HWCAP_DCPOP The ARMv8.2-DCPoP feature introduces persistent memory support to theĪrchitecture, by defining a point of persistence in the memory Processor consistent (RCpc) model, which is weaker than theįunctionality implied by ID_AA64ISAR1_EL1.LRCPC = 0b0001. HWCAP_LRCPC ARMv8.3 adds new instructions to support Release Consistent Multiplication and addition of complex numbers.įunctionality implied by ID_AA64ISAR1_EL1.FCMA = 0b0001. HWCAP_FCMA ARM v8.3 adds support for new instructions to aid floating-point HWCAP_JSCVT ARMv8.3 adds support for a new instruction to perform conversionįrom double precision floating point to integer to match theĪrchitected behaviour of the equivalent Javascript conversion.įunctionality implied by ID_AA64ISAR1_EL1.JSCVT = 0b0001. HWCAP_ASIMDRDM Indicates whether Rounding Double Multiply (RDM) instructions are implemented for Advanced SIMD.įunctionality implied by ID_AA64ISAR0_EL1.RDM = 0b0001. These ID registers may imply the availability of features. HWCAP_CPUID EL0 access to certain ID registers is available, to the extentĭescribed by Documentation/arm64/cpu-feature-registers.txt. ![]() HWCAP_ASIMDHP Indicates whether the Advanced SIMD and Floating-point extension supports half-precision floating-point conversion operations.įunctionality implied by ID_AA64PFR0_EL1.AdvSIMD = 0b0001.
