I am a bit puzzled by the differnce with two X2 boards I have around here : FreeBSD 7.1-PRERELEASE #0: Tue Dec 2 20:09:28 ... CPU: AMD Athlon(tm) 64 X2 Dual Core Processor 6000+ (2992.52-MHz K8-class CPU) Origin = "AuthenticAMD" Id = 0x40f33 Stepping = 3 Features=0x178bfbff Features2=0x2001 AMD Features=0xea500800 AMD Features2=0x1f Cores per package: 2 ... cpu0: on acpi0 powernow0: on cpu0 cpu1: on acpi0 powernow1: on cpu1 FreeBSD 7.1-PRERELEASE #1: Mon Nov 17 14:40:26 ... CPU: AMD Turion(tm) 64 X2 Mobile Technology TL-62 (2109.70-MHz K8-class CPU) Origin = "AuthenticAMD" Id = 0x60f82 Stepping = 2 Features=0x178bfbff Features2=0x2001 AMD Features=0xea500800 AMD Features2=0x11f Cores per package: 2 ... cpu0: on acpi0 acpi_throttle0: on cpu0 powernow0: on cpu0 cpu1: on acpi0 acpi_throttle1: on cpu1 acpi_throttle1: failed to attach P_CNT device_attach: acpi_throttle1 attach returned 6 powernow1: on cpu1 whereas the Phenom says : CPU: AMD Phenom(tm) 9750 Quad-Core Processor (2410.66-MHz K8-class CPU) Origin = "AuthenticAMD" Id = 0x100f23 Stepping = 3 Features=0x178bfbff Features2=0x802009> AMD Features=0xee500800 AMD Features2=0x7ff,,,Prefetch,,> ... cpu0: on acpi0 acpi_throttle0: on cpu0 cpu1: on acpi0 cpu2: on acpi0 cpu3: on acpi0 my conclusion : acpi_throttle attaches a X4 (why not) and not at X2 (thought the Turion seems to detect it but fails to attach), powernow does not seem to attach to X4 ...
