When the CPU SMT changes on the fly, send the message to pmfw to notify the SMT status changed. Changes in v3 1./ Because it is only required for Vangogh, move registering notifier to vangogh_ppt.c, then remove the patch 2, and the number of patches decreased to 2. Changes in v2: 1/. Embed the smt notifer callback into "struct smu_context" structure. 2/. Correct the PPSMC_Message_Count value. 3/. Improve several code styles and others.
