Hi Tycho,
Yes, writing 0 to the status resister should reset the device including all PCIE state. This implies that vi_reset_dev() needs to take the proper actions to bring the associated pci_devinst (which from the guest’s perspective isn’t a discrete element) back to it’s reset state too.
I'm not sure if the reset also hits PCIe state, if you're counting config space as part of that (e.g. BAR contents). As an example, the FreeBSD guest virtio code doesn't do any config space saves/restores around a reset.
later, Peter. _______________________________________________ freebsd-virtualization@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-virtualization To unsubscribe, send any mail to "freebsd-virtualization-unsubscr...@freebsd.org"
