Hello, I'm completely new and stupid in embedded Linux for PowerPC. My
embedded PowerPC has 32-byte cache line size. Therefore I would like to
get always chunks of the memory which are aligned to 32 bytes boundary.
But running simple test I see that's always aligned to 8 bytes boundary
- malloc(). Does anybody know how kmalloc works? How alignment in this
case works? Is there some way how to enforce such aligment? I saw that
QNX works the same way. Thanks.
