[Qemu-devel] memory trace with qemu |

Hello, I need qemu to keep track of all the memory access made by the guest, including read, write and the instruction fetches.I was using Simics to acomplish this task, but it is very slow.
I need the virtual address, the size of the operation, the cycle number when it happened and if it is a read, write or instruction fetch.
Reading the mail list archives, I saw that the file softmmu_header.h is always called when a read/write happens.
Is that so? Any ideas of how I can record these information with qemu?
Thanks in advance
