From c986d860398ff44c32a612b3d8dfc9f89ffe5e52 Mon Sep 17 00:00:00 2001 From: Peter Maydell Date: Tue, 22 Aug 2023 17:31:05 +0100 Subject: [PATCH] target/arm/ptw: Don't set fi->s1ptw for UnsuppAtomicUpdate fault For an Unsupported Atomic Update fault where the stage 1 translation table descriptor update can't be done because it's to an unsupported memory type, this is a stage 1 abort (per the Arm ARM R_VSXXT). This means we should not set fi->s1ptw, because this will cause the code in the get_phys_addr_lpae() error-exit path to mark it as stage 2.
