3.5.2.5.5. Configure the Device Communication
Configuration for PF-PF communication by using debugfs interface
Loopback ED has the provision to switch the packets from one channel to another channel.
cd /sys/kernel/debug/ifc_mcdma_config/
Configure from PF0 to PF1
echo src_chnl_no > src_chnl
echo dst_chnl_no > dst_chnl
echo 1 > update
Configure from PF1 to PF0
echo src_chnl_no > src_chnl
echo dst_chnl_no > dst_chnl
echo 1 > update
For example:
- Configure the communication from channel number 64 to channel number 0.
echo 64 > src_chnl echo 0 > dst_chnl echo 1 > update
- Configure the communication from channel number 0 to channel number 64.
echo 0 > src_chnl echo 64 > dst_chnl echo 1 > update
