|
|
|
|
## Prebuild module
|
|
|
|
https://github.com/fbelavenuto/arpl-modules
|
|
|
|
Eg: https://github.com/fbelavenuto/arpl-modules/blob/main/geminilake-4.4.180/igc.ko
|
|
|
|
## Build
|
|
|
|
### 1. Setup develop environment
|
|
|
|
#### Prepare Environment
|
|
|
|
Refer: https://help.synology.com/developer-guide/getting_started/prepare_environment.html
|
|
|
|
Assume `platform=geminilake`, `version=7.1`, working directory is `/synology-toolkit`
|
|
|
|
Now the build env is `/synology-toolkit/build_env/ds.geminilake-7.1`
|
|
|
|
#### Enter chrooot
|
|
|
|
```
|
|
sudo chroot /synology-toolkit/build_env/ds.geminilake-7.1
|
|
```
|
|
|
|
#### Clone source code
|
|
|
|
```
|
|
cd /usr/src/
|
|
git clone https://github.com/jim3ma/synology-igc.git
|
|
```
|
|
|
|
### 2. Build module
|
|
|
|
```shell
|
|
cd /usr/src/synology-igc/
|
|
make -C /usr/local/x86_64-pc-linux-gnu/x86_64-pc-linux-gnu/sys-root/usr/lib/modules/DSM-7.1/build M=$PWD modules
|
|
```
|
|
|
|
### 3. Load module
|
|
|
|
Copy `igc.ko` to target machine
|
|
|
|
#### Find i225/i226 pci device
|
|
|
|
```
|
|
03:00.0 Ethernet controller: Intel Corporation Ethernet Controller I225-V (rev 03)
|
|
```
|
|
|
|
```
|
|
insmod igc.ko debug=16 # enable debug log
|
|
echo igc > /sys/bus/pci/devices/0000:03:00.0/driver_override
|
|
echo 0000:03:00.0 > /sys/bus/pci/drivers_probe
|
|
ip link set up eth1 # in my machine, the nic name is eth1
|
|
```
|
|
|
|
## TODO
|
|
|
|
1. tc support
|
|
2. igc: Enable internal i225 PPS - https://github.com/torvalds/linux/commit/64433e5bf40abf893c7edbc60899bdcdd7c70b76
