Hi, This series adds stack trace support during IA32 and X64 CPU exceptions.
Informations like back trace, stack contents and image module names (that were part of the call stack) will be dumped out. The current limitation is that it relies on available frame pointers (GCC only) in order to successfully unwind the stack. (Sorry for the very long delay - I was very busy working on something else and then went to vacations) Jiewen, I have tested it with VS2015x86 and the stack trace just hanged when printing out the first EIP (that is, no frame pointer at all). Thanks!

That is, RIP may point to lower and higher addresses for any other PE/COFF images. Both IA32 & X64. (Thanks Andrew & Jiewen) * Fixed typo: unwond -> unwound. Both IA32 & X64. (Thanks Brian) v3 -> v4: * Validate all frame/stack pointer addresses before dereferencing them as requested by Brian & Jiewen. * Correctly print out IP addresses during the stack traces (by Jeff) Paulo Alcantara (6): UefiCpuPkg/CpuExceptionHandlerLib/X64: Add stack trace support UefiCpuPkg/CpuExceptionHandlerLib: Export GetPdbFileName() UefiCpuPkg/CpuExceptionHandlerLib/Ia32: Add stack trace support UefiCpuPkg/CpuExceptionHandlerLib: Add helper to valid memory addresses UefiCpuPkg/CpuExceptionHandlerLib: Ensure valid frame/stack pointers UefiCpuPkg/CpuExceptionHandlerLib: Correctly print IP addresses UefiCpuPkg/Library/CpuExceptionHandlerLib/CpuExceptionCommon.c | 484 ++++++++++++++++++-- UefiCpuPkg/Library/CpuExceptionHandlerLib/CpuExceptionCommon.h | 41 +- UefiCpuPkg/Library/CpuExceptionHandlerLib/Ia32/ArchExceptionHandler.c | 445 +++++++++++++++++- UefiCpuPkg/Library/CpuExceptionHandlerLib/X64/ArchExceptionHandler.c | 384 +++++++++++++++- 4 files changed, 1296 insertions(+), 58 deletions(-) -- 2.14.3 _______________________________________________ edk2-devel mailing list edk2-devel@lists.01.org https://lists.01.org/mailman/listinfo/edk2-devel
