[Qemu-devel] Qemu ARM9 weirdness

2014-03-24 Thread Joel Fernandes
Hi, I'm seeing some weirdness debugging a kernel on a ARM925 platform (cheetah, OMAP1 based). Qemu version: 2.0.0-rc0 I'm using GDB to step through a mainline Linux kernel, which crashes very early in boot (crash happens when reading the CPUID using cp15 instruction which is a different issue.)
