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.

2023-01-06hw/{misc, riscv}: pfsoc: add system controller as unimplementedConor Dooley
The system controller on PolarFire SoC is access via a mailbox. The control registers for this mailbox lie in the "IOSCB" region & the interrupt is cleared via write to the "SYSREG" region. It also has a QSPI controller, usually connected to a flash chip, that is used for storing FPGA bitstreams and used for In-Application Programming (IAP). Linux has an implementation of the system controller, through which the hwrng is accessed, leading to load/store access faults. Add the QSPI as unimplemented and a very basic (effectively unimplemented) version of the system controller's mailbox. Rather than purely marking the regions as unimplemented, service the mailbox requests by reporting failures and raising the interrupt so a guest can better handle the lack of support.

2023-01-06hw/riscv: pfsoc: add missing FICs as unimplementedConor Dooley
The Fabric Interconnect Controllers provide interfaces between the FPGA fabric and the core complex. There are 5 FICs on PolarFire SoC, numbered 0 through 4. FIC2 is an AXI4 slave interface from the FPGA fabric and does not show up on the MSS memory map. FIC4 is dedicated to the User Crypto Processor and does not show up on the MSS memory map either. FIC 0, 1 & 3 do show up in the MSS memory map and neither FICs 0 or 1 are represented in QEMU, leading to load access violations while booting Linux for Icicle if PCIe is enabled as the root port is connected via either FIC 0 or 1.

2023-01-06hw/misc: pfsoc: add fabric clocks to ioscbConor Dooley
On PolarFire SoC, some peripherals (eg the PCI root port) are clocked by "Clock Conditioning Circuitry" in the FPGA. The specific clock depends on the FPGA bitstream & can be locked to one particular {D,P}LL - in the Icicle Kit Reference Design v2022.09 or later this is/will be the case. Linux v6.1+ will have a driver for this peripheral and devicetrees that previously relied on "fixed-frequency" clock nodes have been switched over to clock-controller nodes. The IOSCB region is represented in QEMU, but the specific region of it that the CCCs occupy has not so v6.1-rcN kernels fail to boot in QEMU. Add the regions as unimplemented so that the status-quo in terms of boot is maintained.
