AMD Squeezes In More RDNA4 Changes For Linux 6.14 - Enables Cleaner Shader On GFX12
While the main feature pull of new and updated kernel graphics/accelerator drivers were merged already for the ongoing Linux 6.14 merge window, an additional set of AMDGPU changes were sent out this week for squeezing into this next kernel release.
Friday's pull request of additional AMDGPU and AMDKFD material is mostly about bug fixes for existing and newly-introduced issues in Linux 6.14. By clearing these resources between workloads, it helps prevent possible data leakage and ensures better security/reliability with the upcoming RDNA4 graphics cards. I haven't seen any public communication from AMD driver developers about their motivation for adding this cleaner shader functionality at this stage as opposed to something that could have been done years ago, if it's due to new customer demands / security concerns or other factors.
