[edk2-devel] [PATCH 1/1] OvmfPkg/IoMmuDxe: add locking to IoMmuAllocateCommonBuffer

[Gerd Hoffmann]

  Hi,

Not a straight forward conversion, current code copies around bitmap
snippets, so this logic needs a rewrite to work with
InterlockedCompareExchange32().  Don't have the time to do that now
(leaving tomorrow for my three week summer vacation ...).

take care,
  Gerd
