Hi,
I would like a clarification for dma.
The context: most dma capable devices have 32 bits address range.
Is it correct that, if there was no 3G/1G mapping in the kernel, or that kernel low memory could map 4Gb memory, one could choose any free addresses in that low memory to set up a dma buffer?
That would avoid all the mapping hassle, and performance cost associated.
Thanks
