ACPI tools 1.3 (Announce)

Yes, CPUSPD is certainly extremely interresting piece of software. Unfortunately, we do not have the source for the last version (for 2.2), ve have only for 2.0.
The throttling is coded in throttle.asm but inside are few strange things.
At first - there is commented out the jump inside ".searchDSDT" function so the ACPI/AML code is never analysed. The Processor_block (P_BLK) is extracted from FACP table which is absolutely incorrect.

Also, CPUSPD heavily uses model specific registers and ports which is outside the scope of my utility ACPI tools.
