 |
|
Hello again everyone,
when I compile a certain driver (lets say sndhda-intel) into the kernel (i.e. not as a module), how do I pass parameters to that driver that I would usually pass to the module using modprobe?
As an example:
When I compile snd-hda-intel as a module I would usually call it up using
| Code: | | modprobe snd-hda-intel model=acer |
Now, when I compile snd-hda-intel into the kernel - how do I pass the module=acer parameter to the kernel driver?
Thanks in advance, best regards,
Christian.

From Documentation/kernel-parameters.txt | Quote: | Module parameters for modules that are built into the kernel image are specified on the kernel command line with the module name plus '.' plus parameter name, with '=' and value if appropriate, such as:
usbcore.blinkenlights=1 |
so you would need | Code: | | snd_hda_intel.model=acer |
I've only recently discovered this so you are benefiting from fresh knowledge
