Question about system architecture, noux and interprocess communication
by J.M. Becker 01 Nov '13

01 Nov '13

First I wanted to say, I've been following Genode for about a year and I'm very excited about its progress. My question has to do with Noux and how communication is done between processes, and the eventual porting of D-Bus. I'm unsure about just how isolated each noux process is, from other noux processes, and how something like d-bus could share information between running processes. In addition does each process always execute in it's own noux? and if so how could something like a ps command get information about all running processes? I'm just trying to get a handle of things before jumping in and attempting to port additional components. Thank you, -J.

I want to boot my system with genode-2010-11.iso file(To check live CD demonstration). I first did it in virtual box, i got booted. Now i want to check with realistic booting. I have burnt cd using this iso file, followed instructions in genode.org about system configuration check up and all, and then gave boot options : Boot with cd-dvd and saved but i am not able to boot. Can somebody suggest me some options for it? Maloth Naresh IITM

PCI passthrough in vancouver
by Salscheider, Niels Ole 23 Oct '13

23 Oct '13

Hello, I am trying to implement PCI passthrough in vancouver when using NOVA. For PCI passthrough, I have to handle MessageHostOp::OP_ATTACH_MSI (amongst others). This requires modifications to the Irq_connection / Irq_session. My current plan is to pass the bdf value through to the Irq_proxy_component, where I can use it to get the pci config space. This is then passed to the assign_gsi syscall. Apart from that, I have added two functions to read back the msi address and data. However, my current implementation hangs when I try to get the first device from a Pci::Connection in Irq_proxy_component. Does it make sense to pass the bdf value to the Irq_proxy_component or would you suggest another way to design the Irq_connection interface?
