I have worked with Lauterbach TRACE32. It was sometimes helpful to see D cache lines of DMA buffers when you look for e.g. corrupted RX/TX ethernet packets etc. I didn't need to use TLB inspection yet. TRACE32 has a good deal of integration in their debug view, e.g. you can see in a source browser during debugging which variables are in the data cache etc, very helpful for optimizing inner loops. I don't know if GDB has any support for that level of introspection, but I doubt it.
