Hi, I am porting MPC8280 driver from vxWorks to Linux.
I want know the address return by kmalloc function? is it physical address or kernel virtual address. For Tx and Rx, hardware uses buffers, so I have to allocate buffers and pass the pointer to hardware. Can I pass the pointer returned kmalloc? or I should convert it into physical address? If it returns kernel virtual address, then how to convert into physical? Thanks & Regards- Suresh
