SDR.CPUID
Description
This module is for detecting which SIMD instruction sets your CPU supports. In particular, it can detect SSE4.2, AVX and AVX2.
Synopsis
- cpuid :: Word32 -> IO (Word32, Word32, Word32, Word32)
- cpuidExtended :: Word32 -> Word32 -> IO (Word32, Word32, Word32, Word32)
- data CPUInfo = CPUInfo {}
- getCPUInfo :: IO CPUInfo
- hasSSE42 :: CPUInfo -> Bool
- hasAVX :: CPUInfo -> Bool
- hasAVX2 :: CPUInfo -> Bool
- featureSelect :: CPUInfo -> a -> [(CPUInfo -> Bool, a)] -> a
Raw CPUID
Execute the CPUID instruction
Arguments
| :: Word32 | Operation (EAX) |
| -> Word32 | ECX |
| -> IO (Word32, Word32, Word32, Word32) | Result (EAX, EBX, ECX, EDX) |
Execute the CPUID instruction setting ECX as well
