You were just asking it to build a subdirectory, not a specific individual file, and when you do that it looks at the configuration settings. It's always good to ensure that you actually build the files you modify before sending patches out. thanks, greg k-h

DMA support via gb-netlink and gbridge

by Kyle Harding

Hey all, new member here! As the subject line suggests, our development hardware does not support UniPro so we were looking at a guest kernel solution with TCP/IP transport over gbridge. However, one of the SDIO bus devices is a wifi module that requires DMA. Is this possible over the current gb-netlink/gbridge to your knowledge? Cheers, -- *—* *Kyle Harding* Embedded Linux Engineer, balena.io
