This patch series lets DRM fdinfo stats functions display an additional tag that will reflect the amount of memory internal BOs of a DRM driver take up. The rationale for this is that some drivers, like Panthor, need quite a bit of memory for things like queue ring buffers or tiler heap chunks, and these will vary dynamically as new scheduler groups, queues or heap chunks are created by one or more render contexts. Because these are tied to an open DRM file that represents an ongoing render context, then it makes sense to provide users with this information in the DRM file fdinfo descriptor, even though they would never be exposed to UM through a handle. These two patches were originally part of a wider series, but broke it down into two different submissions for ease of discussion. The previous debate can be found at [1], in its latest two patches.
