RADV's Next-Gen Geometry Code Continues To Be Revised For Navi GPUs

So the old way with VK_EXT_transform_feedback will still work, but NGG could provide an alternative way to do it, but possibly won't in the future?

It's just a different hw path for doing streamout. The high level extensions don't care what path you use on the GPU.

Is NGG streamout affecting transform feedback, or it's not related?

Phoronix: RADV's Next-Gen Geometry Code Continues To Be Revised For Navi GPUs

The NGG (Next-Gen Geometry) support with Navi continues to be refined by the open-source AMD Linux graphics drivers with the RADV Vulkan driver seeing a fresh batch of fixes/clean-ups, inspired in part by the NGG code from the RadeonSI and AMDVLK drivers...
