Hi All, I am trying to attach an ethernet device to ARM SMMU and use it in the dist setup where two ARM systems are connected through the ethernet link. I am new to gem5 internals and I appreciate any help with this.
I notice the use of attachSMMU at https://github.com/ARM-software/ATP-Engine/blob/be1066029d6256626b37be004e2a663fbc29f37e/gem5/baremetal_atp.py#L76 I could not find any other examples on SMMU, please let me know if you have any examples. I tried to change the ethernet device connection similarly in ARM bigLITTLE example configuration as below: Original function: https://github.com/gem5/gem5/blob/f29bfc0640c88a79eb7f94454ce31b3237ec0066/configs/example/arm/dist_bigLITTLE.py#L138 Before change: def addEthernet(system, options): # create NIC dev = IGbE_e1000() system.attach_pci(dev) system.ethernet = dev ... ... After change: def addEthernet(system, options): # create NIC dev = IGbE_e1000() system.realview.attachSmmu([dev],system.iobus) system.ethernet = dev ... ... With this change, I am getting the following warning and error: warn: system.realview.smmu adopting orphan SimObject param 'device_interfaces' AttributeError: Can't resolve proxy 'any' of type 'PciHost' from 'system.ethernet' Error in unproxying param 'host' of system.ethernet Again, I am new to gem5 internals and the above change might be completely wrong. I really appreciate any help in resolving this issue. Thanks, Chathura _______________________________________________ gem5-users mailing list -- gem5-users@gem5.org To unsubscribe send an email to gem5-users-le...@gem5.org
