Surface Pro 3 - To Do List

[Matt Parnell]

Feel free to add more if I'm missing any:

• Screen rotation
• Auto brightness
• Stylus
• Two Finger Scrolling
• Volume Rockers (fixed already?)
  
• ???
  

I've found on Linux at least, with the SP3 patches, that most of the devices including the accelerometer and light sensors are already exposed. iio-proxy detects them and you can scale the brightness up and down if you just make a little bash script to echo the proper values...

I'm not super adept with Android like I am with Linux, so for fixing these issues, I may require instruction or help from an actual Android dev.

to see how to enable it.

Welcome on board.

[Matt Parnell]

Thank you for the information, I'll have to see what I can do! Hopefully I won't ask any questions in the future that sound too stupid - either way, I'm glad to be back around.

In all honesty the recent behavior of Micorsoft is enough to push me to work more on Linux and Android, as these are great pieces of hardware, but Windows is a privacy nightmare.

What is the current state of Android on the Surface Pro 3? I have a SP3 with a faulty SSD drive. I can boot Ubuntu from microSD, but I hope I can do the same with Android.

What version should I use? Android-x86 5.1? Or an older version?
And what are the steps I need to take?

[Matt Parnell]

I think we just spoke? I hope you've managed to boot Android by now? I know it is possible, but I believe you may need to unlock secure boot, and configure the UEFI a bit to boot it. The XDA thread should have a decent-ish guide.

[Jon West]

That was me. I will use this thread to post what I find in trying to fix the touchscreen issues on the SP3. First on my list is to apply these to our kernel and see what I get. https://github.com/matthewwardrop/linux-surfacepro3/commit/795180bc6c990b052cb1a3fdbeb54e172ff3cfff

[Matt Parnell]

Nice, let me know how it goes!

Has anyone gotten rotation, cameras and touch properly working?

For me camera works kind of, but it's in the wrong orientation. Rotation works only through apps like Rotation Control that put rotation buttons in the notification list. Touch sometimes stops working.

However, stability etc. has gotten much better lately with the fixes people have done, great!

[James Chai]

Actually the only thing not working is auto rotation and Wifi.

Gyrometer is connected to I2C and wifi requires a patch in the mwifiex_pcie driver in kernel.

[James Chai]

And As of Linux kernel 4.8 all those driver will be merged into mainline kernel.

Awesome! Thanks for the heads-up. It'll be interesting to try them out once 4.8 is out and available to us!

If Android x86 is not going to move to 4.8 kernel, we might need to do a backport.

[Matt Parnell]

 Isn't auto rotate just modifying a bash script? I know auto brightness is not that difficult (I tested under plain Linux with a dirty script), and I would assume that since Android X86 uses a bash script for rotation that too shouldn't be super hard to configure.

[Henri Koivuneva]

I found this python script https://github.com/tiggerite/mint-17.3-for-surface-pro-3/blob/master/utils/autorotate

Works well in tiggerite's Linux mint 17.3, I couldn't get it to work on Android (with SL4A and my very limited python knowledge). Any way to convert that to a bash script or otherwise use it? The matrices for rotation are there etc!

I've built 4.8rc5 and rc6 from Mauro Rossi's repo but they unfortunately freeze on the sp3 with 6.0.1r66 &  r68 64-bit (builds here http://goo.gl/VRBjLK ) gotta try rc2, they had used that for Surface 3 so perhaps it's more stable?

[Povilas Staniulis]

I guess the script is for X which Android does not use.
Android has a sensor HAL which reads data from sensor devices and
interprets in accordingly.
There's already a HAL driver for I2C sensors, not sure if it would work
though.

Do you have /sys/bus/iio/devices/iio:device0 ?

What's the property ro.hardware.sensors ?

[James Chai]

yes and hsb

[Henri Koivuneva]

Hi! Thank you for the help. Here are the logs and stuff, is there anything I could do to help figure it out? Do we need a new driver in drivers/iio/accel? Or what's needed to possibly fix auto rotation on the Surface Pro 3?

Attachments: dmesg, getprop output, logcat, accel-related contents from /sys/bus/iio/devices/iio:device0 in landscape mode. Please tell me if the output in all modes is needed and I'll send!

[ro.hardware.sensors]: [hsb]

[ro.product.manufacturer]: [Microsoft Corporation]
[ro.product.model]: [Surface Pro 3]
[ro.product.name]: [android_x86_64]

Using Mauro Rossi's kernel 4.11 with your newest code from OSDN, with your marshmallow-x86 MESA branch.

Here's the built ISO in case it's needed: goo.gl/oNlXo8

Best wishes,
Henri

Hmm. This is an old thread.
Please remind what issue it is.

I can just say the sensor HAL is set correctly
and the iio nodes seems good.
Everything seems OK.

If it doesn't work, you have to debug
the sensor HAL or driver yourself.

BTW, the Surface 3 (non-pro) has a similar issue.
The driver is loaded but it doesn't generate
correct data on rotating.
Yes, the driver needs to be fixed.
But it's very hard for the linux community since
nobody has the detailed spec of the hardware.
A Red Hat developer has talked to me about that.
They have tried to ask data sheet from Microsoft
but no response as everyone expects.

Right! Thank you. The issue is that automatic rotation doesn't work. The sensors seem to register changes when turning the device around, but it's not conveyed to the UI(?) to rotate. Thus, using an app like RotationControl by CrapeMyrtle is needed.

I was looking at device/generic/common/init.sh:235 and hardware/libsensors, it seems there are some things for different devices related to rotation...

So I was wondering if it's possible to somehow add similar fixes for the Surface Pro 3, with the available sensor data when rotating? Or is that completely impossible because Microsoft hasn't shared the detailed spec? How about the accel matrix from https://github.com/tiggerite/mint-17.3-for-surface-pro-3/blob/master/utils/autorotate ?

inputnames=[

"Atmel Atmel maXTouch Digitizer",

"NTRG0001:01 1B96:1B05"

]

orientations=[

"normal",

"inverted",

"left",

"right"

]

matrices=[

[1,0,0,0,1,0,0,0,1],

[-1,0,1,0,-1,1,0,0,1],

[0,-1,1,1,0,0,0,0,1],

[0,1,0,-1,0,1,0,0,1]

]

[Henri Koivuneva]

Sorry I forgot to attach the picture. It looks like the sensors are going between 0-65536 depending on how I'm holding the device...so the kernel might be recognizing it / works with it?

Looks like the automatic rotation work in normal linux distros.
If so that means the driver is OK.
You just need to fix the HAL.
And since the sensor HAL has been set up (to hsb),
you can use some sensors test apps to check
what data are read.

The Intel's hsb HAL is under hardware/intel/libsensors.
Alternatively, you can set the sensors HAL to iio
to see if it works better.

Thank you for the tips, this has been very helpful! I'll go through it this weekend and try to find out what's wrong there and what's been done in the Linux distros if they don't just use a script to rotate. 

That tiggerite Linux Mint script seems to be written for X which we don't use.. Interesting. I'll report back if I find anything!
