The edu spec says the MMIO area can be accessed by 64-bit. However currently the 'max_access_size' is not so the MMIO access dispatch can only access 32-bit one time. This patch fixes this to respect the spec.

The CPUID.01H:ECX[bit 3] ought to mirror the value of the MSR IA32_MISC_ENABLE MWAIT bit and as userspace has control of them both, it is userspace's job to configure both bits to match on the initial setup.

Currently, -accel help shows all possible accelerators regardless if they are enabled in the binary or not. That is a different semantic from -cpu and -machine helps, for example. So this change makes it to list only the accelerators which support is compiled in the binary target. Note that it does not check if the accelerator is enabled in the host, so the help message's header was rewritten to emphasize that. Also qtest is not displayed given that it is used for internal testing purpose only.

ppc patch queue 2019-05-29 Next pull request against qemu-4.1. Highlights: * KVM accelerated support for the XIVE interrupt controller in PAPR guests * A number of TCG vector fixes * Fixes for the PReP / 40p machine * Improvements to make check-tcg test coverage Other than that it's just a bunch of assorted fixes, cleanups and minor improvements. This supersedes both the pull request dated 2019-05-21 and the one dated 2019-05-22. I've dropped one hunk which I think may have caused the check-tcg failure that Peter saw (by enabling the ppc64abi32 build, which I think has been broken for ages).

Add a base class that is common to virtio-gpu and vhost-user-gpu devices. The VirtIOGPUBase base class provides common functionalities necessary for both virtio-gpu and vhost-user-gpu: - common configuration (max-outputs, initial resolution, flags) - virtio device initialization, including queue setup - device pre-conditions checks (iommu) - migration blocker - virtio device callbacks - hooking up to qemu display subsystem - a few common helper functions to reset the device, retrieve display informations - a class callback to unblock the rendering (for GL updates) What is left to the virtio-gpu subdevice to take care of, in short, are all the virtio queues handling, command processing and migration.

Add a new vhost-user message to give a unix socket to a vhost-user backend for GPU display updates. Back when I started that work, I added a new GPU channel because the vhost-user protocol wasn't bidirectional. Since then, there is a vhost-user-slave channel for the slave to send requests to the master. We could extend it with GPU messages. However, the GPU protocol is quite orthogonal to vhost-user, thus I chose to have a new dedicated channel. See vhost-user-gpu.rst for the protocol details.

PRD (Processor recovery diagnostics) is a service available on OpenPower systems. The opal-prd daemon initializes the PowerPC Processor through the XSCOM bus and then waits for hardware diagnostic events.

Newer skiboots (after 6.3) support QEMU platforms that have characteristics closer to real OpenPOWER systems. The CPU type is used to define the BMC drivers: Aspeed AST2400 for POWER8 processors and AST2500 for POWER9s. Advertise the new platform property names, "qemu,powernv8" and "qemu,powernv9", using the CPU type chosen for the QEMU PowerNV machine. Also, advertise the original platform name "qemu,powernv" in case of POWER8 processors for compatibility with older skiboots.
