Hi Hans,

At last here is a new version of the sensors config tool.


First of all many thanks for your continued work on this, it
is looking very good, so hopefully we will be able to soon
ship an lm_sensors with working auto-configuration of
(known) motherboards.

Now we have a shell script doing the auto installation stuff. See
install.sh patch 2/2. Further I removed this part of the python
script.


The shell script looks good, nice and simple, great!

As discussed, the config files from lm-sensors.org are fetched to
vendor specific directories and links are made in the root config
directory.

Great!


This looks like this:

Also looks good :)

The fetching tool parses headers like:

# board_vendor: Fujitsu
# board_name: D2312A1
# board_version: 1.0

Board version is optional. The block can appear mutliple times.

# board_vendor: Fujitsu
# board_name: D2312A1

# board_vendor: Fujitsu
# board_name: D23122A

# board_vendor: Fujitsu
# board_name: D2312C1

# board_vendor: Fujitsu
# board_name: D2312C2

The same rules apply to the product headers.

# sys_vendor: Fujitsu
# product_name: D2312D2
# product_version: 2.0

Next task is the module auto loading stuff but first, what about this
here?


I think this all looks very good! I think the module auto loading
is the only remaining item to do before this could actually become
production ready (although we will want Jean's input on this too).

The module autoloading requires 2 questions to be answered:

1) How do we store which modules are needed into the configuration
   files on the wiki

2) How / where / what will these modules get loaded ? Currently we
   have lines like these in /etc/sysconfig/lm_sensors:

# The format of this file is a shell script that simply defines variables:
# HWMON_MODULES for hardware monitoring driver modules, and optionally
# BUS_MODULES for any required bus driver module (for example for I2C or SPI).

HWMON_MODULES="it87"

# For compatibility reasons, modules are also listed individually as variables
#    MODULE_0, MODULE_1, MODULE_2, etc.
# You should use BUS_MODULES and HWMON_MODULES instead if possible.

MODULE_0=it87


We could add new "keys" to this file, say:
AUTOMOBO_HWMON_MODULES
AUTOMOBO_BUS_MODULES

And modify the lm_sensors initscript to recognize these too, or thinking more
about this, as we need the script which does the copying of the config file
to /etc/sensors.d/automobo.conf, to extract the modules for us anyways (to
insert them into /etc/sysconfig/lm_sensors for example). We might just as
well make that script load the modules directly.

This also solves a problem with the HWMON_MODULES="it87" syntax, namely
that it does not allow specifying module parameters.

Jean, could we have your input on this ?

Thanks & Regards,

Hans
