Hello Srinivas and Others,

[Please CC me in replies. I'm not subscribed to the list]

This email is in regard to an odd behavior, we seems to have discovered with
iio-sensor-proxy version 1.2 and the iio driver in Linux, maybe particular to
the following driver.

Looking at your bug report, raw readings are around magnitude 1000.
1000*0.009806 = 9.81

Given accelerations in IIO are in m/s^2 I'm slightly confused...

Guessing the iio-sensor-proxy might be getting it's idea of what counts
as orientation from the wrong place?  

I couldn't immediately see where it figures that out...

Ah, found it. In orientation.c (obvious I guess)

Too late in the day here for me to spot exactly why the rounding
errors being introduced are resulting in this concluding that
the orientation isn't changing significantly.

Perhaps stick a line in the sensor proxy to spit out the
computed 'rotation' value?

Thanks,

Which seems is correct value after scale for atleast one of the axis.

I think again we have issue with the channel index.

Again somehow we think that X is at byte index 8, Y at byte index 4,
and Z at byte index 8. Looks like it got reversed.
It should be 0, 4 and 8 respectively.

Can you try reverting this commit in iio-sensor-proxy? If it is then
this is some indexing issue we still need to address:

"buffer-utils: Fix orientation axis switch using 4.8 kernel"

Thanks,
Srinivas

Not much changed even after reverting that commit.


With iio-sensor-proxy, 1.2, I get:

rrs@learner:/var/tmp/Debian-Build/Result$ monitor-sensor 
    Waiting for iio-sensor-proxy to appear
+++ iio-sensor-proxy appeared
=== Has accelerometer (orientation: right-up)
=== Has ambient light sensor (value: 0.000000, unit: lux)
    Accelerometer orientation changed: left-up
    Accelerometer orientation changed: right-up
    Accelerometer orientation changed: left-up
    Accelerometer orientation changed: right-up
- --- iio-sensor-proxy vanished, waiting for it to appear


Notice that there is no 'normal' orientation mode reported.

Now reverting back to 1.1 of iio-sensor-proxy, I get:

+++ iio-sensor-proxy appeared
=== Has accelerometer (orientation: undefined)
=== Has ambient light sensor (value: 0.000000, unit: lux)
+++ Accelerometer appeared
    Accelerometer orientation changed: undefined
+++ Light sensor appeared
    Light changed: 0.000000 (lux)
    Accelerometer orientation changed: right-up
    Accelerometer orientation changed: normal
    Accelerometer orientation changed: right-up


This is on Linux 4.8-rc6.

Sigh. I think this is the second time I get this wrong. The code to
calculate the orientation expects 1G ~= 0x100. So the driver is
correct, and I need to fix this again in iio-sensor-proxy.

Sorry about that.

After reverting your changes[1], and applying Bastien's change [2], it is better
as in now it can detect all orientation types. But they do not align with the
actual physical orientation of the device. They are flipped to the actual
orientation of the device. Logs linked [3]. Tested on Linux 4.8-rc6

I was surprised why the sorting function didn't work (it should be
qsort compliant). We need some way not to depend on the order of
scan_elements read from file system. So we need to fix this.

Thanks,
Srinivas

My guess:
-       return (int) (info_1->index - info_2->index);
+       return ((int) info_1->index - (int) info_2->index);

Ritesh, could you try to change those lines in compare_channel_index()
in src/iio-buffer-utils.c and capture another log if it fails?

Cheers

That did not seem to change anything. I've put up the log at:

Thank you Srini. With this patch, it works perfect on 4.8-rc6 kernel.
Log is attached for your reference.

I'll also confirm for 4.7 soon.

If you can explain the change, I'd be all for it, because I don't
understand it.

Subject: [PATCH] Fix sorting of channels

As per the documentation of g_ptr_array_sort
"Note that the comparison function for g_ptr_array_sort() doesn't take the
pointers from the array as arguments, it takes pointers to the pointers in
the array"
So the arguments to the function
	compare_channel_index (gconstpointer a, gconstpointer b)
needs to be dereferenced to get pointer to iio_channel_info.
