I have written a device driver as a module and I am trying to load it into the
kernel with insmod.
When the module is compiled with a "Proprietary" license insmod fails with an
unknown symbol:
/mnt/code/gp/module> insmod gp.ko
gp: module license 'Proprietary' taints kernel.
gp: Unknown symbol __wake_up_sync
insmod: cannot insert `gp.ko': Unknown symbol in module (-1): No such file or
directory
However when the module is compiled with a "Dual BSD/GPL" license there is no
such problem:
/mnt/code/gp/module> insmod gp.ko
gp_init_hw
/gp_init_hw
Why is the proprietary license causing the Unknown symbol problem?
How can I fix it?
Thanks,
Chris
