2013-11-21sony-laptop: warn on multiple KBD backlight handlesMattia Dongili1-4/+12
Some BIOS versions/Vaio models apparently ship with two nearly identical functions to handle backlight related controls. The only difference seems to be: If (LEqual (BUF1, 0x40)) { Store (0x40, P80H) Store (BUF2, Local0) - And (Local0, One, Local0) + And (Local0, 0x03, Local0) Store (Local0, ^^H_EC.KLPC) } Avoid erroring out on initialization and messing things up on cleanup for now since we never call into these methods with anything different than 1 or 0. This issue was found on a Sony VPCSE1V9E/BIOS R2087H4.

2013-10-22sony-laptop: don't change keyboard backlight settingsMattia Dongili1-17/+9
Do not touch keyboard backlight unless explicitly passed a module parameter. In this way we won't make wrong assumptions about what are good default values since they actually are different from model to model. The only side effect is that we won't know what is the current value until set via the sysfs attributes.

2013-09-24sony-laptop: convert acpi_get_handle() to acpi_has_method()Zhang Rui1-19/+9
acpi_has_method() is a new ACPI API introduced to check the existence of an ACPI control method. It can be used to replace acpi_get_handle() in the case that 1. the calling function doesn't need the ACPI handle of the control method. and 2. the calling function doesn't care the reason why the method is unavailable. Convert acpi_get_handle() to acpi_has_method() in drivers/platform/x86/sony-laptop.c in this patch.

SN06 in some cases returns an Integer instead of a buffer.

Fix scancodes returned by driver to match scancodes used to remap keys. (Before the patch FN/E returned scancode 0x1B, but to remap scancode 0x14 had to be used). The scancodes returned by the sony-laptop driver for function keys did not match the scancodes used to remap keys. Also, since the scancode was sent to the input subsystem after the mapped keysym the /lib/udev/keymap utility was confused about which scancode to report for which keysym. This patch fixes the driver so the correct scancode is shown for each key. It also adds to the documentation a description of where to find the scancodes.

2012-03-20sony-laptop: Enable keyboard backlight by defaultJosh Boyer1-1/+1
When the keyboard backlight support was originally added, the commit said to default it to on with a 10 second timeout. That actually wasn't the case, as the default value is commented out for the kbd_backlight parameter. Because it is a static variable, it gets set to 0 by default without some other form of initialization. However, it seems the function to set the value wasn't actually called immediately, so whatever state the keyboard was in initially would remain. Then commit df410d522410e67660 was introduced during the 2.6.39 timeframe to immediately set whatever value was present (as well as attempt to restore/reset the state on module removal or resume). That seems to have now forced the light off immediately when the module is loaded unless the option kbd_backlight=1 is specified. Let's enable it by default again (for the first time).

2011-10-24sony-laptop:irq: Remove IRQF_DISABLEDYong Zhang1-1/+1
Since commit [e58aa3d2: genirq: Run irq handlers with interrupts disabled], We run all interrupt handlers with interrupts disabled and we even check and yell when an interrupt handler returns with interrupts enabled (see commit [b738a50a: genirq: Warn when handler enables interrupts]). So now this flag is a NOOP and can be removed. Signed-off-by: Yong Zhang <yong.zhang0@gmail.com> Signed-off-by: Matthew Garrett <mjg@redhat.com>
