But we don't want to do that unconditionally. That's what we do now,
and we decided to change it. We want to do that only if the kernel
somehow knows that the user hasn't installed firmware with that name.
Yes, that's right.
introducing some means for userland to tell the kernel which pieces of
firmware are available, so that the kernel does not even ask for those
that aren't.
Now I see the logic of it. However, it still seems to me that the
directory which normally holds firmware files could effectively be
that list.
Here is how it would work:
The function that requests loading firmware look in the firmware
directory for the relevant file name. If it finds a file, it requests
loading the firmware. Otherwise, if the firmware file is free, it
requests loading the firmware. But if the file is nonfree and not present,
it gives an error message, "Device not supported".
Wouldn't this do the job?
