    Phoronix: Linux 6.3 Brings Audio Support For Tesla's Full Self-Driving SoC

    Linux sound subsystem maintainer Takashi Iwai sent in the sound driver updates early for the Linux 6.3 cycle that is set to open following today's Linux 6.2 stable kernel release. Notable among the new audio hardware support is enabling Tesla's Full Self Driving "FSD" SoC support...

    They better be maintaining the code in the kernel. Its not a win for anyone unless this chip is available to the general public. This just helps Tesla offload some of its maintenance burden to other people.

      Honestly I don't see why any of it matters. If it's a chip only found in their vehicles, who cares about having drivers for it, regardless of whether it's open source, maintained, or even available at all? Like Michael said, it's not likely anyone is going to bother putting their own OS on it - in fact, I wouldn't be surprised if Tesla makes this hard to do, seeing as their source of profit is enabling features via software. As for making the chip available to the general public: unless this the only chip with a desirable feature compatible with Linux, what do we need it for?

        There is an obvious use for this unless Teslas run a Tivoized build of the kernel signed with a key not available to the public: hacking the Tesla to unlock "subscription" features without a subscription. This is needed for the entire car to unlock the battery and motor capabiliites. Self-driving on the other hand has major testing and liability issues, so modifying this would require that the driver never, ever rely on autopilot to avoid crashes. The level of attention needed (must never text or phone etc) probably makes self-driving useful only for navigation, so probably this should be disabled instead of unlocked on a hacked tesla.

        I have no subscriptions anywhere, and would refuse to buy a CPU, a car, or anything else with subscription-unlockable "features" without knowing in advance how to disable the subscription lock and enable the features. Certainly had GM tried to charge a subscription for say, heated seats in 1975 (same timeframe as the failed seatbelt interlock law), local garage mechanics would have undercut GM's subscriptions by jumpering around whatever black box was used to lock the seat heaters and install a wire to the battery, a fuse, and a switch.
