hid-multitouch

[grandixximo]

I want to use a touchscreen, but when I install the eci kernel the hid-multitouch driver is not included, could I have the source code of the kernel so that I can build and enable it, or can you make a build available with hid-multitouch enabled, or give me a way to be able to use a touchscreen properly with the eci kernel?

I succeded in enabling the hid-multitouch, if anyone needs it this is roughly what I did on Debian 11 bullseye

Steps Taken to Enable hid-multitouch Driver:

Install Linux Source:

Installed the source for the 5.10 kernel using:

bash

Copy code

sudo apt install linux-source-5.10

Build the Kernel:

Built the 5.10.218-1 kernel from source, disabling some certificates during the build process.

Extract Relevant Drivers:

Copied the /drivers/hid folder from the built kernel source.

Created a DKMS module directory at /usr/src/hid-multitouch-1.0.

Adjust Header Files:

Copied necessary .h files from /usr/src/hid-multitouch-1.0/intel-ish-hid/ishtp to /usr/src/hid-multitouch-1.0/intel-ish-hid/ipc.

Create DKMS Configuration:

Created a dkms.conf file in /usr/src/hid-multitouch-1.0 with the following content:

plaintext

Copy code

PACKAGE_NAME="hid-multitouch"

PACKAGE_VERSION="1.0"

BUILT_MODULE_NAME[0]="hid-multitouch"

DEST_MODULE_LOCATION[0]="/updates/dkms"

AUTOINSTALL="yes"

MAKE[0]="make -C ${kernel_source_dir} M=${dkms_tree}/${PACKAGE_NAME}/${PACKAGE_VERSION}/build CFLAGS=\"-I${kernel_source_dir}/drivers/hid/intel-ish-hid/ishtp\""

CLEAN="make -C ${kernel_source_dir} M=${dkms_tree}/${PACKAGE_NAME}/${PACKAGE_VERSION}/build clean"

Build and Install DKMS Module:

Added the module to DKMS:

bash

Copy code

sudo dkms add -m hid-multitouch -v 1.0

Built the module for the current vanilla kernel:

bash

Copy code

sudo dkms build -m hid-multitouch -v 1.0

Install Intel ESE Kernel Headers and Kernel:

Installed the headers and kernel for 5.10.179-rt87-intel-ese-standard-lts-rt+. The DKMS install failed initially due to the hid-multitouch driver being disabled in the kernel configuration.

Enable Driver in Kernel Configuration:

Modified the kernel configuration file to enable CONFIG_HID_MULTITOUCH:

bash

Copy code

sudo pluma /usr/src/linux-headers-5.10.179-rt87-intel-ese-standard-lts-rt+/.config

Added or modified the line:

plaintext

Copy code

CONFIG_HID_MULTITOUCH=m

Update Grub and Reboot:

Updated Grub configuration:

bash

Copy code

sudo update-grub

Rebooted into the 5.10.179-rt87-intel-ese-standard-lts-rt+ kernel.

Manually Install DKMS Module:

Ran the DKMS install manually, which succeeded:

bash

Copy code

sudo dkms install -m hid-multitouch -v 1.0

Verify Touchscreen Functionality:

After rebooting, the touchscreen was working as expected.

By following these steps, you successfully enabled and installed the hid-multitouch driver for the 5.10.179-rt87-intel-ese-standard-lts-rt+ kernel.
