Subject: Re: shutting down individual devices
Date: Mon, 26 Jul 2004 16:42:53 +0200 [thread overview]
Message-ID: <20040726144253.GA4428@rap.rap.dk> (raw)
In-Reply-To: <20040720135143.GA16058-EittdKFJ/bZ/SzgSGea1oA@public.gmane.org>
I tried to shut down other devices and it worked (eth0).
So I think the reason why nothing seemed to work for me with the
devices shown below, is that no actions are defined in the DSDT for
these devices on the machine.
My idea is then if I can write my own DSDT for this, compile it and load
it, and then hope for the hardware to work for me. Is that possible?
Device (AC97)
{
Name (_ADR, 0x001F0006)
Name (_PRW, Package (0x02)
{
0x05,
0x03
})
}
Device (AC05)
{
Name (_ADR, 0x00090000)
}
Could I throw in some methods to power down the sound device, ala
what is done for the USB? here is an entry for one of the USB
interfaces. Or could I damage the hardware by trying out a new DSDT?
Device (USB1)
{
Name (_ADR, 0x001D0000)
OperationRegion (USBO, PCI_Config, 0xC4, 0x04)
Field (USBO, DWordAcc, Lock, Preserve)
{
RSEN, 2
}
Name (_PRW, Package (0x02)
{
0x03,
0x00
})
Method (_PSW, 1, NotSerialized)
{
If (Arg0)
{
Store (0x03, RSEN)
}
Else
{
Store (0x00, RSEN)
}
}
Method (_S3D, 0, NotSerialized)
{
Return (0x02)
}
Method (_S4D, 0, NotSerialized)
{
Return (0x02)
}
}
Best regards
