* Backports not building configured drivers @ 2018-08-27 22:01 Marlon Smith 2018-08-28 4:42 ` Luca Coelho 0 siblings, 1 reply; 6+ messages in thread From: Marlon Smith @ 2018-08-27 22:01 UTC (permalink / raw) To: backports Hi everyone, I'm using backports 4.14 to build for a custom kernel 3.14. That kernel includes the RT2800 wifi driver, and if I configure backports with menuconfig to build a newer version of that driver it works perfectly. However, if I configure backports to build the RTL8821 driver, which my kernel otherwise does not include, the driver never gets built and backports shows it as not selected the next time I run menuconfig. Is this expected behaviour? Is there something I can do to force this driver to build? Thanks!

Check the list of dependencies for the driver and make sure they are included in your 3.14 kernel. -- Luca. -- To unsubscribe from this list: send the line "unsubscribe backports" in ^ permalink raw reply [flat|nested] 6+ messages in thread

The requirements in the backports 4.14 menuconfig are listed as follows: Depends on: WLAN [=y] && WLAN_VENDOR_REALTEK [=y] && RTL_CARDS [=m] && m && BP_MODULES [=y] && PCI [=y] I can find the symbol WLAN_VENDOR_REALTEK in the backports 4.14 menuconfig but not in the 3.14 kernel's menuconfig. Does this mean I can't use the driver with this kernel? -- To unsubscribe from this list: send the line "unsubscribe backports" in ^ permalink raw reply [flat|nested] 6+ messages in thread

I have no idea if the backports code will run, or even build, in kernels that old, but I think it would be safe for you to edit the symbol WLAN_VENDOR_REALTEK out of that "depends on" line in the configuration menu. At least, that will get you to the next problem. :) Larry -- To unsubscribe from this list: send the line "unsubscribe backports" in ^ permalink raw reply [flat|nested] 6+ messages in thread

Does this mean I > can't use the driver with this kernel? No, actually the symbol is enabled? See the [=y] above. The above looks like it is actually enabled though, so something else must be going on? johannes -- To unsubscribe from this list: send the line "unsubscribe backports" in ^ permalink raw reply [flat|nested] 6+ messages in thread

The setting I was missing in the kernel was that I need to have PCI enabled. I'm not sure why the backports menuconfig said PCI [=y], since it was not enabled in the kernel, but once I enabled it backports built the wifi driver correctly. Thanks again for the help!
