While he's answered some Linux questions, nothing has come out as a shocker. Some highlights:
- In response to one comment about the Vulkan Linux driver, he says it's coming "quite soon". But in response to another question about the Vulkan Linux driver, he reported, "The Vulkan Linux driver will be released soon." Then again, 'soon' and 'quite soon' is not really surprising. AMD has a working Vulkan Linux driver, they just haven't made it public yet.
- As I reported months ago, there still are no plans for AMD/RTG to support their Vulkan driver outside of the AMDGPU kernel realm. Their Vulkan driver is designed for AMDGPU. "Our Linux Vulkan drivers will only run on the amdgpu kernel driver. We have no plans, on Linux, to support Vulkan on any other driver stack."
- There's still no word when in the future the AMD Vulkan Linux driver will be open-sourced.
