Building a kernel without vc4-hdmi ALSA card

Tue Jul 02, 2019 3:15 pm

Hi there,

As I have reported, vc4-hdmi does not seem to work with baremetal ALSA (it has NOTHING to do with 64bit kernels, look:, so I want to build my own kernel without it, since it seems that it is not possible to disable it via config.txt, kernel command line, etc...
So, I have seen that all the vc4-hdmi mentions are in

Code: Select all

What would be a "less hacky" way to disable it there so it is not brought up on boot? (ie: ALSA should be the ONLY card!)

For example, I have been thinking that making

Code: Select all


Code: Select all

return -ENODEV
would work, but is it a good idea to do so?


NOTE: Ideally, I would prefer vc4-hdmi to work instead of the BCM2835 ALSA driver, but it does not seem like this will be fixed anytime soon, does it?
