2017-09-14xlnx-zcu102: Manually create the machinesAlistair Francis
In preperation for future work let's manually create the Xilnx machines. This will allow us to set properties for the machines in the future.

2017-09-14xlnx-ep108: Rename to ZCU102Alistair Francis
The EP108 is a early access development board. Now that silicon is in production people have access to the ZCU102. Let's rename the internal QEMU files and variables to use the ZCU102. There is no functional change here as the EP108 is still a valid board option. Signed-off-by: Alistair Francis <alistair.francis@xilinx.com> Reviewed-by: Edgar E.

2017-09-14target/arm: Rename 'type' to 'excret' in do_v7m_exception_exit()Peter Maydell
In the v7M and v8M ARM ARM, the magic exception return values are referred to as EXC_RETURN values, and in QEMU we use V7M_EXCRET_* constants to define bits within them. Rename the 'type' variable which holds the exception return value in do_v7m_exception_exit() to excret, making it clearer that it does hold an EXC_RETURN value.

2017-09-14target/arm: Add and use defines for EXCRET constantsPeter Maydell
The exception-return magic values get some new bits in v8M, which makes some bit definitions for them worthwhile. We don't use the bit definitions for the switch on the low bits which checks the return type for v7M, because this is defined in the v7M ARM ARM as a set of valid values rather than via per-bit checks.

2017-09-14target/arm: Remove unnecessary '| 0xf0000000' from do_v7m_exception_exit()Peter Maydell
In do_v7m_exception_exit(), there's no need to force the high 4 bits of 'type' to 1 when calling v7m_exception_taken(), because we know that they're always 1 or we could not have got to this "handle return to magic exception return address" code.

2017-09-14nvic: Don't apply group priority mask to negative prioritiesPeter Maydell
In several places we were unconditionally applying the nvic_gprio_mask() to a priority value. This is incorrect if the priority is one of the fixed negative priority values (for NMI and HardFault), so don't do it. This bug would have caused both NMI and HardFault to be considered as the same priority and so NMI wouldn't correctly preempt HardFault.

2017-09-08pci: add reserved slot check to do_pci_register_device()Mark Cave-Ayland
Add a new slot_reserved_mask bitmask to PCIBus indicating whether or not each PCI slot on the bus is reserved. Ensure that it is initialised to zero to maintain the existing behaviour that all slots are available by default, and add the additional check with appropriate error reporting to do_pci_register_device().

2017-09-08vmgenid: replace x-write-pointer-available hackMarc-André Lureau
This compat property sole function is to prevent the device from being instantiated. Instead of requiring an extra compat property, check if fw_cfg has DMA enabled. fw_cfg is a built-in device that is initialized very early by the machine init code. We have at least one other device that also assumes fw_cfg_find() can be safely used on realize: pvpanic. This has the additional benefit of handling other cases properly, like: $ qemu-system-x86_64 -device vmgenid -machine none qemu-system-x86_64: -device vmgenid: vmgenid requires DMA write support in fw_cfg, which this machine type does not provide $ qemu-system-x86_64 -device vmgenid -machine pc-i440fx-2.9 -global fw_cfg.dma_enabled=off qemu-system-x86_64: -device vmgenid: vmgenid requires DMA write support in fw_cfg, which this machine type does not provide $ qemu-system-x86_64 -device vmgenid -machine pc-i440fx-2.6 -global fw_cfg.dma_enabled=on [boots normally] Suggested-by: Eduardo Habkost <ehabkost@redhat.com> Signed-off-by: Marc-André Lureau <marcandre.lureau@redhat.com> Reviewed-by: Michael S.

2017-09-08hw/pci: add QEMU-specific PCI capability to the Generic PCI Express Root PortAleksandr Bezzubikov
To enable hotplugging of a newly created pcie-pci-bridge, we need to tell firmware (e.g. SeaBIOS) to reserve additional buses or IO/MEM/PREF space for pcie-root-port. Additional bus reservation allows us to hotplug pcie-pci-bridge into this root port. The number of buses and IO/MEM/PREF space to reserve are provided to the device via a corresponding property, and to the firmware via new PCI capability. The properties' default values are -1 to keep default behavior unchanged.

This reverts commit 153eba4726dfa1bdfc31d1fe973b2a61b9035492. This patch prevents PCI passthrough hotplug on Xen. Even if the Xen tool stack prepares its own ACPI tables, we still rely on QEMU for hotplug ACPI notifications.
