Great, so you've managed to get Linux running under KVM on e500? Rahul>> Yes. I can run Linux under kvm on a e500 based platform Option 2 requires that qemu set up the initial VM state exactly how firmware would have. That means loading the same kernel executable into the same memory location, same initial register state, initial TLB mappings, same (emulated) system hardware state, etc. For Linux, we used option 2. After loading the ELF file into guest memory, qemu creates the device tree (hierarchical data structure describing the physical system) and passes its address to Linux in a GPR, which is a job usually performed by u-boot. The decision really depends on the functionality and complexity of your firmware. Rahul>>I'll start with option 2. Initial goal would be to run a NetBSD guest on an emulated e500/8544 platform - which Liu has added support for recently in qemu/kvm to run as a linux guest. Our eventual goal is to emulate an e500/8548 CDS based platform.. Since KVM supports a NetBSD 4.0 guest (I think) and 8544/e500 emulation is already present in qemu -- theoretically the first part should work...but I recall Liu mentioning that there might be some OS specific quirks present in the port...and that was what I my question was hinting at earlier.. -- Hollis Blanchard IBM Linux Technology Centera -- To unsubscribe from this list: send the line "unsubscribe kvm-ppc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
