2023-01-06hw/riscv: sifive_e: Fix the number of interrupt sources of PLICBin Meng
Per chapter 10 in Freedom E310 manuals [1][2][3], E310 G002 and G003 supports 52 interrupt sources while G000 supports 51 interrupt sources. We use the value of G002 and G003, so it is 53 (including source 0).

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.

2022-12-16hw/input/ps2.c: Convert TYPE_PS2_{KBD, MOUSE}_DEVICE to 3-phase resetPeter Maydell
Convert the child classes TYPE_PS2_KBD_DEVICE and TYPE_PS2_MOUSE_DEVICE to the 3-phase reset system. This allows us to stop using the old device_class_set_parent_reset() function. We don't need to register an 'exit' phase function for the subclasses, because they have no work to do in that phase. Passing NULL to resettable_class_set_parent_phases() will result in the parent class method being called for that phase, so we don't need to register a function purely to chain to the parent 'exit' phase function.

2022-12-15hw/misc: Move some arm-related files from specific_ss into softmmu_ssThomas Huth
The header target/arm/kvm-consts.h checks CONFIG_KVM which is marked as poisoned in common code, so the files that include this header have to be added to specific_ss and recompiled for each, qemu-system-arm and qemu-system-aarch64. However, since the kvm headers are only optionally used in kvm-constants.h for some sanity checks, we can additionally check the NEED_CPU_H macro first to avoid the poisoned CONFIG_KVM macro, so kvm-constants.h can also be used from "common" files (without the sanity checks - which should be OK since they are still done from other target-specific files instead). This way, and by adjusting some other include statements in the related files here and there, we can move some files from specific_ss into softmmu_ss, so that they only need to be compiled once during the build process.

2022-12-15s390x/pci: reset ISM passthrough devices on shutdown and system resetMatthew Rosato
ISM device firmware stores unique state information that can can cause a wholesale unmap of the associated IOMMU (e.g. when we get a termination signal for QEMU) to trigger firmware errors because firmware believes we are attempting to invalidate entries that are still in-use by the guest OS (when in fact that guest is in the process of being terminated or rebooted). To alleviate this, register both a shutdown notifier (for unexpected termination cases e.g. virsh destroy) as well as a reset callback (for cases like guest OS reboot). For each of these scenarios, trigger PCI device reset; this is enough to indicate to firmware that the IOMMU is no longer in-use by the guest OS, making it safe to invalidate any associated IOMMU entries.

2022-12-15s390x/pci: shrink DMA aperture to be bound by vfio DMA limitMatthew Rosato
Currently, s390x-pci performs accounting against the vfio DMA limit and triggers the guest to clean up mappings when the limit is reached. Let's go a step further and also limit the size of the supported DMA aperture reported to the guest based upon the initial vfio DMA limit reported for the container (if less than than the size reported by the firmware/host zPCI layer). This avoids processing sections of the guest DMA table during global refresh that, for common use cases, will never be used anway, and makes exhausting the vfio DMA limit due to mismatch between guest aperture size and host limit far less likely and more indicitive of an error.

Convert the TYPE_ARM_SMMUV3 device to 3-phase reset. The legacy reset method doesn't do anything that's invalid in the hold phase, so the conversion only requires changing it to a hold phase method, and using the 3-phase versions of the "save the parent reset method and chain to it" code.

2022-12-15hw/arm/virt: Add 'compact-highmem' propertyGavin Shan
After the improvement to high memory region address assignment is applied, the memory layout can be changed, introducing possible migration breakage. For example, VIRT_HIGH_PCIE_MMIO memory region is disabled or enabled when the optimization is applied or not, with the following configuration. The configuration is only achievable by modifying the source code until more properties are added to allow users selectively disable those high memory regions. pa_bits = 40; vms->highmem_redists = false; vms->highmem_ecam = false; vms->highmem_mmio = true; # qemu-system-aarch64 -accel kvm -cpu host \ -machine virt-7.2,compact-highmem={on, off} \ -m 4G,maxmem=511G -monitor stdio Region compact-highmem=off compact-highmem=on ---------------------------------------------------------------- MEM [1GB 512GB] [1GB 512GB] HIGH_GIC_REDISTS2 [512GB 512GB+64MB] [disabled] HIGH_PCIE_ECAM [512GB+256MB 512GB+512MB] [disabled] HIGH_PCIE_MMIO [disabled] [512GB 1TB] In order to keep backwords compatibility, we need to disable the optimization on machine, which is virt-7.1 or ealier than it. It means the optimization is enabled by default from virt-7.2. Besides, 'compact-highmem' property is added so that the optimization can be explicitly enabled or disabled on all machine types by users.

2022-12-15hw/arm/virt: Improve high memory region address assignmentGavin Shan
There are three high memory regions, which are VIRT_HIGH_REDIST2, VIRT_HIGH_PCIE_ECAM and VIRT_HIGH_PCIE_MMIO. Their base addresses are floating on highest RAM address. However, they can be disabled in several cases. (1) One specific high memory region is likely to be disabled by code by toggling vms->highmem_{redists, ecam, mmio}. (2) VIRT_HIGH_PCIE_ECAM region is disabled on machine, which is 'virt-2.12' or ealier than it. (3) VIRT_HIGH_PCIE_ECAM region is disabled when firmware is loaded on 32-bits system. (4) One specific high memory region is disabled when it breaks the PA space limit. The current implementation of virt_set_{memmap, high_memmap}() isn't optimized because the high memory region's PA space is always reserved, regardless of whatever the actual state in the corresponding vms->highmem_{redists, ecam, mmio} flag. In the code, 'base' and 'vms->highest_gpa' are always increased for case (1), (2) and (3). It's unnecessary since the assigned PA space for the disabled high memory region won't be used afterwards. Improve the address assignment for those three high memory region by skipping the address assignment for one specific high memory region if it has been disabled in case (1), (2) and (3). The memory layout may be changed after the improvement is applied, which leads to potential migration breakage. So 'vms->highmem_compact' is added to control if the improvement should be applied. For now, 'vms->highmem_compact' is set to false, meaning that we don't have memory layout change until it becomes configurable through property 'compact-highmem' in next patch.
