Based on the linux SDK from board supplier, l developed some camera drivers. The SDK contains a dirty 4.1.15 kernel source, a uboot, anda prebuild rootfs archive. and the SDK is not controlled by a git, it's just an archive. > > Supposed now, I know how to submit a patch to which branch, is therep any tests need to be run before I submit? or is there a requirement for writing a test program to test my driver first? > > Could you give me some advices on what should I do next, or is l going toward a wrong direction? > > Thanks in advance, > > chen. > This course may be helpful for you to clear things up. https://training.linuxfoundation.org/training/a-beginners-guide-to-linux-kernel-development-lfd103 thanks, fox _______________________________________________ Kernelnewbies mailing list Kernelnewbies@xxxxxxxxxxxxxxxxx https://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
