If a host chooses to use the SQHD "hint" in the CQE to know if there is
room in the submission queue for additional commands, it may result in a
situation where there are not enough internal resources (struct

MacOS provides a framework (library) that allows any vmm to implement a
paravirtualized 3d graphics passthrough to the host metal stack called
ParavirtualizedGraphics.Framework (PVG). The library abstracts away
almost every aspect of the paravirtualized device model and only provides

Some boards such as vmapple don't do real legacy PCI IRQ swizzling.
Instead, they just keep allocating more board IRQ lines for each new
legacy IRQ. Let's support that mode by giving instantiators a new
"nr_irqs" property they can use to support more than 4 legacy IRQ lines.
This change adds a property 'display_modes' on the graphics device
which permits specifying a list of display modes. (screen resolution
and refresh rate)
The property is an array of a custom type to make the syntax slightly
less awkward to use, for example:
-device '{"driver":"apple-gfx-pci", "di
This patch set introduces a new ARM and macOS HVF specific machine type
called "vmapple", as well as a family of display devices based on the
ParavirtualizedGraphics.framework in macOS. One of the display adapter
variants, apple-gfx-mmio, is required for the new machine type, while
apple-gfx-pci ca
This change wires up the PCI variant of the paravirtualised
graphics device, mainly useful for x86-64 macOS guests, implemented
by macOS's ParavirtualizedGraphics.framework. It builds on code
shared with the vmapple/mmio variant of the PVG device.

MacOS unconditionally disables interrupts of the physical timer on boot
and then continues to use the virtual one. We don't really want to support
a full physical timer emulation, so let's just ignore those writes.

I'm happy to take responsibility for the macOS PV graphics code. As

Apple defines a new "vmapple" machine type as part of its proprietary
macOS Virtualization.Framework vmm. This machine type is similar to the
virt one, but with subtle differences in base devices, a few special
vmapple device additions and a vastly different boot chain.

Apple has its own virtio-blk PCI device ID where it deviates from the

macOS's Cocoa event handling must be done on the initial (main) thread
