Subject: kmalloc with GFP_DMA, or get_free_pages!!!
Date: Tue, 20 Mar 2001 14:11:50 -0500	[thread overview]
Message-ID: <85256A15.00692E23.00@alpha2.storage.com> (raw)

To allocate memory for DMA operations, i can use kmalloc (,,GFP_DMA.. ). In
which case I need to use get_free_pages? Both the above gives me the
contiguous memory. I understand that get_free_pages gives me in terms of
pages. So it would be more than the memory which i asked for. I am not sure
watz the exact difference between these two.

Could anyone plz lemme know about this?

Thanks
Jalaja
