Delete. Most of the items are for kernel drivers, this information no longer
belongs there. The rest is hopefully implemented now. Next TODOs will be handled in trac. git-svn-id: http://lm-sensors.org/svn/lm-sensors/branches/lm-sensors-3.0.0@4866 7894878c-1315-0410-8ee3-d5d059ff63e0

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.
|
||||
|
||||
Driver Manual PWM Smart fan
|
||||
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.
|
||||
|
||||
Driver Manual PWM
|
||||
mtp008 standard
|
||||
smsc47m1 standard
|
||||
vt8231 standard
|
||||
w83781d (except 791d) standard
|
||||
|
||||
* 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.
|
||||
|
||||
* 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.
|
||||
|
||||
* 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
|
||||
|
||||
* Support 10-bit addresses. At this moment, they are supported nowhere, except
|
||||
in Simon Vogl's i2c modules.
|
||||
|
||||
* 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.
|
||||
|
||||
|
||||
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 }
|
||||
|
||||
* 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)
