Following the recent emergency release of Ubuntu 16.04.6 LTS to get out updated install media that addresses the recent APT security vulnerability and in the process other bug fixes too, Ubuntu 14.04.6 has now been released as a similar update...

A seldom advertised experimental feature of the AMDGPU kernel driver has long been the GCN 1.0/1.1 graphics support. By default these Southern Islands and Sea Islands graphics processors default to the Radeon DRM driver, but with some kernel command lime parameters can use the AMDGPU Direct Rendering Manager driver. The AMDGPU code path is better maintained since it's used for all modern Radeon GPUs, using AMDGPU opens up Vulkan driver support, and possible performance benefits. It's a while since last testing the Radeon vs. AMDGPU driver performance for these original GCN graphics cards, so here are some fresh benchmarks using the Linux 5.0 kernel and Mesa 19.1-devel.

The UBports community that continues maintaining Ubuntu Touch has today released their OTA-8 update...

While there were many Linux gaming benchmarks within our recent GeForce GTX 1660 Ti Linux review, there were requests for 1080p tests and some other benchmarks... For honoring those requests, with some of them being made by our premium supporters, here are 117 graphics benchmarks tested not only on the GTX 1660 Ti but also the RTX 2060 and on the AMD side was the Radeon RX 590 and RX Vega 56 for an interesting mid-range graphics card comparison.

With the in-development Linux 5.1 is a big step forward to the kernel's live-patching infrastructure for this functionality that allows primarily applying security updates against the running kernel without the need for reboots...

Recently I published a number of Linux 5.0 I/O scheduler benchmarks on laptop and desktop hardware with solid-state storage. A number of Phoronix readers were interested in seeing similar tests done but with traditional hard drives, so here are those results using two different drives and the different blk-mq I/O scheduler options with the new Linux 5.0 kernel.

AMD developers today posted a set of twenty patches implementing RAS support for the AMDGPU Linux kernel diver...

One week ahead of the official debut of GNOME 3.32, the release candidate will be out this week and GNOME Shell along with the Mutter compositor have outed their 3.31.92 release...

With the initial Iris Gallium3D driver that was merged into Mesa at the end of February from our tests on UHD Graphics the performance is quite promising considering the early stage of this new open-source OpenGL driver and it not yet being fully tuned/optimized. The Iris Gallium3D driver support goes back to Broadwell CPUs so I decided to run some benchmarks with the legendary Core i7 5775C that features the Iris Pro Graphics 6200 with 128MB of eDRAM.

For years Debian developers have been planning for a merged /usr concept where the /{bin,sbin,lib}/ directories becoming symbolic links to /usr/{bin,sbin,lib}/. With the upcoming Debian 10 Buster is the initial step of their plan after it was postponed from Debian Stretch...

SPOILER is the newest speculative attack affecting Intel's micro-architecture...

While Intel may be developing the Iris Gallium3D driver as their future OpenGL driver, they haven't given up all work on their existing "i965" classic Mesa driver. Hitting Mesa 19.1's development code this morning is support for threaded OpenGL with this existing and widely-used driver on Linux systems...

The x86/pti updates for Linux 5.1 is bringing a new PR_SPEC_DISABLE_NOEXEC option where speculation protection for SSBD doesn't end up being passed to new processes started by exec in such use-cases where it's safe to do so. Utilizing this option will thus eliminate the overhead associated with this Spectre Variant 4 "Speculative Store Bypass" behavior...

While the upstream Linux kernel developers may not be interested in adding all of the CPU compiler tuning optimizations carried by Gentoo for their kernel builds, if you are after just "-march=native" compiler tuning to optimize your kernel build for the CPU being used, an updated patch is now available...

Now that the Linux Vendor Firmware Service (LVFS) and Fwupd updating mechanism for firmware/BIOS updates is supported by all major vendors and has already served up more than five million firmware files, their newest focus is on easing the roll-out of firmware updates in enterprise settings...

As usual, following yesterday's release of Linux 5.0 the GNU/FSF folks have put out their re-base of their version of the Linux kernel that strips out support for drivers depending upon binary-only firmware, the ability to load non-free (closed-source) kernel modules, and other functionality removed that isn't in strict compliance with open-source standards...

Collabora's Tomeu Vizoso has posted an initial set of patches he's been working on along with Rob Herring on developing a new open-source kernel DRM driver for Arm's Bifrost and Midgard graphics hardware...

It's always been a bit odd how the de facto Vulkan SDK is through LunarG rather than The Khronos Group, which could lead to confusion for those not familiar with the great folks at LunarG. But now it will be more clear with LunarG officially donating their Vulkan software development kit to Khronos...

Dirt Rally 2.0 was released last week by Codemasters as the successor to 2015's Dirt Rally and another title on the EGO Engine. While Dirt Rally saw a native Linux port, Dirt Rally 2.0 hasn't seen any port announced by Feral Interactive (though they are currently porting DiRT 4 to Linux), but what's very exciting is this brand new Windows game runs great under Valve's Steam Play with Proton and DXVK! The experience for Dirt Rally 2.0 is quite great on Linux already thanks to Steam Play and with this being a benchmark-friendly game, here are some NVIDIA GeForce and AMD Radeon benchmarks of this racing game on Linux.

With there being a lot of interest from when Intel recently open-sourced their SVT-AV1 video encoder and more recently their VP9 video encoder also under the "Scalable Video Technologies" umbrella, here are benchmarks from 27 different systems showing off their performance. Plus for kicks there are also some other CPU-based video encode benchmarks including AOM-AV1 and others...
