Re: Kmalloc returns which address

hi Scott

yes really it would really generate a machine check... but i guess if you
convert this virt address to physical address using __pa() then pass it to
the ioremap() i guess things will work .

Please correct me if i am wrong

I want know the address return by kmalloc function? is it physical

Kernel virtual.

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?

You need to convert it; read Documentation/DMA-mapping.txt.
