Hi all,
I found that the header file(dma-mapping.h) has changed. I saw this
change has happened on Linux -2.6.28 kernel onwards. earlier kernel is having
COMFIT_PPC64 macro. Based on this macro the things were happened. Is there any
fixes available right now or any reasons behind this changes.
Regards,
T.

Subject: Regarding TSI108 ethernet DMA issue
Hi all,
I am trying to port linux 2.6.30 for my TSI108 based custom board where
i am getting the following kernel panic message. I found that it was due to dma
allocation function call particularly dma_alloc_coherent() of tsi108_open
function. When we see the implementation of dma_alloc_coherent. It was bit
changed from the previous linux versions it seems.
The implementation of dma_alloc_coherent was kept on the
arch/powerpc/include/asm/dma-mapping.h file. Earlier implementation is not
considering the first parameter what the tsi108 driver is passing as NULL. But
the current implementation is considering this parameter and because of this
the panic is coming what i believe.
So kindly let me know any patches for this problem or any fixes.
Regards,
T.
