Driver to enable Composable DMA Transfer(CDX) Bus. CDX bus
|
||
|
|
exposes Fabric devices which uses composable DMA IP to the
|
||
|
|
APU. CDX bus provides a mechanism for scanning and probing
|
||
|
|
of CDX devices. CDX devices are memory mapped on system bus
|
||
|
|
for embedded CPUs. CDX bus uses CDX controller and firmware
|
||
|
|
to scan these CDX devices.
