[RFC PATCH v2 00/20] hw: Mark the device with no migratable fields |
Date: |
Sun, 17 Jan 2021 20:24:26 +0100 |
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
