1. So far, only qemux86[-64] support hw breakpoint, no matter whether or not with kvm. qemuppc: The oe-core configuration uses a PPC G4 system as the default cpu but qemu doesn't simulate the hw breakpoint register for G4. qemuarm: The arch more than v7 supports hw breakpoint, however arm use v5 as default. qemuarm64: We temporarily drop qemuarm64 for the moment. Normally it will print debug info once, but endlessly when we trigger the break point. Now it is hard to located the issue, but we will confirm it later. qemumips*: Kernel dosen't support hw bp for mips. 2. Syslog maybe not started, so we use dmesg to confirm. 3. Running 'ls' to trigger the hardware breakpoint test.
