    AMD PR already contacted me to let me know they're working on an answer.

        I hoped they were working on a solution instead of an answer: migrating all linux fglrx developers to radeon..

          Stallman was right

          What if they have backdoors in the Firmware too? We need open devices, it's sad to see http://www.phoronix.com/scan.php?pag...tem&px=MTQ4MDU failed

            Not only does this make the Catalyst driver suspect, it also casts a shadow over the open-source driver. If you remember, AMD pushed *hard* to use a firmware blob in Radeon, instead of the clean-room approach of RadeonHD.

            I used to think it didn't matter, but apparently I was naive. Luc Verhaegen was right all along.
            I can confirm the existence:
            Code:
            $ nm /usr/lib/libamdocl64.so | grep -i backdoor
            000000000074dcf0 t osTestBackdoorATI
            Yet, who would lable a symbol for some backdoor "backdor"? This makes it to my list of the dumbest accusations I heard so far

              It's harder to put backdoors in the firmware and easier to spot compared to a whole driver. FOSS hardware it the next step of course but in the meantime I'm fine with FOSS drivers

                Probably a dumb name for some debug function.

                  Put my bet down for 'not actually a backdoor; humorously-named test function'.

                  If you were going to put a top-secret NSA backdoor into your driver, why would you give it such an obvious name? You'd call it osDefinitelyNotABackdoor instead, right?!

                    Just more Nvidia FUD.

                      AMD does make cpu's and desktop motherboard chipsets. ATI was acquired by AMD. I own a NVidia graphics card and that uses the proprietary Nvidia drivers.

                      I was considering moving away from Intel due to their allegiance to Microsoft.
