AMD will reportedly release the last feature update planned for the AMDGPU and AMDKFD drivers to DRM-Next for Linux 5.20, in preparation for the release of RDNA 3. The merger window will open later this month, with companies like AMD and recently reported Intel adding features to kernel support being finalized in preparation for the next generation of graphics hardware from both tech giants.
AMD is preparing its next-generation RDNA 3 architecture and AMD’s CDNA-based gas pedal, also known as AMD Instinct, to enable its new hardware on a “block-by-block basis” when the company begins rolling out its latest computer components later this year. The current state of development is not as obvious as previous Linux driver patches.
AMD has not reported whether they have completed the update to Linux 5.20 kernel support, but they are expected to be very close to completion as the AMD Radeon RX 7000 GPU is set to debut in the coming months. However, it is assumed that AMD’s integration of their RDNA 3 update with Linux 5.20 is not yet confirmed after the product launch. In this case, open source users will have to rely on third-party solutions until the company is able to fully finalize the integration in the process.
Today, the final DRM-Next feature pull shows more AMD GPU Linux driver integration just as AMD can add previous code and fixes to the Linux 5.20 kernel. The updates added to the kernel by AMD include.
“Display Core Next (DCN) v3.2 block
Support DCN 3.1.4
SMU13 update
Soft reset handling for GFX11 (RDNA 3) graphics and SDMA 6 blocks
Soft reset processing support for GFX11 is “critical to ensure any stalls or issues with the current patch.” SubVP” is a new display core (DC) component that allows subviewport functionality. This component is a new DCN 3.2 hardware feature, but it is not yet known what the full capabilities of the SubVP feature will be.
AMD’s latest pull also adds “DC SubVP support”. AMD’s pull update for Linux also integrates DisplayPort Multistream Transport (DP MST), many audio patches, and modifies the GART size on recent APUs to add Scatter and Gather display support. Finally, AMD has also integrated queries for the GFXOFF status of the VanGogh series APUs, enhanced buffer object field fixing, and some AMDKFD modifications.
