[PATCH v2 0/2] pci: add romsize property

Posted by Paolo Bonzini 4 years, 9 months ago

This property can be useful for distros to set up known-good ROM sizes for
migration purposes.  The VM will fail to start if the ROM is too large,
and migration compatibility will not be broken if the ROM is too small.

The main difference from v1 is the first patch, which fixes overflow
issues in nearby code.  The second patch is the same as v1 except for
replacing %d->%u in the error message.
