I'd had a conversation with one if Cavium's engineers years ago where he said that he wished FreeBSD implemented TLS this way, implying cavium has them.

The " Config3=" message generated from cpu_identify() say if the hardware supports it. Bit 14 will be on... #define MIPS_CONFIG3_ULR 0x00002000 /* UserLocal reg implemented */ -stacey.help
