try going through this Ubuntu Sound Troubleshooting procedure. I'm wondering if it could be related to Pulseaudio which works in tandem with Alsa.

I was told for sound, that has to be probed via Acpi with the current drivers so you should put that setting back.

@mauser_270, the goodix touchscreen driver developer made some changes and asked for this to be tested when you can:

Code: Select all

     
     git clone https://github.com/blocksonic/gt9xx
     cd gt9xx
     sudo make install
     sudo depmod -a
     sudo modprobe -rv goodix_backport
     sudo modprobe -v goodix_backport
     sudo reboot
I omitted the 'make clean' and 'make' steps since I already built it on kernel 4.8-rc5 which you're running. It's shouldn't hurt to recompile/rebuild it (make clean, make) but it's not necessary unless you're booted up on a different kernel version.
Please send me the link to the dmesg log for the TS working and not-working. There is extra debug info in this version the developer added.

It's complaining about a missing firmware file
Goodix-TS i2c-GDIX1001:00: Direct firmware load for goodix_9111_cfg.bin failed with error -2
which is not surprising as this ID 9111 is new and specific to the Chuwi Hi12. Will inform the developer and get back to you.

@mauser,
Is there a pattern for this wrong values of the touches? There is a setting in the device configuration that switches the X and Y axes. Do these wrong touches follow this pattern or are they just random? Like it's flipped top to bottom?

The developer gave me directions how how to create this firmware file but it's a bit complicated for me. It might take a while. I'll let you know. Meanwhile I would revert back to the previous driver for now. I'll need you to have the TS working to create this firmware file once I figure out all the steps.

Just a note. I haven't given up on this topic. Just got busy with some other things. Shifting this into a more slow progress thing.
I need to rebuild the driver with the dev's latest code. cheers, -Brad-

That's a pretty broad question. Things are inching forward for support of many Cherry-Trail based tablets and little by little more touchscreen drivers are being added or updated in the kernel currently being worked on for release ( 4.8 ). Plus changes to the audio subsystem (ALSA version 1.1.2) to get it working on the Microsoft Surface 3, which is also a Cherry-Trail tablet. So I expect things to gradually get better with Kernel releases 4.8 and 4.9.
If you're wanting to buy a device, try to find out what WiFi and touchscreen devices it uses so you can find out if Linux drivers for it are available and people have tested that particular tablet. Here, on TechTablets, XDA-developers, etc.

Just to document the status of the subject of the touchscreen driver, here is the latest comment from the developer: https://bugzilla.kernel.org/show_bug.cgi?id=156511#c20 This is what I need to get to...

Right. I was hoping it will work without the need to provide this configuration file, but it seems it is not the case.

You can generate a configuration file based on the the device configuration when it is working. You can find documentation on how to do that in my latest patches (that have not been merged yet) [1].

I noticed you are not using the latest version of the upstream Goodix driver on github. There are no major differences between these version, but it might be best to use the latest version. You can use my github version of the driver [2].

First you need to read a working configuration from the device. You might need to revert the patch that enables reset for the Chuwi tablet [3]. With the patches from my github you can read the device configuration from /sys/class/input/input6/device/dump. Following the instructions in the documentation [1], you can generate a goodix_9111_cfg.bin file that needs to be copied to /lib/firmware. To have the configuration updated, you need to have the patch that enables reset for the Chuwi tablet [3].

Let me know if something is not clear.

Re: Linux Mint 18 Working on Chuwi Hi12 Tablet PC 64 Bit Cherry Trail Quad Core

Post by bbaker6212 »

@mauser_270, I rebuilt the goodix touchscreen driver with the developer's recent changes which have Chuwi Hi12 specific changes in it. Basically it requires loading a firmware file during init/configuration. You can pull the new driver code and build it from my Github repo as normal/before. https://github.com/blocksonic/gt9xx

Now, as for the required firmware file, going through the directions given by the developer on how to create the firmware file, let's try it. The quoted block below are the directions and I'll try to summarize here...

Build the new driver:

Code: Select all

git clone https://github.com/blocksonic/gt9xx
cd gt9xx
make clean
make
sudo make install
sudo depmod -a
sudo modprobe -rv goodix_backport
sudo modprobe -v goodix_backport
reboot, then come back to the same gt9xx directory...

Dump the default configuration of the TS device to a file:
First you need to find out what device number it is. After starting up do...

Code: Select all

dmesg | grep "Goodix Capacitive TouchScreen as /devices"
And you should see something like "[ 10.370058] input: Goodix Capacitive TouchScreen as /devices/pci0000:00/808622C1:05/i2c-13/i2c-GDIX1001:00/input/input6" which indicates it's running as device input6

Now run the following replacing "inputX" with the the above device string:

Code: Select all

cat /sys/class/input/inputX/device/dump_config > goodix_9111_cfg
if that didn't show anything try it with just "dump" at the end of the line instead of "dump_config"

paste the contents of the resulting file goodix_9111_cfg here. We may need to change some of these default values for this particular touchscreen.
But for now, lets just try creating the firmware file with the default (dumped) config values:

run the firware creation script: [EDIT:] This script may not run properly - I'm waiting for the developer to reply to my question about a setting in it.

Code: Select all

./goodix-generate-fw.sh goodix_9111_cfg 
I can't test this script since I cannot generate the goodix_9111_cfg file, but you should now have the firmware file goodix_9111_cfg.bin

Copy it to the firmware directory:

Code: Select all

cp goodix_9111_cfg.bin /lib/firmware
reboot and test the touchscreen and copy dmesg output to Pastebin.
2. Device configuration
=====================================

Goodix touchscreen devices have a set of registers that specify configuration
information for the device. The configuration information has a specific format
described in the Goodix data sheet. It includes X/Y resolution, maximum
supported touch points, interrupt flags, various sensitivity factors and
settings for advanced features (like gesture recognition).

For more details check the Goodix data sheet for format of Configuration
Registers.

2.1. Reading device configuration
=====================================

The devices have an initial default configuration that can be read through
the sysfs interface (/sys/class/input/inputX/device/dump_config).

2.2. Updating device configuration
======================================

To update the device configuration, the driver needs to control the interrupt
and reset GPIO pins (configured through ACPI/device tree). Devices that do
not have the GPIO pins properly configured will not be able to update the
configuration.

To update the configuration, you need a configuration firmware file. You can
obtain this file from the vendor or generate one starting from the default
configuration of the device (/sys/class/input/inputX/device/dump_config).

At init, the driver will read the configuration firmware file and update
the device configuration. The configuration data is read with request_firmware
from "goodix_<id>_cfg.bin", where <id> is the product id read from the device
(e.g.: goodix_911_cfg.bin for Goodix GT911, goodix_9271_cfg.bin for GT9271).

Below are instructions on how to generate a valid configuration starting from
the device default configuration.

1. Dump the default configuration of the device to a file:
$ cat /sys/class/input/inputX/device/dump_config > goodix_<id>_cfg

2. Make the needed changes to the configuration (e.g. change resolution of
X/Y axes, maximum reported touch points, switch X,Y axes, etc.). For more
details check the Goodix data sheet for format of Configuration Registers.
[edit:] I cannot find any datasheet for the 9111 only the 911, 9110, 9113, etc.
http://www.datasheetspdf.com/PDF/GT911/1007756/1 5 point touch
http://www.datasheetspdf.com/PDF/GT9113/957630/1 10 point touch

3. Generate a valid configuration starting from goodix_<id>_cfg.
After making changes, you need to recompute the checksum of the entire
configuration data, set Config_Fresh to 1 and generate the binary config
firmware image. This can be done using a helper script similar to the
one below:
[edit:] the script goodix-generate-fw.sh is included in my Github repo if you clone it (@bbaker6212)

4. Copy the binary config firmware in the appropriate location
(e.g. /lib/firmware), using the name goodix_<id>_cfg.bin.

5. Check that the new firmware was successfully written to the device
after reboot. Config_Fresh is reset to 0 after a successful update of the
configuration.

Hello!
I have Chuwi Hi 12 dualboot tablet.
Recently I have tried to fix touchscreen configuration in android. Unfortunately, android driver cannot load any configuration.
I made the binary configuration with GtpAdbTool utility and I used a DefaultCFG string from file 'Touchsetting.gt'.
You can see the result in the attachment. I hope it will help you.

There is a topic about another Goodix touchscreen, but configuration process is similar:

Thanks for the information. I'm not sure if having that binary file will help. I think we need the file goodix_9111_cfg generated from dumping the default configuration (shown above). That way we can change it (some of the settings) if needed and regenerate the binary firmware file. Do you have the default config (text) file? Is there a way to generate this file from the goodix_9111_cfg.bin file that you attached?
