Calling all experts: Sony VAIO F11's SNC/SNY5001 device DSDT

Funky frank · May 5, 2011

Here is the dsdt of the SNC/SNY5001 device of the Sony Vaio f11 as is known for changing brightness and do other things.

Questions now to all dsdt experts:

- Does this code looks to you like there could be some functionality for enabling/disabling or sleeping/waking up the internal lvds?

- In generally can there be dsdt code that calls or wrties directly to controlling hardware registers that change a behaviour of the machine and if so can you show me a section like this?

PEG3.NGFX is the interesting nvidia device, PEGP.NGFX is for Vaios with hybrid graphics.

Regards.

Hey Frank, i have a vaio vpcf126fm. This snc, how you get it?

This is the key for the graphic aceleration solution?

Thanks!

This is what I discovered about the ACPI of the SNY5001 inside the Vaio F11 so far. It's only very rudimentary info and I don't understand the usage of the methods. SN06 seems to be a general purpose method that returns an array of available methods.

Here are some important sources. I would like to have the linux sony kernel module patched with the vaio-f11-project. But I don't have a clue how to diff patch this.

Linux Kernel 2.6.39 sony-laptop.c browser readable

Vaio-F11-Linux project diff patch

Sony_Notebook_Control_ACPI_support.webarchive.zip (Very outdated Sony ACPI descriptions)

SNC ACPI method's description (updated 04-Aug-11)

More info here.

_INI		Init, calls PHSB (0xE1, PHS (0xEA)&&1)
SODV		Switch Screen / Gfx (values 0 / 1)
SN00		Returns bytes (?) by value 0x0 to 0x4, 0x10 and 0x20 to 0x2f. See below.
SN01		Returns event status
SN02		Enable events ( 0xffff all)
SN03		Disable events ( 0xffff all )
SN04		Returns active gfx output  (var ESR),called rom SN03 param 0x8, SNF4
SN05		Sets active gfx output/brightness?  (var ESR), PHSD (0xDA, x), param: 0x9 to 0xf
SN06		Some kind of wrapper method that calls methods SNF0 to SNFF over
		method SNCM and returns the return value of SNF0 - SNFF
		Param: Buffer (0x02) { 0x0 - 0xf calling method SNF0 - SNFF, 0xXX parameter
		for SNFx-method }
