# Intel Vision Driver
2+
3+
This repository supports Intel Vision Driver on Intel Lunar Lake (LNL) CVS-enabled Platforms
4+
5+
## Dependencies
6+
* Intel LNL platform BIOS and CVS device
7+
* Linux kernel v6.7-rc8 or later
8+
* Intel LJCA USB driver, adding LNL GPIO PID (INTC10B5) support
9+
10+
11+
## Build instructions
12+
Ways to build the USBIO drivers
13+
1. build out of kernel source tree
14+
2. build with kernel source tree and build with dkms aren't supported yet
15+
16+
Build was tested on Ubuntu 22.04 LNL CVS platform running kernel v6.7-rc8
17+
18+
### Build out of kernel source tree
19+
* Prerequisite: 6.7-rc8 (or later) kernel with ```ljca``` and ```gpio_ljca``` module/driver loaded, header and build packages, to install required package
20+
```
21+
$ sudo apt-get install build-essential
22+
```
23+
24+
To compile the Intel Vision driver:
25+
```
26+
$ cd drivers.platform.aicv.vision-linux
27+
$ make clean
28+
$ make
29+
```
30+
31+
### Check LJCA drivers are loaded before vision driver can be installed
32+
```
33+
$ lsmod | grep -e ljca -e gpio_ljca
34+
```
35+
36+
### Installing the vision driver
37+
```
38+
$ sudo insmod intel_cvs.ko
39+
```
40+
41+
### Uninstall the vision driver
42+
```
43+
$ sudo rmmod intel_cvs
44+
```
45+
