请问OMAP-L138的ARM端Cache 的write back和write through机制问题

Other Parts Discussed in Thread: OMAP-L138

我想问一下,OMAP-L138 ARM端的cache是否支持write through功能?

这个功能一般是什么时候会用到?

我们这边测试cache性能的时候,不清楚arm端的cache一致性怎么测,担心arm端会出现cahce一致性问题,想把cahce配置成write through方式。

我看你们的SDK包上的linux kernel是不支持这个功能的,请问是为什么?器件支不支持这功能?

多谢。
