[Qemu-devel] [PATCH 0/5] hw/block/pflash: Add DeviceReset() handlers

Posted by Philippe Mathieu-Daudé 4 years, 11 months ago

The pflash device lacks a reset() function.
When a machine is resetted, the flash might be in an
inconsistent state, leading to unexpected behavior:
https://bugzilla.redhat.com/show_bug.cgi?id=1678713

Resolve this issue by adding a DeviceReset() handler.

Both CFI01/CFI02 devices are fixed by this series.

Regards,

Phil.
