This doc patch provides an initial description of the hcall op-codes that are used by Linux kernel running as a guest (LPAR) on top of PowerVM or any other sPAPR compliant hyper-visor (e.g qemu). Apart from documenting the hcalls the doc-patch also provides a rudimentary overview of how hcall ABI, how they are issued with the Linux kernel and how information/control flows between the guest and hypervisor.
