hwmon: (it87) Fix in7 on IT8720F

2010-08-02T17:29:23+00:00

commit 436cad2a41a40c6c32bd9152b63d17eeb1f7c99b upstream.

The IT8720F has no VIN7 pin, so VCCH should always be routed
internally to VIN7 with an internal divider. Curiously, there still
is a configuration bit to control this, which means it can be set
incorrectly. And even more curiously, many boards out there are
improperly configured, even though the IT8720F datasheet claims that
the internal routing of VCCH to VIN7 is the default setting. So we
force the internal routing in this case.

It turns out that all boards with the wrong setting are from Gigabyte,
so I suspect a BIOS bug. But it's easy enough to workaround in the
driver, so let's do it.

hwmon: (coretemp) Skip duplicate CPU entries

2010-08-02T17:29:23+00:00

commit d883b9f0977269d519469da72faec6a7f72cb489 upstream.

On hyper-threaded CPUs, each core appears twice in the CPU list. Skip
the second entry to avoid duplicate sensors.

hwmon: (coretemp) Properly label the sensors

2010-08-02T17:29:22+00:00

commit 3f4f09b4be35d38d6e2bf22c989443e65e70fc4c upstream.

Don't assume that CPU entry number and core ID always match. It
worked in the simple cases (single CPU, no HT) but fails on
multi-CPU systems.

hwmon: (k10temp) Do not blacklist known working CPU models

2010-08-02T17:29:22+00:00

commit eefc2d9e3d4f8820f2c128a0e44a23de28b1ed64 upstream.

When detecting AM2+ or AM3 socket with DDR2, only blacklist cores
which are known to exist in AM2+ format.

hwmon: (i5k_amb) Fix sysfs attribute for lockdep

2010-08-02T17:29:22+00:00

commit 0e6c7870856c7fb4ee054d28ac253b2d3d0c7e36 upstream.

i5k_amb.ko uses dynamically allocated memory (by kmalloc) for
attributes passed to sysfs. So, sysfs_attr_init() should be called
for working happy with lockdep.

hwmon: (k8temp) Fix temperature reporting for ASB1 processor revisions

2010-08-02T17:29:21+00:00

commit d535bad90dad4eb42ec6528043fcfb53627d4f89 upstream.

Reported temperature for ASB1 CPUs is too high.
Add ASB1 CPU revisions (these are also non-desktop variants) to the
list of CPUs for which the temperature fixup is not required.

Example: (from LENOVO ThinkPad Edge 13, 01972NG, system was idle)

  Current kernel reports

  $ sensors
  k8temp-pci-00c3
  Adapter: PCI adapter
  Core0 Temp:  +74.0 C
  Core0 Temp:  +70.0 C
  Core1 Temp:  +69.0 C
  Core1 Temp:  +70.0 C

  With this patch I have

  $ sensors
  k8temp-pci-00c3
  Adapter: PCI adapter
  Core0 Temp:  +54.0 C
  Core0 Temp:  +51.0 C
  Core1 Temp:  +48.0 C
  Core1 Temp:  +49.0 C

hwmon: (k8temp) Bypass core swapping on single-core processors

2010-08-02T17:29:21+00:00

commit cd4de21f7e65a8cd04860f5661b3c18648ee52a1 upstream.

Commit a2e066bba2aad6583e3ff648bf28339d6c9f0898 introduced core
swapping for CPU models 64 and later. I recently had a report about
a Sempron 3200+, model 95, for which this patch broke temperature
reading. It happens that this is a single-core processor, so the
effect of the swapping was to read a temperature value for a core
that didn't exist, leading to an incorrect value (-49 degrees C.)

Disabling core swapping on singe-core processors should fix this.

Additional comment from Andreas:

The BKDG says

  Thermal Sensor Core Select (ThermSenseCoreSel)-Bit 2. This bit
  selects the CPU whose temperature is reported in the CurTemp
  field. This bit only applies to dual core processors. For
  single core processors CPU0 Thermal Sensor is always selected.

k8temp_probe() correctly detected that SEL_CORE can't be used on single
core CPU. Thus k8temp did never update the temperature values stored
in temp[1][x] and -49 degrees was reported. For single core CPUs we
must use the values read into temp[0][x].

hwmon: (ltc4245) Read only one GPIO pin

2010-07-05T18:22:37+00:00

commit df16dd53c575d0cb9dbee20a3149927c862a9ff6 upstream.

Read only one of the GPIO pins as an analog voltage. The ADC can be
switched to a different GPIO pin at runtime, but this is not supported.

Previously, this driver would report the analog voltage of the currently
selected GPIO pin as all three GPIO voltages: in9_input, in10_input and
in11_input.

hp_accel: fix race in device removal

2010-05-12T00:33:42+00:00

The work queue has to be flushed after the device has been made
inaccessible.  The patch closes a window during which a work queue might
remain active after the device is removed and would then lead to ACPI
calls with undefined behavior.
