To ease readability, use switch to set unique_id as supported for the supported IP_VERSIONs, and set it to unsupported by default for all other ASICs.

2022-01-27drm/amdgpu/UAPI: add new CTX OP to get/set stable pstatesAlex Deucher1-0/+5
Add a new CTX ioctl operation to set stable pstates for profiling. When creating traces for tools like RGP or using SPM or doing performance profiling, it's required to enable a special stable profiling power state on the GPU. These profiling states set fixed clocks and disable certain other power features like powergating which may impact the results. Historically, these profiling pstates were enabled via sysfs, but this adds an interface to enable it via the CTX ioctl from the application. Since the power state is global only one application can set it at a time, so if multiple applications try and use it only the first will get it, the ioctl will return -EBUSY for others. The sysfs interface will override whatever has been set by this interface.
