From dc39d06950de246094be9643313970125e0c49ee Mon Sep 17 00:00:00 2001 From: Yuri Kunde Schlesner Date: Fri, 17 Jul 2015 02:24:13 -0300 Subject: Ensure all kernel objects are released during shutdown This commit fixes several kernel object leaks. The most severe of them was threads not being removed from the private handle table used for CoreTiming events. This resulted in Threads never being released, which in turn held references to Process, causing CodeSets to never be freed when loading other applications. --- src/core/hle/kernel/thread.cpp | 21 ++++++++++++++------- src/core/hle/service/apt/apt.cpp | 3 +++ src/core/hle/service/dsp_dsp.cpp | 5 +++++ src/core/hle/service/dsp_dsp.h | 1 + src/core/hle/service/gsp_gpu.cpp | 7 ++++++- src/core/hle/service/gsp_gpu.h | 1 + src/core/hle/service/nwm_uds.cpp | 4 ++++ src/core/hle/service/nwm_uds.h | 1 + src/core/hle/service/srv.cpp | 4 ++++ src/core/hle/service/srv.h | 1 + src/core/hle/service/y2r_u.cpp | 4 ++++ src/core/hle/service/y2r_u.h | 1 + 12 files changed, 45 insertions(+), 8 deletions(-) (limited to 'src') diff --git a/src/core/hle/kernel/thread.cpp b/src/core/hle/kernel/thread.cpp index 4729a7fe..64166ab9 100644 --- a/src/core/hle/kernel/thread.cpp +++ b/src/core/hle/kernel/thread.cpp @@ -37,6 +37,10 @@ void Thread::Acquire() { ASSERT_MSG(!ShouldWait(), "object unavailable!");
