Supersedes: <20240714-rombar-v2-0-af1504ef55de@daynix.com> ("[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. [1]: https://patchew.org/QEMU/20231210-sriov-v2-0-b959e8a6dfaf@daynix.com/ Signed-off-by: Akihiko Odaki <akihiko.odaki@daynix.com> --- Changes in v13: - Added patch "s390x/pci: Check for multifunction after device realization". 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-d3930c4111b2@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". (Markus Armbruster) - Link to v11: https://lore.kernel.org/r/20240802-reuse-v11-0-fb83bb8c19fb@daynix.com Changes in v11: - Rebased. - Dropped patch "hw/pci: Convert rom_bar into OnOffAuto". - Added patch "hw/pci: Use -1 as the default value for rombar". - Added for-9.2 to give a testing period for possible breakage with libvirt/s390x. - Link to v10: https://lore.kernel.org/r/20240627-reuse-v10-0-7ca0b8ed3d9f@daynix.com Changes in v10: - Added patch "hw/ppc/spapr_pci: Do not reject VFs created after a PF". - Added patch "hw/ppc/spapr_pci: Do not create DT for disabled PCI device". - Added patch "hw/pci: Convert rom_bar into OnOffAuto". - Dropped patch "hw/pci: Determine if rombar is explicitly enabled". - Dropped patch "hw/qdev: Remove opts member". - Link to v9: https://lore.kernel.org/r/20240315-reuse-v9-0-67aa69af4d53@daynix.com Changes in v9: - Rebased. - Restored '#include "qapi/error.h"' (Michael S. 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-v8-0-282660281e60@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". (Markus Armbruster) - Link to v7: https://lore.kernel.org/r/20240224-reuse-v7-0-29c14bcb952e@daynix.com Changes in v7: - Replaced -1 with UINT32_MAX when expressing uint32_t. (Markus Armbruster) - Added patch "hw/pci: Replace -1 with UINT32_MAX for romsize". - Link to v6: https://lore.kernel.org/r/20240220-reuse-v6-0-2e42a28b0cf2@daynix.com Changes in v6: - Fixed migration. - Added patch "pcie_sriov: Do not manually unrealize". - Restored patch "pcie_sriov: Release VFs failed to realize" that was missed in v5. - Link to v5: https://lore.kernel.org/r/20240218-reuse-v5-0-e4fc1c19b5a9@daynix.com Changes in v5: - Added patch "hw/pci: Always call pcie_sriov_pf_reset()". - Added patch "pcie_sriov: Reset SR-IOV extended capability". - Removed a reference to PCI_SRIOV_CTRL_VFE in hw/nvme. (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. Tsirkin) - Reordered patches. - Link to v4: https://lore.kernel.org/r/20240214-reuse-v4-0-89ad093a07f4@daynix.com Changes in v4: - Reverted the change to pci_rom_bar_explicitly_enabled(). (Michael S. Tsirkin) - Added patch "pcie_sriov: Do not reset NumVFs after unregistering VFs". - Added patch "hw/nvme: Refer to dev->exp.sriov_pf.num_vfs". - Link to v3: https://lore.kernel.org/r/20240212-reuse-v3-0-8017b689ce7f@daynix.com Changes in v3: - Extracted patch "hw/pci: Use -1 as a default value for rombar" from patch "hw/pci: Determine if rombar is explicitly enabled" (Philippe Mathieu-Daudé) - Added an audit result of PCIDevice::rom_bar to the message of patch "hw/pci: Use -1 as a default value for rombar" (Philippe Mathieu-Daudé) - Link to v2: https://lore.kernel.org/r/20240210-reuse-v2-0-24ba2a502692@daynix.com Changes in v2: - Reset after enabling a function so that NVMe VF state gets updated. - Link to v1: https://lore.kernel.org/r/20240203-reuse-v1-0-5be8c5ce6338@daynix.com --- Akihiko Odaki (12): hw/pci: Rename has_power to enabled hw/ppc/spapr_pci: Do not create DT for disabled PCI device hw/ppc/spapr_pci: Do not reject VFs created after a PF s390x/pci: Check for multifunction after device realization pcie_sriov: Do not manually unrealize pcie_sriov: Ensure VF function number does not overflow pcie_sriov: Reuse SR-IOV VF device instances pcie_sriov: Release VFs failed to realize pcie_sriov: Remove num_vfs from PCIESriovPF pcie_sriov: Register VFs after migration hw/pci: Use -1 as the default value for rombar hw/qdev: Remove opts member docs/pcie_sriov.txt | 8 ++- include/hw/pci/pci.h | 2 +- include/hw/pci/pci_device.h | 19 ++++- include/hw/pci/pcie_sriov.h | 9 +-- include/hw/qdev-core.h | 4 -- hw/core/qdev.c | 1 - hw/net/igb.c | 13 +++- hw/nvme/ctrl.c | 24 ++++--- hw/pci/pci.c | 23 +++--- hw/pci/pci_host.c | 4 +- hw/pci/pcie_sriov.c | 165 +++++++++++++++++++++++++------------------- hw/ppc/spapr_pci.c | 8 ++- hw/s390x/s390-pci-bus.c | 14 ++-- hw/vfio/pci.c | 5 +- system/qdev-monitor.c | 12 ++-- hw/pci/trace-events | 2 +- 16 files changed, 187 insertions(+), 126 deletions(-) --- base-commit: 31669121a01a14732f57c49400bc239cf9fd505f change-id: 20240129-reuse-faae22b11934 Best regards,
