Implement PAPR VPA functions for pSeries shared processor partitions

Shared-processor partitions are those where a CPU is time-sliced between
partitions, rather than being permanently dedicated to a single
partition. qemu emulated partitions, since they are just scheduled with...

Implement hcall based RTAS for pSeries machines

On pSeries machines, operating systems can instantiate "RTAS" (Run-Time
Abstraction Services), a runtime component of the firmware which implements
a number of low-level, infrequently used operations. On logical partitions...

Implement assorted pSeries hcalls and RTAS methods

This patch adds several small utility hypercalls and RTAS methods to
the pSeries platform emulation. Specifically:

  • 'display-character' rtas call

This just prints a character to the console, it's occasionally used...

Start implementing pSeries logical partition machine

This patch adds a "pseries" machine to qemu. This aims to emulate a
logical 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...

Virtual hash page table handling on pSeries machine

On pSeries logical partitions, excepting the old POWER4-style full system
partitions, the guest does not have direct access to the hardware page
table. Instead, the pagetable exists in hypervisor memory, and the guest...
