At first glance, the ability of the kernel to write to unwritable userspace memory raises the question: to what degree can the CPU inhibit kernel memory access? The manual does indeed document control mechanisms that would seem to limit the kernel.
There seems to be at least one patent encumbering the PIO. As a matter of policy I do not read patents, thus I can’t opine as to whether or not the re-implementation infringes on any patents. However, this is signaling from the Raspberry Pi foundation that they do not welcome open source re-implementations of their block. They haven’t forced me to take down the source code for the block, but also, anyone attempting to use the reference code I’ve shared should be aware of this issue, and consider the risks of incorporating it into a product.
