This is a respin of Philippe's original series here: https://lore.kernel.org/qemu-devel/20250501210456.89071-1-philmd@linaro.org The following three patches still need a review: - hw/pci/pcie: Remove QEMU_PCIE_EXTCAP_INIT definition - hw/i386/x86-iommu: Remove X86IOMMUState::pt_supported field - tests/qtest/test-x86-cpuid-compat: Remove the test with the i440fx-2.9 machine Changes in v2: - Rebased all patches to current master, and fixed the contextual conflicts - Added Igor's Reviewed-bys - Dropped the "hw/southbridge/ich9: Remove ICH9_LPC_SMI_F_BROADCAST_BIT definition" patch since the code is still required (the guest can decide whether to use this feature or not) - Dropped the two "hw/nvram/fw_cfg" patches since Igor mentioned that it still might be useful to keep this configuration knob - Fix "hw/pci/pcie: Remove QEMU_PCIE_EXTCAP_INIT definition" according to Igor's review - Adjusted "hw/i386/x86-iommu: Remove X86IOMMUState::pt_supported field": The problematic hunk has already been merged in upstream, so I dropped it from this patch. - Added the final patch to drop a qtest that required this machine Philippe Mathieu-Daudé (15): hw/i386/pc: Remove deprecated pc-q35-2.8 and pc-i440fx-2.8 machines hw/i386/pc: Remove pc_compat_2_8[] array hw/i386/kvm: Remove KVMClockState::mach_use_reliable_get_clock field hw/core/machine: Remove hw_compat_2_8[] array hw/block/pflash: Remove PFlashCFI01::old_multiple_chip_handling field hw/pci/pcie: Remove QEMU_PCIE_EXTCAP_INIT definition hw/virtio/virtio-pci: Remove VIRTIO_PCI_FLAG_INIT_DEVERR definition hw/virtio/virtio-pci: Remove VIRTIO_PCI_FLAG_INIT_LNKCTL definition hw/virtio/virtio-pci: Remove VIRTIO_PCI_FLAG_INIT_PM definition hw/i386/pc: Remove deprecated pc-q35-2.9 and pc-i440fx-2.9 machines hw/i386/pc: Remove pc_compat_2_9[] array hw/core/machine: Remove hw_compat_2_9[] array hw/net/virtio-net: Remove VirtIONet::mtu_bypass_backend field hw/pci-bridge/gen_pcie_rp: Remove GenPCIERootPort::migrate_msix field hw/i386/x86-iommu: Remove X86IOMMUState::pt_supported field Thomas Huth (1): tests/qtest/test-x86-cpuid-compat: Remove the test with the i440fx-2.9 machine include/hw/core/boards.h | 6 ----- include/hw/i386/pc.h | 6 ----- include/hw/i386/x86-iommu.h | 1 - include/hw/pci/pci.h | 2 -- include/hw/virtio/virtio-net.h | 1 - include/hw/virtio/virtio-pci.h | 12 ---------- hw/block/pflash_cfi01.c | 14 +++--------- hw/core/machine.c | 22 ------------------ hw/i386/intel_iommu.c | 13 ++--------- hw/i386/kvm/clock.c | 18 --------------- hw/i386/pc.c | 14 ------------ hw/i386/pc_piix.c | 18 --------------- hw/i386/pc_q35.c | 18 --------------- hw/i386/x86-iommu.c | 1 - hw/net/virtio-net.c | 8 ++----- hw/pci-bridge/gen_pcie_root_port.c | 16 ++----------- hw/pci/pci.c | 2 -- hw/pci/pcie.c | 6 ++--- hw/virtio/virtio-pci.c | 35 ++++++++--------------------- tests/qtest/test-x86-cpuid-compat.c | 11 --------- 20 files changed, 20 insertions(+), 204 deletions(-) -- 2.53.0
