The first step in doing this is making it so that we can read the current state of IORs from nvkm in DRM, so that we can fill in said into into the atomic state. We do this by introducing an INHERIT ioctl to nvkm/nvif. This is basically another form of ACQUIRE, except that it will only acquire the given output path for userspace if it's already set up in hardware. This way, we can go through and probe each outp object we have in DRM in order to figure out the current hardware state of each one. If the outp isn't in use, it simply returns -ENODEV. This is also part of the work that will be required for implementing GSP support for display. While the GSP should mostly work without this commit, this commit should fix some edge case bugs that can occur on initial driver load. This also paves the way for some of the initial groundwork for fastboot support.
