Tools

Tools that help the driver writing process:

  • EnvyTools - hardware register database, documentation and collection of RE tools (nvapeek, nvapoke, nvbios, envydis, etc.)
  • MmioTrace - traces memory mapped I/O access within kernel. Used to record how a driver module uses MMIO reads and writes.
  • Valgrind-mmt - modification of Valgrind which intercepts all traffic to the driver
  • Nouveau-PM

  • REnouveau (CVS) - dumps the modifications in the command fifo and user-mapped registers when a process emits rendering commands. Obsolete:

  • RulesNG - hardware register database (obsoleted by envytools).

  • Nouveau CVS repo - other tools and scripts (e.g. crashdump and createdump).

Debugging tools

  • OProfile is a useful statistical profiler, for a system wide performance overview.
