Hello regards 1. I am going to connect Abit for getting the SMBus register definition of Ali south bridge . Any conclusion I will send you ASAP. 2. I got the SMM. 792 provides to assert SMI for urgent case, But the SMI is specified by chipset and there is no standard for SMI service routine vector. Mother board BIOS engineer cover that. I have no enough information to answer it, BR LH Hsu -----Original Message----- From: Rudolf Marek [mailto:R.Marek at sh.cvut.cz] Sent: Monday, March 21, 2005 11:51 PM To: PI10 LHHsu Cc: PI14 HUANG0; sensors at Stimpy.netroedge.com; mochel at digitalimplant.org; PI14 DZSHEN; PI13 CFLi Subject: RE: We will port w83792d.c to linux-2.6 Hello, > > If so what are the algorithms when bus/controller is not ready? > Ans : I can not get your real meaning of SMM.

There is always good for us to have datasheets but I dont know if we can get more. Patrick already told us what we wanted to know but perhaps he could not give us his own. Maybe there is some problem with some agreements. SMM mode is a microprocesor mode similar to Protected Mode or Real Mode, Processsor can fall into this mode with SMI interrupt. Then special code will be executed and after finishing procesor will return back to its original state. Simply you can imagine SMM mode as some interupt service routine that is independent of operating system. Typically this SMM routine does USB legacy emulation and also handles overtemperature events etc. If their code is working with SMBus controller than it might be the issue of our problem. Memory used while in SMM mode is that RAM memory that is hidden bellow VIDEO RAM. (between 640Kb-1M) chipset is handling the memory map swapping. So my question is: are routine implemented in BIOS SMM code part using the SMBus controller? If so how they handle the "bus free/not free" also how often is SMM code executed. I hope this helps regards Rudolf ===========================================================================================The privileged confidential information contained in this email is intended for use only by the addressees as indicated by the original author of this email.
