Since v1: - Tried to address Dave and Daniel comments - Added Peter R-b - Handle GPEX device
This is a proof-of-concept after chatting with Peter Maydell on IRC last year. Introduce the vmstate_no_state_to_migrate structure, and a reference to it: vmstate_qdev_no_state_to_migrate. Use this reference in devices with no fields to migrate. This is useful to catch devices missing vmstate, such: - ads7846 - mcf-uart - mcf-fec - versatile_i2c - ... v1: https://www.mail-archive.com/qemu-devel@nongnu.org/msg719788.html Philippe Mathieu-Daudé (20): migration/vmstate: Restrict vmstate_dummy to user-mode hw/core/qdev: Add vmstate_qdev_no_state_to_migrate hw/arm/armv7m: Mark the device with no migratable fields hw/arm/aspeed_soc: Mark the device with no migratable fields hw/arm/bcm283x: Mark devices with no migratable fields hw/arm/msf2-soc: Mark the device with no migratable fields hw/core/split-irq: Mark the device with no migratable fields hw/cpu/a9mpcore: Mark the device with no migratable fields hw/cpu/cluster: Mark the device with no migratable fields hw/usb/hcd-ohci: Mark the device with no migratable fields hw/intc/arm_gicv2m: Mark the device with no migratable fields hw/misc/armsse-cpuid: Mark the device with no migratable fields hw/misc/iotkit-sysinfo: Mark the device with no migratable fields hw/misc/unimp: Mark the device with no migratable fields hw/nubus/mac-nubus-bridge: Mark the device with no migratable fields hw/sparc64/sun4u: Mark devices with no migratable fields hw/pci-host/gpex: Mark device with no migratable fields hw/core/qdev: Display warning for devices missing migration state stubs/vmstate: Add VMSTATE_END_OF_LIST to vmstate_user_mode_cpu_dummy migration/vmstate: Simplify vmstate for user-mode CPU configure | 10 ++++++++++ meson.build | 1 + hw/usb/hcd-ohci.h | 2 ++ include/hw/arm/bcm2836.h | 5 +++-- include/hw/arm/msf2-soc.h | 11 ++++++----- include/hw/core/cpu.h | 2 +- include/hw/cpu/a9mpcore.h | 3 ++- include/hw/qdev-core.h | 2 ++ include/migration/vmstate.h | 2 +- hw/arm/armv7m.c | 1 + hw/arm/aspeed_soc.c | 1 + hw/arm/bcm2835_peripherals.c | 1 + hw/arm/bcm2836.c | 1 + hw/arm/msf2-soc.c | 1 + hw/core/qdev.c | 8 ++++++++ hw/core/split-irq.c | 1 + hw/cpu/a9mpcore.c | 1 + hw/cpu/cluster.c | 1 + hw/intc/arm_gicv2m.c | 2 ++ hw/misc/armsse-cpuid.c | 1 + hw/misc/iotkit-sysinfo.c | 1 + hw/misc/unimp.c | 1 + hw/nubus/mac-nubus-bridge.c | 1 + hw/pci-host/gpex.c | 1 + hw/sparc64/sun4u.c | 6 +++++- hw/usb/hcd-ohci.c | 1 + migration/vmstate.c | 7 +++++++ stubs/vmstate.c | 7 ++++++- 28 files changed, 70 insertions(+), 12 deletions(-) -- 2.26.2
