3 RISC-V Hardware Probing Interface

6 The RISC-V hardware probing interface is based around a single syscall, which
18 The arguments are split into three groups: an array of key-value pairs, a CPU
19 set, and some flags. The key-value pairs are supplied with a count. Userspace
22 will be cleared to -1, and its value set to 0. The CPU set is defined by
23 CPU_SET(3). For value-like keys (eg. vendor/arch/impl), the returned value will
24 be only be valid if all CPUs in the given set have the same value. Otherwise -1
25 will be returned. For boolean-like keys, the value returned will be a logical
