Linux 5.19 kernel continues to see plenty of AMD, NVIDIA, and Intel updates. Intel is starting to slow down with its preparations for the company's Arc Alchemist and DG2 open-source drive support, moving towards a more standard starting requirement for their dGPU. Recently, additions to non-core features for the ARC graphics devices have appeared. One of these newest inclusions is vRAM Self-Refresh, or vRAM SR.

The new vRAM SR support will help with D3cold and S0ix suspend modes for the complete system. Adding this new feature allows users to bypass expelling local memory objects to the system while in an energy-efficient state. vRAM SR provides for the retention of devoted video memory context to become refreshed while exiting the D3cold power state. Users can expect lower latency levels when recovering from energy-efficient conditions with a minimum adjustment from power consumption. The system can continue utilizing its devoted video memory state by allowing it to remain minimally active.
