Hi,
I'm looking to utilize the DM6467 as a PCI master and am wondering how well supported this functionality is in Linux. Are there suitable drivers that would allow us to interface to existing PCI modules? Has anybody played with this functionality at all? I understand there are some hardware issues at the silicon level... has that been worked around? We were originally using a DM6446 for our application, but it needs DMA to a hard drive and some external interface to DM642s and an FPGA. We were going to use VLYNQ to communicate with the other silicon (and dodge the EMIF/DMA ATA issue), but would rather slap everything on a PCI bus (upgrading the 642s to 648s). We still need the DMA hard drive functionality, though, and seeing as how the pins for PCI and ATA are also multiplexed, we're not sure that we're gaining much going to PCI. Although, if I'm not mistaken, the pin multiplexing problem with ATA DMA can be alleviated with some driver patches... any ground gained there? Thanks; any insight appreciated!
