accesses to the appropriate subset of the last-level caches when, for example, some of the last-level caches are 'off.' The chip controls the power consumption by turning on and off cache slices based on power states, and consequently dynamically switches among at least two hash functions.Patrick P.

你就得在CPU端读取之前,调用invalidate cache操作;在CPU写入数据后,进行flush cache操作(CPU的Cache到主存RAM都会有一些延迟)。Map/UnMap并不会自动的执行相关操作。所以Vulkan提供了vkFlushMappedMemoryRanges(),vkInvalidateMappedMemoryRanges()作为CPU写入/CPU读取相关的刷新函数。VMA提供了更为方便的接口vmaFlushAllocati...
In this technique, a number of mapping functions are used to transfer the data from main memory to cache memory. That means any main memory can be mapped into any cache line. Therefore, cache memory address is not in the use. Associative cache controller interprets the request by using the...
In Direct mapped cache memory, each block mapped to exactly one location in cache memory. A particular block of main memory can map the line number of cache is given by - Cache line number = (Block Address of Main Memory) modulo (Number of lines in Cache). ...
speed up the access to the flash memory and, on the other hand, that most flash memory caches achieve flushing (eviction) involving groups of pages in order to minimize the merge operation between valid data in cache and valid data in flash memory for a given block (see further section ...
SEC_NOCACHE 0x10000000 Sets all pages to noncachable. Applications should not use this flag except when explicitly required for a device. Using the interlocked functions with memory mapped with SEC_NOCACHE can result in an EXCEPTION_ILLEGAL_INSTRUCTION exception. SEC_NOCACHE requires either S...
Address types used in Linux If you have a logical address, the macro _ _pa( ) (defined in <asm/page.h>) returns its associated physical address. Physical addresses can be mapped back to logical addresses with _ _va( ), but only for low-memory pages. Different kernel functions require ...
