Intel Shares Highlights From Their 2019 Open-Source Technology Summit


INTEL --

Taking place back in May at the beautiful Skamania Lodge in Washington was Intel’s OSTS 2019 for their annual Open-Source Technology Summit that traditionally was internal-only but has begun opening up including allowing external participants this year. I was at OSTS 2019 and it’s by far my highlight of the year with many really great sessions and a lot of useful networking at the event. Intel’s open-source team has now shared some video recordings from this open-source/Linux event.

OSTS 2019 was a phenomenal event and I hope to be able to be back next year. This was a really great event with a lot of interesting and technical talks compared to so many other events these days often being filled with marketing fluff. Among the talks now available for your viewing pleasure are on Intel’s contributions to the Rust programming language, Optane DC Persistent Memory / new memory tiers on Linux, better kernel randomization, hardware crypto, and more. The only pity is that it took so long to get these interesting talks out there and hopefully they will be rounding it out with the other talks that took place at the event — there was a lot of interesting material and that’s even when unfortunately missing out on one of the days.

Those wanting to enjoy some nice technical presentations this weekend can find the current Intel OSTS 2019 videos via 01.org in a new blog post by Imad Sousou.


Microsoft, Intel and Others are Doubling Down on Open Source Linux Security


Hands Typing on Laptop Keyboard

Microsoft is continuing its broad ongoing push to contribute with open source projects, joining the newly created Confidential Computing Consortium, an initiative launched by The Linux Foundation which aims to provide better security for data which is actually in use by apps on a computer, or in the cloud (as opposed to at rest, or not being used).

Microsoft is far from alone in this endeavor, and is joined by Intel in the consortium, along with ARM, Baidu, Google Cloud, IBM, Red Hat and other tech giants. (Source: TechRadar)

Intel Submits Final Batch Of Graphics Driver Changes For Linux 5.4 – Growing Tiger Lake


INTEL --

After having been submitting various feature updates to DRM-Next the past few weeks of new graphics driver feature code to introduce in Linux 5.4, a final pull request was sent in today with the remaining feature work slated for this next version of the Linux kernel.

As added earlier to Linux 5.4, the big focus at this stage for the open-source Intel Linux developers is on bringing up the “Gen 12” graphics support for Tiger Lake. With the Icelake / Gen 11 graphics support now in good shape, the developers have already been busy plumbing Gen 12 graphics that are at least a year out from being available through retail channels. This final Intel DRM feature pull for Linux 5.4 includes:

– Continued work on bringing up Tigerlake Gen 12 graphics.

– DisplayPort Multi-Stream Transport (DP MST) fixes.

– GuC and HuC improvements.

– Gen11 graphics fixes and improvements around cache flushes.

– Missing Comet Lake PCI ID has been added.

– GPU reset fixes.

The complete list of changes for this pull request can be found via the mailing list.

The Linux 5.4 cycle will be formally starting in September while the Linux 5.4.0 stable release should be out in November.


Blender 2.81 To Feature Intel Open Image Denoise & Eevee Renderer Improvements


FREE SOFTWARE --

Blender 2.80 made its hugely anticipated debut just under one month ago while already Blender 2.81 is looking interesting and will hopefully be out in November.

Some of the early work for Blender 2.81 that’s now outlined on the in-progress 2.81 release page includes:

– Intel Open Image Denoise support was added for denoising renders. Intel’s been recently talking up the Open Image Denoise capabilities and nice to see it getting adoption in the Blender space as a new option. Those wanting to learn more about this denoising library geared for ray-tracing can do so via their GitHub site.

– Eevee as the new real-time render engine option of Blender 2.80 is being further enhanced with new features.

Open Image Denoise and Eevee improvements are what is most promising at the moment but some other work also includes:

– OpenVDB Voxel Remesh support to create a new quad mesh based on the volume of a mesh.

– Brush curve presets.

– WebM support.

– Support for writing alpha values in WebM and VP9.

More details via the in-progress release notes. It will be exciting to see what else lands in this open-source, cross-platform 3D modeling software ahead of the November update.


Linux 5.4 Set To Remove Intel XScale IOP33X/IOP13XX CPU Support


INTEL --

Linux 5.4 is set to remove the Intel IOP33X and IOP13XX series of processors that are part of the company’s former XScale product line for ARM-based CPUs.

The XScale IOP processors were intended for handling I/O offloading from the main device CPU. These sub-1.2GHz processors were part of Intel’s ARMv8.5-based XScale product portfolio. But with no apparent users of the Intel IOP33X/IOP13XX hardware left — at least anyone that would likely be riding new Linux kernel releases — that support is going to be removed later this year with the Linux 5.4 release.

Those XSeries lines are set to be removed as part of the ARM changes for this next kernel version. The commit explains:

There are three families of IOP machines we support in Linux: iop32x (which includes EP80219), iop33x and iop13xx (aka IOP34x aka WP8134x).

All products we support in the kernel are based on the first of these, iop32x, the other families only ever supported the Intel reference boards but no actual machine anyone could ever buy.

While one could clearly make them all three work in a single kernel with some work, this takes the easy way out, removing the later two platforms entirely, under the assumption that there are no remaining users.

Earlier versions of OpenWRT and Debian both had support for iop32x but not the others, and they both dropped iop32x as well in their 2015 releases.
