Kernel driver i2c-sis96x |
|
======================== |
|
|
|
Replaces 2.4.x i2c-sis645 |
|
|
|
Supported adapters: |
|
|
|
* Silicon Integrated Systems Corp (SiS) |
|
|
|
Any combination of these host bridges: |
|
645, 645DX (aka 646), 648, 650, 651, 655, 735, 745, 746 |
|
|
|
and these south bridges: |
|
961, 962, 963(L) |

Description |
|
----------- |
|
|
|
This SMBus only driver is known to work on motherboards with the above |
|
named chipset combinations. The driver was developed without benefit of a |
|
proper datasheet from SiS. The SMBus registers are assumed compatible with |
|
those of the SiS630, although they are located in a completely different |
|
place. Thanks to Alexander Malysh <[email protected]> for providing the |
|
SiS630 datasheet (and driver). |
|
|
|
The command ``lspci`` as root should produce something like these lines:: |
|
|
|
00:00.0 Host bridge: Silicon Integrated Systems [SiS]: Unknown device 0645 |
|
00:02.0 ISA bridge: Silicon Integrated Systems [SiS] 85C503/5513 |
|
00:02.1 SMBus: Silicon Integrated Systems [SiS]: Unknown device 0016 |
|
|
|
or perhaps this:: |
|
|
|
00:00.0 Host bridge: Silicon Integrated Systems [SiS]: Unknown device 0645 |
|
00:02.0 ISA bridge: Silicon Integrated Systems [SiS]: Unknown device 0961 |
|
00:02.1 SMBus: Silicon Integrated Systems [SiS]: Unknown device 0016 |
|
|
|
(kernel versions later than 2.4.18 may fill in the "Unknown"s) |
|
|
|
If you can't see it please look on quirk_sis_96x_smbus |
|
(drivers/pci/quirks.c) (also if southbridge detection fails) |
|
|
|
I suspect that this driver could be made to work for the following SiS |
|
chipsets as well: 635, and 635T. If anyone owns a board with those chips |
|
AND is willing to risk crashing & burning an otherwise well-behaved kernel |
|
in the name of progress... please contact me at <[email protected]> or |
|
via the linux-i2c mailing list: <[email protected]>. Please send bug |
|
reports and/or success stories as well. |
|
|
|
|
|
TO DOs |
|
------ |
|
|
|
* The driver does not support SMBus block reads/writes; I may add them if a |
|
scenario is found where they're needed. |

Thank You |
