RADV Vulkan Driver Adds Option For Zeroing Out Video Memory
New to Mesa 20.1-devel is a new option for the Radeon Vulkan "RADV" driver to enable zeroing out video memory allocations.
This isn't a new concept with other graphics drivers offering similar functionality for zeroing out the vRAM either for security reasons or working around pesky game/app issues. For example, RadeonSI OpenGL zeros out the vRAM for Rocket League to workaround buggy behavior with that game. But zeroing out the video memory normally isn't done by default for all allocations due to performance reasons.
With the new flag to zero vRAM allocations for the RADV Vulkan driver it was done by Valve's Samuel Pitoiset. In this case he mentions it's in part for "future work."

Intel Gen12/Xe Graphics To Support 12-Bit HEVC/VP9 Decode
We are learning more about the media engine capabilities with the forthcoming Intel "Gen12" (Xe) Tiger Lake graphics.
The documentation for Intel's open-source media-driver that exposes VA-API capabilities on the Linux desktop was recently updated. That updated Intel VA-API Media Driver points to Intel Gen12 dropping VP8 video capabilities but expanding when it comes to 12-bit codec support.

Intel Sends Out Latest Patches For Mitigating Graphics Flaw On Ivybridge/Haswell
It has been one month and a few days since Intel first made public the need for graphics driver patching of Gen 7/7.5 graphics for older Ivybridge / Haswell hardware to fix a graphics hardware flaw. That vulnerability also affected the common Intel Gen9 graphics but there the mitigation was uneventful and quickly merged without causing any performance hit. But for Ivybridge/Haswell one month later the graphics driver mitigation for CVE-2019-14615 is still being addressed.
This vulnerability is also known as iGPU Leak by the researchers that discovered it but for the Gen7/Gen7.5 protection the mitigation has been particularly problematic. With the initial Gen7/Gen7.5 patches posted in mid-January there was a huge hit to the graphics performance while Intel worked towards no performance loss.

NVIDIA Posts Firmware Needed For Open-Source GeForce 16 Series Acceleration
As written about last week, in the works for the Linux 5.7 kernel this spring is open-source NVIDIA "Nouveau" acceleration for the GeForce 16 series. That code is currently sitting in the Nouveau development tree until landing in DRM-Next for Linux 5.7, but NVIDIA has now posted the necessary firmware binaries needed for enabling the hardware acceleration on these Turing GPUs.

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. |
