Are there actually open ARM CPUs? My very vague understanding was that ARM claims that their ISA cannot be implemented without infringing some patents on some instruction encoding tricks they hold.
- turblety 9y agoYeah you're right. Basically my concern is having backdoors written into driver firmware that can not be removed. For example Intel's ME [1], AMD's PSP [2], Samsung's BL1 bootloader, etc. For me personally I don't mind using hardware that has patents and copyright, so long as when I buy it I'm free to do what I want with it without undue surveillance from corporations or government. So yes, I guess the hardware isn't open, but all the software/firmware on can be (for example the RK3288 [3]) (of course with the exception of the GPU). 1. https://libreboot.org/faq.html#intelme https://libreboot.org/faq.html#intelme 2. https://libreboot.org/faq.html#amd https://libreboot.org/faq.html#amd 3. https://libreboot.org/docs/hardware/c201.html https://libreboot.org/docs/hardware/c201.html
