Intel's Vulkan Driver Squeezes Another Optimization Into Mesa 20.0
Patches written two months ago for Intel's ANV open-source Vulkan driver have now been merged ahead of the imminent Mesa 20.0 feature freeze and branching.
The work worth mentioning is allowing HiZ in read-only depth layouts. "These layouts don't mean "sampled" they mean the same thing as DEPTH_STENCIL_OPTIMAL only the client promises to not write the depth or stencil buffer as indicated. Since HiZ depth testing is much faster than non-HiZ depth testing, we really don't want to disable HiZ for these."

RadeonSI Introduces A Live Shader Cache With Mesa 20.0
In addition to the AMD RadeonSI Gallium3D driver's on-disk shader cache and in-memory shader cache there is now a "live shader cache" to help with deduplication of compiled shader objects.
AMD's Marek Olšák landed this live shader cache on Friday. The introduction of this new caching level stems from the behavior of when games concert separate D3D shaders into linked GLSL shaders, the same vertex shader is often used with many different fragment shaders. In introducing this live shader cache of the compiled shader objects, for affected titles there should now be fewer resident shaders and fewer shader state changes.

Samsung, Red Hat to Work on Linux Drivers for Future TechThe metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. |
