From 4ef2af8c98354aea8a4a3758d798c6a2b7bf9321 Mon Sep 17 00:00:00 2001 From: Lioncash Date: Mon, 26 Nov 2018 18:23:12 -0500 Subject: svc: Implement svcCreateResourceLimit() This function simply creates a ResourceLimit instance and attempts to create a handle for it within the current process' handle table. If the kernal fails to either create the ResourceLimit instance or create a handle for the ResourceLimit instance, it returns a failure code (OUT_OF_RESOURCE, and HANDLE_TABLE_FULL respectively). Finally, it exits by providing the output parameter with the handle value for the ResourceLimit instance and returning that it was successful. Note: We do not return OUT_OF_RESOURCE because, if yuzu runs out of available memory, then new will currently throw. We *could* allocate the kernel instance with std::nothrow, however this would be inconsistent with how all other kernel objects are currently allocated. --- src/core/hle/kernel/svc.cpp | 20 +++++++++++++++++++- 1 file changed, 19 insertions(+), 1 deletion(-) (limited to 'src/core/hle/kernel/svc.cpp') diff --git a/src/core/hle/kernel/svc.cpp b/src/core/hle/kernel/svc.cpp index f287f7c97..4b7991c32 100644 --- a/src/core/hle/kernel/svc.cpp +++ b/src/core/hle/kernel/svc.cpp @@ -1346,6 +1346,24 @@ static ResultCode GetProcessInfo(u64* out, Handle process_handle, u32 type) { return RESULT_SUCCESS; } +static ResultCode CreateResourceLimit(Handle* out_handle) { + LOG_DEBUG(Kernel_SVC, "called"); + + auto& kernel = Core::System::GetInstance().Kernel(); + auto resource_limit = ResourceLimit::Create(kernel); + + auto* const current_process = kernel.CurrentProcess(); + ASSERT(current_process != nullptr); + + const auto handle = current_process->GetHandleTable().Create(std::move(resource_limit)); + if (handle.Failed()) { + return handle.Code(); + } + + *out_handle = *handle; + return RESULT_SUCCESS; +} + namespace { struct FunctionDef { using Func = void(); @@ -1482,7 +1500,7 @@ static const FunctionDef SVC_Table[] = { {0x7A, nullptr, "StartProcess"}, {0x7B, nullptr, "TerminateProcess"}, {0x7C, SvcWrap, "GetProcessInfo"}, - {0x7D, nullptr, "CreateResourceLimit"}, + {0x7D, SvcWrap, "CreateResourceLimit"}, {0x7E, nullptr, "SetResourceLimitLimitValue"}, {0x7F, nullptr, "CallSecureMonitor"}, }; -- cgit v1.2.3
