[edk2-devel] [PATCH v1 0/1] BoardModulePkg: Copy device path before processing

Posted by Abdul Lateef Attar via groups.io 2 years, 1 month ago

GCC compiler puts the DevicePath PCDs to the read-only
section. During boot if try to process the device path
after PtrGetPtr it throws a page fault exception.

Hence making a local copy using DuplicateDevicePath()
to avoid the page fault exception.
