Another Linux FBDEV Drover Poised For Removal In Favor Of Superior DRM Alternative

For years there have been calls to deprecate Linux's FBDEV and work around replacing FBDEV drivers with modern Direct Rendering Manager (DRM) drivers. While hardware vendors are now trending in the direction of DRM drivers (and the FBDEV emulation support if needed) after the embedded space was somewhat of a holdout, FBDEV drivers and the subsystem still exist as we roll into 2021. But at least one more FBDEV driver is now looking likely for removal in favor of its modern and maintained DRM counterpart.

RADV Vulkan Driver Enables NGG For AMD VanGogh APUs

Up to now the Mesa Radeon Vulkan driver "RADV" has only enabled Next-Gen Geometry (NGG) support by default for discrete graphics cards. But now that requirement is lifted for supporting NGG on forthcoming GFX10.3 (RDNA 2) APUs.

Linux 5.10-rc6 Released - This LTS Kernel Now Appearing In Good Shape

While in recent weeks Linus Torvalds was becoming increasingly concerned over the size of the changes in Linux 5.10, 5.10-rc6 is out this evening and fortunately it has calmed down. At this point Linus is appearing relieved that Linux 5.10 will be in good shape for shipping on time and without any major concerns.

Firefox 83 vs. Chrome 87 On Intel Tiger Lake + AMD Renoir Under Linux

With this month's release of Chrome 87 having more performance improvements while Firefox 83 debuted with its "Warp" JavaScript improvements, it's a good time for some fresh Linux web browser benchmarks of these two main options. Plus with Firefox 84 to begin enabling WebRender by default in some Linux configurations, there is also a fresh run of Firefox with WebRender enabled.

Xilinx Continues Their Open-Source FPGA Upstreaming Push For The Linux Kernel

Earlier this month we covered the news of Xilinx is looking to upstream their open-source "AI Engine" driver to the Linux kernel. This comes as Xilinx and AMD are working on Radeon Open eCosystem (ROCm) support for their FPGAs with AMD being in the process of acquiring the FPGA giant. Now more open-source code is looking to be included in the Linux kernel tree.

SVT-AV1, Dav1d Speeding Along AV1 Into 2021

While consumer GPUs are reaching market with AV1 decode acceleration, there still is the matter of the various media APIs and multimedia software making use of it. In cases where that is missing or the user doesn't yet have a supported Tiger Lake / Ampere / RDNA2 GPU, the dav1d decoder remains the fastest open-source CPU-based AV1 decoder. Similarly, SVT-AV1 remains the fastest CPU-based AV1 encoder available.

Zink OpenGL-On-Vulkan Development Now Being Done On RADV With Navi GPU

Mike Blumenkrantz who has spent most of the year working on the "Zink" Gallium3D code for allowing universal OpenGL over Vulkan translation and took this Mesa code to OpenGL 4.6 compatibility and in some cases 90%+ the performance of a native OpenGL driver is now working on Zink development from a Radeon Navi graphics card with the RADV driver, which may in turn help uncover bugs and areas of optimizations for the open-source Radeon driver stack.

The Peculiar State Of CPU Security Mitigation Performance On Intel Tiger Lake

One area not talked about much for Intel's latest Tiger Lake processors are hardened CPU security mitigations against the various speculative execution vulnerabilities to date. What's peculiar about Tiger Lake though is now if disabling the configurable mitigations it can actually result in worse performance than the default mitigated state. At least that's what we are seeing so far with the Core i7 1165G7 on Ubuntu 20.10 Linux is the opposite of what we have been seeing on prior generations of hardware.

Following FUSE & CUSE, Now There Is "MUSE" For MTD In Userspace

FUSE is well known to longtime Linux users for allowing file-systems to be implemented in user-space for where a Linux kernel port isn't feasible for portability or licensing restrictions, among other factors. There is also CUSE for character devices in user-space. Now being based on FUSE, there is "MUSE" being worked on for MTD in user-space.
