This pull request introduces enhancements to the
System.Runtime.Cachinglibrary to support a new configuration parameter,physicalMemoryBytesAvailable, which allows finer control over memory pressure calculations. The changes primarily focus on extending configuration options, updating memory monitoring logic, and improving cross-platform compatibility.Configuration Enhancements:
physicalMemoryBytesAvailableas a new configuration property inMemoryCacheElement, enabling direct specification of available physical memory for cache management.Memory Monitoring Logic Updates:
PhysicalMemoryMonitorto support the newphysicalMemoryBytesAvailableparameter, allowing memory pressure calculations based on explicit memory values or GC thresholds.MemoryCacheStatisticsto initialize and manage thephysicalMemoryBytesAvailableconfiguration parameter.Cross-Platform Compatibility:
MemoryMonitor.Unix.csto improve support for Unix-based platforms, leveraging GC memory info for physical memory calculations.GetCurrentPressuremethods inPhysicalMemoryMonitor.Unix.csandPhysicalMemoryMonitor.Windows.csto use a legacy approach for backward compatibility.
