Hi Matthias, thanks for the fast reply. Indeed I have already added the bus for PCI devices into the x86.vbus file as follows:
rtc => new System_bus() { # Add the RTC (PNP0B00) as a virtual device rtc => wrap(hw-root.match("PNP0B00")); }
con_bus => new System_bus() { ps2 => wrap(hw-root.match("PNP0303")); }
# Virtual bus for the fb-drv server fb => new System_bus() { # The BIOS memory regions to execute the VESA BIOS bios => wrap(hw-root.BIOS);
# PIT (accessd by various VESA BIOSes) pit => wrap(hw-root.match("PNP0100"));
# used for IO delay on various VESA BIOSes p80 => wrap(hw-root.match("P80"));
# Legacy VGA MMIO and I/O Ports vga => wrap(hw-root.match("PNP0900"));
# Use virtual PCI bus that keeps the physical bus structure # because the VESA BIOS may store the physical PCI address # when initialized by the host BIOS PCI0 => new PCI_bus_ident() { # Dummy device 0 on PCI bus 0 makes cirrus VESA BIOS happy host_bridge_dummy => new PCI_dummy_device();
# Put all display devices on our virtual PCI bus PCI class code 0x03 gfx[] => wrap(hw-root.match("PCI/CC_03")); } }
android_bus => new System_bus() { # Add a new virtual PCI root bridge PCI0 => new PCI_bus() { # Add all real PCI devices that match the CIDs to the virtual PCI bus # NOTE: PCI/CC_xx means PCI class code == xx. # CC_01 => storage devices # CC_02 => network devices # CC_04 => multimedia devices # CC_0c => serial bus devices (USB) pci[] => wrap(hw-root.match("PCI/CC_02")); } }
I guess the "pci[] => wrap(hw-root.match("PCI/CC_02"));" line should have been handling this, I checked also the l4 kernel and saw that the PCI device support was already chosen, still I can not achieve eth device on the virtualized android kernel
Best Regards

Dear all,
I have been working on running different linux based OSs on top of L4. Is there any documentation or tutorial where I might find information on how to make platform devices available for the linux OS running on top of L4. For instance, I could not get ethernet devices detected by the OS.
In case of a PCI device you simply add that to the respective vbus and compile the corresponding driver into L4Linux. Make sure to activate the virtual PCI bus driver in L4Linux.
Matthias.
