From c0a01f3adc466d07fc27020048e82cca60988970 Mon Sep 17 00:00:00 2001 From: Lioncash Date: Fri, 22 Mar 2019 14:51:36 -0400 Subject: kernel/codeset: Make CodeSet's memory data member a regular std::vector The use of a shared_ptr is an implementation detail of the VMManager itself when mapping memory. Because of that, we shouldn't require all users of the CodeSet to have to allocate the shared_ptr ahead of time. It's intended that CodeSet simply pass in the required direct data, and that the memory manager takes care of it from that point on. This means we just do the shared pointer allocation in a single place, when loading modules, as opposed to in each loader. --- src/core/hle/kernel/code_set.h | 3 +-- src/core/hle/kernel/process.cpp | 6 ++++-- src/core/loader/elf.cpp | 2 +- src/core/loader/nro.cpp | 2 +- src/core/loader/nso.cpp | 2 +- 5 files changed, 8 insertions(+), 7 deletions(-) (limited to 'src') diff --git a/src/core/hle/kernel/code_set.h b/src/core/hle/kernel/code_set.h index 834fd23d2..879957dcb 100644 --- a/src/core/hle/kernel/code_set.h +++ b/src/core/hle/kernel/code_set.h @@ -5,7 +5,6 @@ #pragma once #include -#include #include #include "common/common_types.h" @@ -78,7 +77,7 @@ struct CodeSet final { } /// The overall data that backs this code set. - std::shared_ptr> memory; + std::vector memory; /// The segments that comprise this code set. std::array segments; diff --git a/src/core/hle/kernel/process.cpp b/src/core/hle/kernel/process.cpp index 0d782e4ba..87779a71c 100644 --- a/src/core/hle/kernel/process.cpp +++ b/src/core/hle/kernel/process.cpp @@ -210,11 +210,13 @@ void Process::FreeTLSSlot(VAddr tls_address) { } void Process::LoadModule(CodeSet module_, VAddr base_addr) { + const auto memory = std::make_shared>(std::move(module_.memory)); + const auto MapSegment = [&](const CodeSet::Segment& segment, VMAPermission permissions, MemoryState memory_state) { const auto vma = vm_manager - .MapMemoryBlock(segment.addr + base_addr, module_.memory, - segment.offset, segment.size, memory_state) + .MapMemoryBlock(segment.addr + base_addr, memory, segment.offset, + segment.size, memory_state) .Unwrap(); vm_manager.Reprotect(vma, permissions); }; diff --git a/src/core/loader/elf.cpp b/src/core/loader/elf.cpp index 8b1920f22..46ac372f6 100644 --- a/src/core/loader/elf.cpp +++ b/src/core/loader/elf.cpp @@ -341,7 +341,7 @@ Kernel::CodeSet ElfReader::LoadInto(VAddr vaddr) { } codeset.entrypoint = base_addr + header->e_entry; - codeset.memory = std::make_shared>(std::move(program_image)); + codeset.memory = std::move(program_image); LOG_DEBUG(Loader, "Done loading."); diff --git a/src/core/loader/nro.cpp b/src/core/loader/nro.cpp index 5de02a94b..31e4a0c84 100644 --- a/src/core/loader/nro.cpp +++ b/src/core/loader/nro.cpp @@ -187,7 +187,7 @@ static bool LoadNroImpl(Kernel::Process& process, const std::vector& data, program_image.resize(static_cast(program_image.size()) + bss_size); // Load codeset for current process - codeset.memory = std::make_shared>(std::move(program_image)); + codeset.memory = std::move(program_image); process.LoadModule(std::move(codeset), load_base); // Register module with GDBStub diff --git a/src/core/loader/nso.cpp b/src/core/loader/nso.cpp index 0eb9fd7f7..5caceb267 100644 --- a/src/core/loader/nso.cpp +++ b/src/core/loader/nso.cpp @@ -178,7 +178,7 @@ std::optional AppLoader_NSO::LoadModule(Kernel::Process& process, } // Load codeset for current process - codeset.memory = std::make_shared>(std::move(program_image)); + codeset.memory = std::move(program_image); process.LoadModule(std::move(codeset), load_base); // Register module with GDBStub -- cgit v1.2.3
