From baed7e1fba99c3f1932c6a41ad1496d1b6490a5a Mon Sep 17 00:00:00 2001 From: Lioncash Date: Wed, 3 Oct 2018 18:47:57 -0400 Subject: kernel/thread: Make all instance variables private Many of the member variables of the thread class aren't even used outside of the class itself, so there's no need to make those variables public. This change follows in the steps of the previous changes that made other kernel types' members private. The main motivation behind this is that the Thread class will likely change in the future as emulation becomes more accurate, and letting random bits of the emulator access data members of the Thread class directly makes it a pain to shuffle around and/or modify internals. Having all data members public like this also makes it difficult to reason about certain bits of behavior without first verifying what parts of the core actually use them. Everything being public also generally follows the tendency for changes to be introduced in completely different translation units that would otherwise be better introduced as an addition to the Thread class' public interface. --- src/core/hle/kernel/scheduler.cpp | 36 ++++++++++++++++++------------------ 1 file changed, 18 insertions(+), 18 deletions(-) (limited to 'src/core/hle/kernel/scheduler.cpp') diff --git a/src/core/hle/kernel/scheduler.cpp b/src/core/hle/kernel/scheduler.cpp index 1e82cfffb..cfd6e1bad 100644 --- a/src/core/hle/kernel/scheduler.cpp +++ b/src/core/hle/kernel/scheduler.cpp @@ -38,10 +38,10 @@ Thread* Scheduler::PopNextReadyThread() { Thread* next = nullptr; Thread* thread = GetCurrentThread(); - if (thread && thread->status == ThreadStatus::Running) { + if (thread && thread->GetStatus() == ThreadStatus::Running) { // We have to do better than the current thread. // This call returns null when that's not possible. - next = ready_queue.pop_first_better(thread->current_priority); + next = ready_queue.pop_first_better(thread->GetPriority()); if (!next) { // Otherwise just keep going with the current thread next = thread; @@ -58,22 +58,21 @@ void Scheduler::SwitchContext(Thread* new_thread) { // Save context for previous thread if (previous_thread) { - previous_thread->last_running_ticks = CoreTiming::GetTicks(); - cpu_core.SaveContext(previous_thread->context); + cpu_core.SaveContext(previous_thread->GetContext()); // Save the TPIDR_EL0 system register in case it was modified. - previous_thread->tpidr_el0 = cpu_core.GetTPIDR_EL0(); + previous_thread->SetTPIDR_EL0(cpu_core.GetTPIDR_EL0()); - if (previous_thread->status == ThreadStatus::Running) { + if (previous_thread->GetStatus() == ThreadStatus::Running) { // This is only the case when a reschedule is triggered without the current thread // yielding execution (i.e. an event triggered, system core time-sliced, etc) - ready_queue.push_front(previous_thread->current_priority, previous_thread); - previous_thread->status = ThreadStatus::Ready; + ready_queue.push_front(previous_thread->GetPriority(), previous_thread); + previous_thread->SetStatus(ThreadStatus::Ready); } } // Load context of new thread if (new_thread) { - ASSERT_MSG(new_thread->status == ThreadStatus::Ready, + ASSERT_MSG(new_thread->GetStatus() == ThreadStatus::Ready, "Thread must be ready to become running."); // Cancel any outstanding wakeup events for this thread @@ -83,15 +82,16 @@ void Scheduler::SwitchContext(Thread* new_thread) { current_thread = new_thread; - ready_queue.remove(new_thread->current_priority, new_thread); - new_thread->status = ThreadStatus::Running; + ready_queue.remove(new_thread->GetPriority(), new_thread); + new_thread->SetStatus(ThreadStatus::Running); - if (previous_process != current_thread->owner_process) { - Core::CurrentProcess() = current_thread->owner_process; + const auto thread_owner_process = current_thread->GetOwnerProcess(); + if (previous_process != thread_owner_process) { + Core::CurrentProcess() = thread_owner_process; SetCurrentPageTable(&Core::CurrentProcess()->VMManager().page_table); } - cpu_core.LoadContext(new_thread->context); + cpu_core.LoadContext(new_thread->GetContext()); cpu_core.SetTlsAddress(new_thread->GetTLSAddress()); cpu_core.SetTPIDR_EL0(new_thread->GetTPIDR_EL0()); cpu_core.ClearExclusiveState(); @@ -136,14 +136,14 @@ void Scheduler::RemoveThread(Thread* thread) { void Scheduler::ScheduleThread(Thread* thread, u32 priority) { std::lock_guard lock(scheduler_mutex); - ASSERT(thread->status == ThreadStatus::Ready); + ASSERT(thread->GetStatus() == ThreadStatus::Ready); ready_queue.push_back(priority, thread); } void Scheduler::UnscheduleThread(Thread* thread, u32 priority) { std::lock_guard lock(scheduler_mutex); - ASSERT(thread->status == ThreadStatus::Ready); + ASSERT(thread->GetStatus() == ThreadStatus::Ready); ready_queue.remove(priority, thread); } @@ -151,8 +151,8 @@ void Scheduler::SetThreadPriority(Thread* thread, u32 priority) { std::lock_guard lock(scheduler_mutex); // If thread was ready, adjust queues - if (thread->status == ThreadStatus::Ready) - ready_queue.move(thread, thread->current_priority, priority); + if (thread->GetStatus() == ThreadStatus::Ready) + ready_queue.move(thread, thread->GetPriority(), priority); else ready_queue.prepare(priority); } -- cgit v1.2.3
