Following last week's big Phoronix Test Suite 10.0 and the new OpenBenchmarking.org, a small update is out this week to address some initial hiccups...
While all eyes are on the AMD Radeon RX 6000 "Big Navi" graphics cards set to be announced next week, it also looks like AMD is preparing for a Navi 1x "Blockchain" graphics card offering given the latest work in their open-source Linux driver...
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...
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'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...
The interesting work continues pouring in for Mesa 20.3 as the Q4'2020 feature release to this open-source graphics stack... The latest excitement is on the "Clover" front for Gallium3D OpenCL...
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...
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...
With Ubuntu 20.10 due for release this week I have begun testing near-final Ubuntu 20.10 builds on many more systems in the lab. Larger than our normal distribution/OS comparisons, here is the culmination of running hundreds of benchmarks (366 tests to be exact) under both Ubuntu 20.04 LTS with all available updates and then again on the Ubuntu 20.10 development state while testing on Intel Comet Lake.
Mesa 20.3 has merged a long work-in-progress patch series providing support for going from the modern NIR intermediate representation to TGSI as the conventional Gallium3D IR...
The ODF 1.3 Open Document Format specification was approved by the OASIS Committee at the start of the year and now as we approach the end of the year The Document Foundation is hoping to see ODF 1.3 support completed soon for this leading open-source office suite...
The System76 Thelio Major with AMD Ryzen Threadripper 3900 series is already a beast, but now this Linux PC vendor has managed to outdo themselves once again with the Thelio Mega...
Last week saw the XFS file-system with Linux 5.10 support timestamps until the year 2486 rather than year 2038 and other improvements too. This week a second round of XFS work has landed for Linux 5.10...
From my Tiger Lake testing so far with the Core i7 1165G7, the "Gen12" Xe Graphics have been quite compelling with a very nice upgrade over Gen11 and especially obvious win over the very common still Gen9 graphics. With Mesa 20.3, another measurable performance is on the way for the Intel Vulkan driver with Tiger Lake...
The fourth release candidate of OpenZFS 2.0 is now available for testing of this open-source ZFS file-system implementation currently for Linux and FreeBSD platforms...
Git 2.29 is now available with experimental support for using SHA-256 to increase security of code repositories over the possibility of intentional SHA-1 collisions with the current indices...
An independent party has slowly begun merging patches into mainline Mesa for allowing the open-source Radeon Vulkan driver "RADV" to build on Microsoft Windows...
Last week I published initial benchmarks of the Intel Core i7 1165G7 "Tiger Lake" performance on Linux with the Dell XPS 13 9310 Developer Edition laptop. Of most surprise from those preliminary Linux figures were finding that for some single-threaded workloads the performance was actually worse than the previous generation Ice Lake. Since then I've been running more tests around the clock with some interesting discoveries to note today. It is possible to enhance the single-threaded performance so it's performing better than Ice Lake as would be expected, but comes with lowering the multi-threaded performance compared to the results shared last week.
Independent Linux kernel developer Con Kolivas (and retired anaesthetist) is back on track with a new update to his "CK" patch-set and the MuQSS scheduler...
Should you want to use the Ada programming language for GPU programming, the GCC compiler has been working on CUDA support within its front-end for this safety and security minded language...
The "char/misc" area within the Linux kernel continues to have a bit of everything as the "catch all" pull request of the kernel not fitting into other existing subsystems...
Building off Linux 5.9 that featured initial support for Gen12 graphics on next year's Rocket Lake desktop platform along with other early enablement for Rocket Lake like RAPL support and other PCI ID additions, that work has continued for the Linux 5.10 cycle...
It was in October 1995 that Theo de Raadt began the OpenBSD project as a fork of NetBSD 1.0 following his resignation from the NetBSD core development team. Now twenty-five years later OpenBSD 6.8 has been released for marking the 25th anniversary of this popular BSD distribution...
The Linux 5.10 kernel "staging" changes have the usual assortment of changes throughout this area where premature kernel code goes prior to proving itself and meeting kernel coding quality standards...
Earlier this year Linux 5.6 brought initial USB4 support by leveraging Intel's existing Thunderbolt kernel support for which the updated USB specification is based. Succeeding kernels have continued maturing this USB4 implementation and that has continued with Linux 5.10...
One week past the Linux 5.9 official debut, Linux 5.9.1 is now available. Making this initial point release a bit more noteworthy is including the fixes for the "Bleeding Tooth" Bluetooth vulnerability made public this week...
Back in August was the surprise that Paragon Software is looking to mainline their NTFS read-write driver in the mainline Linux kernel after years of offering it as a commercial driver for those needing reliable support for this Microsoft file-system on Linux. Two months later they are now up to their ninth revision of this driver in their pursuit of mainline inclusion...
OpenBLAS 0.3.11 is out as the newest major feature release for this BLAS linear algebra library. While the version number may not make it seem like a big update, it is especially when it comes to new CPU support...
While NVIDIA is usually quite timely in supporting new versions of the Linux kernel and aim to have out a driver by the end of the release candidates for new series, in the case of the recently minted Linux 5.9 kernel it's taking a lot longer...
This week marked the release of Plasma 5.20 while KDE developers continue working towards not only Plasma 5.21 as the next desktop feature release but also providing fixes for next month's Plasma 5.20.1 release and the growing collection of KDE applications...
For weeks there have been patches getting the Zink OpenGL-on-Vulkan implementation to OpenGL 4.6 while mainline Mesa has been at OpenGL 3.0 support. Thankfully the out-of-tree patch delta is being reduced and this week in Mesa 20.3-devel the code has been upstreamed getting the support level to OpenGL 3.3...
The POWER architecture changes have been submitted for the Linux 5.10 kernel. As expected, the PowerPC 601 support is retired as that original 32-bit PowerPC processor from the early 90's...
