|
|
```
|

|
|
|

|
|
## 2. Download the kernel source:
|
||
|
|
|
||
|
|
- Visit kernel.org
|
||
|

||
|
|
tar xvf linux-5.x.y.tar.xz
|
||
|
|
cd linux-5.x.y
|
||
|

||
|
|
## 4. Configure the kernel:
|
||
|
|
|

||
|
|
```
|
||

|
|
```bash
|

||
|
|
```
|
||
|
|
- Update the config for the new version:
|
||
|
|
```bash
|
||
|
|
make oldconfig
|
||
|
|
```
|
||
|
|
|
||
|
|
## 5. Build the kernel:
|
||
|
|
|
||
|
|

|
||
|
|
make -j$(nproc)
|
||
|
|
```
|
||
|
|
|
||
|
|
## 6. Build and install modules:
|
||

## 7. Install the kernel:

|
||
|
|
```
|
||
|
|
|
||
|
