Hi,
Does Armv7-A have a write buffer?
If yes, when will the write buffer be drained and what's the purpose of write buffer?
OK.
Thank you very much.
I have another question. DMB is enough to drain store buffer, am I right?
DMB ensures ordering only.
It will not "wait" for the write buffer.

Thank you!
