Makes sense, having hotplug events would be nice. I've got a standalone bios emulator (based on the X int10 library) that I hope to open source soon, we could use that as a starting piont for the reset app. +static void vga_enable(struct pci_dev *pdev, unsigned int enable) ... + outb(~0x01 & inb(0x3C3), 0x3C3); + outb(~0x08 & inb(0x46e8), 0x46e8); + outb(~0x01 & inb(0x102), 0x102); + pdev->resource[PCI_ROM_RESOURCE].flags &= ~IORESOURCE_VGA_ACTIVE; + if (pdev == vga_active) + vga_active = NULL; + bridge_no(pdev); Those ins and outs won't work on all platforms unless they have a base address (assigned by arch code) associated with them. But then again, I suppose if a platform supports more than one legacy I/O space, it also supports multiple active VGAs, so maybe this enable/disable code isn't needed for them...
