("[PATCH v2 0/4] hw/pci: Convert rom_bar into OnOffAuto")I submitted a RFC series[1] to add support for SR-IOV emulation to virtio-net-pci. During the development of the series, I fixed some trivial bugs and made improvements that I think are independently useful. This series extracts those fixes and improvements from the RFC series.

I found SR-IOV devices, which are multifunction devices, are not supposed to work at all with s390x on QEMU. - Link to v12: https://lore.kernel.org/r/20240804-reuse-v12-0-d3930c411...@daynix.com Changes in v12: - Changed to ignore invalid PCI_SRIOV_NUM_VF writes as done for PCI_SRIOV_CTRL_VFE. - Updated the message for patch "hw/pci: Use -1 as the default value for rombar".

Tsirkin) - Added patch "pcie_sriov: Ensure VF function number does not overflow" to fix abortion with wrong PF addr. - Link to v8: https://lore.kernel.org/r/20240228-reuse-v8-0-282660281...@daynix.com Changes in v8: - Clarified that "hw/pci: Replace -1 with UINT32_MAX for romsize" is not a bug fix. (Markus Armbruster) - Squashed patch "vfio: Avoid inspecting option QDict for rombar" into "hw/pci: Determine if rombar is explicitly enabled". (Markus Armbruster) - Noted the minor semantics change for patch "hw/pci: Determine if rombar is explicitly enabled".

(Michael S. Tsirkin) - Noted the impact on the guest of patch "pcie_sriov: Do not reset NumVFs after unregistering VFs". (Michael S. Tsirkin) - Changed to use pcie_sriov_num_vfs(). - Restored pci_set_power() and changed it to call pci_set_enabled() only for PFs with an expalanation. (Michael S.
