Is Intel Supporting Open-Source?
Intel has suddenly made some interesting hardware less interesting to open sourcers by insisting that its i915 DRM kernel graphics driver for upcoming Skylake and Broxton hardware demands some binary-only firmware blobs.
According to Phoronix these first i915 DRM firmware blobs are for Skylake and Broxton for the GuC and DMC.
DMC is the Display Microcontroller used by Skylake (Gen9) within the display engine to save and restore its state when entering into low-power states and then resuming. It saves and restores display registers across low-power states separate of the kernel.
Intel said that the firmware blobs are required by the DRM driver rather than being an optional add-on.
The license of these firmware blobs also indicate that redistribution is only allowed in binary form without modification. Beyond that, “no reverse engineering, decompilation, or dis-assembly of this software is permitted.”
Basically this will kill off any desire for Open Source enthusiasts to touch Skylake, although we doubt Intel will be too worried – they are a very nice couple. In any event AMD apparently uses something similar to protect bits of its operation.
Still Intel is shipping these firmware files early so everyone knows they are there.
Intel Talks More About Skylake
A new Intel roadmap suggests the first Broadwell LGA parts will launch in Q2, while Skylake-S parts will come in Q3.
The roadmap was published by PC Online and points to two Broadwell LGA launches this quarter – the Core i7-5775C and Core i5-5675C. These two parts will be joined by a total of four Skylake-S products in Q3, the Core i7-6700K, Core i7-6700, Core i5-6600K, Core i5-6600 and the Core i5-6500.
Both Skylake-S and Broadwell LGA will replace the current crop of Haswell parts, including Devil’s Canyon products. However, Broadwell LGA sits one tier above Skylake-S and Haswell-based products.
Starting in Q4, we should see more Broadwell LGA parts, but we don’t have any names yet. In the first quarter of 2016, we can also expect new Skylake-S parts.
Speaking of 2016, Intel plans to unleash the Broadwell-E in the first quarter of 2016. Little is known about Broadwell-E, but the new 14nm flagship is expected to sport eight cores. Clocks remain unknown, although the 14nm node promises substantial gains.
Will Intel Release Skylake This Year?
Intel has confirmed that it will release Core M processors this year based on its new Skylake chip design.
Intel CEO Brian Krzanich said at the Goldman Sachs Technology and Internet conference that the the new Core M chips are due in the second half of the year and will also extend battery life in tablets, hybrids, and laptop PCs.
The new chips will mean much thinner tablets and mobile PCs which will make Apple’s Air look decidedly portly. Intel’s Core M chips, introduced last year, are based on the Broadwell but the Skylake chips should also improve graphics and general application performance.
The Skylake chips will be able to run Windows 10, as well as Google’s Chrome and Android OSes, Krzanich said. But most existing Core M systems run Windows 8.1, and Intel has said device makers haven’t shown a lot of interest in other OSes. So most Skylake devices will probably run Windows 10. Chipzilla is expected to give more details about the new Core M chips in June at the Computex trade show in Taipei.
Skylake systems will also support the second generation of Intel’s RealSense 3D camera technology, which uses a depth sensor to create 3D scans of objects, and which can also be used for gesture and facial recognition. The hope is that the combination of Skylake and a new Windows operating system will give the PC industry a much needed boost.
In related news, Intel announced that socketed Broadwell processors will be available in time for Windows 10.
