[Qemu-devel] [PATCH v7 0/4] ramblock: add hmp command "info ramblock"

[Peter Xu]

v7:
- patch 1: removed Dave's r-b since the patch conflicted during rebase
- patch 2: add r-b for Markus, with the nice function comment that
  provided [Markus]
- patch 3: add r-b for Dave
- patch 4 (new): added new patch to remove assert in size_to_str(),
  assuming that would be better.

v6
- patch 2: instead of create a new size_to_str(), abstract the logic
  out from print_type_size(), refactor it, to make sure
  print_type_size() dumps exactly the same thing as before. (a simple
  test with info qtree is done)
- let suffixes be an array of strings [Markus]

v5
- add r-b for Dave on first patch (which I forgot in v4, so I got it
  again)
- add one more patch to introduce size_to_str() as patch 2 [Dave]
- let the last patch use the new interface

v4:
- move page_size_to_str() into util/cutil.c [Dave]

v3:
- cast the three PRIx64 addresses using (uint64_t) [Fam]
- add more comment in patch 2 to emphasize that this command is only
  suitable for HMP, not QMP [Markus]

v2:
- replace "lx" with "PRIx64" in three places

Sometimes I would like to know ramblock info for a VM. This command
would help. It provides a way to dump ramblock info. Currently the
list is by default sorted by size, though I think it's good enough.

Please review, thanks.

  ramblock: add RAMBLOCK_FOREACH()
  utils: provide size_to_str()
  ramblock: add new hmp command "info ramblock"
