2019-05-24target/riscv: Add a base 32 and 64 bit CPUAlistair Francis1-2/+2
At the same time deprecate the ISA string CPUs. It is dobtful anyone specifies the CPUs, but we are keeping them for the Spike machine (which is about to be depreated) so we may as well just mark them as deprecated.

QEMU model of the GPIO device on the SiFive E300 series SOCs. The pins are not used by a board definition yet, however this implementation can already be used to trigger GPIO interrupts from the software by configuring a pin as both output and input.

2019-05-20pci: Simplify pci_bus_is_root()David Gibson2-2/+11
pci_bus_is_root() currently relies on a method in the PCIBusClass. But it's always known if a PCI bus is a root bus when we create it, so using a dynamic method is overkill. This replaces it with an IS_ROOT bit in a new flags field, which is set on root buses and otherwise clear. As a bonus this removes the special is_root logic from pci_expander_bridge, since it already creates its bus as a root bus.

Eventually, we want to make sure that all parents and all children of a node are in the same AioContext as the node itself. This means that changing the AioContext may fail because one of the other involved parties (e.g. a guest device that was configured with an iothread) cannot allow switching to a different AioContext. Introduce a set of functions that allow to first check whether all involved nodes can switch to a new context and only then do the actual switch. The check recursively covers children and parents.

2019-05-17ioapic: allow buggy guests mishandling level-triggered interrupts to make ↵Vitaly Kuznetsov1-0/+3
progress It was found that Hyper-V 2016 on KVM in some configurations (q35 machine + piix4-usb-uhci) hangs on boot. Root-cause was that one of Hyper-V level-triggered interrupt handler performs EOI before fixing the cause of the interrupt. This results in IOAPIC keep re-raising the level-triggered interrupt after EOI because irq-line remains asserted. Gory details: https://www.spinics.net/lists/kvm/msg184484.html (the whole thread). Turns out we were dealing with similar issues before; in-kernel IOAPIC implementation has commit 184564efae4d ("kvm: ioapic: conditionally delay irq delivery duringeoi broadcast") which describes a very similar issue. Steal the idea from the above mentioned commit for IOAPIC implementation in QEMU. SUCCESSIVE_IRQ_MAX_COUNT, delay and the comment are borrowed as well.

2019-05-17vhost_net: don't set backend for the uninitialized virtqueueJason Wang1-0/+1
We used to set backend unconditionally, this won't work for some guests (e.g windows driver) who may not initialize all virtqueues. For kernel backend, this will fail since it may try to validate the rings during setting backend. Fixing this by simply skipping the backend set when we find desc is not ready.

2019-05-10tcg: Use tlb_fill probe from tlb_vaddr_to_hostRichard Henderson1-40/+10
Most of the existing users would continue around a loop which would fault the tlb entry in via a normal load/store. But for AArch64 SVE we have an existing emulation bug wherein we would mark the first element of a no-fault vector load as faulted (within the FFR, not via exception) just because we did not have its address in the TLB. Now we can properly only mark it as faulted if there really is no valid, readable translation, while still not raising an exception. (Note that beyond the first element of the vector, the hardware may report a fault for any reason whatsoever; with at least one element loaded, forward progress is guaranteed.)
