• The Mesa RADV Vulkan Driver Will Soon Have An Option That Boosts Performance 30%+ On RDNA2 GPUs By Rendering Less
  
  
  Those who have the very latest Radeon RX 6000 series graphics cards from AMD will get the option of doing fewer fragment shader invocations per pixel rendered in Vulkan games when Mesa 21.1 is released come May. This can provide a huge performance-boost, or nearly none at all, depending on the game or workload. The new Mesa option requires variable rate shading support in hardware, so it is only for those who have a shiny new GPU from AMD.
  
• AMD ROCm 4.1 Is Released With A Fine New Notice Saying "GUI-Based software" Is "Not Supported"
  
  
  The latest AMD Radeon Open Compute (ROCm) stack brings a few new features for AMDs data-center customers. OpenCL, which is what most GNU/Linux desktop applications use for GPU compute, is not even mentioned in the "What's New" section of the release notes. There is, instead, a shiny new notice on the ROCm documentation website saying "GUI-based software applications are currently not supported".

  AMD announced their Q3 2020 quarterly results early due to an all-stock acquisition of the American semiconductor company Xilinx for $35 billion. AMD pulled in $2.8 billion in revenue in Q3 2020, up 58% compared to Q3 2019. Their quarterly earnings were even more impressive. Q3 2020 was AMD's best quarter in history in terms of both revenue and earnings.
  
• Sensor Fusion Hub Driver For AMD Laptops With Gyroscopes Is Coming To Linux 5.11
  
  
  It's been a long and hard road to acceptance for AMD's Sensor Fusion Hub Linux driver. The first revision was submitted to the Linux kernel Mailing List in January 2020. It took eight revisions and a lot of effort before Jiří Kosina finally accepted it into the hid.git#for-5.11 tree, almost guaranteeing that it will become a part of Linux 5.11.
  
• AMDVLK 2020.Q4.1 Is Released With A New Vulkan Extension And Three Game-Specific Fixes
  
  
  AMD has released a new version of their AMDVLK Vulkan driver for Linux with support for one new Vulkan extensions and game-specific fixes for Wolfenstein II: The New Colossus, Second Extinction and X-plane. Performance is still overall worse than the AMD RADV Vulkan driver that comes with Mesa 20.2.0 and performance is much worse in specific graphics benchmarks and image up-scaling.
  
• Linux 5.9 Is Released With New Drivers, Improved AMD GPU Support, And Support The x86-64 FSGSBASE CPU Instructions
  
  
  It was a bumpy release-cycle for Linux 5.9 with one release candidate refusing to show anything graphical on Intel GPUs. The final 5.9 release doesn't have that problem. It has have quite a lot of new features such as support for upcoming AMD graphics cards, support for the FSGSBASE x86-64 instructions, a Corsair RGB hub and a lot more.
  
• AMD Hopes To Get Sensor Fusion Hub Driver For AMD Laptop Gyroscopes And Other Sensors Into Linux 5.10
  
  
  AMD's Sandeep Singh has submitted yet another revision of AMD's Linux HID driver for the Sensor Fusion Hub hardware in all AMD laptops based on Ryzen processors. That makes it eight in total. This could be the lucky revision that makes it into the Linux kernel when the Linux 5.10 merge window opens up on Monday.
  
• AMD Announces Four 5000-Series Ryzen CPUs
  
  
  AMD announced four new 5000-series Zen3 processors in a marketing presentation titled "Where Gaming Begins" today. The processors have 6 to 16 cores and base clocks between 3.4 and 3.8 GHz with boost clocks up to 4.9 GHz. TDP is listed as 105W for all but the 6-core model. The new processors will have a MSRP between $300 and $800 when they reach stores on November 5th, 2020. AMD claims the processors will have a 19% IPC performance uplift.
  
• DXVK DirectX To Vulkan Translation Layer 1.7.2 Released
  
  
  The latest DXVK Direct3D 9 to 11 to Vulkan translation layer has seven game-specific fixes and some Direxct3D 9 fixes specific to AMD's AMDVLK Vulkan driver. DXVK can be used as an alternative to Wine's own wined3d DX 9-11 to OpenGL translation layer while we wait for Wine to get their own C-implemented DX 9-11 to Vulkan back-end ready.
  
• Linux 5.9-rc8 Is Out With PCIe IDs for AMDs Upcoming Sienna Cichlid GPUs
  
  
  We have examined the latest Linux 5.9 release candidate and found that it is actually possible to use it to boot and start X or Wayland on machines with Intel processors using Intel integrated graphics with this latest kernel release-candidate. That is an improvement since the total train-wreck disaster released as Linux 5.9-rc7.
  
• AMDVLK v-2020.Q3.6 Is Released With Four Game-Specific Fixes
  
  
  The latest AMDVLK driver has one new Vulkan extension and game-specific fixes for Doom VFR, Baldur's Gate 3 and Red Dead Redemption 2. AMDVLK's performance is still worse, in some cases far worse, than what the RADV Mesa Vulkan driver from Mesa 20.2.0 offers. AMDVLK v-2020.Q3.6 does offer better compatibility so it may be worth installing it side-by-side the Mesa RADV Vulkan driver if you own a AMD graphics card.
  
• AMD ROCm 3.8 Is Released
  
  
  The latest AMD Radeon Open Compute graphics stack offers absolutely dismal OpenCL performance in the LuksMark benchmark compared to the Mesa Clover OpenCL library from the newly released Mesa 20.2.0 graphics stack. It does have one thing going for it: It does support OpenCL 2.0, something Mesa Clover does not.
  
• Support For Mysterious AMD VanGogh and Dimgrey Cavefish GPUs Merged To The Mesa RadeonSI OpenGL Driver
  
  
  AMD merged support for two new graphics chips into the RadeonSI Mesa OpenGL driver for AMD graphics cards today: CHIP_DIMGREY_CAVEFISH and CHIP_VANGOGH. The patches were written back in July 2020. Dimgrey Cavefish is placed in the Navi (FAMILY_NV) family while VanGogh is something different. Both chips are in the GFX10 family with the features AMD markets as "RDNA2".
  
• AMD At The X.Org Developers Conference 2020: No-No Baking Your Graphics Card
  
  
  Linux kernel developer Rajneesh Bhardwaj from AMD's Radeon Open Compute team warned that you should absolutely not bake your graphics card at the X.Org developers conference this week. He explained the dangers and stressed "Don't try this at home!". He went on to detail the many runtime power management advancements the amdgpu kernel driver for AMD graphics cards has seen the last year.
  
• How the ACO Mesa Vulkan Shader Compiler For AMD GPUs Came To Be: From Prototype To Default
  
  
  The Vulkan ACO shader compiler for AMD graphics cards on Linux will be the default shader compiler when Mesa 20.2 is released later this month. Developer Timor Kristóf held a 40 minutes long and interesting talk about the development process and the efforts behind making ACO a reality at the The X.Org Developers Conference 2020. Here it is.
  
• AV1 Hardware Video Decode Support For AMD RX 6000 Series GPUs Coming In Linux 5.10
  
  
  AMD has historically been extremely slow compared to Nvidia and Intel when it comes to providing hardware video encoding and decoding capabilities for open video standards like VP8 and VP9. New patches by AMD Open Source Laboratory developer Alex Deucher show that AMD won't be dragging their feet for years before they add AV1 video decoding support to their hardware, it is already there in the upcoming RX 6000 series GPUs. VP9 and AV1 video encoding support is still severely lacking.
  
• AMD Reveals Picture Of RX 6000 Series GPU With 2 8-Pin PSU Connectors
  
  
  AMD has revealed a single picture of a RX 6000 series graphics card with three fans and two eight-pin power connectors. They shared no details beyond it being a "upcoming #RDNA2" card with a "brand new cooler design". What we can educationally guess from the latest Linux kernel code is that these cards will have sdma 5.2 and new a new display core called "Display Core Next 3.0".

Vulkan API compliance is updated to Vulkan 1.2.152. Performance is overall slightly worse than what the latest Mesa RADV Vulkan driver provides and magnitudes worse in very specific GPU stress tests.
  
• Linux 5.9 Brings Hardware Accelerated Video Playback To 10+ Year Old AMD Graphics Cards Using The "amdgpu" Linux Kernel Driver
  
  
  AMD kicked off their HD 7000 series graphics cards with the launch of the Radeon HD 7970 code-named "Tahiti" in December 2011. Linux users are finally able to get working Hardware Video Decoding and Vulkan support on these and other older AMD graphics cards using the Linux kernel's "amdgpu" driver.
