From 8f2a1c5926bf933abce54de23d5ae44371c50e23 Mon Sep 17 00:00:00 2001 From: Helge Deller Date: Tue, 28 Jan 2025 19:47:31 +0100 Subject: [PATCH] target/hppa: Add CPU diagnose registers Add the diagnose registers (%dr) to the CPUArchState. Those are mostly undocumented and control cache behaviour, memory behaviour, reset button management and many other related internal CPU things.
