Hi All,
I am developing a simple Storport miniport for my storage device. But, now I am facing an interesting problem, that my debug prints through StorPortDebugPrint are not coming at all!!!. This started with a latest build of Vista that I installed a few days back.
The WDK documentation of StorPortDebugPrint says nt!kd_storport_mask to be set for supporting the system wide debug mechanism. My attempt to set this kernel variable through windbg didn’t succeed and I am getting an error message “-Couldn’t resolve error at ‘nt!Kd_StorPort_Mask’”. I don’t have the kernel symbols installed in my system, is that the reason for this error?
I have gone through the DbgPrintEx documentation and an the article in osr (http://www.osronline.com/article.cfm?article=295), both talk about how to set the debug filters in the registry. But interestingly that registry key itself (HKLM\SYSTEM\CCS\Control\Session Manager\Debug Print Filter) is not present in registry!!! I created the key “Debug Print Filter” under Session Manager and added the following dword values under that - IHVDRIVER, IHVBUS, and STORPORT, with mask value of 0xF. IHVDRIVER and IHVBUS are the documented values in WDK, and I have added STORPORT in the sameway thinking that it is of the same kind for enabling debug mask for storport component. This also not giving the result I am expecting.
Since I am experimenting manythings at this time with my miniport, I can’t survive without finding a solution to this problem:( Please let me know if i am doing something terribly wrong and suggest some solution.
thanks

Didn’t drew answer this on the windbg alias earlier today? You need kernel symbols for this to work so that you can resolve nt!Kd_storport_mask and edit the value appropriately

To access nt!kd_storport_mask, you need the symbol for ntoskrnl

Hi,
Thanks for the replys. I have installed the symbols, which allowed me to edit the kernel variable Kd_storport_mask. But still StorportDebugPrint is not outputing my debug prints!!!
I set value of Kd_storport_mask to 0xF. And my call to the debug function looks like this: StorPortDebugPrint(0,“\n**********Memory Config**************\n”).
So, what could be wrong with my settings? For getting the debugPrint levels from 0 to 3, what should be the value of the mask. My understanding is 0xf will serve the purpose.
thanks
