| Mauro Carvalho Chehab | 12bcf90 | 2020-03-10 13:10:17 +0100 | [diff] [blame] | 46 | To build and install, you should run:: |
| Linus Torvalds | 1da177e | 2005-04-16 15:20:36 -0700 | [diff] [blame] | 47 | |
| Mauro Carvalho Chehab | 12bcf90 | 2020-03-10 13:10:17 +0100 | [diff] [blame] | 48 | make && make modules_install && make install |
| 49 | |
| 50 | Once the new Kernel is booted, saa7134 driver should be loaded automatically. |
| 51 | |
| 52 | Depending on the card you might have to pass ``card=<nr>`` as insmod option. |
| 53 | If so, please check :doc:`saa7134-cardlist` for valid choices. |
| 54 | |
| 55 | Once you have your card type number, you can pass a modules configuration |
| 56 | via a file (usually, it is either ``/etc/modules.conf`` or some file at |
| 57 | ``/etc/modules-load.d/``, but the actual place depends on your |
| 58 | distribution), with this content:: |
