2021-02-10multi-process: create IOHUB object to handle irqJagannathan Raman1-0/+2
IOHUB object is added to manage PCI IRQs. It uses KVM_IRQFD ioctl to create irqfd to injecting PCI interrupts to the guest. IOHUB object forwards the irqfd to the remote process. Remote process uses this fd to directly send interrupts to the guest, bypassing QEMU.

2021-02-10multi-process: Synchronize remote memoryJagannathan Raman1-0/+2
Add ProxyMemoryListener object which is used to keep the view of the RAM in sync between QEMU and remote process. A MemoryListener is registered for system-memory AddressSpace. The listener sends SYNC_SYSMEM message to the remote process when memory listener commits the changes to memory, the remote process receives the message and processes it in the handler for SYNC_SYSMEM message.

The microblaze kernel sometimes gets stuck during boot (ca. 1 out of 200 times), so we disabled the corresponding acceptance tests some months ago. However, it's likely better to check that the kernel is still starting than to not testing it at all anymore.

2021-02-05cpu: tcg_ops: move to tcg-cpu-ops.h, keep a pointer in CPUClassClaudio Fontana1-0/+1
we cannot in principle make the TCG Operations field definitions conditional on CONFIG_TCG in code that is included by both common_ss and specific_ss modules. Therefore, what we can do safely to restrict the TCG fields to TCG-only builds, is to move all tcg cpu operations into a separate header file, which is only included by TCG, target-specific code. This leaves just a NULL pointer in the cpu.h for the non-TCG builds. This also tidies up the code in all targets a bit, having all TCG cpu operations neatly contained by a dedicated data struct.

2021-02-02MAINTAINERS: Add Vladimir as co-maintainer for Block JobsVladimir Sementsov-Ogievskiy1-0/+10
I'm developing Qemu backup for several years, and finally new backup architecture, including block-copy generic engine and backup-top filter landed upstream, great thanks to reviewers and especially to Max Reitz! I also have plans of moving other block-jobs onto block-copy, so that we finally have one generic block copying path, fast and well-formed. So, now I suggest to bring all parts of backup architecture into "Block Jobs" subsystem (actually, aio_task is shared with qcow2 and qemu-co-shared-resource can be reused somewhere else, but I'd keep an eye on them in context of block-jobs) and add myself as co-maintainer.

2021-01-06ppc: Convert PPC UIC to a QOM devicePeter Maydell1-0/+2
Currently the PPC UIC ("Universal Interrupt Controller") is implemented as a non-QOM device in ppc4xx_devs.c. Convert it to a proper QOM device in hw/intc. The ppcuic_init() function is retained for the moment with its current interface; in subsequent commits this will be tidied up to avoid the allocation of an irq array. This conversion adds VMState support. It leaves the LOG_UIC() macro as-is to maximise the extent to which this is simply code-movement rather than a rewrite (in new code it would be better to use tracepoints). The default property values for dcr-base and use-vectors are set to match those use by most of our boards with a UIC.

2021-01-04hw/mips: Add Loongson-3 machine supportHuacai Chen1-0/+1
Add Loongson-3 based machine support, it use liointc as the interrupt controler and use GPEX as the pci controller. Currently it can work with both TCG and KVM. As the machine model is not based on any exiting physical hardware, the name of the machine is "loongson3-virt". It may be superseded in future by a real machine model. If this happens, then a regular deprecation procedure shall occur for "loongson3-virt" machine. We now already have a full functional Linux kernel (based on Linux-5.4.x LTS) here: https://github.com/chenhuacai/linux Of course the upstream kernel is also usable (the kvm host side and guest side have both been upstream in Linux-5.9): https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git How to use QEMU/Loongson-3? 1, Download kernel source from the above URL; 2, Build a kernel with arch/mips/configs/loongson3_defconfig; 3, Boot a Loongson-3A4000 host with this kernel (for KVM mode); 4, Build QEMU-master with this patchset; 5, modprobe kvm (only necessary for KVM mode); 6, Use QEMU with TCG: qemu-system-mips64el -M loongson3-virt,accel=tcg -cpu Loongson-3A1000 -kernel <path_to_kernel> -append ... Use QEMU with KVM: qemu-system-mips64el -M loongson3-virt,accel=kvm -cpu Loongson-3A4000 -kernel <path_to_kernel> -append ... The "-cpu" parameter is optional here and QEMU will use the correct type for TCG/KVM automatically.
