LM-Sensors TODO list

I2C CODE CHANGES
|
|
================
|
|
|
|
See TODO in the i2c package.
|
|
|
|
|
|
KERNEL MODULES
|
|
==============
|
|
|
|
* Harmonize 'smart fan' support.
|
|
The following drivers support pwm. The ones that support
|
|
automatic or smart fan support are identified.
|
|
We have a /proc standard for manual PWM support that allows
|
|
for /proc based applications like pwmconfig and fancontrol
|
|
in our package.
|
|
Without a /proc standard for smart fan support such applications
|
|
are much more difficult.

adm1026 standard not supported
|
|
asb100 standard ??
|
|
it87 non-std yes
|
|
lm85 standard yes
|
|
vt1211 doesn't work not supported
|
|
w83627hf standard not supported
|
|
w83781d standard not supported (791 only)
|
|
|
|
The following drivers are for chips that have manual PWM only.

|
* Assistance on how to fix module refcounting is welcome.
|
|
To my understanding, it does not handle client->adapter->owner
|
|
correctly now, and it is possible to rmmod adapter while one of its
|
|
clients is in use.
|
|
|
|
* "uninstall" Makefile target.
|
|
|
|
* mkpatch. Trace back Configure changes from 2.5 tree and
|
|
have it make clean diffs.
|
|
Applies to both i2c and sensors.
|
|
|
|
* ACPI and SMBus host
|
|
- ACPI subsystem may access SMBus host too. Locks?
|
|
- On my ancient board using i2c-via, suspend and power switch status
|
|
seems to be in the same register with SCL and SDA.
|
|
|
|
* Suspend-to-disk, losing Vcc
|
|
- Reset i2c client to avoid alarms and SCI interrupts. Currently
|
|
sensors do not create interrupt with alarms.
|
|
|
|
* Return from suspend
|
|
- Reinitialize i2c client.
|
|
|
|
* Handle -1 returns from i2c layer rather than just delivering 0xFF to
|
|
/proc and libsensors; report errors through /proc 'alarms' or
|
|
new 'fail' entry? See adm1021 for a partial example.
|
|
|
|
* Add string function in sensors.o
|
|
* ALL: cleanup_module is void; check also that cleaning up is done
|
|
properly, now we know that the module will be unloaded whatever we
|
|
do.
|
|
* ALL chip drivers: add a readonly insmod option so we don't cause APM/ACPI
|
|
to go insane.
|
|
* gl518sm: using iterate==2 causes a tread to be started. this thread remains
|
|
even after setting iterate==1 and/or removing the gl518sm module
|
|
<koenig@uranus.tat.physik.uni-tuebingen.de>
|
|
* LM78 detection: Tom Webster has proven that the reset bit in the
|
|
id register can be one (strange!)
|
|
* maxilife.c: Introduce new insmod variables
|
|
* maxilife.c: Round REG_TO_VID correctly
|
|
* icspll.c: Rewrite. The current implementation simply can't work at all.
|
|
It needs i2c-level access (too bad for SMBus-only adapters).
|
|
* w83781d: Some features are still unsupported for the W8378[23].
|
|
Also, alarms seem to give strange results
|
|
sometimes, and there are some other minor problems, as indicated by
|
|
Jonathan Bradshaw <jonathan@NrgUp.Com>
|
|
* Support 10-bit addresses. At this moment, they are supported nowhere, except
|
|
in Simon Vogl's i2c modules.
|
|
* Better general locking, or at least a once-over to check no race-conditions
|
|
remain. This is part of the SMP-safeness, and can better be done at once.
|
|
* adm9240: check whether the current voltage computations are correct.
|
|
Probably not, as they are different from the datasheet specifications.
|
|
Also check for the supported dallas chip.
|
|
* lm80: Check how OS alarms work. At page 17 of the sheet, it tells
|
|
something completely different from the description at page 25.
|
|
* gl518sm: Assume that new values are close to old values, so start with
|
|
trying to use a small range near the old values (already partially done)
|
|
* lm77: Add detection in lm75.c and sensors-detect to distinguish from
|
|
an lm75. Add support for the two new registers.
|
|
* Add MTP006F chip: http://www.myson.com/Pcd/MTP006/Mtp006.pdf
|
|
gfiala@s.netic.de (Guido Fiala) has one on his mainboard
|

|
LIBRARY
|
|
=======
|
|
|
|
* Easier use of /proc and libsensors without knowing the chip type
|
|
At the moment a programmer wishing to use the lm_sensors package needs to know
|
|
what chips are supported and needs to add all those chips into his package.
|
|
If you were to add a field or function to your structures to the effect of
|
|
sensor-function a programmer could use the package a lot more simply.
|
|
For values you could do something like -
|
|
enum sensor-type { volt, fan, temp, volt_min, volt_max, fan_div, fan_min,
|
|
temp_over, temp_hyst }
|
|
|
|
* reload does not work (Bison/Flex problem?).
|
|
* Some library routines are pretty inefficient right now.
|
|
* Library should be split in more separate files, for better linking
|
|
behaviour.
|
|
* Some adm9240 labels start with a digit; change this, it leads to confusing
|
|
syntax in the conf file (they have to be quoted)
|
|
|
|
|
|
PROGRAMS
|
|
========
|
|
|
|
* Sensors program needs to print a + before lm75 temperatures
|
|
|
|
|
|
OTHERS
|
|
======
|
|
|
|
* Examine watchdog-4.3 or later of meskes@debian.org (Michael Meskes)
