| /* X Macro Definitions for Specification of RISC-V Arch Capabilities */ |
| |
| /* |
| * Each RISC-V capability ends up encoded as a single set bit in an array of |
| * words. When specifying a new capability, write a new RISCV_DEFINE_CAP |
| * statement, with an argument as the extension name in all-caps, |
| * second argument as the index in the array where the capability will be stored |
| * and third argument as the index of the bit to be used to encode the |
| * capability. |
| * |
| * The fourth and the fifth arguments are copied from linux header asm/hwprobe.h. |
| * Directly coping values instead of macro names comes from the fact |
| * that an old version may lack definition of some macro. |
| * When there is no hwprobe key/value pair for a capability, the key is set to -1 |
| * and the value is set to 0, as when the hwprobe syscall returns a key of -1, |
| * the value is set to 0 and the corresponding capability would not be enabled. |
| * |
| * RISCV_DEFINE_CAP(EXTENSION NAME, array index, bit index, hwprobe key, hwprobe value) */ |
