Intel Working On VA-API AV1 Acceleration For FFmpeg

With Intel Xe LP / Tigerlake adding AV1 accelerated video decode, the Intel open-source developers are working to expose their AV1 hardware acceleration through the Video Acceleration API (VA-API) for usage by the likes of FFmpeg and other multimedia software.

New Intel Linux Graphics Driver Patches Aim For Better vGPU Performance

Proposed last year were a set of patches aiming to improve the Intel virtual GPU "vGPU" performance in para-virtualized cases by having optimizations around the shared memory region between the guest and Intel GVTg code. With optimizing the workload PV submission and PPGTT PV updates, the glxgears performance could improve by 30~50% while for large media/3D workloads was more around a 4% average improvement.

Intel Lands Adaptive-Sync/VRR Into Modesetting X.Org Driver

With Intel Gen11 graphics and newer supporting Adaptive-Sync / Variable Refresh Rate for minimizing tearing and stuttering, their open-source developers have now added the necessary bits to the generic xf86-video-modesetting X.Org driver for supporting the VRR functionality.

Intel Is Using IGC In Their Windows Drivers, Internal Prototype For Mesa
Intel Is Using IGC In Their Windows Drivers, Internal Prototype For Mesa

At Intel's Architecture Day this week the company was talking about work on their new Windows graphics driver that is being timed for Xe but supporting existing generations of hardware as well. One of the interesting takeaways was seeing the Windows driver is now using the open-source "IGC" back-end.

Intel Emmitsburg Support Begins Appearing In Linux 5.9

Not much is publicly known about Intel's Emmitsburg chipset. Prior to noticing some Linux patches recently referencing Intel Emmitsburg, the only other public mentions of it has been in the context of the Windows HWiNFO program mentioning it in their change-log. With Linux 5.9, Intel has begun adding Emmitsburg support.

Intel Workaround For Graphics Driver Regression: "The Platform Problem Going Crazy"

Sent out over the weekend was a patch series for the Intel Linux kernel graphics driver entitled "Time, where did it go?" This set of 42 patches aims to provide incremental improvements to the driver to offset a performance regression in Linux 5.7 that Intel hasn't been able to track down. This increased complication of the driver to offset the regression is now under the microscope.

Intel's Open-Source H.265/HEVC Encoder Sees First Release Of 2020

Intel's Scalable Video Technology team is known for their open-source video encoder work particularly on AV1 and VP9 formats, but they also continue to maintain a high performance H.265/HEVC encoder as well. Intel SVT-HEVC 1.5 was released on Monday as their first major update of the year.

Intel PMT Framework + Tiger Lake Telemetry Support Updated For Linux

Back in May I wrote about Intel working on Platform Monitoring Technology or hardware telemetry capabilities that are coming with Tiger Lake. The Linux support continues to be worked on for this "PMT" functionality although it looks like the work won't be ready in time for the imminent Linux 5.9 kernel merge window.

Linux Kernel Prepping To Make Use Of Intel's New SERIALIZE Instruction

As outlined a few months ago, Intel's future Sapphire Rapids and Alder Lake processors are set to add a SERIALIZE instruction. That SERIALIZE instruction ensures all flags/register/memory modifications are complete as well as draining all buffered writes to memory before the next instruction is executed. Linux is moving forward with preparing to make use of this new CPU instruction in its function for stopping speculative execution and prefetching of modified code.

Intel "Input Output Manager" Linux Driver Coming For Tiger Lake

While Intel's open-source engineers have been working on Tiger Lake enablement for Linux going back roughly a year with many kernel patches spanning the different areas over numerous kernel releases, which aligns with Intel's ongoing cadence of ensuring good Linux hardware support at launch even for consumer hardware, there have been a few stragglers in the Linux bring-up for Tiger Lake.

Intel Graphics Compiler Merges New Vector Compute Backend

While Intel on the hardware manufacturing side continues facing stiff challenges, on the open-source software side the company continues making legendary progress. Out in today's Intel Graphics Compiler and in turn Intel Compute Runtime releases as part of their GPGPU toolchain is the recent open-sourcing and integration of their Vector Compute back-end.
