2008-10-20Remove empty imacfb.c fileLinus Torvalds
Commit 7c08c9ae0c145807c0dae4a55f240fa3d4fd5262 ("efifb/imacfb consolidation + hardware support") claimed to remove imacfb entirely and merge its DMI table into the efifb driver. So far so good, but the diff actually ended up just generating an empty file instead of removing it. [ Technical reason: the patch header looked like diff -puN drivers/video/imacfb.c~efifb-imacfb-consolidation-hardware-support drivers/video/imacfb.c --- a/drivers/video/imacfb.c~efifb-imacfb-consolidation-hardware-support +++ a/drivers/video/imacfb.c @@ -1,376 +0,0 @@ which git will think is a truncation, not a delete.

2008-10-20x86: sysfs: kill owner field from attributeParag Warudkar
Tejun's commit 7b595756ec1f49e0049a9e01a1298d53a7faaa15 made sysfs attribute->owner unnecessary. But the field was left in the structure to ease the merge. It's been over a year since that change and it is now time to start killing attribute->owner along with its users - one arch at a time! This patch is attempt #1 to get rid of attribute->owner only for CONFIG_X86_64 or CONFIG_X86_32 . We will deal with other arches later on as and when possible - avr32 will be the next since that is something I can test. Compile (make allyesconfig / make allmodconfig / custom config) and boot tested. akpm: the idea is that we put the declaration of sttribute.owner inside `#ifndef CONFIG_X86'. But that proved to be too ambitious for now because new usages kept on turning up in subsystem trees.

Teach rtc-cmos about the second bank of registers found on most modern x86 systems, giving access to 128 bytes more NVRAM. This version only sees that extra NVRAM when both register banks are provided as part of *one* PNP resource. Since BIOS on some systems presents them using two IO resources, and nothing merges them, this can't always show all the NVRAM. (We're supposed to be able to use PNP id PNP0b01 too, but BIOS tables doesn't often seem to use that particular option.)

2008-10-20hwmon: applesmc: lighter wait mechanism, drastic improvementHenrik Rydberg
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.

2008-10-20hwmon: applesmc: prolong status waitHenrik Rydberg
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.

2008-10-20hwmon: applesmc: fix the 'wait status failed: c != 8' problemHenrik Rydberg
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.

2008-10-20hwmon: applesmc: specified number of bytes to read should match actualHenrik Rydberg
At one single place in the code, the specified number of bytes to read and the actual number of bytes read differ by one. This one-liner patch fixes that inconsistency.

2008-10-20hwmon/pc87360 separate alarm files: add therm-min/max/crit-alarmsJim Cromie
Adds therm-min/max/crit-alarm callbacks, sensor-device-attribute declarations, and refs to those new decls in the macro used to initialize the therm_group (of sysfs files) The thermistors use voltage channels to measure; so they don't have a fault-alarm, but unlike the other voltages, they do have an overtemp, which we call crit (by convention).

2008-10-20hwmon/pc87360 separate alarm files: define some constantsJim Cromie
Bring hwmon/pc87360 into agreement with Documentation/hwmon/sysfs-interface. Patchset adds separate limit alarms for voltages and temps, it also adds temp[123]_fault files. On my Soekris, temps 1,2 are unused/unconnected, so temp[123]_fault = 1,1,0 respectively. This agrees with /usr/bin/sensors, which has always shown them as OPEN. Temps 4,5,6 are thermistor based, and dont have a fault bit in their status register. This patch: 2 different kinds of constants added: - CHAN_ALM_* constants for (later) vin, temp alarm callbacks. - CHAN_* conversion constants, used in _init_device, partly for RW1C bits Signed-off-by: Jim Cromie <jim.cromie@gmail.com> Cc: Jean Delvare <khali@linux-fr.org> Cc: "Mark M.
