Raspberry Pi 4 GPU Driver Gets Vulkan 1.2 Support

Arthur T Knackerbracket has processed the following story:

The Raspberry Pi 4's open-source Vulkan driver for its Broadcom GPUs has now achieved conformance with the Vulkan API 1.2 standard. 

Vulkan is a graphics and compute API that provides high-efficiency, cross-platform access to modern GPUs, and aims to provide graphics developers with new ways to get the best performance out of hardware. Raspberry Pi founder Eben Upton described the driver as a 'much requested feature' when work started on the project a couple of years ago.

[...] The new driver will come to future Raspberry Pi OS updates as the Vulkan 1.2 updates have been merged into the upstream V3DV Mesa driver. As with Vulkan 1.0 conformance Raspberry Pi gained over a year ago, Vulkan 1.2 API conformance gives app developers better access to Pi's Broadcom VideoCore 3d GPU. 

The best examples of "real world" applications for Vulkan on Raspberry Pi today are games running on Android/Lineage, Upton said.

Raspberry Pi has partnered with consultancy Igalia to develop Vulkan drivers for Pi 4's GPU.

    1.8 GHz is now the standard for new boards with the latest RPi OS, although the heatsink in the Pi 400 is going to better than most other cases.

    Users with recent Raspberry Pi 4 devices will find that their default turbo-mode clock has increased from 1.5GHz to the 1.8GHz used on Raspberry Pi 400. “Recent” in this case means any 8GB Raspberry Pi 4, or a 2GB or 4GB board with the extra components circled in the image below. This is the dedicated switch-mode power supply (“switcher”) for the SoC core voltage rail, and was introduced when we shuffled the allocation of switchers to rails to support 8GB.

    Through extensive testing on the production line, we have qualified an operating voltage for 1.8GHz, and satisfied ourselves that the new switcher is able to supply enough current to run even the heaviest workloads at that speed.

    Overclocking to 2.0-2.1 GHz with passive cooling is trivial now.
