<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Times New Roman","serif";color:#1F497D">You can enable prints within your WinDbg session by typing the following command:<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Times New Roman","serif";color:#1F497D"><o:p> </o:p></span></p>

<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Times New Roman","serif";color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Times New Roman","serif";color:#1F497D">Note that the mask indicates the level of verbosity. The verbosity is set for each print in the code by the first parameter (in your example below, INFO
is the verbosity level). You can also enter a registry value for enabling prints from the Windows NVMe miniport… however, I would not recommend this if you are going to be running normal I/O as the performance will come to a crawl during reads and writes.
But there are many articles on how to do this… you’ll just need to find the correct nvme.sys location in registry. Here is an OSR article on how to enable in the registry. Keep in mind if you just want the nvme.sys debug prints, you’ll need to find the correct
location for the nvme.sys driver in the registry.<o:p></o:p></span></p>

<p class="MsoNormal">Hi all,<o:p></o:p></p>

<p class="MsoNormal">Sorry for the elementary question, but how does one turn on print messages like:<o:p></o:p></p>

<p class="MsoNormal">Can a function() or a #define be written/set in code? Does it have to be compiled in a debug compile? How is this seen? Could it be viewed in debugview.exe?<o:p></o:p></p>
