2021-05-26cpu: Move CPUClass::vmsd to SysemuCPUOpsPhilippe Mathieu-Daudé1-2/+0
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.

2020-01-20migration: Change SaveStateEntry.instance_id into uint32_tPeter Xu1-1/+1
It was always used as 32bit, so define it as used to be clear. Instead of using -1 as the auto-gen magic value, we switch to UINT32_MAX. We also make sure that we don't auto-gen this value to avoid overflowed instance IDs without being noticed.

2017-05-17migration: Move check_migratable() into qdev.cJuan Quintela1-3/+2
The function is only used once, and nothing else in migration knows about objects. Create the function vmstate_device_is_migratable() in savem.c that really do the bit that is related with migration. Signed-off-by: Juan Quintela <quintela@redhat.com> Reviewed-by: Peter Xu <peterx@redhat.com>
2017-02-28migrate: Introduce a 'dc->vmsd' check to avoid segfault for --only-migratableAshijeet Acharya1-0/+6
Commit a3a3d8c7 introduced a segfault bug while checking for 'dc->vmsd->unmigratable' which caused QEMU to crash when trying to add devices which do no set their 'dc->vmsd' yet while initialization. Place a 'dc->vmsd' check prior to it so that we do not segfault for such devices. NOTE: This doesn't compromise the functioning of --only-migratable option as all the unmigratable devices do set their 'dc->vmsd'. Introduce a new function check_migratable() and move the only_migratable check inside it, also use stubs to avoid user-mode qemu build failures.

2016-10-17tests: cleanup ptimer-testPaolo Bonzini1-5/+0
1) ptimer-test is not a qtest---it runs the ptimer.c code directly in the ptimer-test process 2) ptimer-test has its own stubs file, so there is no need to add more stubs to stubs/vmstate.c Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Reviewed-by: Dmitry Osipenko <digetx@gmail.com> Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
