RE: ACPI Compaq Presario

RE: ACPI Compaq Presario

[Troy Schultz]

In my daily digest of ACPI messages I see you have a Compaq Presario
2700 Notebook and are trying to get Linux running.

Here is a link to my web page with my experiences with my 2710CA
notebook and Linux. 
http://www.schultzcentral.org/notebook/notebook.html

I have made some changes to my DSDT and have fairly good ACPI support. 
I do have battery and thermal, and can pick between two CPU speeds.  I
have not tried Suspend/Resume as I have no need for it at this time.

Please send me a copy of your /proc/acpi/dsdt file and I'll compare it
to the ones I have on file.  I should be able to send you a "corrected"
DSDT that will run on your system.

Best Regards
- Troy

I have a 2701 EA and have documented my experiences on
http://dude.noc.clara.net/~faye/compaq2701ea/

I created a patch which includes the 0709 ACPI, nocorruption and also
Firewire and USB patches.  All the hardware works on my laptop and I
have Battery, AC, Thermal, Processor, Events and Alarms.

I've repeated the patches with 0725 but I haven't yet tested that
sufficiently to put it on the website.

It's possible the 2700 is similar enough to the 2701 to have the same
DSDT in which case you could just compile the patched kernel, install
and go.  My DSDT is also available on that page separately so you could
check before installing.

My advice would be not to install it as your main kernel until you are
satisfied everything is working correctly (or at least better than your
old kernel did!)

RE: ACPI Compaq Presario

[A.MAINS]

Hello

I have seen your website and have considered doing this. Troy kindly
offered to  edit my DSDT and I will give that a try. Your DSDT may work
as the 2700 and 2701 are similar. I think the only difference may be the
screen size and possible the CPU speed (I have 1.0 Ghz while the 2701
probalby has a 1.2 GHz). 

Thanks!

RE: ACPI Compaq Presario

[A.MAINS]

Hello

I tried your Presario 2701 EA Patch on my laptop and it works great!! I
can see accurate battery status as well as my CPU Temperature (Windows
Could not do that!) 

I will be trying suspend / sleep and hopefully apply the klaptop patch
so I can see battery information on the desktop. 

Thanks For the Help!

ACPI-0272: *** Info: Table [DSDT] replaced by host OS

[A.MAINS]

Hello

I patched my kernel with Faye's really nice kernel patch a few days
back. IT ran successfully for a few boots then I get this message
constantly at boot-up followed by a lockup.

ACPI-0272: *** Info: Table [DSDT] replaced by host OS

I reinstall Linux and repatch the kernel and all is well but the problem
persist a few boots later.

Does anyone have any suggestions?

Thanks For The Help!

ACPI Compaq Presario

[A.MAINS]

[-- Attachment #1: Type: text/plain, Size: 1045 bytes --]

Hello
 
I am new to this list and I have had a problem in which has been bugging
me for the longest time. I am running linux on a Compaq Presario 2700US
Laptop with Kernel 2.4.18 with ACPI Patch 20020726 along with
kacpid.patch (which I am not sure does anything for my system). This
machine in very similar to the newer Evo Laptops as well as the Presario
1700 and 700 Line of notebooks in terms of the BIOS and hardware
configurations.  
 
Anyway, ACPI compiled well into my system. Unfortunately after doing a
lot of research, it is almost useless to me. I know ACPI is under
development but also understand that Battery Status and Power Status is
fairly well implemented. I can not get either to work. Does anyone have
experience with these types of machines in linux? I would be very
interested in hearing about some experiences.  Seeing the remaining
battery as well as if the system is on AC or battery is my goal.
 
I do cats to /proc/acpi/battery/BAT1/Status and info, yielding "battery
not present". 
 
Thanks in advance for any help!

Re: ACPI Compaq Presario

[Sourav K Mandal]

Hi,

I have the Presario 2800, which is the sister machine to
the Evo N800.  A quick search on the archives will show
my messages on getting things to work, and similar 
experiences for other Compaq Presario users.

A synopsis of my functionality as relating to ACPI
(I'm using 2.4.18+acpi-20020709+nocorruption.2+swsusp9):

* No battery entry in /proc/acpi, so I'm 
flying blind.  Another user notes that fan policy
is handled at the machine level, so no ACPI 
interface for the fan, either.

* Suspend to disk and sleep on lid-closing works, 
provided X has only run w/o DRI since the last 
power up; once you fire up X w/ DRI enabled, neither
will work unless you reboot.

* Haven't played with setting CPU throttling policy,
but the /proc/acpi/processor tree seems complete, and
the speed stepping from 1.6GHz to 1.2GHz happens 
automatically.

* Device hot swap works, sort of.  I can monkey around
with the floppy, but the CDRW/DVD has to be present at
boot for Linux to appreciate its existence.  Not sure
about the battery since the entry for the primary
battery has yet to work ...

Only the first of these issues is a show stopper.

The one thing I'll try tonight is to deactivate 
ACPI debugging in the kernel config, to see if that
has any effect.  Other than that, I'm out of ideas
beyond waiting for new patches and patching the DSDT.


Regards,

Sourav

Sorry for plugging this, but I need victims^H^H^H^H^H^H^Htesters for my
kludge.  Maybe one day it'll become a feature.  Your 2800 has a Radeon,
which is good, and probably an intel 845 chipset, which is even better.

http://cpbotha.net/dri_reinit_kludge.html has patches (and binaries) so that
the Radeon DRI drivers release DRM/AGP resources across VT switches if no 3D
apps are running at that moment.  This means if you have a chvt before
suspend, resuming will work.

These patches also include (just like DRI CVS) our fixes for the Radeon DRI
VT (console) switch bug.

Charl

Try to follow this steps:

- Get Intel tools from
  http://www.intel.com/technology/iapc/acpi/downloads.htm

- Dump your dsdt table with the Intel ACPI tool
  acpidump /proc/acpi/dsdt > dsdt.asl

- You should have obtained a .asl (ACPI Source Language) file. This file
  is bugged and this is your problem. As first pass, check there are PnP
  and others entries like:
  Name(_HID, "*PNP0C0B") and suppress the *

- Get the Intel ACPI compiler and compile your table while ignoring
  errors:
  iasl -tc -i dsdt.asl
  You should get a dsdt.hex file.

- Get your kernel sources and copy this file into drivers/acpi
  drivers/acpi/osl.c and modify the file osl.c file with this patch:

- Compile your kernel, install, reboot and cross your fingers.

I tested this on an Evo and I got battery status I haven't had before.
There is a lots of others errors in the dsdt table, this is only a
beginning thanks to David Douard.

RE: ACPI Compaq Presario

[A.MAINS]

Thank You so much! I read intel's instructions on this and they made
minimal sense to me as I am not proficient in linux (yet not "newbie").
I will try your steps later and I thank you for taking the time to write
them out!

Andrew
