In Library constructor, "SMST->SmmRegisterProtocolNotify()" is used to register notification function for Protocol gEtiSmmguid(for example). This library is included in one SMM driver. In entry point of driver, some of the condition checks are failing so ERROR status is returned from Entry point. As ERROR status is returned from entry point, image is getting unloaded from memory. When gEtiSmmguid is installed in some other SMM driver, system is hanging as it is looking for Registered context and could not find it as the driver has already been unloaded. For DXE case, I use Library destructor to close the registered/created event but I don't find any way for SMM case. Is there any way to unregister the function which was registered with SMST->SmmRegisterProtocolNotify() ? Please give your suggestions. Note: Returning EFI_SUCCESS from entry point of the driver where the library is included resolves the issue but I am looking for a better solution.

Google/Bing gdb tutorial You should be able to run the backtrace command and see the stack frame. You can only see locals for the frame that your are currently in, assuming the compiler has not optimized the value into a register. The only difference between remote and local debugging with gdb is you don't use the file and run commands, and for EFI you use add-symbol-file to get symbols loaded. Note you need to add-symbol-file for every module to get full source level debug.

To: "[email protected]" <[email protected]> Message-ID: <[email protected]> Content-Type: text/plain; charset="us-ascii" I need to get the information of the slot in which my controller is connected and what I was trying is to use SMBIOS system configuration table. But when my driver is loaded from OptionROM the table was not populated, but If I load the driver from shell I am able to get the information. Do any of you know another method to get PCI Slot information from boot services driver?
