Hi, Is there a way to access host devices (Eg : PCIE), from gem5 simulator in FS mode? In SE mode, we have access since it doesn't have its own OS and uses host OS to run the simulation. I need to get access to host devices similarly in FS mode as well. Appreciate your help. -- Thanks, Ashan

Hi All, Can anyone please give me a pointer to this?

Hi Ashan, In a FS simulation you would usually access a device with a driver. In general, it depends on the programming interface of your device.

Hi Giacomo*,* Thanks for your reply. In my host computer, if I do lspci it shows 20 connected controllers and devices. But in gem5 in FS mode it shows a single IDE as below. root@gem5-host:~# lspci 00:04.0 IDE interface: Intel Corporation 82371AB/EB/MB PIIX4 IDE root@gem5-host:~# Is this because not having drivers in Gem5 FS simulation? Can you please comment? My main target is to connect one of the pci devices from the host computer in Gem5 FS mode. (from above mentioned 20).
