From 0438aadfa69a345136f5ba4f582e0f769450ee0d Mon Sep 17 00:00:00 2001 From: David Gow Date: Sat, 17 Dec 2022 12:44:36 +0800 Subject: [PATCH] rust: arch/um: Add support for CONFIG_RUST under x86_64 UML MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit CONFIG_RUST currently supports x86_64, but does not support it under UML. With the previous patches applied, adding support is trivial: add CONFIG_HAVE_RUST to UML if X86_64 is set. The scripts/generate_rust_target.rs file already checks for CONFIG_X86_64, not CONFIG_X86, so is prepared for UML support. The Rust support does not currently support X86_32. Also, update the Rust architecture support documentation to not that this is being maintained: I intend to look after this as best I can.
