Systems with NCT6775F reported temperature sensor labels for systems with
NCT6776F. This patch fixes the problem.Signed-off-by: Guenter Roeck
-
NCT6776F and NCT6775F support debouncing the fan RPM signal. This can
help improve the stability of th RPM signal for some fans (Arctic cooling
fans for example).
This patch adds a module parameter fan_debounce, which when set to 1 enables
debounce for all fans that the chip supports.Signed-off-by: Ian Dobson
Signed-off-by: Guenter Roeck -
Since the fan speed value can be above 0xff, we can no longer use
that value to determine if the fan speed reading is valid. This
makes it difficult to manipulate the stored fan speed register value.If we store rpm instead of the fan speed register value, we do not
need to correct it if the fan divisor value is changed, and the above
mentioned problem no longer exists.Signed-off-by: Guenter Roeck

Some of the chips supported by this driver have 13 bit or 16 bit fan count
registers. This patch improves support for those registers, specifically for
NCT6775F. With the changes in this patch, fan speed is reported correctly even
if the fan divider is set to a low value, which results in a fan speed reading
above 0xff.With this patch, the width of fan count registers is no longer used to determine
if the chip has fan divider register(s) or not. A dedicated flag is used instead
to determine if this is the case.Signed-off-by: Guenter Roeck

For newer chips, several registers are banked and thus need to be 16 bit.
Also, register addresses change.To prepare for those chips, convert affected register arrays to 16 bit,
and change access to those registers to array pointers in struct w83627ehf_data.Signed-off-by: Guenter Roeck

Add control of fan minimum turn-on output levels, decoupling it from the
fan turn-off output level. Add control of rate of change of fan output
level. These in turn allow lower turn-off rotor speed and smoother
transitions for better thermal and acoustic control authority. Add
support for constant fan speed and proportional-response operations modes.[akpm@linux-foundation.org: coding-style fixes]

Add support for the new incarnation of the Winbond/Nuvoton W83627DHG
chip known as W83627DHG-P. It is basically the same as the original
W83627DHG with an additional automatic can speed control mode (not
supported by the driver yet.)Signed-off-by: Jean Delvare

The pin for in6 and temp3 is shared on the W83667HG, so only one of

Add initial support for the Nuvoton W83667HG chip to the w83627ehf
driver. It has been tested on ASUS P5QL PRO by Gong Jun.At the moment there is still a usability issue which is that only in6
or temp3 can be present on the W83667HG, so the driver shouldn't
expose both. This will be addressed later.Signed-off-by: Gong Jun

Check for ACPI resource conflicts in hwmon drivers. I've included
all Super-I/O and PCI drivers.I've voluntarily left out:
* Vendor-specific drivers: if they conflicted on any system, this would
pretty much mean that they conflict on all systems, and we would know
by now.
* Legacy ISA drivers (lm78 and w83781d): they only support chips found
on old designs were ACPI either wasn't supported or didn't deal with
thermal management.
* Drivers accessing the I/O resources indirectly (e.g. through SMBus):
the checks are already done where they belong, i.e. in the bus drivers.Signed-off-by: Jean Delvare

While the W83627EHF/EHG has only 6 VID pins, the W83627DHG has 8 VID
pins, to support VRD 11.0. Add support for this.Signed-off-by: Jean Delvare
Signed-off-by: Mark M. Hoffman -
While it is possible to force SMBus-based hardware monitoring chip
drivers to drive a not officially supported device, we do not have this
possibility for Super-I/O-based drivers. That's unfortunate because
sometimes newer chips are fully compatible and just forcing the driver
to load would work. Instead of that we have to tell the users to
recompile the kernel driver, which isn't an easy task for everyone.So, I propose that we add a module parameter to all Super-I/O based
hardware monitoring drivers, letting advanced users force the driver
to load on their machine. The user has to provide the device ID of a
supposedly compatible device. This requires looking at the source code or
a datasheet, so I am confident that users can't randomly force a driver
without knowing what they are doing. Thus this should be relatively safe.As you can see from the code, the implementation is pretty simple and
unintrusive.Signed-off-by: Jean Delvare

The VID input level change has been reported to cause trouble. Be more
careful in this respect:
* Only change the level on the W83627EHF/EHG. The W83627DHG is more
complex in this respect.
* Don't change the level if the VID pins are in output mode.
* Only set the level to TTL if VRM 9.x is used.Signed-off-by: Jean Delvare

Don't assume that the default bank is 0. For one thing, we don't even
set it to 0 when the driver is loaded, so the initial state might be
different. For another, something (say, the BIOS) might access the chip
and leave with the bank set to something different, so assuming that
the bank value is 0 is not safe.Signed-off-by: Jean Delvare

* I have experimental evidence that the W83627EHG needs more than 1
second to refresh all the measured values. Increase the caching time to
1.5 second.
* When changing a fan clock divider, the corresponding fan speed
measurement register is no longer valid, until the next time the chip
will refresh it. One way to fix this is to pretend that the cache is
still valid for one more period (1.5 second.)Signed-off-by: Jean Delvare

If the Super-I/O device is disabled, it is likely the BIOS has a good
reason for leaving it disabled, so give a warning when enabling it --
it's not likely to be wired correctly or be able to give good data.Also, if the Super-I/O device is configured with an address of 0, the
driver refuses to initialize it.Signed-off-by: David Hubbard
