  • Open-Source C.A.S. Vulkan Layer - Similar to Radeon Image Sharpening But For Any GPU

    AMD's Radeon Image Sharpening feature is designed to improve image quality with minimal performance costs. However, it is only supported by Radeon Polaris / Vega / Navi graphics cards and only under Microsoft Windows 10. An independent open-source project has implemented contrast adaptive sharpening support for Vulkan that is similar to Radeon Image Sharpening but will work for any Vulkan-enabled GPU -- including NVIDIA GPUs.

  • MSM+Freedreno Driver Stack Adding Support For The Adreno 510 GPU

    While the MSM+Freedreno open-source graphics driver stack already supports the Adreno 500 and 600 series, one of the GPUs not seeing support until now was the basic Adreno 510. Kernel patches are pending for A510 enablement while the Mesa support was already merged.

    The Adreno 510 is the graphics processor within the Snapdragon 650, 652, and 653 models and used in lower-end devices. With the kernel and Mesa patches, the Adreno 510 is now working on the likes of the Sony Xperia X and X Compact smartphones.

  • AMD Lands Greater Direct State Access Support Within Mesa

    Landing this week in Mesa 19.3-devel were more functions being implemented around the big OpenGL EXT_direct_state_access extension.

    OpenGL's direct state access functions are intended to allow more OpenGL state to be accessed/updated directly aside form the selector commands. Using EXT_direct_state_access allows for various efficiency improvements.

Debian Releases Updated Intel Microcode for Coffe Lake CPUs, Fixes Regression

Last month on November 13th, the Debian Project shipped updated CPU microcode for various types of Intel CPUs to mitigate the TAA (TSX Asynchronous Abort) vulnerability (CVE-2019-11135). But not all Intel CPU models were covered by the update, so they released a new intel-microcode security update that addresses this flaw for Coffe Lake processors too. "This update ships updated CPU microcode for CFL-S (Coffe Lake Desktop) models of Intel CPUs which were not yet included in the Intel microcode update released as DSA 4565-1," reads the security advisory. "We recommend that you upgrade your intel-microcode packages." Read more

Some fixes in Accessibility Inspector in Firefox 72

Firefox 72, currently in beta, received some fixes to the Accessibility Inspector this week. Here they are. The first fix is to a longer standing issue. If you opened Accessibility Inspector by right-clicking an element and choosing Inspect Accessibility Properties, keyboard focus would not land on the Inspector or Properties tree view, but in limbo somewhere on the document. You had to tab a couple of times to get focus to the correct place. Well, that will be no more. From now on, keyboard focus will land in the properties tree, so you can directly start exploring the name, role, states etc., of the element you are interested in. Related to that, if you selected to inspect an accessibility element’s property either from the browser or DOM Inspector context menus, the selected row in the Accessible Objects tree would not always scroll to actually show the selected item. That too has been fixed. Read more

Sabrent Rocket 4.0 NVMe Gen4 Linux Benchmarks Against Other SATA/NVMe SSDs

When it comes to PCIe 4.0 NVMe SSDs, the drives we have been using are the Corsair Force MP600 that have been working out great for pairing with the newest AMD Ryzen systems. But a Black Friday deal had the Sabrent 1TB Rocket NVMe 4.0 Gen4 PCIe M.2 SSD on sale, so I decided to pick one up to see how it was performing on Ubuntu Linux. Here are benchmarks of the Sabrent Gen4 NVMe SSD, which in the 1TB capacity can be found for $150~170 USD. The Sabrent 1TB Rocket NVMe 4.0 Gen4 (SB-ROCKET-NVMe4-1TB) features Toshiba BiCS4 96L BGA132 TLC NAND flash memory, Phison PS5016-E16 flash controller, and Sabrent rates its performance for sequential reads up to 5000MB/s and sequential writes up to 4400MB/s. Obviously for hitting those peak performance figures this solid-state drive needs to be installed in a PCI Express 4.0 M.2 slot. Read more
