From 45d5165426ae3ceb35e2c35ad675e7dacd2aa59e Mon Sep 17 00:00:00 2001 From: Ard Biesheuvel Date: Fri, 10 Feb 2023 15:08:59 +0100 Subject: [PATCH] efi: Add mixed-mode thunk recipe for GetMemoryAttributes EFI mixed mode on x86 requires a recipe for each protocol method or firmware service that takes u64 arguments by value, or returns pointer or 'native int' (UINTN) values by reference (e.g,, through a void ** or unsigned long * parameter), due to the fact that these types cannot be translated 1:1 between the i386 and MS x64 calling conventions. So add the missing recipe for GetMemoryAttributes, which is not actually being used yet on x86, but the code exists and can be built for x86 so let's make sure it works as it should.
