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,

0.009806

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

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

I think again we have issue with the channel index.

Quoted 1 line

From logs

** (process:10579): DEBUG: No new data available on 'iio:device3' ** (process:10579): DEBUG: process_scan_1: channel_index: 2, chan_name:
in_accel_x, channel_data_index: 0 location: 8
** (process:10579): DEBUG: process_scan_1: channel_index: 1, chan_name:
in_accel_y, channel_data_index: 1 location: 4
** (process:10579): DEBUG: process_scan_1: channel_index: 0, chan_name:
in_accel_z, channel_data_index: 2 location: 0

** (process:10579): DEBUG: Read from IIO on 'iio:device0': -230, -968, 23
** (process:10579): DEBUG: Accel sent by driver (quirk applied): 2, 9, 0

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"

Srinivas

Not much changed even after reverting that commit.

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

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

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

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.

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.

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

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

Can you try attached patch for both 4.7 and 4.8 kernel?

Thanks,

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.

Hi Bastien,

My original pull request for issue #99 already had this change. Somehow
when merged to main, this change was removed.
May be just revert and pull again.

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.

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...

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.
