From c73841500a7bf98f9f4006d25507b7b596257cbd Mon Sep 17 00:00:00 2001 From: bunnei Date: Fri, 17 Dec 2021 16:05:51 -0800 Subject: core: hle: Remove global HLE lock. - This was added early on as a hack to protect against some concurrency issues. - It's not clear that this serves any purpose anymore, and if it does, individual components should be fixed rather than using a global recursive mutex. --- src/core/hle/kernel/k_process.cpp | 2 -- src/core/hle/kernel/svc.cpp | 9 --------- 2 files changed, 11 deletions(-) (limited to 'src/core/hle/kernel') diff --git a/src/core/hle/kernel/k_process.cpp b/src/core/hle/kernel/k_process.cpp index 90dda40dc..aee313995 100644 --- a/src/core/hle/kernel/k_process.cpp +++ b/src/core/hle/kernel/k_process.cpp @@ -28,7 +28,6 @@ #include "core/hle/kernel/k_thread.h" #include "core/hle/kernel/kernel.h" #include "core/hle/kernel/svc_results.h" -#include "core/hle/lock.h" #include "core/memory.h" namespace Kernel { @@ -543,7 +542,6 @@ void KProcess::FreeTLSRegion(VAddr tls_address) { } void KProcess::LoadModule(CodeSet code_set, VAddr base_addr) { - std::lock_guard lock{HLE::g_hle_lock}; const auto ReprotectSegment = [&](const CodeSet::Segment& segment, KMemoryPermission permission) { page_table->SetProcessMemoryPermission(segment.addr + base_addr, segment.size, permission); diff --git a/src/core/hle/kernel/svc.cpp b/src/core/hle/kernel/svc.cpp index a9f7438ea..bb9475c56 100644 --- a/src/core/hle/kernel/svc.cpp +++ b/src/core/hle/kernel/svc.cpp @@ -41,7 +41,6 @@ #include "core/hle/kernel/svc_results.h" #include "core/hle/kernel/svc_types.h" #include "core/hle/kernel/svc_wrap.h" -#include "core/hle/lock.h" #include "core/hle/result.h" #include "core/memory.h" #include "core/reporter.h" @@ -137,7 +136,6 @@ enum class ResourceLimitValueType { /// Set the process heap to a given Size.
