Hi all, This is primarily targeted at Gabe but I welcome any other advice from people working with the x86 ISA model.
I am trying to get an x86_64 Ubuntu 11.04 filesystem to work with Gem5 and am running into some problems with the kernel. The provided kernels on the gem5 page are just a bit too old to work with a current ubuntu file system, Upstart complains on boot and I get a kernel panic. Some searching turned up that older kernels don't work with current versions of Ubuntu. So I have an unmodified 2.6.32-40-generic kernel with debug symbols from the ddebs repo. So far it is failing trying to set up the APIC timers, the 8254 with the 8259A APIC. The kernel panics after it tries numerous IRQ setups and fails (IRQ0 through 8259A, timer as a Virtual Wire IRQ, timer as ExtINT IRQ). Is there any documentation about these devices around that was used to develop the x86 setup? Does anyone have any knowledge about what the newer kernels assume that may break gem5? Thanks, Geoff _______________________________________________ gem5-users mailing list [email protected] http://m5sim.org/cgi-bin/mailman/listinfo/gem5-users
