Phoronix: Intel Vulkan Driver Implements A Transfer Queue For DG2/Alchemist GPUs

In addition to Vulkan sparse support that works with the existing i915 kernel driver, another exciting open-source Intel Vulkan driver development this week is landing a transfer queue implementation for DG2/Alchemist GPUs. This in turn can help with hybrid graphics systems and other situations...

Does anyone care to explain in which setups is this patch beneficial?

Is it on regular PRIME setups where the display is connected to the igpu and vulkan app is running on dgpu (alchemist) or with Reverse PRIME (the othe way around)? https://wiki.archlinux.org/title/PRIME

Dedicated transfer queues can asynchronously move data from/to the GPU in the background without disrupting the main rendering task. This is similar to AMDGPU's SDMA engine.
