From 7f48aa8d2580da6b3b83a389e31804e493aba69f Mon Sep 17 00:00:00 2001 From: Subv Date: Tue, 26 Sep 2017 18:17:47 -0500 Subject: [PATCH] Loaders: Don't automatically set the current process every time we load an application. The loaders will now just create a Kernel::Process, construct it and return it to the caller, which is responsible for setting it as the current process and configuring the global page table. --- src/core/core.cpp | 6 ++++-- src/core/loader/3dsx.cpp | 15 +++++++-------- src/core/loader/3dsx.h | 2 +- src/core/loader/elf.cpp | 15 +++++++-------- src/core/loader/elf.h | 2 +- src/core/loader/loader.h | 13 ++++++++----- src/core/loader/ncch.cpp | 19 +++++++++---------- src/core/loader/ncch.h | 5 +++-- 8 files changed, 40 insertions(+), 37 deletions(-) diff --git a/src/core/core.cpp b/src/core/core.cpp index 59b8768e71..0c7a729871 100644 --- a/src/core/core.cpp +++ b/src/core/core.cpp @@ -13,6 +13,7 @@ #include "core/core_timing.h" #include "core/gdbstub/gdbstub.h" #include "core/hle/kernel/kernel.h" +#include "core/hle/kernel/process.h" #include "core/hle/kernel/thread.h" #include "core/hle/service/service.h" #include "core/hw/hw.h" @@ -100,7 +101,7 @@ System::ResultStatus System::Load(EmuWindow* emu_window, const std::string& file return init_result;
