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...
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)....
Virtual hash page table handling on pSeries machine
On pSeries logical partitions, excepting the old POWER4-style full systempartitions, the guest does not have direct access to the hardware pagetable. Instead, the pagetable exists in hypervisor memory, and the guest...
