Provide initial documentation for PAPR hcalls # # 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. # # Signed-off-by: Vaibhav Jain # Reviewed-by: Laurent Dufour # Acked-by: Nicholas Piggin # [mpe: Add SPDX tag, add it to
