AMD Graphics: Big Navi, RADV and Radeon

  • 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.
