Convert the fprintf() messages in kvm_mips_update_state() to use warn_report() as they aren't errors, but are just warnings.

Convert all the single line uses of fprintf(stderr, "warning:"..."\n"... to use warn_report() instead. This helps standardise on a single method of printing warnings to the user. All of the warnings were changed using this command: find ./* -type f -exec sed -i \ 's|fprintf(.*".*warning[,:] \(.*\)\\n"\(.*\));|warn_report("\1"\2);|Ig' \ {} + Some of the lines were manually edited to reduce the line length to below 80 charecters. The #include lines were manually updated to allow the code to compile.

We've currently got 18 architectures in QEMU, and thus 18 target-xxx folders in the root folder of the QEMU source tree. More architectures (e.g. RISC-V, AVR) are likely to be included soon, too, so the main folder of the QEMU sources slowly gets quite overcrowded with the target-xxx folders. To disburden the main folder a little bit, let's move the target-xxx folders into a dedicated target/ folder, so that target-xxx/ simply becomes target/xxx/ instead.

Adding two hooks to be notified when adding/removing msi routes. There are two kinds of MSI routes: - in kvm_irqchip_add_irq_route(): before assigning IRQFD. Used by vhost, vfio, etc. - in kvm_irqchip_send_msi(): when sending direct MSI message, if direct MSI not allowed, we will first create one MSI route entry in the kernel, then trigger it. This patch only hooks the first one (irqfd case). We do not need to take care for the 2nd one, since it's only used by QEMU userspace (kvm-apic) and the messages will always do in-time translation when triggered. While we need to note them down for the 1st one, so that we can notify the kernel when cache invalidation happens. Also, we do not hook IOAPIC msi routes (we have explicit notifier for IOAPIC to keep its cache updated). We only need to care about irqfd users.

Support the new KVM_CAP_MIPS_MSA capability, which allows MIPS SIMD Architecture (MSA) to be exposed to the KVM guest. The capability is enabled if the guest core has MSA according to its Config3 register. Various config bits are now writeable so that KVM is aware of the configuration (Config3.MSAP) and so that QEMU can save/restore the guest modifiable bits (Config5.MSAEn). The MSACSR/MSAIR registers and the MSA vector registers are now saved/restored. Since the FP registers are a subset of the vector registers, they are omitted if the guest has MSA.

Replace the uint64 softfloat-specific typedef with uint64_t. This change was made with find include fpu target-* -name '*.[ch]' | xargs sed -i -e 's/\buint64\b/uint64_t/g' together with manual removal of the typedef definition, and manual undoing of some mis-hits where macro arguments were being used for token pasting rather than as a type. Note that the target-mips/kvm.c and target-s390x/kvm.c changes are fixing code that should not have been using the uint64 type in the first place.

This opens the path to get rid of the iothread lock on vmexits in KVM mode. On x86, the in-kernel irqchips has to be used because we otherwise need to synchronize APIC and other per-cpu state accesses that could be changed concurrently. Regarding pre/post-run callbacks, s390x and ARM should be fine without specific locking as the callbacks are empty. MIPS and POWER require locking for the pre-run callback. For the handle_exit callback, it is non-empty in x86, POWER and s390. Some POWER cases could do without the locking, but it is left in place for now.
