* hwmon: (applesmc) Correct sysfs fan error handlingHenrik Rydberg2010-05-111-36/+25
| | | | | | | | | | The current code will not remove the sysfs files for fan numbers three and up. Also, upon exit, fans one and two are removed regardless of their existence. This patch cleans up the sysfs error handling for the fans. Signed-off-by: Henrik Rydberg <rydberg@euromail.se> Signed-off-by: Jean Delvare <khali@linux-fr.org>

* hwmon: applesmc: restore accelerometer and keyboard backlight on resumeHenrik Rydberg2009-09-221-12/+26
| | | | | | | | | | | | | | On resume from suspend, the driver currently resets the logical state as if it was brought up from halt. This patch uses the dev_pm_ops.resume/restore methods to synchronize the hardware with the memorized logical state, in effect bringing back the accelerometer and backlight to the state prior to suspend. Works for both suspend to ram and hibernation. The patch has zero effect on the running state.

* hwmon: applesmc: fix light sensor readings on newer MacBooksAlex Murray2009-01-151-0/+5
| | | | | | | | | | | | | | | | | | | | | The light sensors ALV0 and ALV1 on newer MacBooks (early 2008 and later) changed to report 10 bytes instead the earlier 6, and the sensor encoding subsequently changed. As a result, the reported light sensors readings are much too low. Via experiments leading up to this patch, it seems only the ALV0 is reporting data, and the most useful value therein is a 10-bit big-endian value at offset 6. This suggests that a new protocol was added as a backward-compatible replacement on top of the old one. This patch makes applesmc report the improved light sensor reading for the new machines, on a scale in conformance with earlier ones.

* hwmon: applesmc: lighter wait mechanism, drastic improvementHenrik Rydberg2008-10-201-10/+12
| | | | | | | | | | | | | | | | | | | The read fail ratio is sensitive to the delay between the first byte written and the first byte read; apparently the sensors cannot be rushed. Increasing the minimum wait time, without changing the total wait time, improves the fail ratio from a 8% chance that any of the sensors fails in one read, down to 0.4%, on a Macbook Air. On a Macbook Pro 3,1, the effect is even more apparent. By reducing the number of status polls, the ratio is further improved to below 0.1%. Finally, increasing the total wait time brings the fail ratio down to virtually zero.

* hwmon: applesmc: prolong status waitHenrik Rydberg2008-10-201-2/+2
| | | | | | | | | | | | | | | | | The time to wait for a status change while reading or writing to the SMC ports is a balance between read reliability and system performance. The current setting yields rougly three errors in a thousand when simultaneously reading three different temperature values on a Macbook Air. This patch increases the setting to a value yielding roughly one error in ten thousand, with no noticable system performance degradation.

* hwmon: applesmc: fix the 'wait status failed: c != 8' problemHenrik Rydberg2008-10-201-8/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | On many Macbooks since mid 2007, the Pro, C2D and Air models, applesmc fails to read some or all SMC ports. This problem has various effects, such as flooded logfiles, malfunctioning temperature sensors, accelerometers failing to initialize, and difficulties getting backlight functionality to work properly. The root of the problem seems to be the command protocol. The current code sends out a command byte, then repeatedly polls for an ack before continuing to send or recieve data. From experiments leading to this patch, it seems the command protocol never quite worked or changed so that one now sends a command byte, waits a little bit, polls for an ack, and if it fails, repeats the whole thing by sending the command byte again. This patch implements a send_command function according to the new interpretation of the protocol, and should work also for earlier models.

For now manually tweaking the fans prevents the sudden shutdown for me. cd /sys/devices/platform/applesmc.768 for x in fan{1,2,3,4}; do echo 1 > ${x}_manual echo 1285 > ${x}_output done Two sensors are 0, while four are 129 °C, those might be removed again, later.

|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Three main sets of changes: 1) dmi_get_system_info() return value should have been marked const, since callers should not be changing that data. 2) const-ify DMI internals, since DMI firmware tables should, whenever possible, be marked const to ensure we never ever write to that data area. 3) const-ify DMI API, to enable marking tables const where possible in low-level drivers. And if we're really lucky, this might enable some additional optimizations on the part of the compiler. The bulk of the changes are #2 and #3, which are interrelated. #1 could have been a separate patch, but it was so small compared to the others, it was easier to roll it into this changeset.
