CPU INFOrmation library
cpuinfo is a library to detect essential for performance optimization information about host CPU. Planned features:
- Processor (SoC) name detection
- [ ] Using CPUID leaves 0x80000002–0x80000004 on x86/x86-64
- [ ] Using
/proc/cpuinfo
on ARM - [ ] Using kernel log (
dmesg
) on ARM - [ ] Using
ro.chipname
, ro.board.platform
, ro.product.board
properties (Android)
- Vendor and microarchitecture detection
- [x] Intel-designed x86/x86-64 cores (up to Kaby Lake, Airmont, and Knights Mill)
- [x] AMD-designed x86/x86-64 cores (up to Puma/Jaguar and Zen)
- [ ] VIA-designed x86/x86-64 cores
- [ ] Other x86 cores (DM&P, RDC, Transmeta, Cyrix, Rise)
- [x] ARM-designed ARM cores (up to Cortex-A17, Cortex-73)
- [x] Qualcomm-designed ARM cores (up to Kryo and Kryo-280)
- [x] nVidia-designed ARM cores (Denver)
- [x] Samsung-designed ARM cores (Mongoose)
- [x] Intel-designed ARM cores (XScale up to 3rd-gen)
- [ ] Apple-designed ARM cores (up to Hurricane)
- [ ] Server ARM cores
- Instruction set detection
- [x] Using CPUID on x86/x86-64 (Linux, Mach)
- [x] Using dynamic code generation validator on x86-64 (Native Client)
- [x] Using
/proc/cpuinfo
on 32-bit ARM EABI (Linux) - [x] Using microarchitecture heuristics on 32-bit ARM
- [x] Using
FPSID
and WCID
registers on 32-bit ARM - [ ] Using
getauxval
or /proc/self/auxv
(Linux) - [ ] Using instruction probing on ARM (Linux)
- Cache detection
- [x] Using CPUID leaf 0x00000002 on x86/x86-64
- [x] Using CPUID leaf 0x00000004 on non-AMD x86/x86-64
- [ ] Using CPUID leaves 0x80000005-0x80000006 on AMD x86/x86-64
- [x] Using CPUID leaf 0x8000001D on AMD x86/x86-64
- [x] Using
/proc/cpuinfo
on ARMv6 and earlier (Linux) - [x] Using microarchitecture heuristics on 32-bit ARM
- [x] Using
sysctlbyname
(Mach) - [ ] Using sysfs (Linux)
- [ ] Using
clGetDeviceInfo
with CL_DEVICE_GLOBAL_MEM_CACHE_SIZE
/CL_DEVICE_GLOBAL_MEM_CACHELINE_SIZE
parameters (Android)
- TLB detection
- [x] Using CPUID leaf 0x00000002 on x86/x86-64

- Topology detection
- [x] Using CPUID leaf 0x00000001 on x86/x86-64 (legacy APIC ID)
- [x] Using CPUID leaf 0x0000000B on x86/x86-64 (Intel APIC ID)
