Hello,
I have a PCI-Express video capture card that has a proprietary driver for Linux.
I have some experience with programming in C, and so I would like to start a hobby project to develop a free/libre driver for this device for Linux.
Of course I don’t have access to any documentation about how to communicate with this device, so I think I will need to reverse-engineer the way the existing driver communicates with the hardware. How could I achieve this ?
Also, the long term goal of this project would be to have this driver merged into mainline, so what is allowed or not while doing this to avoid problematic legal ramifications ?
Thank you for your help.
Best regards.
Tomek Lecocq

Please do not ask programmers legal questions, would you ask your
medical doctor kernel programming questions?
If you have legal questions about doing this sort of thing, please
contact a lawyer, don't trust random people on a public mailing list on
the internet for advice.
good luck!
