Hello all,
I am beginning with Linux Kernel development. So I am trying to make
the IIO tasks posted on kernelnewbies DOT org.
But I got stuck with this problem that I am describing you hereafter
hoping that someone could bring me any feedback.
Many thanks,
Miguel ROBLES
----------
DESCRIPTION
-----------
After loading the corresponding IIO modules and mountig the configfs
filesystem
I can not create an instance device with mkdir using the command:
$ sudo mkdir /config/iio/devices/dummy/my_dummy_device
Killed
I get the "Killed" message and looking at my syslog file, I got the
warning
"refcount_t: increment on 0; use-after-free" followed by an "Oops"
message.
When trying to execute the command one more time, the execution never
finishes.
------
CONTEXT
-------
- Tried on 2 linux kernel releases:
- kernel: 4.10 (commit: 4977ab6)
- Kernel: 4.11 (commit: ec3b93a)
- Compiled with config file including the following options for IIO:
#
# IIO dummy driver
#
CONFIG_IIO_DUMMY_EVGEN=m
CONFIG_IIO_SIMPLE_DUMMY=m
CONFIG_IIO_SIMPLE_DUMMY_EVENTS=y
CONFIG_IIO_SIMPLE_DUMMY_BUFFER=y
CONFIG_IIO_CONFIGFS=m
Do you also have CONFIG_IIO_SW_DEVICE right?
Yes, and the value is: CONFIG_IIO_SW_DEVICE=m.
Thank you,
Miguel
Will try to have a look at this asap.
thanks,
Daniel.
