iCPUID 1.0.5

What is iCPUID?

iCPUID is a lightweight cross-platform implementation that allows us to obtain the CPUID information. Works on Windows, Mac and Linux.

Usage

Call CPUID.Instance.Leafs for getting all CPUID implemented leafs.

Examples

1. Detection of the availability of the CPUID instruction.

   CPUID cpuid = CPUID.Instance;
   Console.WriteLine($@" Is Available > {cpuid.IsAvailable}");
   

2. Gets and prints all CPUID implemented leafs.

   CPUID cpuid = CPUID.Instance;
   ReadOnlyCollection<Leaf> leafs = cpuid.ImplementedLeafs;
   foreach (Leaf leaf in leafs)
   {
       Console.WriteLine($@" {(int)leaf:X8}-{leaf}");
   }
   

3. Gets and prints all CPUID implemented leafs > sub-leafs.

   CPUID cpuid = CPUID.Instance;
   ReadOnlyCollection<Leaf> leafs = cpuid.ImplementedLeafs;
   foreach (var (leaf, subLeafs) in leafs)
   {
       Console.WriteLine($@" > {leaf} (EAX={(int)leaf:X8})");
   
       foreach (var subLeaf in subLeafs)
       {
           Console.WriteLine($@"   > {subLeaf.SubLeaf} (ECX={(int)subLeaf.SubLeaf:X8})");
       }
   }
   

4. Gets and prints all CPUID implemented leafs > sub-leafs (shows description).

   CPUID cpuid = CPUID.Instance;
   ReadOnlyCollection<Leaf> leafs = cpuid.ImplementedLeafs;
   foreach (var (leaf, subLeafs) in leafs)
   {
       Console.WriteLine($@" > {leaf} (EAX={(int)leaf:X8})");
   
       foreach (var subLeaf in subLeafs)
       {
           Console.WriteLine($@"   > {subLeaf.SubLeaf} (ECX={(int)subLeaf.SubLeaf:X8})");
           IEnumerable<IPropertyKey> properties = subLeaf.ImplementedProperties;
           foreach (var property in properties)
           {
               string friendlyName = GetFriendlyName(property);
               PropertyUnit unit = property.PropertyUnit;
               string description = property.GetPropertyDescription();
   
               Console.WriteLine($@"     > {friendlyName} {(unit == PropertyUnit.None ? string.Empty : $"({unit})")}: {description}");
           }
       }
   }
   

5. Gets and prints all CPUID implemented leafs > sub-leafs (values).

   CPUID cpuid = CPUID.Instance;
   ReadOnlyCollection<Leaf> leafs = cpuid.ImplementedLeafs;
   foreach (var (leaf, subLeafs) in leafs)
   {
       Console.WriteLine($@" > {leaf} (EAX={(int)leaf:X8})");
   
       foreach (var subLeaf in subLeafs)
       {
           Console.WriteLine($@"   > {subLeaf.SubLeaf} (ECX={(int)subLeaf.SubLeaf:X8})");
           IEnumerable<IPropertyKey> properties = subLeaf.ImplementedProperties;
           foreach (var property in properties)
           {
               QueryPropertyResult queryResult = subLeaf.GetProperty(property);
               PropertyItem propertyItem = queryResult.Value;
               object value = propertyItem.Value;
               string friendlyName = GetFriendlyName(property);
               PropertyUnit valueUnit = property.PropertyUnit;
               string unit = valueUnit == PropertyUnit.None ? string.Empty : valueUnit.ToString();
   
               if (value == null)
               {
                   Console.WriteLine($@"     > {friendlyName}: NULL");
                   continue;
               }
   
               if (value is bool)
               {
                   Console.WriteLine($@"     > {friendlyName}: {value} [{((bool)value ? 1 : 0)}]");
               }
               else if (value is string)
               {
                   Console.WriteLine($@"     > {friendlyName}: {value} {unit}");
               }
               else if (value is byte)
               {
                   Console.WriteLine($@"     > {friendlyName}: {value} {unit} [{value:X2}h]");
               }
               else if (value is int)
               {
                   Console.WriteLine($@"     > {friendlyName}: {value} {unit} [{value:X4}h]");
               }
               else if (value is uint)
               {
                   Console.WriteLine($@"     > {friendlyName}: {value} {unit} [{value:X4}h]");
               }
               else if (value is ulong)
               {
                   Console.WriteLine($@"     > {friendlyName}: {value} {unit} [{value:X8}h]");
               }
               else if (value.GetType() == typeof(ReadOnlyCollection<string>))
               {
                   Console.WriteLine($@"     > {friendlyName}");
                   var collection = (ReadOnlyCollection<string>)value;
                   foreach (var entry in collection)
                   {
                       Console.WriteLine($@"       > {entry} {unit}");
                   }
               }
               else
               {
                   Console.WriteLine($@"     > {friendlyName}: {value} {unit}");
               }
           }
       }
   }
   

6. Gets a single property directly.

   CPUID cpuid = CPUID.Instance;
   QueryPropertyResult manufacturerQueryResult = cpuid.Leafs.GetProperty(LeafProperty.BasicInformation.Manufacturer);
   if (manufacturerQueryResult.Success)
   {
       Console.WriteLine($@" > Manufacturer: {manufacturerQueryResult.Value.Value}");
   }
   
   QueryPropertyResult avx2 = cpuid.Leafs.GetProperty(LeafProperty.ExtendedFeatures.AVX2);
   if (avx2.Success)
   {
       Console.WriteLine($@" > AVX2: {avx2.Value.Value}");
   }
   

7. Gets a property in multiple elements directly.

   CPUID cpuid = CPUID.Instance;
   QuerySubLeafPropertyCollectionResult cacheSizesQueryResult = leafs.GetProperties(LeafProperty.DeterministicCacheParameters.CacheSize);
   if (cacheSizesQueryResult.Success)
   {
       CpuidSubLeafDictionary cacheSizes = cacheSizesQueryResult.Value;
       bool hasCacheSizesEntries = cacheSizes.Any();
       if (!hasCacheSizesEntries)
       {
           Console.WriteLine($@" > Sorry, The 'LeafProperty.DeterministicCacheParameters.CacheSize' property has not implementes on this system");
       }
       else
       {
           foreach (var (subLeaf, propertyItem) in cacheSizes)
           {
               Console.WriteLine($@" > Cache Size:  ({subLeaf}) > {propertyItem.Value}");
           }
       }
   }
