From d8a3220005d74512677b181e3a32cd94b13ddf49 Mon Sep 17 00:00:00 2001 From: Helge Deller Date: Mon, 1 Jan 2024 21:47:30 +0100 Subject: [PATCH] hw/hppa/machine: Disable default devices with --nodefaults option Recognize the qemu --nodefaults option, which will disable the following default devices on hppa: - lsi53c895a SCSI controller, - artist graphics card, - LASI 82596 NIC, - tulip PCI NIC, - second serial PCI card, - USB OHCI controller. Adding this option is very useful to allow manual testing and debugging of the other possible devices on the command line.
