Intel will usually release new low power processors under 10W TDP every year, but that has not been the case for AMD, with the company releasing several 12-15W processors in the recent past like Ryzen Embedded V1000 series and the Ryzen 7 2700U processor I’m currently using my Ubuntu laptop. However, AMD has now announced two new A-series processors with a 6W TDP, namely A4-9120C and A6-9220C dual-core processors that specifically target Chromebooks. AMD A4-9120C key features: Processor – 2x CPU cores, 2x CPU threads @ 1.6 GHz / 2.4 GHz (Boost) Cache – 160KB L1 cache, 1MB L2 cache GPU – Radeon R4 graphics with 3x GPU Cores up to 600 MHz, support for H.26x, VP9 decode Memory – Single channel @ 1866 MHz Video Output – HDMI and DisplayPort Process – 28nm CMOS Package – FT4 TDP – 6 watts AMD A6-9220C key features: Processor – 2x CPU […]
Linux 4.20 Release – Main Changes, Arm and MIPS Architectures
After Greg K-H handling Linux 4.19 release, Linus Torvalds is back at the helm, and released Linux 4.20 just before Christmas: Let’s face it, last week wasn’t quite as quiet as I would have hoped for, but there really doesn’t seem to be any point to delay 4.20 because everybody is already taking a break. And it’s not like there are any known issues, it’s just that the shortlog below is a bit longer than I would have wished for. Nothing screams “oh, that’s scary”, though. And as part of the “everybody is already taking a break”, I can happily report that I already have quite a few early pull requests in my inbox. I encouraged people to get it over and done with, so that people can just relax over the year-end holidays. In fact, I probably won’t start pulling for a couple of days, but otherwise let’s just […]
Tranquil PC’s AMD Ryzen Embedded Mini PC Supports Up to 4 Displays
AMD Ryzen Embedded V1000 processor family was introduced last February, but if you’d wanted to buy a Ryzen Embedded mini PC today, you’ struggle to do so at least for a retail model. One option is to get an UDOO Bolt V3/V8 development board together its metal case and assemble the mini PC yourself. The solution was launched on Kickstarter however, and will only start shipping in December 2018 if everything goes according to plans. If you’d rather get a Ryzen Embedded mini PC a little earlier, Tranquil PC’s Mini Multi display PC may be an option with a choice of three Ryzen embedded V1000 processors, a fanless design, and support for up to 4 independent displays. Transquil PC’s mini multi-display PC Basic/Advanced/Advanced+ specifications: SoC Basic – AMD Ryzen Embedded V1202B, 2C/4T @ 2.3 / 3.2GHz, TDP: 12W-25W Advanced – AMD Ryzen Embedded V1605B, 4C/8T @ 2.3 / 3.6GHz, TDP: […]
Acer Aspire 3 A315-41G (AMD Ryzen 7 2700U) Laptop – Installing Ubuntu 18.04 and “Hidden” M.2 SSD Socket
Everyday I’m using a tower PC running Ubuntu 18.04 to take care of this blog, but when I travel it’s obviously not so convenient, so a few years ago I bought an Acer Aspire E5-421G laptop powered by an AMD A4-6210 processor with 4GB RAM, 512GB HDD, and a 14″ display. I installed Ubuntu on the laptop and it works, but with 4GB RAM, it’s not always usable while multitasking. For example I can run Thunderbird and Firefox, but if I ever make a Skype call for example, the system becomes unusable, and I have to close one of the programs. Tasks like video editing are also quite slow on the machine. So since I’m going to travel in a few weeks, I decided I needed a new laptop. My requirements were 8GB RAM, SSD and HDD support, a 15″ display, the ability to run Ubuntu 18.04, and possibly a […]
UDOO BOLT AMD Ryzen Embedded V1000 SBC Goes for $229 and Up (Crowdfunding)
While Intel has been outing low cost and low power processors with less than 10W TDP over the years with their Bay Trail, Cherry Trail, Braswell, Apollo Lake, and now Gemini Lake processors, AMD has not really ventured into the low power space, and the latest announcements about 10-12W processors was for their Embedded G-Series J Family, which I have not seen in many products. More recently, the company introduced Ryzen Embedded V1000 family of processors with 4 to 8 Zen cores, 4K support, 10 GbE interface, and more with a TDP of 12 to 25W for Ryzen Embedded V1202B & V1605B dual / quad core processors. The latest x86 UDOO board – dubbed UDOO BOLT – will be one of the rare AMD development boards available on the market with pricing starting at $229. Two versions of the board will be available: UDOO BOLT v3 with Ryzen Embedded V1202B, […]
Linux 4.16 Release – Main Changes, Arm and MIPS Architectures
Linus Torvalds has just released Linux 4.16: So the take from final week of the 4.16 release looks a lot like rc7, in that about half of it is networking. If it wasn’t for that, it would all be very small and calm. We had a number of fixes and cleanups elsewhere, but none of it made me go “uhhuh, better let this soak for another week”. And davem didn’t think the networking was a reason to delay the release, so I’m not. End result: 4.16 is out, and the merge window for 4.17 is open and I’ll start doing pull requests tomorrow. Outside of networking, most of the last week was various arch fixlets (powerpc, arm, x86, arm64), some driver fixes (mainly scsi and rdma) and misc other noise (documentation, vm, perf). The appended shortlog gives an overview of the details (again, this is only the small stuff in […]
Status of Embedded GPU Ecosystem – Linux/Mesa Upstream Support (ELC 2018 Video)
The Embedded Linux Confernce is on-going, and the Linux Foundation has been uploading videos about talks in a timely manner on YouTube. I checked out at RISC-V keynote yesterday, but today I’ve watched a talk by Robert Foss (his real name, not related to FOSS) from Collabora entitled “Progress in the Embedded GPU Ecosystem”, where he discusses open source software support in Linux/Mesa from companies and reverse-engineering support. The first part deals with the history of embedded GPU support, especially when it comes to company support. Intel was the first and offers very good support for their drivers, following by AMD who also is a good citizen. NVIDIA has the Nouveau driver but they did not really backed it up, and Tegra support is apparently sponsored by an aircraft supplier. Other companies have been slower to help, but Qualcomm has made progress since 2015 and now support all their hardware, […]
Vulkan 1.1 and SPIR-V 1.3 Specifications Released
The Khronos Group released Vulkan 1.0 specifications in 2015 as a successor of OpenGL ES, compatible with OpenGL ES 3.1 or greater capable GPU, and taking less CPU resources thank to – for instance – better use of multi-core processors with support for multiple command buffers that can be created in parallel. A year later, we saw Vulkan efficiency in a demo, since then most vendors have implemented a Vulkan driver for their compatible hardware across multiple operating systems, including Imagination Technologies which recently released Vulkan drivers for Linux. The Khronos Group has now released Vulkan 1.1 and the associated SPIR-V 1.3 language specifications. New functionalities in Vulkan 1.1: Protected Content – Restrict access or copying from resources used for rendering and display, secure playback and display of protected multimedia content Subgroup Operations – Efficient mechanisms that enable parallel shader invocations to communicate, wide variety of parallel computation models supported […]
