From ee0a63d0dac825e9a5133b073ec3a843d8b7e206 Mon Sep 17 00:00:00 2001 From: Julian Ganz Date: Mon, 27 Oct 2025 11:03:23 +0000 Subject: [PATCH] target/loongarch: call plugin trap callbacks MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit We recently introduced API for registering callbacks for trap related events as well as the corresponding hook functions. Due to differences between architectures, the latter need to be called from target specific code. This change places hooks for loongarch targets. This architecture has one special "exception" for interrupts and no host calls.
