    Phoronix: Sound Open Firmware 2.3 Released With Support For AMD Rembrandt, Intel Raptor Lake

    Sound Open Firmware is what started as an open-source Intel effort to push towards more open sound/DSP firmware and has grown since that point into a Linux Foundation project also supported by other vendors like Mediatek, AMD, Realtek, and others. Sound Open Firmware 2.3 was released on Tuesday as the latest advancement for this open-source audio DSP firmware stack...

    Sound Open Firmware seems amazing, could something similar be done for graphics and network?
    If so, then I wish Intel would create Graphics Open Firmware and Network Open Firmware too!

      Isn't that basically what a GPU already is? You can do pretty much anything you want in the shaders.

        Well, we are obviously talking GPU firmware and microcode here, just like for this audio DSP, ... AKA the (un)popular and randomly changing binary blobs, ... ;-)

          Well, it's a little bit different. The GPU firmware is basically just a front end to schedule user jobs on the shaders. The shaders themselves are the processing engines where your kernels run. In the case of these sound chips, the firmware is what runs on the DSP so the DSP is more equivalent to the shader functionality-wise. The GPU firmware is more akin to the fixed function DMA engines and i2s interfaces on the sound chip which feed the DSP.

            does not change that it could be an open graphics firmware projects, ... with open scheduling, memory management, job and reclocking management. I'm sure the audio boys and girls also previously said: "why open source this just DSP firmware", ... ¯\_(ツ)_/¯
