imanager's Issues

unexpected hwmon delay on boot

I've recently tried to update the iManager driver for my Linux variant and I noticed that the statistics that imanager-hwmon module populates do not show any updates until after five (5) minutes of uptime. Before the update, an invoke of the sensors command would display updated information for the "imanager_hwmon-isa-0000" block right away:

imanager_hwmon-isa-0000
Adapter: ISA adapter
+12V:        +11.79 V  (min =  +0.00 V, max =  +0.00 V)  ALARM
+5V:          +0.23 V  (min =  +0.00 V, max =  +0.00 V)  ALARM
VBat:         +2.92 V  (min =  +0.00 V, max =  +0.00 V)  ALARM
FAN CPU:        0 RPM  (min = 2000 RPM, max = 6000 RPM)
FAN SYS1:    1665 RPM  (min = 2000 RPM, max = 6000 RPM)
Temp CPU:     +40.0 C  (low  = +40.0 C, high = +85.0 C)
Temp SYS1:    +40.0 C  (low  = +40.0 C, high = +85.0 C)

After updating to a newer version, the sensors information shows the following:

imanager_hwmon-isa-0000
Adapter: ISA adapter
+12VS0:       +0.00 V  (min =  +0.00 V, max =  +0.00 V)
+5VS0:        +0.00 V  (min =  +0.00 V, max =  +0.00 V)
+3.3VS0:      +0.00 V  (min =  +0.00 V, max =  +0.00 V)
FAN CPU:        0 RPM  (min = 2000 RPM, max = 6000 RPM)
FAN SYS1:    2000 RPM  (min = 2000 RPM, max = 6000 RPM)
Temp CPU:     +63.0 C  (low  = +40.0 C, high = +85.0 C)
Temp SYS1:    +63.0 C  (low  = +40.0 C, high = +85.0 C)

No voltages, RPMs or temperature values are updated until (almost exactly) five (5) minutes of uptime:

imanager_hwmon-isa-0000
Adapter: ISA adapter
+12VS0:      +11.79 V  (min =  +0.00 V, max =  +0.00 V)  ALARM

+3.3VS0:      +2.92 V  (min =  +0.00 V, max =  +0.00 V)  ALARM
FAN CPU:        0 RPM  (min = 2000 RPM, max = 6000 RPM)
FAN SYS1:    1665 RPM  (min = 2000 RPM, max = 6000 RPM)
Temp CPU:     +39.0 C  (low  = +40.0 C, high = +85.0 C)
Temp SYS1:    +39.0 C  (low  = +40.0 C, high = +85.0 C)

Explicit version/commit information:

All kernel variants are based off of Linux v4.4.30.
Works with no issues with iManager driver v1.4.0 (commit fe07cd3).
Observed issue in iManager driver v1.4.0 (commit 0524834) and iManager driver v1.4.0 (commit b35f807).
Modules used: imanager-core, imanager-bl and imanager-hwmon
Observed issue on hardware: custom hardware using a SOM-5892 as well as an Advantech SOM-DB5800 development carrier board unit.

suggestion | mark release file with interim postfix

The following is a suggestion towards marking the RELEASE file version entry for specific release cycle events. If the following doesn't fit in your own release cycle process or is just not really desired, feel free to ignore this request.

The following suggests that the interim release value found in RELEASE should be appended with a -git postfix (ex. v1.4.0-git). This would allow a developer to easily confirm the non-stable variant release from just using the source. Doing this, however, requires an official release to involve two (2) commits: a release commit (removing -git postfix and tagging) and a kickoff cycle commit (updating new version target and re-adding postfix). Consider the following examples: release commit and kickoff cycle commit.

Question: Does GPIO driver support interrupts?

I have successfully built and used the GPIO driver. I noticed that the inputs do not have an edge file in /sys/class/gpio/gpioXXX/. Based on that, I'm assuming that the GPIOs do not support interrupts. Is that a function of the hardware or the kernel driver in gpio-imanager?

Question

I've got an IT8528 chip or at least so does it seem, it's a Razer Blade 14' 2014 system and the IT87 module reports an unknown chip 0x8520 revision a.
However upon building, installing and loading the module I get:
insmod: ERROR: could not insert module imanager-core.ko: No such device

This is on Gentoo, under 4.7.2-gentooSources.

Am I doing something wrong?

Question about implementing the watchdog using C#

I'm fairly new to the linux/embedded space but need to implement the watchdog for our SOM. So far I have successfully compiled and installed the module and am able to use the watchdog, but want to know if I am using the correct commands as the driver was intended. I will need to implement this using C#, and plan to run these commands using a C# Process object. Is there a better way to use the watchdog functionality?

To enable and feed the watchdog from the terminal, I am using:
echo 1 > /dev/watchdog1
To stop the watchdog, I use:
echo 0 > /dev/watchdog1
To change the timeout from the default, I use:
rmmod imanager_wdt
insmod /lib/modules/$(uname -r)/extra/imanager/imanager_wdt.ko timeout=60

This seems to work just fine, but I wanted to know if these commands are the correct usage or if there is a better way.
Thanks in advance

"write error: Invalid argument" when exporting GPIO

I am working on an Advantech MIO-5271 with Ubuntu 16.04 and kernel 4.4.0-31. After building and installing the kernel modules as described in the README, I am unable to export the GPIOs. My steps are below. Any help would be greatly appreciated. Thanks!

i have AIMB-274
and i can access 3 fan's rpm with windows driver

but with this driver i can olny access cpu fan's rpm and one 3pin fan's rpm

and i can access pch temperature and cpu temp with windows driver..
but only CPU temp with this driver.

windows drivers access extra register??

Is AIMB-275 board supported?

Dear Sirs,
We are running a linux 4.9.13 kernel on top of a AIMB-275 Mini-ITX motherboard.

The README of this module says AIMB board family have this kind of chip.
However the ec_read_chip function in imanager_init is returning ffff when loading the module.
(Below the log of modprobe printing the "No such device" error message)
It looks like there is no such chip at that address for our board.

Is there another iManager driver implementation?
How can we verify we have the Advantech EC based chip ITE IT8518 or IT8528?

Thank you for your support.
