Did yo ever get a reply to this? That sounds like just what I want to do (well, it sounds just like what our vxworks code does to do what I want to do, which I guess is good enough). TIA, --Gus On Tue, 26 Jun 2001 jtm@smoothsmoothie.com wrote:
I am looking for a solution to a similar problem. I am writing a driver for an FCC on the 8260 in transparent mode, and need to allocate buffer memory. The buffer memory will get filled via DMA, and therefore must not be cached. Will the following work correctly? vaddr = kmalloc(BUF_SIZE, GFP_DMA); paddr = __pa(vaddr); Thanks. -- Jay Monkman The truth knocks on the door and you say "Go away, I'm monkman@jump.net looking for the truth," and so it goes away.
