About dsdt of clevo 5600N

Hi all.
I'm interested of fixing the dsdt tables of my clevo 5600N but I don't find any clear information how can do it (yeah newbie here!).

I checked acpi.sf.net/dsdt and I have all the howto's and guides for begin, only I want to ask if there's any dsdt of any clevo already patched (in the repository, I can't see any).

I think that the patch of Markus Gaugush is a clean way to do what I must do for obtain the suspend on ram state on my clevo.

Thanks for any addintional information, or tips that you could tell me for helping me to do this whole thing.

Well dsdt tables fixed and loaded by initrd patch! in dmesg I could see:
-----------
Looking for DSDT in initrd ... found at beginning!
   tbget-0292: *** Info: Table [DSDT] replaced by host OS
 tbxface-0117 [03] acpi_load_tables      : ACPI Tables successfully acquired
Parsing all Control Methods:..........................................................................................................................................
Table [DSDT] - 519 Objects with 49 Devices 138 Methods 14 Regions
ACPI Namespace successfully loaded at root c0379ebc
-----
Now is right. But now which useful information can I extract from this?

How can I know if my laptop is capable of doing suspend on Ram (I supose the tipical windows supend mode)? throght the dmesg? 
Or I need more patches?


(I upload the dmesg here:  http://xarz.no-ip.org/dmesg_acpi_tables.txt)

Thanks for your info and patience.

You have to do 'cat /proc/acpi/sleep' and see if S3 is available.
Unfortunately, even if it is shown to be supported, it can't work with 2.4
kernels. Maybe try the latest 2.5 kernel, or use swsusp (swsusp.sf.net).

The 5600 supports S3, but you can forget about using it in Linux at this
moment.  There are two problems at the moment, one specific and one
general.  

Problem one is that the sleep button is not enabled for wakeup, so you
can make the laptop go S3, but you can't wake it up.  It took me weeks
to figure this out.  The experiment ended with a BAD BAD hack to enable
the sleep button for a wakeup event and at least it showed some signs of
life.  The friendly Intel ACPI developers are aware of this problem and
will fix it.

Problem two is of course simply the fact that many drivers don't support
being waked up from S3 yet.  In addition, the information for waking up
a Radeon M7 (which is in the 5600) is not really available.  You can try
the trick Ole Rohne did and repost the Radeon, but this is kludge.

Search the acpi-devel list archives for details.

Actually, my M7 wakes up properly, provided I pass the acpi_sleep=s3_bios
parameter. This is, of course, in plain VGA console, as the radeonfb does
not seem to work, and since I have some serious fs problems with 2.5.x, I
dare not test it under XFree.

But then, it may be model specific.

Best regards,

acpi_sleep=s3_bios is one way to repost and comes down to exactly what Ole
Rohne did with the int10 module of XFree86.  This does not work on all
implementations.  The Right Way is to have the necessary specifications for
the chip for correct wake-up from device D3 state, or whatever is relevant
for system S3.  These specs are NOT available for the Radeon M7.

Did you check the newer radeonfb driver versions? There is some power
management code in there, but apparently only meant for Apple laptops.
Maybe it would be possible to use that code? Disclaimer: I know virtually
nothing about PCI power management, so there is a chance I don't have any
clue on what I am talking about.

A while back I posted a link to this code (by Benjamin Herrenschmidt and ATI
engineers) to the acpi-devel list.  The code supports device D2 and not D3.
Even Ben has his doubts (as posted to mailing lists) about sleep support on
graphics chips.

Thanks to all for the info, in special to Charl CP.Botha  that his help in this and other things about linux in a clevo 5600.

I'll tried the linux kernel 2.5.69 and the clevo the initrd patch for the dsdt and the laptop sleeps well but never wakes up as Charl tell in last e-mail (Suposed missing acpi information about suspend wake buttons on clevo 5600)

<Not acpi related>
About the radeonfb in 2.5.x I must say that it doesn't work yet, only the vesa fb.
Another problem that I notice with 2.5.X is that I can't be able to wake the Xwindows. The radeon Xfree 4.3 driver seems not work with 2.5.x kernels and I must test the kernels with the vesa xfree driver.Any hints?

</not acpi related>

Cheers,
