github.com/openbmc/entity-manager/blob/master/configurations/R1000%20Chassis.json
But I don't understand,

Is there an explanation for this part?

Are there general instructions on how to control fan output by temperature?



and how to use phosphor-pid-control  to set this ?
 
Is there“ phosphor-pid-control ”the instructions for this part?
Thank you very much !

Hello,

Please read phosphor-pid-control documentation:
https://github.com/openbmc/phosphor-pid-control
https://github.com/openbmc/phosphor-pid-control/blob/master/configure.md
https://github.com/openbmc/phosphor-pid-control/blob/master/tuning.md
https://github.com/openbmc/phosphor-pid-control/tree/master/examples

Keep in mind that there are two different ways to configure phosphor-
pid-control: statically with JSON config files and dynamically with
DBUS (generally, using EntityManager JSON configuration) and same
parameters with this two ways mostly have different names.
The way you want to use is generally depend on either you use EM for
your platform or not.

Re: openBMC pwm-fan control policy

[Andrei Kartashev]

Sorry, I probably miss your question.

I still don't understand, what kind of help do you need, but I will try
to explain the idea:
PID-control daemon use concept of the PID systems, where you have
inputs (sensors) and outputs (FANs). To configure PIDs in pid-control
the zone concept is used: thermal zone can have several fans and
several sensors. 
Then you should select PID-loop type and set parameters for each sensor
and FAN. For normal temperature sensor you generally will use normal
PID-loop, were you setup PID coefficients and setpoint (target
temperature). When the value of one (or more) sensor exceed setpoint
PID-control will increase the speed of the fans in the zone trying to
keep temperatures below the setpoints.
For current sensors you probably should use stepwise mode, but I'm not
familiar here.

Sorry, I probably miss your question.

I still don't understand, what kind of help do you need, but I will try
to explain the idea:
PID-control daemon use concept of the PID systems, where you have
inputs (sensors) and outputs (FANs). To configure PIDs in pid-control
the zone concept is used: thermal zone can have several fans and
several sensors. 
Then you should select PID-loop type and set parameters for each sensor
and FAN. For normal temperature sensor you generally will use normal
PID-loop, were you setup PID coefficients and setpoint (target
temperature). When the value of one (or more) sensor exceed setpoint
PID-control will increase the speed of the fans in the zone trying to
keep temperatures below the setpoints.
For current sensors you probably should use stepwise mode, but I'm not
familiar here.

Hello,

Please read phosphor-pid-control documentation:
https://github.com/openbmc/phosphor-pid-control
https://github.com/openbmc/phosphor-pid-
control/blob/master/configure.md
https://github.com/openbmc/phosphor-pid-
control/blob/master/tuning.md
https://github.com/openbmc/phosphor-pid-
control/tree/master/examples

Keep in mind that there are two different ways to configure
phosphor-
pid-control: statically with JSON config files and dynamically
with
DBUS (generally, using EntityManager JSON configuration) and
same
parameters with this two ways mostly have different names.
The way you want to use is generally depend on either you use
EM
for
your platform or not.

 Are there general instructions on how to control fan output

 and how to use phosphor-pid-control  to set this ?
  
 Is there“ phosphor-pid-control ”the instructions for this

 This is using temperature values to control the fans so as

 down, it works by configuring phosphor-pid-control
appropriately, I
 hope it's enough of an example:

 If you think phosphor-pid-control is missing some

 please
 read its source code and send documentation patches for

[-- Attachment #1.1: Type: text/plain, Size: 754 bytes --]

hello,


I use https://github.com/AspeedTech-BMC/openbmc sdk v7.02 now,
the Aspeed openbmc is forked from https://github.com/openbmc/openbmc
and I found a problem is :
I input the user password in the login screen, and enter the web，then I Operate some menus ，All of a sudden，the screen will jumps back to the login screen, and input the user password in the login screen,  enter the web again,
And will jumps back to the login screen Once again, the problem sometimes more than once.

And I found Operate the "sensors" menus View the Sensor List Trigger it Higher frequency.




I try update the webui-vue  “webui-vue_git.bb” of the SRCREV, but There is no effect, the problem is  still existence.
sorry to have troubled you so much!

Thanks !

The data in the SquashFS volume is corrupted.  By "the error appears sometimes"
do you mean that:

1. Sometimes you build an image and it is garbage but other times you build an
   image and it works fine?

2. Some machines can be flashed with an image and they work, but other machines
   can be flashed with an image and they fail?

3. The same machine can be flashed with an image and sometimes it works and
   sometimes it doesn't?

4. A machine can be flashed once and then some reboots work fine and some
   reboots do not?

#1 would likely be a problem with your flash layout where the squashfs is
getting corrupted by an earlier part of the image being too big.

#2-4 would likely be some hardware and/or SPI configuration issue.

I would likely try slowing down the SPI bus speeds and/or turning of QSPI if
you have that enabled to get something stable and then work from there.  If this
is a new board it is possible you have some SI issues on the SPI line
(reflections, bad capacitance, incorrect level shifter IC for SPI speeds, etc.).

Hi,

I have a similar issue that is fixed by this change: 
https://gerrit.openbmc-project.xyz/c/openbmc/bmcweb/+/49318.

Please check if this change helps with your issue.  I think all we're 
missing is test data to merge that, so if you have any data, it may help 
with merging that change.

Thanks!
-Jason

[-- Attachment #1.1: Type: text/plain, Size: 754 bytes --]

hello,


I use https://github.com/AspeedTech-BMC/openbmc sdk v7.02 now,
the Aspeed openbmc is forked from https://github.com/openbmc/openbmc
and I found a problem is :
I input the user password in the login screen, and enter the web，then I Operate some menus ，All of a sudden，the screen will jumps back to the login screen, and input the user password in the login screen,  enter the web again,
And will jumps back to the login screen Once again, the problem sometimes more than once.

And I found Operate the "sensors" menus View the Sensor List Trigger it Higher frequency.




I try update the webui-vue  “webui-vue_git.bb” of the SRCREV, but There is no effect, the problem is  still existence.
sorry to have troubled you so much!

Thanks !

This seems just as likely to be caused by a bmcweb change as a webui-vue change.
If you're using a fork (Aspeed's tree) you're far less likely to be able to
update bmcweb without there being lots of other compatibility issues with
internal BMC services.

OpenBMC Switching function of web

[Landon]

[-- Attachment #1: Type: text/plain, Size: 495 bytes --]



hello~


I would like to ask openBMC how to realize the switch on and off function of Web, and what is the guidance ？
This is "Reboot"  and "shut down" for my web interface, and I want to "power on" and "shut down".
I transplant the “\meta-quanta\meta-q71l\recipes-phosphor\quanta-powerctrl”，generate "poweron.sh" and "poweroff.sh" in “/usr/bin”, 
but Click on the web "shut down", it is no response.
so, how do I realize the switch function of web.


Thank you very much !

hello~

now I use aspeed ast2600 openbmc.
At first, I set pwer state command: but failed!

so I modify the "\meta-aspeed-sdk\meta-ast2600-sdk\conf\machine\ast2600-emmc.conf", remove the "x86-power-control"...  :

RE: OpenBMC state manager problem

[-- Attachment #1.1: Type: text/plain, Size: 4351 bytes --]

Hi Landon,
According your question, provide some suggestions for you refer it.

You can check journal log first for keyword “power-control” to debug why your x86-power-control cannot be activated.
BTW, x86-power-control uses default json file (power-config-host0.json) for GPIO configuration.
You also need to check this json file according your hardware.

For busctl set command debugging, you can use dbus-monitor to get more information why the name of property/interface is not activatable.

Best regards,
Tim

but, after I update openbmc for the lastest the version, it can't enter the system ：

hello~
now I use aspeed ast2600 openbmc.
At first, I set pwer state command: but failed!

root@ast2600-emmc:~# busctl set-property xyz.openbmc_project.State.Host /xyz/openbmc_project/state/host0 xyz.openbmc_project.State.Host CurrentHostState s "xyz.openbmc_project.State.Host.HostState.Off" Failed to set property CurrentHostState on interface xyz.openbmc_project.State.Host: The name is not activatable
root@ast2600-emmc:~# busctl set-property xyz.openbmc_project.State.Host /xyz/openbmc_project/state/host0 xyz.openbmc_project.State.Host CurrentHostState s "xyz.openbmc_project.State.Host.HostState.Running" Failed to set property CurrentHostState on interface xyz.openbmc_project.State.Host: The name is not activatable
so I modify the "\meta-aspeed-sdk\meta-ast2600-sdk\conf\machine\ast2600-emmc.conf", remove the "x86-power-control"...  :
PREFERRED_PROVIDER_virtual/obmc-system-mgmt = "packagegroup-aspeed-obmc"
PREFERRED_PROVIDER_virtual/obmc-host-ipmi-hw = "phosphor-ipmi-kcs"
# I remove the 2 lines :
#VIRTUAL-RUNTIME_obmc-host-state-manager ?= "x86-power-control"
#VIRTUAL-RUNTIME_obmc-chassis-state-manager ?= "x86-power-control"
EXTRA_IMAGEDEPENDS:append = "\
   aspeed-image-recoveryuart \
   aspeed-image-emmcboot \


After,  I set pwer state command OK :
