1. Initialize Pstates global parameters (G_proc_fmax, G_proc_fmin, G_khz_per_pstate and G_proc_pmin from the OCC Pstate Parameter Block) 2. When frequency config data packet is received and OCC is NOT already in Active state: Send IPC command to PGPE to set pState clips to be wide open from min frequency to turbo First verify min/max frequency from TMGT is within what PGPE allows saved in G_proc_fmax and G_proc_fmin if not within bounds trace and clip to G_proc_fmax/fmin) 3. Transition to active state: Send IPC command to PGPE to start pState protocol (give correct data for OCC vs OPAL in control of Pstates) and if OPAL system update OPAL shared memory with Pstate information. 4. amec_slv_freq_smh(): Send IPC command to PGPE to set requested pState (PowerVM) or set clips (OPAL). 5. Address all the TODO/TEMP/#if 0 in amec_freq.c either remove or add RTC# for when it will be addressed Change-Id: Ic323321b8c66945732a6b7345ad85d6f41a62edd RTC: 130201 Reviewed-on: http://ralgit01.raleigh.ibm.com/gerrit1/33704 Tested-by: FSP CI Jenkins <fsp-CI-jenkins+hostboot@us.ibm.com> Reviewed-by: Martha Broyles <mbroyles@us.ibm.com> Reviewed-by: Andres A.
