Line17#defineflush_dcache_page(page) do {} while (0) Run Code Online (Sandbox Code Playgroud) 我认为 x86 arch 上有缓存刷新指令“CLFLUSH”,它可以用于此页面刷新。 然而,flush_dcache_page() 并不像上面的源代码那样运行任何 CPU 指令。

To flush and invalidate the data cache, use the OEMCacheRangeFlush function instead.This function is called by the kernel to flush and invalidate the data cache. The data cache is flushed/invalidated when CacheSync is called.Copy void FlushDCache(void); ...
xil_dcacheflush函数是用于特定缓存操作的重要函数。 该函数在相关系统中对数据一致性维护有重要作用。它能确保数据在缓存与主存间的正确同步。调用此函数可防止数据在缓存中出现不一致情况。当数据更新后常需使用xil_dcacheflush函数。它的执行能保障后续读取到最新的数据。多线程环境下xil_dcacheflush函数作用关键。此...
