From 394095438ac5de4723954b1498cac8d677ddd4f5 Mon Sep 17 00:00:00 2001 From: Lioncash Date: Fri, 29 Mar 2019 13:26:19 -0400 Subject: [PATCH] common/thread: Remove unused functions Many of these functions are carried over from Dolphin (where they aren't used anymore). Given these have no use (and we really shouldn't be screwing around with OS-specific thread scheduler handling from the emulator, these can be removed. The function for setting the thread name is left, however, since it can have debugging utility usages. --- src/common/thread.cpp | 37 ------------------------------------- src/common/thread.h | 4 ---- 2 files changed, 41 deletions(-) diff --git a/src/common/thread.cpp b/src/common/thread.cpp index 5144c0d9f..fe7a420cc 100644 --- a/src/common/thread.cpp +++ b/src/common/thread.cpp @@ -27,18 +27,6 @@ namespace Common { #ifdef _MSC_VER -void SetThreadAffinity(std::thread::native_handle_type thread, u32 mask) { - SetThreadAffinityMask(thread, mask); -} - -void SetCurrentThreadAffinity(u32 mask) { - SetThreadAffinityMask(GetCurrentThread(), mask); -} - -void SwitchCurrentThread() { - SwitchToThread(); -} - // Sets the debugger-visible name of the current thread. // Uses undocumented (actually, it is now documented) trick. // http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vsdebug/html/vxtsksettingthreadname.asp @@ -70,31 +58,6 @@ void SetCurrentThreadName(const char* name) { #else // !MSVC_VER, so must be POSIX threads -void SetThreadAffinity(std::thread::native_handle_type thread, u32 mask) { -#ifdef __APPLE__ - thread_policy_set(pthread_mach_thread_np(thread), THREAD_AFFINITY_POLICY, (integer_t*)&mask, 1); -#elif (defined __linux__ || defined __FreeBSD__) && !(defined ANDROID) - cpu_set_t cpu_set; - CPU_ZERO(&cpu_set); - - for (int i = 0; i != sizeof(mask) * 8; ++i) - if ((mask >> i) & 1) - CPU_SET(i, &cpu_set); - - pthread_setaffinity_np(thread, sizeof(cpu_set), &cpu_set); -#endif -} - -void SetCurrentThreadAffinity(u32 mask) { - SetThreadAffinity(pthread_self(), mask); -} - -#ifndef _WIN32 -void SwitchCurrentThread() { - usleep(1000 * 1); -} -#endif - // MinGW with the POSIX threading model does not support pthread_setname_np #if !defined(_WIN32) || defined(_MSC_VER) void SetCurrentThreadName(const char* name) { diff --git a/src/common/thread.h b/src/common/thread.h index 2cf74452d..c5fc3533d 100644 --- a/src/common/thread.h +++ b/src/common/thread.h @@ -9,7 +9,6 @@ #include #include #include -#include "common/common_types.h" namespace Common { @@ -78,9 +77,6 @@ private: std::size_t generation = 0; // Incremented once each time the barrier is used }; -void SetThreadAffinity(std::thread::native_handle_type thread, u32 mask); -void SetCurrentThreadAffinity(u32 mask); -void SwitchCurrentThread(); // On Linux, this is equal to sleep 1ms void SetCurrentThreadName(const char* name); } // namespace Common
