[Qemu-devel] [PATCH 0/3] memory-device: refine memory_device_get_free_addr

Posted by Wei Yang 4 years, 9 months ago

When we iterate the memory-device list to get the available range, it is not
necessary to iterate the whole list.

1) the first non-overlap range is the proper one if no hint is provided
2) no more overlap for hinted range if tmp exceed it

Wei Yang (3):
  memory-device: not necessary to use goto for the last check
  memory-device: break the loop if no hint is provided
  memory-device: break the loop if tmp exceed the hinted range
