Sepolicy change for Pixel 7 / 7 Pro

[popogomo]

Google Camera's processing speed is very slow on Pixel 7 / 7 Pro devices, especially, Portrait processing that take over a minute to process. Many people reported this issue on GOS forums: https://discuss.grapheneos.org/d/1815-google-camera-very-slow-portrait-mode-processing/25

There was an sepolicy change needed for the Pixel 6 / 6 Pro in order to allow the camera software to access the DSP for accelerated image processing. Before that, Google Camera on Pixel 6 was slow too (please see here: https://issuetracker.google.com/issues/227166806#comment8

Was that change incorporated in the Pixel 7? Has it been properly validated that it doesn't need some tweaking for the minor differences? Thanks.

It works fine on the Pixel 6 without privileged hardware access. It will likely get fixed in Google Camera.

The sepolicy being referenced was intentionally removed by GrapheneOS to simply prevent it having privileged direct hardware access as attack surface reduction. Nothing is blocking it from using the hardware unprivileged at the cost of processing performance, it just does not have privileged direct access like it does on stock OS.

No plans to add this sepolicy back. Said issue will likely get fixed.

@Rubber-Duckie Full Tensor image processing functionality is available to Pixel Camera on GrapheneOS. Not sure why you're posting here, but you're completely wrong and misusing this as a discussion board.
