I agree there is a certain elegance to merging both translations, but I am concerned that existing EDK2 code may deal poorly with I/O addresses that require more than 32 bits to express. Did you try the mm command in the shell for instance? As you know, I recently removed an artificial address range limit there, but I wonder if it uses 64-bit variables for I/O ports. _______________________________________________ edk2-devel mailing list edk2-devel@lists.01.org https://lists.01.org/mailman/listinfo/edk2-devel
