WebWe would like to show you a description here but the site won’t allow us. WebChapterÂ 8.Â Allocating Memory. Thus far, we have used kmalloc and kfree for the allocation and freeing of memory. The Linux kernel offers a richer set of memory allocation primitives, however. In this chapter, we look at other ways of using memory in device drivers and how to optimize your systemâ s memory resources.

WebIn my understanding, kmalloc () returns memory with DMA safe alignment in order to avoid cache-sharing problem when used for DMA. The alignment is decided by ARCH_DMA_MINALIGN. For example, on modern ARM 32bit boards, this value is typically 64. So, memory returned by kmalloc () has at least 64 byte alignment. WebIt will try to allocate memory with kmalloc and if the allocation fails it will be retried with vmalloc. There are restrictions on which GFP flags can be used with kvmalloc; please see kvmalloc_node () reference documentation. Note that kvmalloc may return memory that is not physically contiguous.
