* | revert "x86, serial: convert legacy COM ports to platform devices"Andrew Morton2007-07-31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Revert 7e92b4fc345f5b6f57585fbe5ffdb0f24d7c9b26. It broke Sébastien Dugué's machine and Jeff said (persuasively) This seems like it will break decades-long-working stuff, in favor of breaking new ground in our favorite area, "trusting the BIOS." It's just not worth it for serial ports, IMO. Serial ports are something that just shouldn't break at this late stage in the game. My new Intel platform boxes don't even have serial ports, so I question the value of messing with serial port probing even more... because... just wait a year, and your box won't have a serial port either! :) I certainly don't object to the use of platform devices (or isa_driver), but the probe change seems questionable. That's sorta analagous to rewriting the floppy driver probe routine. Sure you could do it... but why risk all that damage and go through debugging all over again? It seems clear from this report that we cannot, should not, trust BIOS for something (a) so simple and (b) that has been working for over a decade. Much discussion ensued and we've decided to have another go at all of this.

Fortunately, the old CMOS NVRAM interface works just fine in such BIOSes. Add a module parameter that allows the user to select which strategy to use for brightness control: EC, NVRAM, or both. By default, do both (which is the way thinkpad-acpi used to work until now) on IBM ThinkPads, and use NVRAM only on Lenovo ThinkPads.

Hot keys that have a valid keycode mapping are reported through the input layer if the input device is open. Otherwise, they will be reported as ACPI events, as they were before. Scan codes are reported (using EV_MSC MSC_SCAN events) along with EV_KEY KEY_UNKNOWN events. For backwards compatibility purposes, hot keys that used to be reported through ACPI events are not mapped to anything meaningful by default. Userspace is supposed to remap them if it wants to use the input device for hot key reporting. This patch is based on a patch by Richard Hughes <hughsient@gmail.com>.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some ThinkPad models, notably the T60 and X60, have a slider switch to enable and disable the radios. The switch has the capability of force-disabling the radios in hardware on most models, and it is supposed to affect all radios (WLAN, WWAN, BlueTooth). Export the switch state as a sysfs attribute, on ThinkPads where it is available. Thanks to Henning Schild for asking for this feature, and for tracking down the EC register that holds the radio switch state.

| * | ACPI: thinkpad-acpi: export hotkey maximum masksHenrique de Moraes Holschuh2007-07-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The firmware knows how many hot keys it supports, so export this information in a sysfs attribute. And the driver knows which keys are always handled by the firmware in all known ThinkPad models too, so export this information as well in a sysfs attribute. Unless you know which events need to be handled in a passive way, do *not* enable hotkeys that are always handled by the firmware.

| * | ACPI: thinkpad-acpi: enable more hotkeysHenrique de Moraes Holschuh2007-07-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Revise ACPI HKEY functionality to better interface with the firmware, and enable up to 32 regular hotkeys, instead of just 16 of them. Ouch. This takes care of most keys one used to have to do CMOS NVRAM polling on, and should drop the need for tpb, thinkpad-keys, and other such 5Hz NVRAM polling power vampires on most modern ThinkPads ;-) And, just to add insult to injury, this was sort of working since forever through the procfs interface, but nobody noticed or tried an echo 0xffffffff > /proc/acpi/ibm/hotkey and told me it would generate weird events. ARGH! Thanks to Richard Hughes for kicking off the work that ended up with this discovery, and to Matthew Garret for calling my attention to the fact that newer ThinkPads were indeed generating ACPI GPEs when such hot keys were pressed.
