WebAs your client becomes more comfortable telling their story, you’ll begin to focus on the more uncomfortable parts of their experience. Ask your client to share their worst memory, or the worst moments, of their trauma. Dig … WebMany drivers need lots of small DMA-coherent memory regions for DMA descriptors or I/O buffers. Rather than allocating in units of a page or more using dma_alloc_coherent(), you can use DMA pools. These work much like a struct kmem_cache, except that they use the DMA-coherent allocator, not __get_free_pages().
WebDrivers and subsystems depend on it. If an architecture isn’t fully DMA-coherent (i.e. hardware doesn’t ensure that data in the CPU cache is identical to data in main memory), ARCH_DMA_MINALIGN must be set so that the memory allocator makes sure that kmalloc’ed buffer doesn’t share a cache line with the others.
