From 5bf1a71c5b7b2d1999f65c08b4d82b5dec9f3013 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Volker=20R=C3=BCmelin?= Date: Sun, 17 Sep 2023 08:58:13 +0200 Subject: hw/audio/es1370: trace lost interrupts MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit It turns out that there are drivers which assume that interrupts can't be lost. E.g. the AROS sb128 driver is such a driver. Add a lost interrupt tracepoint to debug this kind of issues.
