Hi, today, I've seen with pleasure that there's now an est module in the kernel.
Unfortunately, it seems not to support my Pentium-M 1.73GHz (Pentium M-740, 533MHz FSB): #kldload est Intel(R) Pentium(R) M processor 1.73GHz: Enhanced Speedstep not supported on this processor module_register_init: MOD_LOAD (est, df859b3f, 0) error 45 Please add support for my CPU type. This is, what cpuid tells me: SchlesisNB# cpuid eax in eax ebx ecx edx 00000000 00000002 756e6547 6c65746e 49656e69 00000001 000006d8 00000816 00000180 afe9fbff 00000002 02b3b001 000000f0 00000000 2c04307d 80000000 80000008 00000000 00000000 00000000 80000001 00000000 00000000 00000000 00000000 80000002 20202020 20202020 65746e49 2952286c 80000003 6e655020 6d756974 20295228 7270204d 80000004 7365636f 20726f73 33372e31 007a4847 80000005 00000000 00000000 00000000 00000000 80000006 00000000 00000000 08006040 00000000 80000007 00000000 00000000 00000000 00000000 80000008 00002020 00000000 00000000 00000000 Vendor ID: "GenuineIntel"; CPUID level 2 Intel-specific functions: Version 000006d8: Type 0 - Original OEM Family 6 - Pentium Pro Model 13 - Stepping 8 Reserved 0 Brand index: 22 [not in table] Extended brand string: " Intel(R) Pentium(R) M processor 1.73GHz" CLFLUSH instruction cache line size: 8 Feature flags afe9fbff: FPU Floating Point Unit VME Virtual 8086 Mode Enhancements DE Debugging Extensions PSE Page Size Extensions TSC Time Stamp Counter MSR Model Specific Registers PAE Physical Address Extension MCE Machine Check Exception CX8 COMPXCHG8B Instruction APIC On-chip Advanced Programmable Interrupt Controller present and enabled SEP Fast System Call MTRR Memory Type Range Registers PGE PTE Global Flag MCA Machine Check Architecture CMOV Conditional Move and Compare Instructions FGPAT Page Attribute Table CLFSH CFLUSH instruction DS Debug store ACPI Thermal Monitor and Clock Ctrl MMX MMX instruction set FXSR Fast FP/MMX Streaming SIMD Extensions save/restore SSE Streaming SIMD Extensions instruction set SSE2 SSE2 extensions SS Self Snoop TM Thermal monitor 31 reserved TLB and cache info: b0: unknown TLB/cache descriptor b3: unknown TLB/cache descriptor 02: Instruction TLB: 4MB pages, 4-way set assoc, 2 entries f0: unknown TLB/cache descriptor 7d: unknown TLB/cache descriptor 30: unknown TLB/cache descriptor 04: Data TLB: 4MB pages, 4-way set assoc, 8 entries 2c: unknown TLB/cache descriptor Thanks, Thomas
