Strangly enough, both these devices use a high byte, low byte order for word-sized reads and writes. The SMBus documentation specifies the reverse (low, high) order, though. If all devices use the high,low order, we should change this in smbus.c. git-svn-id: http://lm-sensors.org/svn/lm-sensors/trunk@64 7894878c-1315-0410-8ee3-d5d059ff63e0

Many, many things. Most notably:
|
|
|
|
* Check whether the FAN count divisors in the lm78 module are correct
|
|
(probably not!); correct gl518sm changed-fan_div_but_did_not_update_fans
|
|
* Wouldn't it be better to display all natural voltages for the LM78 chip,
|
|
and do *all* conversions through a user program?
|
|
* kmalloc with GFP_KERNEL can cause a context switch! Check whether this is
|
|
safe everywhere it is used.
|
|
* Support 10-bit addresses. At this moment, they are supported nowhere, except
|
|
in Simon Vogl's i2c modules.
|
|
* Change the i2c modules to keep the namespace clean (EXPORT_SYMBOL does not
|
|
work for us; many static declarations need to be added; better ask Simon
|
|
Vogl first)
|
|
* Make it SMP-safe: there are no spinlocks yet. They are needed at many
|
|
places, probably (everywhere where global vars are accessed). This must be
|
|
done for the i2c modules, too.
|
|
* Make lm78.c detect 'double hits', (same chip connected to both SMBus and
|
|
ISA).
|
|
* Better lm78/lm75 detection; insmod-time paramters to set addresses
|
|
(difficult, because of all i2c busses!).
|
|
* Registrate which i2c addresses are used (a la ISA) for each adapter.
|
|
* Rename i2c-proc.c to i2c-user.c, and extend it with /dev entries;
|
|
or, create a better i2c-dev.c, that understands SMBus commands.
|
|
* Write all other drivers
|
|
* How to make drivers detect thing *not*; for example, if a Winbond is
|
|
present, the LM75 driver should not try to access its simulated
|
|
LM75 chips (in this case, simply disable them - but what if the LM75
|
|
driver was loaded first?).
|
|
* Write a userland-library for SMBus/i2c access (through the /dev interface)
|
|
* Write a userland detection program for busses (clients are less important;
|
|
but perhaps needed too).
