[Gc-linux-devel] Re: Re: dvd kernelmodule: memory address problem

[JockyW <joc...@ho...>]

Problem finally solved by allocating buffer memory with kmalloc
Like this: kmalloc (BUF_DISC, GFP_DMA);
The flag indicates that the allocated memory can be used in DMA transfers.
My original method, allocating a static char array, definitely doesn't work.
The virtual address 0xC200EB40 is not associated or cannot be mapped to
physical memory.

I still have no idea with what other memory it is associated. So if someone
can clear me up I would feel even more relieved.
