As far as I know, all QED processors have the "wait" instruction. All the 0x2??? processor ID values are QED processors. Here are the current values: #define C0_IMP_NEVADA 0x28 #define C0_IMP_RM7000 0x27 #define C0_IMP_MAGIC 0x25 #define C0_IMP_SONIC 0x24 #define C0_IMP_R5000 0x23 #define C0_IMP_R4650 0x22 #define C0_IMP_R4700 0x21 #define C0_IMP_R4600 0x20 I don't know which processors are SONIC, MAGIC, or NEVADA, but I think NEVADA is the new RM5260 (a low-cost R5000).
