qemu_system_reset() function always performs the same basic actions on all machines. This includes running all the reset handler hooks, however the order in which these will run is not always easily predictable. This patch splits the core of qemu_system_reset() - the invocation of the reset handlers - out into a new qemu_devices_reset() function. qemu_system_reset() will usually call qemu_devices_reset(), but that can be now overriden by a new reset method in the QEMUMachine structure. Individual machines can use this reset method, if necessary, to perform any extra, machine specific initializations which have to occur before or after the bulk of the reset handlers. It's expected that the method will call qemu_devices_reset() at some point, but if the machine has really strange ordering requirements between devices resets it could even override that with it's own reset sequence (with great care, obviously). For a specific example of when this might be needed: a number of machines (but not PC) load images specified with -kernel or -initrd directly into the machine RAM before booting the guest. This mostly works at the moment, but to make this actually safe requires that this load occurs after peripheral devices are reset - otherwise they could have active DMAs in progress which would clobber the in memory images. Some machines (notably pseries) also have other entry conditions which need to be set up as the last thing before executing in guest space - some of this could be considered "emulated firmware" in the sense that the actions of the firmware are emulated directly by qemu rather than by executing a firmware image within the guest. When the platform's firmware to OS interface is sufficiently well specified, this saves time both in implementing the "firmware" and executing it. aliguori: don't unconditionally dereference current_machine Reviewed-by: NAndreas Färber <afaerber@suse.de> Signed-off-by: NDavid Gibson <david@gibson.dropbear.id.au> Signed-off-by: NAnthony Liguori <aliguori@us.ibm.com>

The pseries machine already supports the -vga std option, creating a graphics adapter. However, this is not very useful without being able to add a keyboard and mouse as well. This patch addresses this by adding a USB interface when requested, and automatically adding a USB keyboard and mouse when VGA is enabled. This is a stop gap measure to get usable graphics mode on pseries while waiting for Li Zhang's rework of USB options to go in after 1.2.

MacOSX 10.8 ("Mountain Lion") requires us to compile our one Objective-C source file with clang even if the rest of QEMU requires a real gcc, because the system headers we use make use of Apple's "Blocks" extension to C/ObjC, and mainline gcc doesn't support that. Since we only need to use a true gcc for the parts of QEMU that use the fixed-register env variable, we can simply use clang to build the ObjC file: it will link to the gcc-built objects with no problems. Add the necessary support for an OBJCC variable in the makefile and configure machinery; we default to clang if we have it, otherwise whatever CC is (since gcc might be the Apple gcc which does support Blocks).

Currently, when parsing a stream of tokens we make a copy of the token list at the beginning of each level of recursion so that we do not modify the original list in cases where we need to fall back to an earlier state. In the worst case, we will only read 1 or 2 tokens off the list before recursing again, which means an upper bound of roughly N^2 token allocations. For a "reasonably" sized QMP request (in this a QMP representation of cirrus_vga's device state, generated via QIDL, being passed in via qom-set), this caused my 16GB's of memory to be exhausted before any noticeable progress was made by the parser. This patch works around the issue by using single copy of the token list in the form of an indexable array so that we can save/restore state by manipulating indices. A subsequent commit adds a "large_dict" test case which exhibits the same behavior as above. With this patch applied the test case successfully completes in under a second.

Previously the only PCI bus supported was the emulated PCI bus with fixed DMA window with start at 0 and size 1GB. As we are going to support PCI pass through which DMA window properties are set by the host kernel, we have to support DMA windows with parameters other than default. This patch adds: 1. DMA window properties to sPAPRPHBState: LIOBN (bus id), start, size of the window. 2. An additional function spapr_dma_dt() to populate DMA window properties in the device tree which simply accepts all the parameters and does not try to guess what kind of IOMMU is given to it. The original spapr_dma_dt() is renamed to spapr_tcet_dma_dt().

Currently the RTAS functions for handling PCI are registered from the class init code for the PCI host bridge. That sort of makes sense now, but will break in the future when vfio gives us multiple types of host bridge for pseries (emulated and pass-through, at least). The RTAS functions will be common across all host bridge types (and will call out to different places internally depending on the type). So, this patch moves the RTAS registration into its own function called direct from the machine setup code.

Currently, the interfaces in the pseries machine code for assignment and setup of interrupts pass around qemu_irq objects. That was done in an attempt not to be too closely linked to the specific XICS interrupt controller. However interactions with the device tree setup made that attempt rather futile, and XICS is part of the PAPR spec anyway, so this really just meant we had to carry both the qemu_irq pointers and the XICS irq numbers around. This mess will just get worse when we add upcoming PCI MSI support, since that will require tracking a bunch more interrupt. Therefore, this patch reworks the spapr code to just use XICS irq numbers (roughly equivalent to GSIs on x86) and only retrieve the qemu_irq pointers from the XICS code when we need them (a trivial lookup). This is a reworked and generalized version of an earlier spapr_pci specific patch from Alexey Kardashevskiy.
