PCI DMA address

Hello all, How can kernel get the PCI DMA address above 16MB or 64MB? I hope that the all PCI devices can use a dma address above 0x100 at a higher memory. Thanks. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message

[PATCH] maestro3 2.4.2 pci dma address fix

It seems the maestro3 can't DMA from mem above 256M. Thanks to everyone who sent in bug reports that lead us to discover this.. this patch fixes that and also allocates memory at driver init time rather than at device open time.. please apply with wild abandon. -- zach --- linux-2.4.2/dri
