Hello Lm-sensors team : This is LH Hsu, software coordinator of Winbond computer related product. I appreciate you contribution for Linux design and kind help for hardware monitor development of our staff. Chunhao works in mainland China. Currently I am in business trip in China. Most of time I work at Taiwan. The area of Taiwan is closed to mother board maker I can do my best to have cooperation. Your meaning is you need the data sheet., especially SMBus part. Some of mother board maker or chip set maker are not public that. I can not get all of data sheet or mother board information. I suggest you got the mother board and Winbond chip mounted Super IO, 78x or 79x). Please send me the mother board maker vendor, mother board model, south bridge brand , south bridge chipset no and your requirement. I can do my best to collect information. It is impossible for mother board maker to release chipset number of all model. I can consult mother board maker about Winbond product. Some information of mother board maker is confidential. If it is required for your development, you can let me know, too. I try to do. DZShen is the coordinator of Linux development. He is familiar with Linux design. Please send your requirement ,too.

Opps, I missed my subject. Sorry. Hello, > I can understand your feelings and complaint absolutely, I'm sorry for > the trouble and obstacles brought you.

I created some paper for your "responsible manager" staff. Please forward it to them. Needs of opensource software development model on fields of system monitoring ----------------------------------------------- Most of motherboard manufacturers do not support the hardware monitoring capabilities of their products in free operating systems (or simply other than Windows). Thus, open projects were created to build support of the hardware monitoring chips "on their own". On the Linux platform project lm-sensors created unified infrastructure and framework to support different hardware monitoring chips and busses. In mean time new chips or busses support is handled by members of lm-sensors project. They are working for free, or sometimes someone supports their work by donating the hardware, in many cases not the chip makers but frustrated third parties that are willing to support this project. Cooperation with manufactures was limited to evaluation board donations or datasheet support. We are glad that Winbond decided to work on support of new chips with us, directly supporting our project with new driver. However to enhance our future cooperation it is essential to understand specific needs of open source development. * Free access to documentation Our source code is not proprietary, under license conditions anyone can fix or modify the source code. Chip driver maintenance implies access to chip documentation. Without that future maintenance of driver is not possible. * Free access to SMBus host documentation Our drivers are build upon transport layer provided by other drivers for SMBus (System Management Bus). It is essential that documentation to this SMBus host chip is also accessible. We do not need whole southbridge documentation we just need to know the way how to speak with SMBUS host. Please try to convince some chipset makers about this, specially NVIDIA, SiS and ALI. Most of registers is done same way in all chipset following ACPI standart, but it is essential to know what is done differently. * Support from motherboard manufacturers This is very crucial and anticipatory point. There is no cooperation these days. When motherboard manufacturers follows recommended values of resistors nets, conversion formulas can be gained from datasheet. End users are happy that our project is supporting their workstations or company servers instead of "no support" from motherboard manufacturer. But from time to time motherboard maker decides to use other components resulting in unknown conversion formulas. Motherboard manufacturers do not want to disclose information about the formulas or simply do not respond. This is very strange behavior, we created our project to support different kind of hardware and indirectly we are supporting motherboard manufacturers products by our work. We can't understand that this simple thing is not understood. * Additional obstacles set by motherboard manufactures Some created proprietary monitoring interfaces or their own ASIC and they do not want to disclose documentation to this chips. Some are playing hide and seek. Infamous examples: Abit created their uGuru (in fact programmed Winbond IC), they do not want to disclose information even to "closed source" companies. Bad luck, we can only tell to growing Linux userbase - avoid them ASUS created their own proprietary ASIC chips, however their programming interface is very very close to Winbond so our driver was developed on "guesswork". We do not support new chips with no documentation today. Unfortunately we can't drop support for already supported ones even if it's a pain. ASUS is even more creative, they started to hide SMBUS host, later they start to hide "well known" monitoring chips, result is that we cannot help much with this to end users. Complaints to ASUS do not work. Summary ------- Please try to explain the motherboard companies that they have unique opportunity to have support of their monitoring chips in Linux with no additional cost to them, when they will communicate with us and provide documentation that is essential to support their motherboard. Please try to explain to chipset makers that we really need parts of documentation of their southbridge to be able to implement SMBUS host driver. We do not need full datasheet only small part of it. When it is not possible to disclose the chip documentation to public we would like to have a possibility to members of our project to have shared access to the documentation.
