Hi, I run out of module space because I have several big driver modules. I know I can strip the modules to decrease size but I need debug info now. The default size of module is 16MB and the size is statically defined in the header file. But a description for the module space size tell that it can be configurable at most 32MB. I have changed the module space size to 18MB and tested my platform. It have been looking good. I am not sure my patch is proper solution. Anyway, could I configure the module space size?
