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.

A few days back we wrote of Intel's ISPC compiler landing GPU code generation support for their UHD/Iris/Xe Graphics from Gen9 Skylake and beyond. Following that code being merged, ISPC 1.14.0 was quickly tagged.

Besides the code itself to Intel's oneAPI being open-source, the company is being surprisingly open about its support even for areas of usage outside of x86_64 CPUs.

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.

Intel's open-source ISPC (the Intel SPMD Program Compiler) now has preliminary support for code generation targeting their GPUs.

Building off the recently mainlined Intel work on split lock detection, Intel engineers have now been extending that with bus lock detection support.

For those using the Intel ICE Linux network driver that is used for the likes of the E800 series, it's now going to be easier updating the device firmware from Linux.

Intel has been preparing "Power Limit4" support for their Linux PowerCap driver that is being rolled out for the forthcoming Tiger Lake SoCs.

Following last week's public disclosure that Intel is running six to twelve months behind on their 7nm production, Intel this evening announced a set of leadership changes to move the company forward.

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.

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.

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.

Jiving with all the recent rumors, the latest Linux kernel patch work further spells out clearly that Intel Alder Lake will feature a hybrid core design akin to Arm's big.LITTLE architecture.

Over the past several months there has been work on Intel's Linux kernel graphics driver for async page-flipping to yield better performance. That work was revised against today for hopefully making it into a kernel release in the near future albeit too late for Linux 5.9 but regardless nice to see this work moving forward.

Intel's IWD wireless daemon for Linux systems has been seeing work in recent days on integration around WiFi Display support, a.k.a. WFD / Miracast.

While we remain eager to find out more about (and benchmark) Intel Gen12 graphics in Tiger Lake and Xe discrete graphics with this generation bringing the biggest changes to the ISA since i965, Linux patches and bug reports do continue offering new tid-bits of information on Gen12.

As we have been anticipating for weeks, initial (but still early) enablement of the Intel DG1 graphics card on their open-source driver stack will indeed be sent in for the upcoming Linux 5.9 cycle and is currently being queued in the DRM-Next repository.

Longtime open-source Intel Linux kernel graphics driver developer Chris Wilson has out a big new set of patches.

Intel's Elkhart Lake as the Denverton successor for ultra-low power use-cases has a few more device IDs now in place for the Gen11 graphics.

While being very eager to learn more about Intel next-gen Ice Lake Xeon processors as their move in the server space finally from 14nm to 10nm+, we continue to learn new tid-bits from the open-source Linux kernel activity.

The patches talked about last month for a new "energy efficiency" tunable for the Intel P-State driver for Kabylake / Coffeelake CPUs is set to go into Linux 5.9 for those wanting to increase the energy efficiency of these CPUs on Linux albeit with reduced performance.

Intel's open-source compiler engineers have been quite timely in getting the Advanced Matrix Extensions (AMX) support out in the relevant components since Intel formally outlined AMX in last month's programming reference manual.

Recently there have been a lot of open-source Linux patches flowing concerning Intel's bring-up of their DG1 discrete graphics card for developers. That work continued this week with the latest patches in wiring up LMEM support.

Linux creator Linus Torvalds had some choice words today on Advanced Vector Extensions 512 (AVX-512) found on select Intel processors.

Landing in the GNU Compiler Collection 11 (GCC 11) codebase this morning is the Sapphire Rapids and Alder Lake enablement.

Intel has shipped its second quarter open-source Media Driver release that provides accelerated video encoding/decoding capabilities on Linux systems.

On top of Intel Gen12/Xe Graphics bringing other media engine improvements and much better 3D graphics support, another exciting element of the next-generation Intel graphics is now confirmed: GPU-accelerated AV1 video decoding!

Intel has today made public more details on their next-generation Thunderbolt connectivity that brings more features while offering USB4 specification compliance. Thunderbolt 4 is coming with forthcoming Tiger Lake laptops.

Intel CPUs have long supported LBR for last branch records as a means of recording the branches to which software has taken along with exposing other control flow information. This has relied upon model-specific registers while with future Intel CPUs this is being folded into a more universal CPU architectural feature. Support for Intel "Arch LBR" is set to come later this year with the Linux 5.9 kernel.

Building upon Intel working on GNU toolchain support for AMX, the newly-detailed Advanced Matrix Extensions being introduced next year with "Sapphire Rapids" Xeon CPUs, the GCC compiler support has been sent out in patch form.
