AMD, NVIDIA, and Intel updates continue to be common on Linux 5.19. Intel is beginning to slow down with its preparations for the Arc Alchemist and DG2 open-source drive, moving towards a more standard starting requirement for its dGPU. Recently, additions to non-core features for the ARC graphics devices have been announced. One of these new additions is vRAM Self-Refresh.
Intel Linux Driver is developing a new "vRAM Self Refresh" feature that will be included in Intel ARC graphics card support.
The addition of new vRAM SR support will help with D3cold and S0ix suspend modes for the entire system. Adding this new feature allows users to avoid expelling local memory objects to the system while exiting the D3cold power state. With a minimum adjustment from power consumption, the system can continue utilizing its dedicated video memory state by allowing it to remain minimally active.
After working on the company''s graphics cards, Intel''s Arc graphics card vRAM SR capability has arrived. The upgrade included recent IDs as well as support for Intel compute tasks, permitting the latest kernel to provide enhanced power management.
Intel''s ARC Graphics and its client graphics cards do not support D3Cold-VRSR mode, which offers the highest power save levels zero watts on the back of the vehicle, and increases latency upon departure.
The addition of vRAM SR capabilities and its advantage to the user''s system is based on BIOS support from Arc Alchemist''s DG2 graphics cards. However, the Linux kernel has yet to provide the same aid, which may result in it being fully supported for the open-source system.
The new Linux vRAM SR patch is currently available on Freedesktop. It is not anticipated to be included until the 5.20 to 6.0 kernel series.
