Can we do malloc in kernel instead of kmalloc? the malloc() can be called in user-space and kernel-space, and it allocates a physically fragmented memory area. but kmalloc() can be called only in kernel-space, and it allocates physically contiguous memory chunk.
Can you use malloc in kernel? None whatsoever. This means that ANY function you’re calling in the kernel needs to be defined in the kernel. Linux does not define a malloc, hence you can’t use it. There is a memory allocator and a family of memory allocation functions.
When should I use Kmalloc? kmalloc is the preferred way, as long as you don’t need very big areas. The trouble is, if you want to do DMA from/to some hardware device, you’ll need to use kmalloc, and you’ll probably need bigger chunk. The solution is to allocate memory as soon as possible, before memory gets fragmented.
