Hello,
Following patch (fidvid.patch) adds support for FID/VID changes messages. Upon incoming SMAF message from CPU (C3 or FID/VID change), the SB will assert SLP# which is connected to LDTSTOP_L on K8 CPUs. Question is for how long. Imho for 100us. Which is more than plenty (2us required) I will try to justify this once I know what bios to set in SB.

Second patch just gives an example what needs to be in DSDT to make it actually work. Usually this part is stored in secondary DSDT table (SSDT), which is build in runtime in BIOS. The values are computed for the CPU used in the system and cannon be static. I dont know how to do the computations yet.
