2007-12-13ACPI: thinkpad-acpi: fix lenovo keymap for brightnessHenrique de Moraes Holschuh
Starting in 2.6.23... Several reports from X60 users complained that the default Lenovo keymap issuing EV_KEY KEY_BRIGHTNESS_UP/DOWN input events caused major issues when the proper brightness support through ACPI video.c was loaded. Therefore, remove the generation of these events by default, which is the right thing for T60, X60, R60, T61, X61 and R61 with their latest BIOSes. Distros that want to misuse these events into OSD reporting (which requires an ugly hack from hell in HAL) are welcome to set up the key map they need through HAL. That way, we don't break everyone else's systems. Signed-off-by: Henrique de Moraes Holschuh <hmh@hmh.eng.br> Signed-off-by: Len Brown <len.brown@intel.com>

2007-11-19ACPI: thinkpad-acpi: fix oops when a module parameter has no valueHenrique de Moraes Holschuh
set_ibm_param() could OOPS with a NULL pointer derreference if one did not give any values for a module parameter it handles. This would, of course, cause all sort of trouble for future modprobing and require a reboot to clean up properly. Fix it by returning -EINVAL if no values are given for the parameter, and also avoid any nastyness from BUG_ON while at it.

2007-11-05ACPI: thinkpad-acpi: fix brightness_set error pathsHenrique de Moraes Holschuh

2007-11-05ACPI: thinkpad-acpi: allow for syscall restart in sysfs handlersHenrique de Moraes Holschuh
Map an mutex_lock_interruptible() error return into ERESTARTSYS, as the only possible error from mutex_lock_interruptible is EINTR, and that will only happen if signal_pending() causes the mutex lock attempt to abort. This still allows signals to be delivered ASAP, which is much nicer than just doing mutex_lock, and still shadows userspace from EINTR when SA_RESTART is active. Problem reported by Peter Jordan.

2007-11-05ACPI: thinkpad-acpi: prefer standard ACPI backlight level controlHenrique de Moraes Holschuh
Newer Lenovo BIOSes support the standard ACPI backlight brightness interface (_BCM, _BQC, _BCL). It should be used instead of the native thinkpad backlight brightness control interface when possible. This patch disables the native brightness support in the driver by default when we detect that the standard ACPI interface is available. The local admin can still enable it using the module parameter "brightness_enable". Note that we need to detect the standard ACPI backlight interface only in boxes for which we would load the native backlight interface in the first place, and that no ThinkPad BIOS has _BCL but misses the other methods, so the detection routines can be really simple.

2007-11-05ACPI: thinkpad-acpi: add brightness_force parameterHenrique de Moraes Holschuh
Add a "brightness_enable" module parameter that allows the local admin to force the backlight support to not be enabled. It can also be used to force the backlight support to be enabled, but that is currently a no-op as the backlight support is enabled by default when available. This will be changed by a different patch. Signed-off-by: Henrique de Moraes Holschuh <hmh@hmh.eng.br> Signed-off-by: Len Brown <len.brown@intel.com>
2007-11-05ACPI: thinkpad-acpi: support 16 levels of brightness (v3)Henrique de Moraes Holschuh
Lenovo ThinkPads often have 16 brightness levels in EC, and not just eight levels like older ThinkPads. They also have standard ACPI backlight brightness control. We detect the number of brightness levels by the presence of a BCLL package with 16 entries. If BCLL is not there, we assume eight levels (Z6*). If it is there, but it doesn't have 16 entries, we assume eight levels (T60). Otherwise we assume sixteen levels (T61, X61, etc). We don't use _BCL because it can have side-effects in thinkpads. Thanks to Thomas Renninger <trenn@suse.de> for notifying me of this potential problem. Using the standard ACPI backlight brightness control *instead* of the native thinkpad backlight control is a better idea, though. A different patch will take care of this.

2007-11-05ACPI: thinkpad-acpi: revert keymap changesHenrique de Moraes Holschuh
Revert commit fba956c46a72f9e7503fd464ffee43c632307e31, "Map volume and brightness events on thinkpads". That commit made some modifications to the default keymaps that cause bad behaviour on all IBM ThinkPads if HAL doesn't know to change them into passive (on-screen-display only) events. The proper solution for IBM ThinkPads is to use the _NOTIFY version of the key codes for the IBM default map (which are not available in mainline yet), and for the Lenovo keymap, it will take some studying of the various DSDTs and testing to know the best path (which I will do shortly).

2007-10-09drivers/firmware: const-ify DMI API and internalsJeff Garzik
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.
