Xav, thanks for your reminder. Actually our law leam has already checked the license. As Dave said, the DRM kernel driver is all MIT-licensed and we will be free to use them. When the drm uses linux kernel function calls, we will use freebsd(none-GPL) equivalent to replace. Dave, by the way, I want to ask you about some exceptions in DRM. you know in some files(i.e. drm_fb_helper.c), it includes MODULE_LICENSE("GPL and additional rights"). Does it mean it is GPL licensed? Is it free to use this file?
Those files are derived from the kernel fb layer so are not drm core infrastructure.
They make no sense on other OSes, since they don't have the same kernel fb layer.
Yup. CE does have fb layer, when I did the modeset part, there is no fb layer in it and none of fb functions will be used in our driver. So I understand that you said those files are derived from the kernel fb layer. So what's the relastionship between drm fb helper and real kernel fb ?
Dave.
