It follows that if the riscv_hwprobe +// syscall is not available then neither is the Vector extension (which needs kernel support). +// The riscv_hwprobe syscall should then be all we need to detect the Vector extension. +// However, some RISC-V board manufacturers ship boards with an older kernel on top of which +// they have back-ported various versions of the Vector extension patches but not the riscv_hwprobe +// patches. These kernels advertise support for the Vector extension using HWCAP. Falling +// back to HWCAP to detect the Vector extension, if riscv_hwprobe is not available, or simply not +// bothering with riscv_hwprobe at all and just using HWCAP may then seem like an attractive option. +// +// Unfortunately, simply checking the 'V' bit in AT_HWCAP will not work as this bit is used by +// RISC-V board and cloud instance providers to mean different things. The Lichee Pi 4A board +// and the Scaleway RV1 cloud instances use the 'V' bit to advertise their support for the unratified +// 0.7.1 version of the Vector Specification. The Banana Pi BPI-F3 and the CanMV-K230 board use +// it to advertise support for 1.0 of the Vector extension. Versions 0.7.1 and 1.0 of the Vector +// extension are binary incompatible. HWCAP can then not be used in isolation to populate the +// HasV field as this field indicates that the underlying CPU is compatible with RVV 1.0. +// +// There is a way at runtime to distinguish between versions 0.7.1 and 1.0 of the Vector +// specification by issuing a RVV 1.0 vsetvli instruction and checking the vill bit of the vtype +// register. This check would allow us to safely detect version 1.0 of the Vector extension +// with HWCAP, if riscv_hwprobe were not available. However, the check cannot +// be added until the assembler supports the Vector instructions. +// +// Note the riscv_hwprobe syscall does not suffer from these ambiguities by design as all of the +// extensions it advertises support for are explicitly versioned.
