SonyPI Driver

SonyPI Driver

[Knut.Neumann]

Hi there,

I noticed that when running the sonypi driver on my VAIO z600tek, APM Suspend does no longer work: The power button (to suspend) does no longer work and - well - it will still suspend if I force it to, by apm -s but it does not resume (powers on, but blank screen and no input gets processed).

The system is a vaio z600tek with debian potato and kernel 2.4.9 apm compiled in and enabled at boot time. Its also patched with ext3 patch and latest acpi-patch (though acpi is disabled at boot). I as well observed this behaviour with a non-acpi-patched kernel. Sonypi is compiled as module and the system will correctly suspend and resume as long as the module is not loaded. After it has been loaded once, the system will no longer resume from suspend.

I assume that is because the driver is mainly based on acpi-functionality (and thus reverse engineering), but I am not quite sure. 

If anyone has an idea, please let me know (and please cc: to me as I am not subscribed to the list)

Thank you very much in advance.

Yep, using the sonypi driver switches the laptop in a pseudo acpi
mode and APM based suspend will get disabled.

This is a known problem and there is currently no workaround
(especially since on my Vaio - a C1VE model, even the APM suspend
hangs).

You'll have to wait for ACPI suspend support in the kernel
(some support will get into the 2.5 kernel series) or choose between
the sonypi driver and APM suspend.

Of course, you can always find a workaround, in which case I and many
other Vaio owners will be grateful to you :-).

Patrick Mochel has some patches for ACPI to enable suspend-to-ram
[problems with vesafb nd evices, otherwise ok], and
I'm currently working on suspend-to-disk [will work in easy cases].
See acpi list.

Yes, I saw this and I keep looking at those, some day I might even
try them. :-)

The main problem for me now is that the current ACPI code does pretty
nothing on my laptop (Sony Vaio C1VE): no battery status, no event
recorded etc... This was already reported on the acpi list some
time ago.

I'm adding a CC: to the ACPI list just in case someone has an idea
on how to make ACPI working for me. If this is not an already known
problem just tell me and I will compile an ACPI enabled kernel again
and give additionnal details / debug info.
