From 8e4c9c9852b17082f9cb2e2b3d954dee6be7280f Mon Sep 17 00:00:00 2001 From: ameerj <52414509+ameerj@users.noreply.github.com> Date: Sat, 20 Feb 2021 20:51:11 -0500 Subject: [PATCH] kernel: Fix resource release exception on exit After rewriting the resource limit, objects releasing reserved resources require a live kernel instance. This commit fixes exceptions that occur due to the kernel being destroyed before some objects released their resources, allowing for a graceful exit. --- src/core/core.cpp | 3 +++ src/core/hle/kernel/kernel.cpp | 9 +++++++-- src/core/hle/service/time/time_manager.cpp | 4 ++++ src/core/hle/service/time/time_manager.h | 2 ++ 4 files changed, 16 insertions(+), 2 deletions(-) diff --git a/src/core/core.cpp b/src/core/core.cpp index 30f5e1128..de6305e2a 100644 --- a/src/core/core.cpp +++ b/src/core/core.cpp @@ -308,6 +308,9 @@ struct System::Impl { // Close all CPU/threading state cpu_manager.Shutdown(); + // Release the Time Manager's resources + time_manager.Shutdown(); + // Shutdown kernel and core timing core_timing.Shutdown(); kernel.Shutdown(); diff --git a/src/core/hle/kernel/kernel.cpp b/src/core/hle/kernel/kernel.cpp index b6e6f115e..39c5182c5 100644 --- a/src/core/hle/kernel/kernel.cpp +++ b/src/core/hle/kernel/kernel.cpp @@ -101,8 +101,6 @@ struct KernelCore::Impl { current_process = nullptr; - system_resource_limit = nullptr; - global_handle_table.Clear(); preemption_event = nullptr; @@ -111,6 +109,13 @@ struct KernelCore::Impl { exclusive_monitor.reset(); + hid_shared_mem = nullptr; + font_shared_mem = nullptr; + irs_shared_mem = nullptr; + time_shared_mem = nullptr; + + system_resource_limit = nullptr; + // Next host thead ID to use, 0-3 IDs represent core threads, >3 represent others next_host_thread_id = Core::Hardware::NUM_CPU_CORES; } diff --git a/src/core/hle/service/time/time_manager.cpp b/src/core/hle/service/time/time_manager.cpp index 858623e2b..1f7309f6b 100644 --- a/src/core/hle/service/time/time_manager.cpp +++ b/src/core/hle/service/time/time_manager.cpp @@ -279,6 +279,10 @@ const SharedMemory& TimeManager::GetSharedMemory() const { return impl->shared_memory; } +void TimeManager::Shutdown() { + impl.reset(); +} + void TimeManager::UpdateLocalSystemClockTime(s64 posix_time) { impl->UpdateLocalSystemClockTime(system, posix_time); } diff --git a/src/core/hle/service/time/time_manager.h b/src/core/hle/service/time/time_manager.h index 993c7c288..4db8cc0e1 100644 --- a/src/core/hle/service/time/time_manager.h +++ b/src/core/hle/service/time/time_manager.h @@ -61,6 +61,8 @@ public: const SharedMemory& GetSharedMemory() const; + void Shutdown(); + void SetupTimeZoneManager(std::string location_name, Clock::SteadyClockTimePoint time_zone_updated_time_point, std::size_t total_location_name_count, u128 time_zone_rule_version,
