* RDKEMW-4848: pass the proper handle to dsEnableHDCP

Copilot

Pull request overview

This PR refactors the dynamic library loading mechanism for device settings configuration to use a shared library handle instead of opening/closing the library multiple times. The changes introduce a centralized getDLInstance() and releaseDLInstance() pattern, and update all config loading methods to accept a handle parameter.

Key Changes

Centralized dynamic library handle management with thread-safe singleton pattern
Updated all config load methods to accept a void* pDLHandle parameter
Added support for FrontPanelConfig in the initialization flow
Removed the parse_opt_flag() function and associated delay logic

Reviewed changes

ds/frontPanelConfig.cpp

-														  configuration.pKIndicators[i].colorMode));
-				}
-		}
+    if (pDLHandle)


In the FrontPanelConfig::load method, the check for pDLHandle uses a different null comparison pattern (pDLHandle without nullptr comparison) compared to other config files which consistently use "nullptr != pDLHandle". Consider using "nullptr != pDLHandle" for consistency with the rest of the codebase.

Suggested change

if (pDLHandle)

if (nullptr != pDLHandle)

ds/frontPanelConfig.cpp

+    }
+    m_isFPConfigLoaded = true;
 	INT_INFO("Exit function\n");
+    return;


The explicit return statement at the end of a void function is unnecessary. Since this function returns void, the return statement at line 554 can be removed as the function will automatically return at its end.

Suggested change

return;

ds/videoDeviceConfig.cpp

+
+    if ( false == isDynamicConfigLoad)
 	{
 		INT_INFO("Read Old Configs\n");


The log message format for old config loading is inconsistent. In videoDeviceConfig.cpp line 164 it says "Read Old Configs" while other files (videoOutputPortConfig.cpp line 435, audioOutputPortConfig.cpp line 235, frontPanelConfig.cpp line 482) consistently use "Using OLD config loading". Consider updating this message to match the consistent pattern used elsewhere.

Suggested change

INT_INFO("Read Old Configs\n");

INT_INFO("Using OLD config loading\n");

ds/manager.cpp

+void* getDLInstance()
+{
+    std::lock_guard<std::mutex> lock(gDLMutex);
+    dlerror(); // clear old error
+    if (nullptr == gDLHandle){
+        gDLHandle = dlopen(RDK_DSHAL_NAME, RTLD_LAZY);
+    }
+    INT_INFO("%d:%s: DL Instance '%s'\n", __LINE__, __func__, (nullptr == gDLHandle ? "NULL" : "Valid"));
+    return gDLHandle;
+}


The getDLInstance function does not log or handle the error when dlopen fails. The old implementation would log the error message from dlerror(), but this new implementation only logs whether the handle is NULL or Valid. Consider logging the actual error message from dlerror() when dlopen fails to aid in debugging issues with loading the dynamic library.

ds/manager.cpp

+    void* pDLHandle = getDLInstance();
+	device::AudioOutputPortConfig::getInstance().load(pDLHandle);
+	device::VideoOutputPortConfig::getInstance().load(pDLHandle);
+	device::VideoDeviceConfig::getInstance().load(pDLHandle);


The Manager::load() method calls load for AudioOutputPortConfig, VideoOutputPortConfig, and VideoDeviceConfig, but does not call FrontPanelConfig::getInstance().load(pDLHandle). This is inconsistent with Manager::Initialize() which calls load on all four config classes including FrontPanelConfig. This inconsistency could lead to FrontPanelConfig not being properly loaded when Manager::load() is called.

Suggested change

device::VideoDeviceConfig::getInstance().load(pDLHandle);

device::VideoDeviceConfig::getInstance().load(pDLHandle);

device::FrontPanelConfig::getInstance().load(pDLHandle);
