flush_kernel_dcache_page is a rather confusing interface that implements a subset of flush_dcache_page by not being able to properly handle page cache mapped pages. The only callers left are in the exec code as all other previous callers were incorrect as they could have dealt with page ...
问为什么flush_dcache_page()在linux内核中什么也不做?EN第一种方法纵向或者横向来读都可以,因为代码...
它其实就是到__proc_info_begin开始的section中去找到对应当前SOC中用的CPU Cache相关的operation list 再由arch/arm/kernel/vmlinux.lds.S可以__proc_info_begin就是section *(.proc.info.init)的开始地址。 __proc_info_begin = .; *(.proc.info.init) __proc_info_end = .; 而我们知道我们所用是AR...
所以其实flush_cache_all 在我们的项目中就是arm926_flush_kern_cache_all:其实现在同一个文件中: /* * flush_kern_cache_all() * Clean and invalidate the entire cache. */ ENTRY(arm926_flush_kern_cache_all) mov r2, #VM_EXEC mov ip, #0 __flush_whole_cache: #ifdef CONFIG_CPU_DCACHE_WRITE...

The old data cache flush function, FlushDCache, is deprecated and should never be used. OEMCacheRangeFlush is called in the following cases: CacheSync is called. This is a public API that anyone can call. When the kernel loads DLLs or executable files. Whenever the kernel debugger is activ...
To flush and invalidate the instruction cache, use the OEMCacheRangeFlush function instead. This function is used to flush and invalidate the instruction cache. It is called by the kernel. The kernel flushes and invalidates the instruction cache when a process loads, a process switch occurs, ...
Page 6 of your PDF is very helpful but I am still confused with one aspect. 1. ARM -> PL, I got the order as follows (clean L1 first and then L2): cpu_cache.flush_kern_dcache_area(virt_addr, size); // same as macro __cpuc_flush_dcache_area outer_cache.inv_range(phy_addr...
