Linux 5.10 ARM64 Has A "8~20x" Performance Optimization Forgotten About For Two Years

1 hour 56 min ago
Last week was the main set of ARM 64-bit architecture updates for Linux 5.10 while today a second batch of changes were sent in for this kernel. That first round had the Memory Tagging Extension (MTE) and Pointer Authentication support among other improvements while this secondary pull has two notable performance optimizations...

Linux Developers Discussing Possible Kernel Driver For Intel CPU Undervolting

Wednesday 21st of October 2020 06:00:00 PM
While the Intel Extreme Tuning Utility (XTU) on Windows allows for undervolting laptop processors, currently on Linux there isn't any Intel-endorsed way for undervolting your CPU should you be interested in better thermal/power efficiency and other factors. But a hypothetical Linux kernel driver could be coming for filling such void...

Windows 10 vs. Ubuntu 20.10 Performance With Intel Tiger Lake, AMD Renoir

Wednesday 21st of October 2020 02:30:00 PM
Stemming from our initial Intel Core i7 1165G7 "Tiger Lake" benchmarks on the Dell XPS 13 9310 last week and then also discovering better single-threaded performance on Ubuntu 20.10, one of the pressing questions was whether this is expected performance on Linux or if it's coming up short of Microsoft Windows for this first tier-one notebook to market with Intel Tiger Lake. So following those earlier tests I proceeded to do a Windows 10 Pro with all available updates comparison on Ubuntu 20.10 with the i7-1165G7. For added context, the same software stack and tests were repeated on an AMD Ryzen "Renoir" notebook.

Facebook Is Looking To Upstream Their BOLT Binary Performance Optimizer Into LLVM

Wednesday 21st of October 2020 11:00:00 AM
Facebook's BOLT is a multi-year project focused on speeding up the performance of binaries. This open-source project initially focused on being able to better optimize Linux x86_64/ARM64 ELF binaries as a post-link optimizer. BOLT has been seeing much success with even Google using it now for better performance and now there is work to upstream it as part of the LLVM project...

Intel OpenGL/Vulkan Linux Drivers Strike Another Optimization For Tiger Lake

Wednesday 21st of October 2020 05:45:35 AM
It was just on Monday that Intel's talented open-source developers merged a hefty Tiger Lake graphics optimization into the Mesa 20.3 code that for some games/software can be around ~11% faster thanks to greater caching. Just a day later another optimization has arrived for helping these latest-generation Intel graphics...

NVIDIA Ships Vulkan Driver Beta With Fragment Shading Rate Control

Wednesday 21st of October 2020 04:07:27 AM
This week's Vulkan 1.2.158 spec release brought the fragment shading rate extension to control the rate at which fragments are shaded on a per-draw, per-primitive, or per-region basis. This can be useful similar to OpenGL and Direct3D support for helping to allow different, less important areas of the screen be shaded less than areas requiring greater detail/focus...

PineCube camera kit arrives for $30

Pine64’s $30 PineCube camera dev kit runs Linux on an Allwinner S3 and offers a 5MP, OmniVision OV5640 based M12 camera with IR night-vision plus audio I/O, WiFi, 10/100 LAN with PoE, USB, 26-pin GPIO, and optional battery and display. The open-spec PineCube was first revealed by Pine64 in early 2019 as a device called The CUBE with an 8-megapixel Sony iMX179 CMOS sensor. By early this year, it was recast as the CUBE IP Camera, which was promised for a delayed 2Q release due to issues with the Sony camera implementation. Since then, Pine64 switched to a 5MP OmniVision OV5640 sensor and a new PineCube name. The camera dev kit has now shipped for $30. Read more
