README.directories contains a description of the directories I created; read it if you have questions about them. doc/design is the design document I sent before through email. doc/useful_addresses.html contains links to I2C, SMBus and sensors information. Note that we may have to change minor i2c things, like Makefiles; this is why I put it in the archive too (we should, of course, send important changes to Simon Vogl). git-svn-id: http://lm-sensors.org/svn/lm-sensors/trunk@3 7894878c-1315-0410-8ee3-d5d059ff63e0

README for bit-mb.c and hw-monitor.c
|
|
September 23, 1998. Kyösti Mälkki
|
|
|
|
The questions you would probably want to ask
|
|
about bit-mb and hw-monitor, here are the answers.
|
|
|
|
What are bit-mb.c and hw-monitor.c?
|
|
|
|
Both are new modules for Simon G. Vogl's i2c-driver for Linux:
|
|
|
|
Bit-mb gives you access to motherboard's SMBus (or i2c -bus).
|
|
You should have VIA VT82C586B South Bridge, and this is verified on
|
|
module-load. On some motherboards, you must enable USB -support in BIOS-setup
|
|
to make it active, check this with pciutils or in /proc/pci.
|
|
NOTE: Accessing wrong registers on PCI-chipset is likely to lock your
|
|
computer. If your hardware goes BOOOMMM, don't blame me.
|
|
|
|
Hw-monitor is an i2c-driver for GL518SM (by Genesys Logic) chip, used in my
|
|
cpu fan (FAN78, EISCA-compatible). This gives you /proc/temperature to show
|
|
your cpu temperature. It is not tested with FAN79 (GL520SM), I will get the
|
|
datasheet for that in a few days.
|
|
|
|
|
|
Problems?
|
|
|
|
This is not near alpha-level, but it works with my FIC-VA503+.
|
|
There is no quarantee your motherboard manufacturer has used the VIA
|
|
recommended pins for i2c-lines... With my FIC, they have.
|
|
|
|
For error reports, turn i2c-debugging on. Check Simon's sourcecode
|
|
files for how to do that.
|
|
|
|
Please report any success or failure with possible logfiles to me:
