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:

• A modified NVClock which can read/write all the nVidia registers. (obsoleted by envytools)

• PGTest - collection of simple tools useful for RE (obsoleted by envytools)

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

• Nvtrace - variant of valgrind-mmt which aimed to intercept all traffic to the driver (obsoleted by current valgrind-mmt)

• 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.
