Intel Sends Linux Kernel Patches For VRR / Adaptive-Sync Enablement

For months now Intel's open-source Linux driver stack has been preparing for VRR support with Gen11/Gen12 graphics. We've seen user-space patches by Intel around VRR while now they are finally sending out their key Linux kernel driver patches with the i915 DRM code.

Linux Developers Discussing Possible Kernel Driver For Intel CPU Undervolting

While the Intel Extreme Tuning Utility (XTU) on Windows allows for undervolting laptop processors, currently on Linux there isn't any Intel-endorsed way for undervolting your CPU should you be interested in better thermal/power efficiency and other factors. But a hypothetical Linux kernel driver could be coming for filling such void.

Intel OpenGL/Vulkan Linux Drivers Strike Another Optimization For Tiger Lake

It was just on Monday that Intel's talented open-source developers merged a hefty Tiger Lake graphics optimization into the Mesa 20.3 code that for some games/software can be around ~11% faster thanks to greater caching. Just a day later another optimization has arrived for helping these latest-generation Intel graphics.

Intel Lands A Hefty Tiger Lake Graphics Optimization

From my Tiger Lake testing so far with the Core i7 1165G7, the "Gen12" Xe Graphics have been quite compelling with a very nice upgrade over Gen11 and especially obvious win over the very common still Gen9 graphics. With Mesa 20.3, another measurable performance is on the way for the Intel Vulkan driver with Tiger Lake.

Linux 5.10 Continues Maturing The USB4 Support

Earlier this year Linux 5.6 brought initial USB4 support by leveraging Intel's existing Thunderbolt kernel support for which the updated USB specification is based. Succeeding kernels have continued maturing this USB4 implementation and that has continued with Linux 5.10.

Intel Continues Prepping PKS For The Linux Kernel (Protection Keys for Supervisor)

Intel engineers continue working on "Protection Keys for Supervisor" support for the Linux kernel as a feature coming to a future generation of processors (presumably Sapphire Rapids). The initial users of this PKS support will be helping to protect persistent memory as well as adding safeguards to Trusted Keys within the Linux kernel.

The Linux Kernel Preparing To Take Advantage Of The Intel DSA / ENQCMD In Sapphire Rapids

Expected with next year's Intel Sapphire Rapids Xeon CPUs is the Intel DSA as the Data Streaming Accelerator for high performance data movement and transformation operations. Since the end of 2019 there have been Linux patches surfacing for bringing up the DSA support and now as we roll into 2021 the Linux kernel looks to begin making use of the new capabilities.

Intel's Patches Discussed For Exposing Hybrid CPU Topology Via Sysfs

Last week open-source developers at Intel began sending out Linux patches for supporting hybrid CPUs particularly ahead of 12th Gen "Alder Lake" coming to market with a mix of Golden Cove and Gracemont cores. Following that article last week, more patches hit the list in exposing the hybrid CPU topology to user-space.

Intel Adds Vulkan Transform Feedback For Aging Haswell Graphics

Due to DXVK recently beginning to require Vulkan Transform Feedback (VK_EXT_transform_feedback) for this Direct3D translation layer popular with Linux gamers, Intel open-source developers have gone back and now implemented transform feedback support in the Intel "ANV" driver for Haswell era "Gen 7" graphics.

Intel Prepares Linux Kernel Support For Advanced Matrix Extensions (AMX)

Following the announcement this summer of Intel Advanced Matrix Extensions (AMX) as an exciting feature coming to Sapphire Rapids Xeon CPUs next year, Intel's open-source engineers quickly began with patches to LLVM and GNU toolchain support for AMX. Now Intel engineers have sent out their patches in preparing the Linux kernel for AMX.

Intel Sends Out Latest DG1 Linux Patches But Won't Hit Until At Least The 5.11 Kernel

The sixth spin of Intel DG1 discrete graphics card patches have now been sent out for review, amounting to just about 700 lines of new driver code due to building off the existing DG1 work and more broadly the Gen12/Xe support that's been refined in mainline for months. With these patches it would appear the Intel DG1 is then in good shape under Linux but due to the timing is unlikely to be mainlined until a stable kernel release in early 2021.
