From: Bernhard Beschow Date: Fri, 30 Jun 2023 07:37:11 +0000 (+0200) Subject: hw/pci-host/i440fx: Add "i440fx" child property in board code X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=f00f5e4b00e2cb414927b560cd6a82fad4dfc6e2;p=qemu.git hw/pci-host/i440fx: Add "i440fx" child property in board code The parent-child relation is usually established near a child's qdev_new(). For i440fx this allows for reusing the machine parameter, thus avoiding qdev_get_machine() which relies on a global variable.
