DMB vs DSB in ARM

[Zhang Zeren <zhangzr23@xxxxxxxxx>]

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
