getJcpuidVersion
public static int getJcpuidVersion()Return the jcpuid version- Returns:
- 0 if no jcpuid available, 2 if version not supported
- Since:
- 0.9.26
-
getCPUVendorID
-
getCPUFamily
static int getCPUFamily()- Returns:
- 0-15
-
getCPUModel
static int getCPUModel()- Returns:
- 0-15
-
getCPUExtendedModel
static int getCPUExtendedModel()Only valid if family == 15, or, for Intel only, family == 6. Left shift by 4 and then add model to get full model.- Returns:

-
getCPUExtendedFamily
static int getCPUExtendedFamily()Only valid if family == 15. Add family to get full family.- Returns:
- 0-255
-
getCPUStepping
static int getCPUStepping()- Returns:
- 0-15
-
getEDXCPUFlags
static int getEDXCPUFlags() -
getECXCPUFlags
static int getECXCPUFlags() -
getExtendedECXCPUFlags
static int getExtendedECXCPUFlags() -
getExtendedEDXCPUFlags
static int getExtendedEDXCPUFlags()- Since:

-
getExtendedEBXFeatureFlags
static int getExtendedEBXFeatureFlags()- Since:
- 0.9.26
-
getExtendedECXFeatureFlags
static int getExtendedECXFeatureFlags()There's almost nothing in here.- Since:
- 0.9.26
-
getCPUModelName
The model name string, up to 48 characters, as reported by the processor itself.- Returns:
- trimmed string, null if unsupported
- Since:
- 0.9.16
-
getInfo
Returns a CPUInfo item for the current type of CPU If I could I would declare this method in a interface named CPUInfoProvider and implement that interface in this class. This would make it easier for other people to understand that there is nothing preventing them from coding up new providers, probably using other detection methods than the x86-only CPUID instruction- Throws:
UnknownCPUException
