There's a range of software which appears to provide information about PCI devices. I've been looking at PCIScope, it gives you access to the PCI registers and there is a dump facility. I'm brand new to PCI though and I don't know how to translate the base address to the actual location of the MMIO registers. It feels like there's far too little information in the dump tab. <a href="http://envytools.readthedocs.io/en/latest/hw/mmio.html#gf100-mmio-map">http://envytools.readthedocs.io/en/latest/hw/mmio.html#gf100-mmio-map</a> Supposedly this page contains the Nvidia MMIO map for GF100 devies and onwards (GP102 here). What are we actually looking for in this dump? It was mentioned but never specified what can be found that would be helpful for achieving sync for the two panel halves.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> <li>You are the QA Contact for the bug.</li> <li>You are on the CC list for the bug.</li> </ul> </body> </html>
