DMB vs DSB in ARM

[Zhang Zeren]

Hi all,

As far as I understand it , they both provide a full memory barrier, but
their usage in the real world is still vague to me. I noticed that a lot of
DSBs is used while flushing the TLB, can these DSBs be replaced by DMB? Why?

Thanks in advance,
Zhang Zeren
