AMD Graphics: Big Navi, RADV and Radeon

Filed under
Graphics/Benchmarks
  • Fishy AMD Sienna CiChlid reference gets added to Linux driver patches, likely to be 'Big Navi' Navi 21

    About 207 patches for a new AMD GPU codenamed Sienna CiChlid have been committed to the AMD Radeon Linux Driver. Evidence from these patches suggests that Sienna CiChlid could, in fact, be Navi 21 aka Big Navi. The Sienna CiChlid Linux driver patches confirm support for VCN 3.0 and DCN 3.0 while a leaked slide indicates GDDR6 support and advanced clock and voltage control.

  • RADV Enables Zero vRAM Option For All Games With VKD3D

    Mesa's Radeon "RADV" Vulkan driver is now enabling the "zero vRAM" option for all VKD3D games -- Direct3D 12 titles running on Steam Play / Wine with this D3D12 to Vulkan layer -- in order to workaround various rendering bugs.

    Doom Eternal (native Vulkan, but still requires this workaround), Metro Exodus, and various other DirectX 12 games that rely on VKD3D when running under Steam Play / Wine have been hitting "colorful graphical aberrations" with the RADV driver but the issues go away when setting RADV_DEBUG=zerovram. As such, that option is now being enabled by default when VKD3D is present.

  • Radeon ROCm 3.5 Released With New Features But Still No Navi Support

    Radeon Open Compute 3.5 (ROCm 3.5) is now available with a number of improvements but surprisingly still no GFX10/Navi support.

    ROCm 3.5 was released today as the successor to ROCm 3.3 with no v3.4 milestone having been made public. Highlights of ROCm 3.5 include:

    - The Heterogeneous Compute Compiler (HCC) has been deprecated in favor of the HIP-Clang compiler for compiling HIP programs. The HIP-Clang code has been seeing a lot of work upstreamed into LLVM/Clang os overall this should be good in the long-run.

AMD Big Navi graphics card may have been spotted...

Mozilla: Rustup 1.22.0, Servo and Performance Improvements via Formally-Verified Cryptography in Firefox

    • Announcing Rustup 1.22.0

      The rustup working group is happy to announce the release of rustup version 1.22.0. Rustup is the recommended tool to install Rust, a programming language that is empowering everyone to build reliable and efficient software.

    • This Week In Servo 131

      Welcome back everyone - it’s been a year without written updates, but we’re getting this train back on track! Servo hasn’t been dormant in that time; the biggest news was the public release of Firefox Reality (built on Servo technology) in the Microsoft store. In the past week, we merged 44 PRs in the Servo organization’s repositories.

    • Performance Improvements via Formally-Verified Cryptography in Firefox

      Cryptographic primitives, while extremely complex and difficult to implement, audit, and validate, are critical for security on the web. To ensure that NSS (Network Security Services, the cryptography library behind Firefox) abides by Mozilla’s principle of user security being fundamental, we’ve been working with Project Everest and the HACL* team to bring formally-verified cryptography into Firefox. In Firefox 57, we introduced formally-verified Curve25519, which is a mechanism used for key establishment in TLS and other protocols. In Firefox 60, we added ChaCha20 and Poly1305, providing high-assurance authenticated encryption. Firefox 69, 77, and 79 improve and expand these implementations, providing increased performance while retaining the assurance granted by formal verification.

Stable Clonezilla live 2.6.7-28 Released

This release of Clonezilla live (2.6.7-28) includes major enhancements and bug fixes.
ENHANCEMENTS and CHANGES from 2.6.6-15

  • The underlying GNU/Linux operating system was upgraded. This release is based on the Debian Sid repository (as of 2020/Jun/30).
  • Linux kernel was updated to 5.7.6-1.
  • ocs-iso, ocs-live-dev: sync syslinux-related files when copying syslinux exec files.
  • When creating recovery iso/zip file, if it's in Clonezilla live environment, we have those syslinux files. Use that first so the version mismatch can be avoided. Ref: https://sourceforge.net/p/clonezilla/support-requests/127/
  • Move grub-header.cfg from bootx64.efi to grub.cfg so that it's more flexible.
  • To avoid conflict with the patch of grub in CentOS/Fedora, for GRUB EFI NB MAC/IP config style, the netboot file is now like grub.cfg-drbl-00:50:56:01:01:01 and grub.cfg-drbl-192.168.177.2 not grub.cfg-01-* anymore.
  • Add xen-tools
  • Partclone was updated to 0.3.14. The codes about xfs was updated to be 4.20.0.
  • Package exfat-fuse was removed since the kernel has module for that.
  • A better mechanism to deal with linuxefi/initrdefi or linux/initrd in the grub config was added.

Pico-ITX board based on i.MX8M ships with Linux BSP

F&S has launched a $407 and up “armStone MX8M” Pico-ITX SBC that runs Linux on an i.MX8M with up to 8GB LPDDR4 and 64GB eMMC with GbE, WiFi/BT, 5x USB, MIPI-CSI, DVI, and a mini-PCIe slot. F&S Elektronik Systeme originally announced the NXP i.MX8M-based armStone MX8M Pico-ITX board in early 2018 with an intention to begin sampling in Q2 of that year. The i.MX8M-based SBC has finally arrived, selling for 360 Euros ($407) in a kit that includes cables, a Yocto/Buildroot BSP, and full access to documentation. The key new addition since the 2018 announcement is a mini-PCIe slot and SIM card slot. Instead of supplying 4x USB 2.0 host ports, you get 2x USB 3.0 and 2x USB 2.0, and the micro-USB OTG port has been updated from 2.0 to 3.0. Read more
