Compaq Evo N800v: I have a fixed DSDT table

Compaq Evo N800v: I have a fixed DSDT table

[Daniele Boffi]

Hi folks!

Stimulated by the recent discussions on the list, I made some important
progress on my (already satisfactory) fixed DSDT table for Evo N800v.

You can find it at

www-dimat.unipv.it/~boffi/compaq/custom-dsdt.hex

I'll send it to acpi.sf.net tonight.

IMPORTANT NOTICE: I am using Bios revision F.18A as of 2 Jan 03. Previous
release might not work.

What is working:

- batteries (BAT0  BAT1)
- ac_adapter (ACAD)
- button (lid  power  sleep)
- embedded_controller (C0D0)
- fan (I have 4 of them: C1D9  C1DA  C1DB  C1DC)
- power_resources (C0CF  C141  C155  C159  C15D  C166  C1D5  C1D6  C1D7  C1D8)
- processor (C000)
- thermal_zone (I have three of them, first one is CPU, TZ1  TZ2  TZ3)
- Fn F7/F8 work (panel brightness)
- pressing the lid button turns the screen off as expected

What can be improved

- sleep states: echo 5 works (shutdown), echo 4 works (it invokes swsusp)
                other states do nothing
- CPU: (*) I can change throttling state fine
       (*) performance always report P0, however I checked the following:
           turning AC/battery produced the desired effects (P1 when on battery)
           even if it is not reported in /proc/acpi
       (*) I can swicth to P1 when on AC with "echo 1:0 > limit" (always
           doesn't appear in proc/acpi), but "echo 0:0 > limit" does not switch
           back to P0. In order to switch back, I turn AC off for a second and
           then put it back, so that the BIOS does the job for me.
- volume control buttons: are they acpi-related?

I hope this will help somebody.

Daniele

I think these are not four hardware-devices, but instead represent 4
different speed-states for the same fan.

Same for me. I also tried the swsusp patch and it works for me. It's a
little bit slow to suspend and hibernate this way, so I don't use it
very often. Making S3 (Suspend to RAM) on this machine would be really
nice, but I didn't have the time to try a newer development kernel,
yet.

> - volume control buttons: are they acpi-related?

No, they generate normal scan codes, which any program my use. Check
out lineak (http://lineak.sourceforge.net/). It works fine for
me. There are other similar tools which do the job also.

The same applies to the play/stop etc. buttons (Fn+F9). They can also
be made available to lineak or xmms.

The only buttons which bypass the kernel keyboard routines or ACPI are:

- Fn+F2 (wireless device on/off): This seems to hardwired into the
  keyboard controller. The current power state is also written to
  NVRAM, so it might even be possible to "emulate" this button from a
  program.

- Fn+F4 (Switch display output): Just seems to work for me. Haven't
  tried it with a TV attached, yet.

- Fn+F7 / Fn+F8 (display brightness): Just works for me. The ACPI
  system might be involved here.

- Fn+Scroll: Emulate numeric keypad. Just works for me, seems to be
  hard wired in the keyboard controller.

All other keys are either ACPI controlled (Sleep, Power) or can be
accessed from user space.

Regards,

Stephan

Can I ask what version of ACPI you are running?  The lid button and the 
panel brightness doesn't work for me on my Evo N800c with bios F.18a. 
 I'm hoping the problem is a difference in the software, not in the 
hardware.

Thanks
Mike

I think your problem is related to Xfree. I am using XFree4.2 with the
configuration file you can download at

www-dimat.unipv.it/~boffi/compaq/XF86Config

I am using the X module synaptic for the touch pad (it is great), if you don't
have it you should comment out the references to it.

In any case, I am using acpi-20021212-2.4.20

Good luck,

Daniele

You are correct.  The trick was to not load dri in the modules section. 
 That has some downsides, but nothing I can't live with.

One thing I did notice is that if I hit the lid button while running X, 
the screen blanks, but when I release it, the screen is not restored (it 
just stays blank with the backlight on).  Hitting ctrl-alt-f1 to get to 
a text console and hitting the lid button again fixed the problem, and I 
could then hit ctrl-alt-f7 to get back to X.

Thanks for the help.

Mike

This is a known problem with newer version of XFree. I had that problem with
Red Hat 9, then I came back to RH8 where the lid behavior is normal.
