pseries: Rework irq assignment to avoid carrying qemu_irqs around
Currently, the interfaces in the pseries machine code for assignmentand setup of interrupts pass around qemu_irq objects. That was donein an attempt not to be too closely linked to the specific XICS...
pseries: added allocator for a block of IRQs
The patch adds a simple helper which allocates a consecutive sequenceof IRQs calling spapr_allocate_irq for each and checks that allocatedIRQs go consequently.
The patch is required for upcoming support of MSI/MSIX on POWER....
pseries dma: DMA window params added to PHB and DT population changed
Previously the only PCI bus supported was the emulated PCI bus withfixed DMA window with start at 0 and size 1GB. As we are going to supportPCI pass through which DMA window properties are set by the host...
PPC: spapr: Remove global variable
Global variables are bad. Let's move spapr_has_graphics into themachine state struct.

pseries: Implement IOMMU and DMA for PAPR PCI devices
Currently the pseries machine emulation does not support DMA for emulatedPCI devices, because the PAPR spec always requires a (guest visible,paravirtualized) IOMMU which was not implemented. Now that we have...
pseries: Convert sPAPR TCEs to use generic IOMMU infrastructure
The pseries platform already contains an IOMMU implementation, since it isessential for the platform's paravirtualized VIO devices. This IOMMUsupport is currently built into the implementation of the VIO "bus" and...
spapr: Add "memop" hypercall
This adds a qemu-specific hypervisor call to the pseries machinewhich allows to do what amounts to memmove, memcpy and xor overregions of physical memory such as the framebuffer.
This is the simplest way to get usable framebuffer speed from...
pseries: Clean up hcall_dprintf() debugging messages
The pseries machine code has a number of debug messages for debugging PAPRhypercalls, dependent on DEBUG_SPAPR_HCALLS. This patch cleans thesemessages up a bit, by adding func to the hcall_dprintf() macro and...
pseries: Add support for level interrupts to XICS
The pseries "xics" interrupt controller, like most interruptcontrollers can support both message (i.e. edge sensitive) interruptsand level sensitive interrupts, but it needs to know which are which.
When I implemented the xics emulation for qemu, the only devices we...

pseries: FDT NUMA extensions to support multi-node guests
Add NUMA specific properties to guest's device tree to boot a multi-nodeguests. This patch adds the following properties:

fix spelling in hw sub directory
Correct obvious spelling errors in qemu/hw directory.

pseries: Add partial support for PCI
This patch adds a PCI bus to the pseries machine. This instantiatesthe qemu generic PCI bus code, advertises a PCI host bridge in theguest's device tree and implements the RTAS methods specified by PAPRto access PCI config space. It also sets up the memory regions we...
pseries: Refactor spapr irq allocation
Paulo Bonzini changed the original spapr code, which manually assigned irqnumbers for each virtual device, to allocate them automatically from thedevice initialization. That allowed spapr virtual devices to be constructed...
pseries: Implement set-time-of-day RTAS function
Currently there is no implementation for set-time-of-day rtas function,which causes the following warning "setting the clock failed (-1)" onthe guest.
This patch just creates this function, get the timedate diff and store in...
pseries: More complete WIMG validation in H_ENTER code
Currently our implementation of the H_ENTER hypercall, which inserts amapping in the hash page table assumes that only ordinary memory is evermapped, and only permits mapping attribute bits accordingly (WIMG==0010)....
spapr: proper qdevification
Right now the spapr devices cannot be instantiated with -device,because the IRQs need to be passed to the spapr_*_create functions.Do this instead in the bus's init wrapper.
This is particularly important with the conversion from scsi-disk...

Delay creation of pseries device tree until reset
At present, the 'pseries' machine creates a flattened device tree in themachine->init function to pass to either the guest kernel or to firmware.
However, the machine->init function runs before processing of -device...
Implement hcall based RTAS for pSeries machines
On pSeries machines, operating systems can instantiate "RTAS" (Run-TimeAbstraction Services), a runtime component of the firmware which implementsa number of low-level, infrequently used operations. On logical partitions...
Implement the PAPR (pSeries) virtualized interrupt controller (xics)
PAPR defines an interrupt control architecture which is logically dividedinto ICS (Interrupt Control Presentation, each unit is responsible forpresenting interrupts to a particular "interrupt server", i.e. CPU) and...
Start implementing pSeries logical partition machine
This patch adds a "pseries" machine to qemu. This aims to emulate alogical partition on an IBM pSeries machine, compliant to the"PowerPC Architecture Platform Requirements" (PAPR) document.
This initial version is quite limited, it implements a basic machine...
Implement the bus structure for PAPR virtual IO
This extends the "pseries" (PAPR) machine to include a virtual IO bussupporting the PAPR defined hypercall based virtual IO mechanisms.
So far only one VIO device is provided, the vty / vterm, providinga full console (polled only, for now)....
