I'm trying to compare two allocation schemes in my Metal renderer:
- allocate separate MTLBuffers out of an MTLHeap
- allocate one full-size MTLBuffer from an MTLHeap, then doing my own suballocating and tracking the offsets
The first is straightforward and I get a nice overview of everything in the Xcode Metal debugger. For the second, I use addDebugMarker:range: to label each of my custom buffers. I have looked everywhere and can't see where my debug labels are supposed to appear in the debugger. The memory overview only shows the one MTLBuffer that spans the entire MTLHeap. My renderpass works as expected, but the command list and resource views only reference the single MTLBuffer as opposed to the tagged ranges.
What am I missing?
