Linux 6.6 LTS release – Highlights, Arm, RISC-V and MIPS architectures

Linux 6.6 release

The Linux 6.6 release has just been announced by Linus Torvalds on the Linux Kernel Mailing List (LKML): So this last week has been pretty calm, and I have absolutely no excuses to delay the v6.6 release any more, so here it is. There’s a random smattering of fixes all over, and apart from some bigger fixes to the r8152 driver, it’s all fairly small. Below is the shortlog for last week for anybody who really wants to get a flavor of the details. It’s short enough to scroll through. This obviously means that the merge window for 6.7 opens tomorrow, and I appreciate how many early pull requests I have lined up, with 40+ ready to go. That will make it a bit easier for me to deal with it, since I’ll be on the road for the first week of the merge window. Linus About two months ago, […]

Thunderbolt 5 to deliver up to 120 Gbps bandwidth, support multiple 8K monitors

Thunderbolt 5 capabilities

Intel has just announced Thunderbolt 5 and demonstrated it with a prototype laptop and dock (see the video embedded at the end of this post) with up to 120 Gbps bandwidth when using “Bandwidth Boost”. Thunderbolt 5 will deliver 80 gigabits per second (Gbps) of bi-directional bandwidth and the top 120 Gbps bandwidth is achieved through “Bandwidth Boost” to support multiple 8K monitors, which means three times the bandwidth of Thunderbolt 4 topping at 40 Gbps. Thunderbolt 5 builds upon Thunderbolt 4 with several improvements and features: Two times the total bi-directional bandwidth, and up to three times (120 Gbps) for video-intensive usage Double the PCI Express data throughput for faster storage and external graphics. Compatible with USB4 V2, DisplayPort 2.1, and PCI Express Gen 4 Double the bandwidth of Thunderbolt Networking for high-speed PC-to-PC connections. PAM-3 signaling technology to deliver increases in performance with today’s printed circuit boards, connectors, […]

Intel Downfall (Gather Data Sampling) vulnerability impacts AVX2/AVX-512 workloads

Intel Downfall

After vulnerabilities like Spectre and Meltdown were discovered in 2018, Intel processors have more vulnerabilities with the Downfall attacks that target the Gather instruction part of AVX2/AVX-512 and impact 6th generation Skylake up to 11th generation Tiger Lake processors introduced as far back as 2014. It does not affect more recent processors, and as somebody who has just purchased a laptop based on a 13th Raptor Lake processor, I guess I can breathe a sigh of relief until the next vulnerability is discovered, but people using hardware with older Intel processors will have to update the OS and suffer from a performance impact, at least for tasks leveraging AVX2 or AVX-512. The website about the Downfall vulnerability explains: Downfall attacks targets a critical weakness found in billions of modern processors used in personal and cloud computers. This vulnerability, identified as CVE-2022-40982, enables a user to access and steal data from […]

Intel AVX10.2 ISA to enable AVX-512 capabilities on E-cores

Intel AVX10

Intel AVX10 SIMD instructions will succeed AVX-512 instructions with AVX10.2 adding support for Intel E-cores to bring multimedia and AI acceleration to low-power cores, while the earlier AVX10.1 will add version-base enumeration and make 512-bit instructions optional, but still only work on Intel (Xeon) P-cores. The new Intel Advanced Vector Extensions 10 (AVX10) architecture was unveiled in an update to the Advanced Performance Extensions (Intel APX) bringing AVR-512-like support to new hybrid processors with P-cores and E-cores, as well as potentially their entry-level versions with E-cores only. Intel explains the new SIMD architecture includes all the capabilities and features of the Intel AVX-512 ISA, both for processors that feature 256-bit maximum vector register sizes, as well as for processors that feature 512-bit vector registers. The AVX10 ISA adds a new version-based enumeration scheme that reduces the number of CPUID feature flags needing to be checked for feature support. As mentioned […]

Intel kills its NUC business

Intel kills NUC business

Intel has just decided to shut down its Next Unit of Compute (NUC) business selling mini PC, PC, boards, and modules directly to customers, as the company told partners they will stop direct investment into that part of their business. We first wrote about Intel NUC in 2014, but the company’s first NUC was launched in 2013, and I can only imagine Intel decided to kill the NUC business in order to focus on its core business which is to sell processors. They won’t directly compete against their customers anymore, although it’s unclear if this was part of the decision… I have mostly read praises about the NUC family over the years, but I’ve had a mixed experience myself. One family member asked for a reliable mini PC, so I recommended a Core-i5 NUC and while it mostly worked fine, we had to purchase a separate USB WiFI dongle as […]

MIPI CSI camera works with Intel Atom x7000, Processor, and Core i3 Alder Lake-N processors

Alder Lake-N Customer Reference Board MIPI CSI camera

Most Intel processors do not come with a MIPI CSI camera, but some Alder Lake-N processors do, and Leopard Imaging has designed the LI-ADL-ADP-IMX415-MIPI-081H MIPI CSI camera module that is compatible with the Intel ADL-N CRB (Alder Lake-N Customer Reference Board) and custom Alder Lake-N boards equipped with a compatible MIPI CSI connector. The 13MP camera supports resolutions up to 3864 x 2176 and works with boards and embedded systems based on Intel Atom processors x7000E Series, Intel Core i3-N processors, and Intel Processors N-Series processors.

Intel kills PathFinder IDE for RISC-V processors

Intel PathFinder Discontinued

Intel has just discontinued PathFinder Eclipse-based development environment for RISC-V processors with the website now reading: We regret to inform you that Intel is discontinuing the Intel Pathfinder for RISC-V program effective immediately. Since Intel will not be providing any additional releases or bug fixes, we encourage you to promptly transition to third-party RISC-V software tools that best meet your development needs. PathFinder was a pre-silicon open-source development environment with support for vairous RISC-V cores, a set of other IP’s, multiple operating systems, and toolchains. It allowed designers to create RISC-V SoCs to and run them on FPGA platforms such as the Terasic developer kit or Startix-10 GX evaluation kit. PathFinder appears to just be one of the casualties after Intel reported a loss for Q4 2022, and announced it will lose even more in Q1 2023 with Tom’s Hardware also highlighting Intel would stop investing in new products for […]
