For those curious how the performance is impacted for the 2012 "Ivy Bridge" Retina MacBook Pro when upgrading to OS X 10.9 Mavericks, here's some fresh open-source benchmarks comparing the 10.8.5 and 10.9.0 releases for this Core i7 laptop with Intel HD 4000 and NVIDIA GeForce graphics.
There's many exciting Linux 3.13 kernel features already, but we have another one to talk about today. In the input subsystem update for 3.13, support for the Neonode zForce has been added, an interesting touch-screen technology based on infrared light fields.
Canonical with their Ubuntu Touch initiative isn't the only project that's failed to deliver as of yet with a successful non-Android Linux tablet.
An IBM Linux Technology Center has shared that enabling experimental memory power management within the Linux kernel has dropped one of their test system's power consumption by about 2.6% but it's likely even more with experimental hardware.
While 64-bit ARM hardware isn't publicly out yet, the AArch64/ARM64 support continues to be improved within the Linux kernel and readying for the onslaught of new, faster ARM devices to appear in 2014.
Takashi Iwai sent in the sound driver audio pull for the Linux 3.13 kernel on Sunday. This update features HDMI audio improvements for Intel and AMD hardware, among other Linux sound improvements.
Intel GMA500 DRM kernel graphics driver patches were published this morning for supporting the Atom-powered Minnowboard.
David Herrmann, the open-source Linux graphics developer of fame for working to kill CONFIG_VT via work on numerous projects and many other open-source contributions, has started a new open-source project. Herrmann's latest initiative is OpenWFD, an open-source implementation of the WiFi Display Standard / Miracast.
It looks like the latest attempt at producing an open-source graphics processor down to the hardware level -- an open-source FPGA GPU design -- will fail and not come to fruition with its targeted Kickstarter campaign.
It's been a long time since hearing anything out of the OpenMoko camp, but Golden Delicious that worked on the GTA04 / OpenPhoneux is now trying for a new initiative. The company wants to develop the Neo900, which would be based around the once-popular Nokia N900 case but utilize upgraded internal components.
The latest company now offering low-cost ARM development boards for pushing their platform to ARM Linux and Android developers is VIA Technologies. VIA claims their new Springboard platform is "the fast path from prototype to production" and only costs $100 USD, but the specifications aren't all that impressive.
After writing earlier this month that UPower 1.0 is nearing, UPower 0.99.0 has been released this morning.
Last week I bought the ASUS Transformer Book T100TA, which is one of the first Intel "Bay Trail" devices in the United States. At a cost of $399 USD, it isn't as cheap as some Bay Trail devices talked up by Intel, but I was eager to see how the "Valley View" graphics would perform and all-around how this Atom SoC would run under Linux. Sadly, the ASUS T100TA appears to be a crap wreck at this point for running Linux.
Coming as soon as later today will be benchmark results comparing the performance of Microsoft Windows 8.1 against Linux in various graphics-focused workloads for Intel, AMD, and NVIDIA hardware.
Yesterday I began posting quad-core ARM Cortex-A15 SoC benchmarks using an ODRIOID-XU with Exynos 5 Octa, which has a quad-core Cortex-A15 paired with the "little" quad-core Cortex-A7. In this article are more benchmarks of the Samsung Exynos 5 Octa compared to various AMD and Intel CPUs.
When the first ARM Cortex-A15 SoCs started rolling out in devices I found the dual-core A15 performance to be crazy fast for ARM and still find the Cortex-A15 performance to be great for low-power devices. Now, however, there's quad-core Cortex-A15 SoCs and even with the big.LITTLE architecture these four A15 cores can be paired with four A7 cores. In this article are our first benchmark results to share of a Samsung Exynos 5 Octa with a 1.6GHz Cortex-A15 configuration paired with a quad-core Cortex-A7 processor.
Every once in a while Phoronix readers that see photos of my office setup inquire about the glass computer desks I use. These particular desks are very functional, built well out of glass and metal, and are surprisingly affordable.
The 1.0 release of UPower, the abstraction layer for enumerating power devices and other power-related tasks that were formerly handled by HAL and then formerly known as DeviceKit-Power, is approaching.
The latest open-source work being done for improving Linux thermal monitoring and tuning is the TMON project that hopes to be mainlined within the Linux kernel.
Imagination Technologies, a name notorious amongst Linux users largely over the company's shoddy Linux driver support for their PowerVR graphics cores, unveiled a new processor core today. Announced today in London was Imagination's first MIPS "Warrior P-Class" CPU core.
ARM and other Linux stakeholders are still working to bring power-aware scheduling to the kernel.
A set of eight patches were published today for the Linux kernel that implement an extended hardware error log driver that provides enhanced Intel MCA event logging. With this driver, certain errors are more useful for users like being able to report the particular memory RAM DIMM where a memory corrected error happened and other detailed information not currently exposed via the Linux kernel.
As first reported yesterday on Phoronix, there's a new effort to raise one million dollars for a LGPLv3-licensed FPGA-based shader-supported graphics processor. Today the Kickstarter campaign kicked off with details in full on this new project.
A company is going to attempt to open-source their graphics accelerator 2D hardware design under the LGPLv3 license. Additionally, they claim for one million dollars they would be able to come up with a 3D shader-based open-source graphics accelerator.
UPower 0.9.22 was released today as mostly a bug-fix release but there's also a couple of new items.
The Lima graphics driver for open-source ARM Mali GPU support on Linux has some performance advantages of ARM Holdings' binary blob, but there's no upstream interest in having the driver mainlined in Mesa.
Rob Clark of the fast-growing Freedreno project provided a status update earlier this week at the X.Org Developers' Conference concerning his open-source ARM Qualcomm graphics driver, the Lima driver for ARM' Mali, GRATE for NVIDIA's Tegra, and Etnaviv for Vivante graphics hardware.
As a forewarning if you use LM-Sensors' sensor-detect program for detecting available hardware sensor/monitoring drivers of your system hardware, the open-source program is causing "serious trouble" for some newer hardware.
Yesterday's exciting news from LinuxCon NA 2013 was Gabe Newell's keynote where he talked about Linux as the future of gaming and exciting news coming next week. Today the interesting topic at LinuxCon is about IBM investing another billion dollars towards Linux and promoting its POWER architecture.
Apple released the iPhone 5S today and it's powered by their own A7 chip, which is a 64-bit ARM SoC and claims to be up to twice the CPU and graphics performance of its predecessor. The Apple A7 SoC has over one billion transistors and its interesting to see it being a 64-bit processor while ARM doesn't yet have out its own 64-bit chips in the wild yet. While the A7 is interesting, Apple isn't yet ready to comment on the compiler support.
