Hello, I am investigating using valgrind for tracking MMIO access. Is it possible to configure valgrind to display reads and writes to memory locations if they can be determined? For example, debugging a XFree86 driver by looking at what what is written to different parts of memory. Obviously with instrumentation this would appear to be possible, but I am wondering if there is a valgrind skin that allows you to do something like... valgrind --skin=memwatch --region=000a0000-000c0000 X And consequently understand all the reads and writes (and possibly execution) of data and code in the BIOS. Looking forward to replies (and am more than willing to be a guinea pig!). Regards, Matthew |
