14 | Description | ||
15 | ----------- | ||
16 | |||
17 | This SMBus only driver is known to work on motherboards with the above | ||
18 | named chipset combinations. The driver was developed without benefit of a | ||
19 | proper datasheet from SiS. The SMBus registers are assumed compatible with | ||
20 | those of the SiS630, although they are located in a completely different | ||
21 | place. Thanks to Alexander Malysh <amalysh@web.de> for providing the | ||
22 | SiS630 datasheet (and driver). | ||
23 | |||
24 | The command "lspci" as root should produce something like these lines: | ||
25 | |||
26 | 00:00.0 Host bridge: Silicon Integrated Systems [SiS]: Unknown device 0645 | ||
27 | 00:02.0 ISA bridge: Silicon Integrated Systems [SiS] 85C503/5513 | ||
28 | 00:02.1 SMBus: Silicon Integrated Systems [SiS]: Unknown device 0016 | ||
29 | |||
30 | or perhaps this... | ||
31 | |||
32 | 00:00.0 Host bridge: Silicon Integrated Systems [SiS]: Unknown device 0645 | ||
33 | 00:02.0 ISA bridge: Silicon Integrated Systems [SiS]: Unknown device 0961 | ||
34 | 00:02.1 SMBus: Silicon Integrated Systems [SiS]: Unknown device 0016 | ||
35 | |||
36 | (kernel versions later than 2.4.18 may fill in the "Unknown"s) | ||
37 | |||
38 | If you cant see it please look on quirk_sis_96x_smbus | ||
39 | (drivers/pci/quirks.c) (also if southbridge detection fails) | ||
40 | |||
41 | I suspect that this driver could be made to work for the following SiS | ||
42 | chipsets as well: 635, and 635T. If anyone owns a board with those chips | ||
43 | AND is willing to risk crashing & burning an otherwise well-behaved kernel | ||
44 | in the name of progress... please contact me at <mhoffman@lightlink.com> or | ||
45 | via the project's mailing list: <sensors@stimpy.netroedge.com>. Please | ||
46 | send bug reports and/or success stories as well. | ||
47 | |||
48 | |||
49 | TO DOs | ||
50 | ------ | ||
51 | |||
52 | * The driver does not support SMBus block reads/writes; I may add them if a | ||
53 | scenario is found where they're needed. | ||
54 | |||
55 | |||
56 | Thank You | ||
