Radeon RADV Vulkan Driver Adopts An LLM Policy

The Mesa RADV driver that provides Vulkan API support for AMD Radeon GPUs on Linux has adopted its own policy around AI / large language models (LLMs) for code contributions. Beyond Mesa having its own AI/LLM policy, the Radeon RADV driver has instituted its own loose policy around AI/LLMs. Samuel Pitoiset of Valve's Linux graphics team and one of the prolific contributors to the RADV driver is the one that took the initiative and moved forward in adding this RADV-specific policy. Ultimately it's a loose one in not outright forbidding AI/LLM-based contributions but discourages its use and leaves the door open to closing merge requests that were AI generated. The new policy is: "If you find a bug or shortcoming in RADV and cannot address it yourself, file an issue on the tracker. LLM-assisted MRs require a good understanding of the codebase, and reviewing them has a real cost. Reviewers/maintainers may close such MRs at their discretion. LLM-written issues are discouraged: they tend to be verbose and hard to read. Please describe the issue in your own words. LLM-generated reproducers are fine as long as you have reviewed them and they demonstrate the bug." Pitoiset rationalized the need for this RADV policy due to beginning to see more AI-generated patches and wanting to get out ahead of them before the developers become overwhelmed. He wrote in the merge request for this policy: "We are starting to get slightly more LLM MRs by external contributors these days for RADV and it seems better to state this now before getting flooded." The policy was merged today to Mesa Git.
