ACPI / video: Add "Asus UL30A" to ACPI video detect blacklist

2013-05-30T13:35:05Z

commit c8f6d8351ba8c89d5cd4c562552ec7ec29274e31 upstream. Like on UL30VT, the ACPI video driver can't control backlight correctly on Asus UL30A. Vendor driver (asus-laptop) can work. This patch is to add "Asus UL30A" to ACPI video detect blacklist in order to use asus-laptop for video control on the "Asus UL30A" rather than ACPI video driver.

acpi/video_detect: blacklist samsung x360

2013-01-03T03:33:22Z

commit 084940d5b101e9ca91a689eb5048151b14076839 upstream. On Samsung X360, the BIOS will set a flag (VDRV) if the generic ACPI backlight device is used. This flag will definitively break the backlight interface (even the vendor interface) untill next reboot. It's why we should prevent video.ko from being used here and we can't rely on a later call to acpi_video_unregister().

acpi: add export.h to files using THIS_MODULE/EXPORT_SYMBOL

2011-10-31T23:30:34Z

These files were relying on module.h to come in via the path in an include/acpi header file, but we don't want to have instances of module.h being included from include/* files if it can be avoided. Have the files include export.h instead. Signed-off-by: Paul Gortmaker

ACPI / Video: Probe for output switch method when searching video devices.

2011-02-12T00:40:16Z

This patch reverts one hunk of 677bd810eedce61edf15452491781ff046b92edc "ACPI video: remove output switching control", namely the removal of probing for _DOS/_DOD when searching for video devices. This is needed on some Fujitsu Laptops (at least S7110, P8010) for the ACPI backlight interface to work, as an these machines, neither ROM nor posting methods are available, and after removal of output switching, none of the caps triggers, which prevents the backlight search from being entered. Tested on a Fujitsu Lifebook S7110 and Fujitsu Lifebook P8010. This probably fixes https://bugzilla.kernel.org/show_bug.cgi?id=27312 for the people who have no entry in /sys/class/backlight. This is the complete list of public (starting with "_") methods implemented on the S7110, BIOS rev 1.34: \_SB_.PCI0.GFX0._ADR \_SB_.PCI0.GFX0._DOS \_SB_.PCI0.GFX0._DOD \_SB_.PCI0.GFX0.CRT._ADR \_SB_.PCI0.GFX0.CRT._DCS \_SB_.PCI0.GFX0.CRT._DGS \_SB_.PCI0.GFX0.CRT._DSS \_SB_.PCI0.GFX0.LCD._ADR \_SB_.PCI0.GFX0.LCD._BCL \_SB_.PCI0.GFX0.LCD._BCM \_SB_.PCI0.GFX0.LCD._BQC \_SB_.PCI0.GFX0.LCD._DCS \_SB_.PCI0.GFX0.LCD._DGS \_SB_.PCI0.GFX0.LCD._DSS \_SB_.PCI0.GFX0.LCD._PS0 \_SB_.PCI0.GFX0.LCD._PS3 \_SB_.PCI0.GFX0.TV._ADR \_SB_.PCI0.GFX0.TV._DCS \_SB_.PCI0.GFX0.TV._DGS \_SB_.PCI0.GFX0.TV._DSS \_SB_.PCI0.GFX0.DVI._ADR \_SB_.PCI0.GFX0.DVI._DCS \_SB_.PCI0.GFX0.DVI._DGS \_SB_.PCI0.GFX0.DVI._DSS Signed-off-by: Michael Karcher Acked-by: Zhang Rui Signed-off-by: Rafael J.

ACPI video: remove output switching control

2010-12-14T05:04:52Z

Remove the ACPI video output switching control as it never works. With the patch applied, ACPI video driver still catches the video output notification, but it does nothing but raises the notification to userspace. Signed-off-by: Zhang Rui Signed-off-by: Len Brown
