DMA for Ethernet Controller (Announce)

posted by martin.joni, 17.04.2016, 16:14

Hello,

I'm actually struggling to set up DMA under current hardware.
I've a SOM 7567 Board which is X86 compatible.
I'm Programming Win32 using DPMI 0.9
I currently get it managed to Map BARs and I'm able to configure registers.

My problem is to get physical adressable memory which is DMA capable. As far as i know is need to get memory above 16MB due to Processos restriction (intel e3800).
But I failed to setup XMS oder VDS.

I'd appreciate if someone has new ideas or is familiar with this issue.

Best Regards
Jonathan
