From 0cbcd6ec9aeeafc298fe2e6e4ac10d68bb7267c5 Mon Sep 17 00:00:00 2001 From: Lioncash Date: Tue, 28 Aug 2018 12:30:33 -0400 Subject: kernel: Eliminate kernel global state As means to pave the way for getting rid of global state within core, This eliminates kernel global state by removing all globals. Instead this introduces a KernelCore class which acts as a kernel instance. This instance lives in the System class, which keeps its lifetime contained to the lifetime of the System class. This also forces the kernel types to actually interact with the main kernel instance itself instead of having transient kernel state placed all over several translation units, keeping everything together. It also has a nice consequence of making dependencies much more explicit. This also makes our initialization a tad bit more correct. Previously we were creating a kernel process before the actual kernel was initialized, which doesn't really make much sense. The KernelCore class itself follows the PImpl idiom, which allows keeping all the implementation details sealed away from everything else, which forces the use of the exposed API and allows us to avoid any unnecessary inclusions within the main kernel header. --- src/core/core.cpp | 16 +- src/core/core.h | 8 + src/core/hle/ipc_helpers.h | 5 +- src/core/hle/kernel/client_port.cpp | 4 +- src/core/hle/kernel/client_port.h | 5 +- src/core/hle/kernel/client_session.cpp | 2 +- src/core/hle/kernel/client_session.h | 5 +- src/core/hle/kernel/event.cpp | 8 +- src/core/hle/kernel/event.h | 8 +- src/core/hle/kernel/handle_table.cpp | 2 - src/core/hle/kernel/handle_table.h | 2 - src/core/hle/kernel/hle_ipc.cpp | 17 +- src/core/hle/kernel/kernel.cpp | 283 ++++++++++++++++++++++-- src/core/hle/kernel/kernel.h | 89 +++++++- src/core/hle/kernel/mutex.cpp | 6 +- src/core/hle/kernel/mutex.h | 5 +- src/core/hle/kernel/object.cpp | 2 + src/core/hle/kernel/object.h | 10 +- src/core/hle/kernel/process.cpp | 40 +--- src/core/hle/kernel/process.h | 21 +- src/core/hle/kernel/resource_limit.cpp | 85 +------ src/core/hle/kernel/resource_limit.h | 19 +- src/core/hle/kernel/server_port.cpp | 10 +- src/core/hle/kernel/server_port.h | 6 +- src/core/hle/kernel/server_session.cpp | 17 +- src/core/hle/kernel/server_session.h | 14 +- src/core/hle/kernel/shared_memory.cpp | 20 +- src/core/hle/kernel/shared_memory.h | 13 +- src/core/hle/kernel/svc.cpp | 80 ++++--- src/core/hle/kernel/thread.cpp | 119 ++-------- src/core/hle/kernel/thread.h | 22 +- src/core/hle/kernel/timer.cpp | 45 +--- src/core/hle/kernel/timer.h | 13 +- src/core/hle/kernel/wait_object.cpp | 3 + src/core/hle/kernel/wait_object.h | 4 + src/core/hle/service/am/am.cpp | 9 +- src/core/hle/service/audio/audout_u.cpp | 4 +- src/core/hle/service/audio/audren_u.cpp | 8 +- src/core/hle/service/hid/hid.cpp | 9 +- src/core/hle/service/nfp/nfp.cpp | 10 +- src/core/hle/service/nifm/nifm.cpp | 6 +- src/core/hle/service/ns/pl_u.cpp | 3 +- src/core/hle/service/nvdrv/interface.cpp | 4 +- src/core/hle/service/nvflinger/buffer_queue.cpp | 4 +- src/core/hle/service/nvflinger/nvflinger.cpp | 3 +- src/core/hle/service/service.cpp | 9 +- src/core/hle/service/sm/sm.cpp | 5 +- src/core/loader/deconstructed_rom_directory.cpp | 4 +- src/core/loader/elf.cpp | 7 +- src/core/loader/nro.cpp | 6 +- src/core/loader/nso.cpp | 6 +- 51 files changed, 665 insertions(+), 440 deletions(-) (limited to 'src/core') diff --git a/src/core/core.cpp b/src/core/core.cpp index 07da4c493..2293669e5 100644 --- a/src/core/core.cpp +++ b/src/core/core.cpp @@ -171,6 +171,14 @@ const std::shared_ptr& System::Scheduler(size_t core_index) { return cpu_cores[core_index]->Scheduler();
