* ACPI: thinkpad-acpi: update brightness sysfs interface supportHenrique de Moraes Holschuh2007-04-25
| | | | | | | | | | | | Update the brightness sysfs interface (done through the backlight class) to be in line with the rest of the thinkpad-acpi driver. This renames the incorrect, un-obvious, and clash-prone name of "ibm" for the backlight device to a much more fitting and descriptive "thinkpad_screen". This is something I wanted to do for quite a while... Signed-off-by: Henrique de Moraes Holschuh <hmh@hmh.eng.br> Signed-off-by: Len Brown <len.brown@intel.com>

* ACPI: thinkpad-acpi: add a safety net for TPEC fan control modeHenrique de Moraes Holschuh2007-04-25
| | | | | | | | | | | | | | | | | The Linux ThinkPad community is not positive that all ThinkPads that do HFSP EC fan control do implement full-speed and auto modes, some of the earlier ones supporting HFSP might not. If the EC ignores the AUTO or FULL-SPEED bits, it will pay attention to the lower three bits that set the fan level. And as thinkpad-acpi was leaving these set to zero, it would stop(!) the fan, which is Not A Good Thing. So, as a safety net, we now make sure to also set the fan level part of the HFSP register to speed 7 for full-speed, and a minimum of speed 4 for auto mode.

* ACPI: thinkpad-acpi: add sysfs support to fan subdriverHenrique de Moraes Holschuh2007-04-25
| | | | | | | | | | | | | | | | | | Export sysfs attributes to monitor and control the internal thinkpad fan (some thinkpads have more than one fan, but thinkpad-acpi doesn't support the second fan yet). The sysfs interface follows the hwmon design guide for fan devices. Also, fix some stray "thermal" files in the fan procfs description that have been there forever, and officially support "full-speed" as the name for the PWM-disabled state of the fan controller to keep it in line with the hwmon interface. It is much better a name for that mode than the unobvious "disengaged" anyway. Change the procfs interface to also accept full-speed as a fan level, but still report it as disengaged for backwards compatibility.

* ACPI: thinkpad-acpi: add sysfs support to the thermal subdriverHenrique de Moraes Holschuh2007-04-25
| | | | | | | | | | | | | | | | | | Export thinkpad thermal sensors to sysfs, following the hwmon specification for thermal monitoring sensors. ThinkPad thermal monitoring is done by the EC. Sensors can show up or disappear at runtime when they are inside hotswappable hardware, such as batteries. Sensors that are not available return -ENXIO when accessed. Up to 16 thermal sensors are supported on new firmware (but nobody has reported a ThinkPad with more than 12 sensors so far), and 8 sensors are supported on older firmware. Thermal sensor mapping is model-specific. Precision varies, it is 1 degree Celcius on new ThinkPads, but higher on some older models.

* ACPI: ibm-acpi: rename driver to thinkpad-acpiHenrique de Moraes Holschuh2007-03-30
| | | | | | | | | | | | | | | | | | | | | Rename the ibm-acpi driver to thinkpad-acpi. ThinkPads are not even made by IBM anymore, so it is high time to rename the driver... The name thinkpad-acpi was used sometime ago by a thinkpad-specific hotkey driver by Erik Rigtorp, around the 2.6.8-2.6.10 time frame. The driver apparently never got merged into mainline (it did make some trips through -mm). ibm-acpi was merged soon after, making its debut in 2.6.10. The reuse of the thinkpad-acpi name shouldn't be a problem as far as user confusion goes, as Erik's thinkpad-acpi apparently didn't get widespread use in the Linux ThinkPad community and most hits for thinkpad-acpi in google point to ibm-acpi anyway. Erik, if you read this, please consider the reuse of the thinkpad-acpi name as a compliment to your effort to make ThinkPads more useful to all of us.

* [PATCH] clocksource: Fix thinko in watchdog selectionThomas Gleixner2007-03-25
| | | | | | | | | | | | | | | | | The watchdog implementation excludes low res / non continuous clocksources from being selected as a watchdog reference unintentionally. Allow using jiffies/PIT as a watchdog reference as long as no better clocksource is available. This is necessary to detect TSC breakage on systems, which have no pmtimer/hpet. The main goal of the initial patch (preventing to switch to highres/nohz when no reliable fallback clocksource is available) is still guaranteed by the checks in clocksource_watchdog().

* [PATCH] dynticks: fix hrtimer rounding error in next_timer_interruptThomas Gleixner2007-03-25
| | | | | | | | | | | | | | | | | | | | | | | | The rework of next_timer_interrupt() fixed the timer wheel bugs, but invented a rounding error versus the next hrtimer event. This is caused by the conversion of the hrtimer internal representation to relative jiffies. This causes bug #8100: http://bugzilla.kernel.org/show_bug.cgi?id=8100 next_timer_interrupt() returns "now" in such a case and causes the code in tick_nohz_stop_sched_tick() to trigger the timer softirq, which is bogus as no timer is due for expiry. This results in an endless context switching between idle and ksoftirqd until a timer is due for expiry. Modify the hrtimer evaluation so that, it returns now + 1, when the conversion results in a delta < 1 jiffie.
