The x86 platform driver updates were merged this week into the Linux 6.3 kernel and include the initial Intel TPMI integration along with several other driver changes.

Intel's open-source Compute-Runtime stack for OpenCL and oneAPI Level Zero support along with the Intel Graphics Compiler (IGC) had been on a rhythm of typically seeing new tagged releases every week or two... Quite nice and living up to the open-source development philosophy of "release early, release often." That persisted for a long time until Q4'22 when the releases became less frequent. In early December though the release train stopped and not until this morning has there been a new release of the Compute-Runtime and IGC.

Intel Trust Domain Extensions (TDX) is one of the new features with 4th Gen Xeon Scalable "Sapphire Rapids" processors but is limited this generation to deployment by a few select cloud partners. For Linux 6.3 this feature for hardware-isolated virtual machines is continuing to be further refined.

While the Linux 6.3 merge window has just begun, what you won't find in this next kernel version is the Intel Xe DRM driver as the new kernel graphics driver being worked on by the company for their modern integrated and discrete graphics processors.

Intel this weekend submitted their Linux device driver patches for review concerning their La Jolla Cove Adapter (LJCA) hardware.

Yesterday I provided a glimpse of the AMD changes coming to Linux 6.3 while today the table is turned and looking at the Intel changes on deck for this next Linux kernel version.

It's not exactly the most applicable configuration for hardware and software, but a 24% performance boost is nothing to sneeze at... A 24% performance boost when for an open-source game when using the Intel ANV Vulkan driver with older Gen8 Broadwell or Gen9 Skylake graphics while using the Zink layer.

As 718,996 lines of newly open-sourced code, Intel recently began opening up their previously proprietary CPU-based OpenCL run-time.

Intel recently published an open-source C++ header file library for high performance SIMD-based sorting, which initially is focused on providing a lightning fast AVX-512 quicksort implementation. As of today that code has been merged to Numpy and is providing some 10~17x speed-ups.

Patch Tuesday brought AMD disclosing a Ryzen Master security issue on Windows and the Cross-Thread Return Address Predictions bug requiring new handling by Linux's KVM. Over on the Intel side they have disclosed nearly three dozen new issues and as a result also published new Linux CPU microcode files for their recent processors to address the disclosures.

An Intel engineer has implemented compute-based transcoding support to the DXT5 texture format as part of S3TC texture compression. This new path yields a 56% decrease in upload time for a texture upload micro-benchmark when tested on an Intel Ice Lake system with the Iris Gallium3D driver.

One of the open-source Intel Linux graphics driver milestones we have to look forward to this year is the introduction of the new "Xe" kernel graphics driver to effectively succeed the existing "i915" Direct Rendering Manager driver for recent generations of Intel graphics. More prep code was merged this week to Mesa's Intel "ANV" Vulkan driver in preparing to be able to make use of that new kernel mode driver once its upstreamed into the Linux kernel.

Following last week's article about Linux developers eyeing a new "DOITM" security mitigation for latest Intel CPUs based on guidance from Intel around Data Operand Independent Timing (DOIT) instructions and then it coming to light that the DOIT mode shouldn't always be on, a lengthier statement from one of Intel's Linux engineers has been published summing up the current beliefs and Linux kernel possibilities around DOIT(M).

Intel engineers this week published new Linux open-source driver code for TPMI, the Topology Aware Register and PM Capsule Interface. Intel TPMI for seemingly future processors will allow for more streamlined power management handling and other enhancements over the way the Intel power management drivers currently function.

Last week I wrote about Linux developers evaluating a new "DOITM" security mitigation for the latest Intel CPUs. While the cost for now of engaging the Data Operand Independent Timing Mode (DOITM) functionality is minimal, following internal Intel engineering discussions it looks like the Linux kernel patches will need to be re-worked with this functionality not intended to always be enabled.
