From 0efa66da9c8638270ac03a02d184473b7a049fe8 Mon Sep 17 00:00:00 2001 From: David Gibson Date: Thu, 27 Apr 2017 02:15:54 +0200 Subject: [PATCH 19/23] target/ppc: Add new H-CALL shells for in memory table translation RH-Author: David Gibson Message-id: <20170427021558.4884-4-dgibson@redhat.com> Patchwork-id: 74914 O-Subject: [Pegas-1.0 qemu-kvm-rhev PATCH 3/7] target/ppc: Add new H-CALL shells for in memory table translation Bugzilla: 1368786 RH-Acked-by: Thomas Huth RH-Acked-by: Laurent Vivier RH-Acked-by: Miroslav Rezanina From: Suraj Jitindar Singh The use of the new in memory tables introduced in ISAv3.00 for translation, also referred to as process tables, requires the introduction of 3 new H-CALLs; H_REGISTER_PROCESS_TABLE, H_CLEAN_SLB, and H_INVALIDATE_PID. Add shells for each of these and register them as the hypercall handlers. Currently they all log an unimplemented hypercall and return H_FUNCTION.
