From 8a315a788a4bb4c09390dbadf934289b2cfcecb5 Mon Sep 17 00:00:00 2001 From: Julian Ganz Date: Mon, 27 Oct 2025 11:03:33 +0000 Subject: [PATCH] target/sparc: 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 SPARC (32bit and 64bit) targets. We treat any interrupt other than EXTINT and IVEC as exceptions as they appear to be synchroneous events.
