[PATCH v12 01/15] ui & main loop: Redesign of system-specific main thread event handling

macOS's Cocoa event handling must be done on the initial (main) thread of the process. Furthermore, if library or application code uses libdispatch, the main dispatch queue must be handling events on the main thread as well. So far, this has affected Qemu in both the Cocoa and SDL UIs, although in

[PATCH v12 11/15] hw/vmapple/bdif: Introduce vmapple backdoor interface

From: Alexander Graf The VMApple machine exposes AUX and ROOT block devices (as well as USB OTG emulation) via virtio-pci as well as a special, simple backdoor platform device. This patch implements this backdoor platform device to the best of my understanding. I left out any USB OTG parts; they

[PATCH v12 00/15] macOS PV Graphics and new vmapple machine type

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

[PATCH v12 12/15] hw/vmapple/cfg: Introduce vmapple cfg region

From: Alexander Graf Instead of device tree or other more standardized means, VMApple passes platform configuration to the first stage boot loader in a binary encoded format that resides at a dedicated RAM region in physical address space. This patch models this configuration space as a qdev dev

[PATCH v12 03/15] hw/display/apple-gfx: Adds PCI implementation

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. Signed-off-by: Phil Dennis-Jordan Reviewed-by: Ak

[PATCH v12 05/15] MAINTAINERS: Add myself as maintainer for apple-gfx, reviewer for HVF

I'm happy to take responsibility for the macOS PV graphics code. As HVF patches don't seem to get much attention at the moment, I'm also adding myself as designated reviewer for HVF and x86 HVF to try and improve that. I anticipate that the resulting workload should be covered by the funding I'm r

[PATCH v12 15/15] hw/vmapple/vmapple: Add vmapple machine type

From: Alexander Graf 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. This

[PATCH v12 04/15] hw/display/apple-gfx: Adds configurable mode list

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

[PATCH v12 13/15] hw/vmapple/virtio-blk: Add support for apple virtio-blk

From: Alexander Graf Apple has its own virtio-blk PCI device ID where it deviates from the official virtio-pci spec slightly: It puts a new "apple type" field at a static offset in config space and introduces a new barrier command. This patch first creates a mechanism for virtio-blk downstream c

From: Alexander Graf 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. Signed-off-by: Alexander Graf Signed-off-by: Phil Dennis-Jo

[PATCH v12 09/15] gpex: Allow more than 4 legacy IRQs

From: Alexander Graf 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.
