            Bug ID: 750319
           Summary: memory: subclasses don't know map flags in unmap
    Classification: Platform
           Product: GStreamer
           Version: git master
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: Normal
         Component: gstreamer (core)
          Assignee: gstreamer-bugs at lists.freedesktop.org

     GNOME version: ---

There are gstmemory's available that operate in two memory domains and need to
ensure consistent access between these domains.

Imagine a scenario where e.g. the GLMemory is mapped twice in both the GPU and
the CPU domain.  On unmap or a subsequent map, it would like to ensure that the
most recent data is available in the memory domain requested.  Either by
flushing the writes and/or initiating a DMA transfer.  Without knowing which
domain is being unmapped, the memory does not know where the most recent data
is to transfer to the other memory domain.
