Jailbreaking is not the problem. The problem is reverse engineering a large firmware that operates on HW they have no docs for and fixing the firmware (ie. doing it better that original manufacturer that has access to everything).

The job of firmware is so close to the hw that it's nearly impossible to decode. You need to decode a custom CPU instructions for a IP block the microcode is running on (it's custom, no ARM/RISC/MIPS..).

After that you have to decode what firmware actually does. It writes something to this.... What does it mean? It's completely opaque number written to a opaque memory... cache control? Delay?

And you do that why? So you can ship tinybox (i.e. cheap consumer GPU). Let's says you succeed. Do the same thing Next gen will be similar challenge, except firmware will be better locked, because AMD will want consumer HW to be segregated from data center GPU, the same way NVidia does.

The task itself is basically impossible and waste of time. There is the reason why NVidia driver driver for Linux was used basically only to install official driver.
