ACPI Backlight Driver

224 posts in this topic

Recommended Posts

New version 1.2:


  • Added Boolean property in info.plist "BQC use index" to be use if your _BQC returns an index to _BCL entries (not tested)
  • Added an optional DSDT optimization : you can add a method SAVE with same parameters than _BCM and on the same device in order to split the DSDT code that set the backlight value in the PWM control register (usually located in EC) and the DSDT code that save the value in CMOS (usually in the RTC second bank of RAM : OperationRegion (xxxx, SystemIO, 0x72, 0x02) but triggered by a SMI interrupt to ensure CMOS checksum computation)

---------------------------------------------------------------------------------------------------------------

New version 1.1:

  • Added : look at power supply status at start up
  • Code correction : more checks on pointers and function return

---------------------------------------------------------------------------------------------------------------

This is a driver for laptops which backlight are controlled by ACPI Methods: if you have _DOS _BCL _BCM _BQC in you DSDT. A good reading for DSDT editing if need is Advanced Configuration and Power Interface (ACPI) Specification 4.0a APPENDIX B: Video Extensions.

This driver provides native backlight management for laptops with backlight managed by ACPI : slider in the display pref pane and sun bezel when you press backlight up/down hotkey (with an other driver than can understand your keyboard Fn keys...), power management by the OS : dim before sleep, reduce level when AC is unpluged.

It replaces an other driver I've written.ACPIBacklightDisplay.kext This old driver shall be removed.
Tested on SL 10.6.8 and Lion 10.7.0 to 10.7.2. May works on older version, but not tested.
Reported to work on 10.6.7.

Pre requested: having AppleBacklightDisplay loaded.
For this, you must have this properties injected among others by DSDT _DSM+DTGP (or graphics enabler ? or EFI strings...):

"AAPL,HasPanel",
Buffer (0x04)
{
0x01, 0x00, 0x00, 0x00
},

"AAPL,Haslid",
Buffer (0x04)
{
0x01, 0x00, 0x00, 0x00
},

"AAPL,backlight-control",
Buffer (0x04)
{
0x01, 0x00, 0x00, 0x00
},

"@0,backlight-control",
Buffer (0x04)
{
0x01, 0x00, 0x00, 0x00
},

"@0,AAPL,boot-display",
Buffer (0x04)
{
0x01, 0x00, 0x00, 0x00
},

"@0,built-in",
Buffer ()
{
One
},

It works for NVIDIA and Intel graphics. Seems problematic for some ATI users for the moment. (ATI is always more complicated!!)

There also must be this device in DSDT, in the \_SB scope:

Scope (\_SB)
{
...
Device (PNLF)
{
Name (_HID, EisaId ("APP0002"))
Name (_CID, "backlight")
Name (_UID, 0x0A)
Name (_STA, 0x0B)
}
...
}

If you don't have the _DOS Method, add a fake one in the GPU device (IGPU, GFX0... or what ever the name, it is the parent of the device where you find _BCL, _BQC, _BCM).

Method (_DOS, 1, NotSerialized)
{
//nothing to do
}

If you have several devices with _BCL _BCM _BQC the driver will take the first it finds, so you will have to find which one is the good one to do another DSDT trick. For this locate in ioreg on which device the graphic driver is loaded. Then add this into PNLF:

Method (_BCL, 0, NotSerialized)
{
return (\_SB.PCI0.IXVE.IGPU.LCDD._BCL())
}

Method (_BCM, 1, NotSerialized)
{
\_SB.PCI0.IXVE.IGPU.LCDD._BCM(Arg0)
}

Method (_BQC, 0, NotSerialized)
{
return (\_SB.PCI0.IXVE.IGPU.LCDD._BQC())
}

Method (_DOS, 1, NotSerialized)
{
\_SB.PCI0.IXVE.IGPU._DOS(Arg0)
}

Replacing _SB.PCI0.IXVE.IGPU and _SB.PCI0.IXVE.IGPU.LCDD of my example with your good path.

Then install this kext in S/L/E (with Kext Utility or similar !)
ACPIBacklight.kext.zip

If all goes right, you shall see this on the kernel log:
ACPIBacklightPanel: Found Backlight Device: LCDD
ACPIBacklightPanel: ACPI Method _DOS found. Device path: _SB.PCI0.IXVE.IGPU
ACPIBacklightPanel: ACPI Methods _BCL _BCM _BQC found. Device path: _SB.PCI0.IXVE.IGPU.LCDD
ACPIBacklightPanel: Version 1.0

Hello. I tried your kext, but don't understand some things. Your kext is not going loaded.

 

Should I remove the AppleBacklight.kext / AppleBacklightExpert.kext from system?

Your kext is not going to be loaded and I see nothing in kernel.log

There combo-picture in attach.

 

Forgot to say, I'm in 10.7.2 11C57.

I have _BCL _BCM _BQC at the display, but no _DOS in IGPU.

Thanks, you are right. Now driver loaded and gives the records in kernel.log. I found the backlight progressbar in the settings, but when I use Fn + down/up backlight, it doesn't show any picture..

 

 

(with an other driver than can understand your keyboard Fn keys...)

 

will try to do it, I found your WMI thread.

Ok, let me know how it loads, but I think you will have to develop a new personality (kext PlugIns) for dell laptop.

Can you post this kind of table:

post-740414-1316350316_thumb.png

 

You can take EeePCWMIController as an implementation template and take a look at the linux file dell-wmi.c I've put in reference to find the GUID, methods ID and etc.

 

As far as I can see in a XPS 1340 DSDT I've downloaded, I shall be possible.

Good luck

I'm sorry, I'm not sure when I can find that table

I sent PM actually before found this post.

ok, it loads normal, but I have no clue how I can fix it for my keyboard (that I wrote in PM).

 

Now backlight works using Fn+F5 down and Fn+F12 up. But in keyboard it is Fn+arrow up/down. Backlight changes when I press Fn+arrows but it doesn't have a picture in the screen.

 

http://www.amazon.com/Studio-Keyboard-Back...C/dp/B003FS14Q8

 

I have also Fn+F1 as sleep button that doesn't work at all now and Fn+F3 button that should change in windows battery mode (save or performance, it doesn't matter to launch Fn+F3).

I found also that there display switching button in the dell-wmi.c, but I have no clue how I can launch it for myself (my button it after F12 in keyboard).

Thank you for help.

 

Kernel.log now:

hi again

your driver is perfect for me except one problem i set my brightness to highest level but when reboot th brightness automatically goes to lowest level

this screen when my system is booted thanks;

and dsdt

and this log:

thanks

try this:

replace :

 

Method (_BQC, 0, NotSerialized)

{

If (ECOK)

{

Return (GBQC ())

}

Else

{

Return (GBQC ())

}

}

 

by:

 

Method (_BQC, 0, NotSerialized)

{

If (ECOK)

{

Return (GBQC ())

}

Else

{

Return (0x64)

}

}

thanks man for your replay and your help

i change it but some result as before in reboot brightness goes to min

hi

i am fixe it with adding this code(from taptun)

Device (PNLF)
	{
		Name (_HID, EisaId ("APP0002"))
		Name (_CID, "backlight")
		Name (_UID, 0x0A)
		Name (_STA, 0x0B)
		Method (SBCM, 1, NotSerialized)
		{
			Store (Arg0, ^^PCI0.LPCB.EC.BRTL)
			TRAP (TRTI, 0x1C)
		}
		Method (_BCL, 0, NotSerialized)
		{
			Return (BCL1)
		}
		Method (_BCM, 1, NotSerialized)
		{
			SBCM (Arg0)
		}
		Method (_BQC, 0, NotSerialized)
		{
			Return (^^PCI0.LPCB.EC.BRTL)

Doesn't work for me even after i have the DSDT Patches.

 

I only get

21/9/11 10:04:52.000 PM kernel: ACPIBacklightPanel: ACPI Methods _DOS _BCL _BCM _BQC found. Device path: _SB.PNLF
21/9/11 10:04:52.000 PM kernel: ACPIBacklightPanel: Version 1.0

The drivers is loaded beacause it has find ACPI backlight methods. Do you have tried to move the slider in pref pane ?

Without your DSDT I can't help more.

You should add this also in PNLF (copied from IGPU):

Method (_DOS, 1, NotSerialized)

{

Store (And (Arg0, 0x07), DSEN)

}

No slider in the preference pane unless i missed something?

 

DSDT.dsl attached.

I think AppleBacklightDisplay is not loading.

Verify with IORegistryExplorer or open Terminal and type:

ioreg -w0 -rtbSk AppleDisplayType

 

Verify on which display number your internal display is on.

if not display0 but display1, change @0, by @1, in properties injection

My display is definitely 0. AppleBacklightDisplay isn't loading as you said.

I haven't tried it, but is it possible to load this driver without recognized resolutions and graphic card? I have Intel HD, so it's not possible to run this card. I want to know is it worth of spending time :)

No idea. This driver will load but I don't know if it will be used by AppleBacklightDisplay

My display is definitely 0. AppleBacklightDisplay isn't loading as you said.

Where can I inject this into my _DSM Method? I looked at your dsdt but I could not find the above code anywhere in your dsdt, are you injecting via graphics enabler or EFI string??

 

I have PNLF method in \_SB scope

 

Any help is appreciated

Use _DSM...DTGP classical way in Device (GFX0) scope

The properties are merged with the one injected by graphic enabler

I've made a diagnostic driver to try to understand what's happening.

It will make some log lines starting by ACPIBacklightDisplay: at the end of boot, and then will refuse to load.

ACPIBacklightDisplay.kext.zip

publish the logs
