2023-01-08include: Include headers where neededMarkus Armbruster
A number of headers neglect to include everything they need. They compile only if the headers they need are already included from elsewhere. Fix that.

2023-01-08include/hw/pci: Split pci_device.h off pci.hMarkus Armbruster
PCIDeviceClass and PCIDevice are defined in pci.h. Many users of the header don't actually need them. Similar structs live in their own headers: PCIBusClass and PCIBus in pci_bus.h, PCIBridge in pci_bridge.h, PCIHostBridgeClass and PCIHostState in pci_host.h, PCIExpressHost in pcie_host.h, and PCIERootPortClass, PCIEPort, and PCIESlot in pcie_port.h. Move PCIDeviceClass and PCIDeviceClass to new pci_device.h, along with the code that needs them. Adjust include directives. This also enables the next commit.

virtio.c is big enough, extract more QMP related code to virtio-qmp.c. To do so, expose qmp_find_virtio_device() and declar virtio_list in the internal virtio-qmp.h header. Note we have to leave qmp_x_query_virtio_queue_status() and qmp_x_query_virtio_queue_element(), because they access VirtQueue internal fields, and VirtQueue is only declared within virtio.c.

2023-01-08vhost-user: Fix the virtio features negotiation flawHyman Huang(黄勇)
This patch aims to fix unexpected negotiation features for vhost-user netdev interface. When openvswitch reconnect Qemu after an unexpected disconnection and Qemu therefore start the vhost_dev, acked_features field in vhost_dev is initialized with value fetched from acked_features field in NetVhostUserState, which should be up-to-date at that moment but Qemu could not make it actually during the time window of virtio features negotiation. So we save the acked_features right after being configured by guest virtio driver so it can be used to restore acked_features field in vhost_dev correctly.

The pending register upper limit is currently set to plic->num_sources >> 3, which is wrong, e.g.: considering plic->num_sources is 7, the upper limit becomes 0 which fails the range check if reading the pending register at pending_base.

2023-01-06hw/intc: sifive_plic: Change "priority-base" to start from interrupt source 0Bin Meng
At present the SiFive PLIC model "priority-base" expects interrupt priority register base starting from source 1 instead source 0, that's why on most platforms "priority-base" is set to 0x04 except 'opentitan' machine. 'opentitan' should have set "priority-base" to 0x04 too. Note the irq number calculation in sifive_plic_{read,write} is correct as the codes make up for the irq number by adding 1. Let's simply update "priority-base" to start from interrupt source 0 and add a comment to make it crystal clear.

2023-01-06hw/riscv: virt: Fix the value of "riscv, ndev" in the dtbBin Meng
Commit 28d8c281200f ("hw/riscv: virt: Add optional AIA IMSIC support to virt machine") changed the value of VIRT_IRQCHIP_NUM_SOURCES from 127 to 53, which is VIRTIO_NDEV and also used as the value of "riscv,ndev" property in the dtb. Unfortunately this is wrong as VIRT_IRQCHIP_NUM_SOURCES should include interrupt source 0 but "riscv,ndev" does not. While we are here, we also fix the comments of platform bus irq range which is now "64 to 96", but should be "64 to 95", introduced since commit 1832b7cb3f64 ("hw/riscv: virt: Create a platform bus").
