Migration is specific to system emulation. - Move the CPUClass::vmsd field to SysemuCPUOps, - restrict VMSTATE_CPU() macro to sysemu, - vmstate_dummy is now unused, remove it. Signed-off-by: Philippe Mathieu-Daudé <f4bug@amsat.org> --- Since v3: Merged in patch 1 (Eduardo) therefore removed Richard R-b. 'vmsd' is not a 'system operation' prototype but a const pointer field, so it belongs to a const structure, but maybe this structure could be better named than SysemuCPUOps? This field comes from: commit b170fce3dd06372f7bfec9a780ebcb1fce6d57e4 Author: Andreas Färber <afaerber@suse.de> Date: Sun Jan 20 20:23:22 2013 +0100 cpu: Register VMStateDescription through CPUState In comparison to DeviceClass::vmsd, CPU VMState is split in two, "cpu_common" and "cpu", and uses cpu_index as instance_id instead of -1. Therefore add a CPU-specific CPUClass::vmsd field. Unlike the legacy CPUArchState registration, rather register CPUState. --- include/hw/core/cpu.h | 7 ++----- include/hw/core/sysemu-cpu-ops.h | 4 ++++ include/migration/vmstate.h | 2 -- cpu.c | 18 ++++++++---------- stubs/vmstate.c | 2 -- target/alpha/cpu.c | 3 ++- target/arm/cpu.c | 2 +- target/avr/cpu.c | 2 +- target/cris/cpu.c | 3 ++- target/hppa/cpu.c | 3 ++- target/i386/cpu.c | 2 +- target/lm32/cpu.c | 2 +- target/m68k/cpu.c | 3 ++- target/microblaze/cpu.c | 3 ++- target/mips/cpu.c | 2 +- target/moxie/cpu.c | 2 +- target/nios2/cpu.c | 7 +++++++ target/openrisc/cpu.c | 3 ++- target/riscv/cpu.c | 4 ++-- target/rx/cpu.c | 6 ++++++ target/s390x/cpu.c | 2 +- target/sh4/cpu.c | 5 +++-- target/sparc/cpu.c | 2 +- target/tricore/cpu.c | 7 +++++++ target/unicore32/cpu.c | 3 ++- target/xtensa/cpu.c | 5 +++-- target/ppc/translate_init.c.inc | 2 +- 27 files changed, 65 insertions(+), 41 deletions(-)
