ACPI: SBS in linux-2.6.18-rc1 - Works for me!
Hello! I've tested linux-2.6.18-rc1 with Smart Battery System enabled. It works for my Acer Extensa 3002 WLMi. No compile errors or bugs at first sight. Perhaps there should be some logic in the configuration to disable the ac and battery modules. They are not needed if SBS is active. Is it possible to load sbs and i2c-ec automatically together with the other ACPI modules? On my Debian system I had to load the modules via /etc/modules.conf.

Is it possible to load sbs and i2c-ec automatically together with the other ACPI modules? On my Debian system I had to load the modules via /etc/modules.conf. I use a similar approach (for the 'old style' SBS) in /etc/rc.local: /sbin/modprobe -r battery /sbin/modprobe -r ac /sbin/modprobe i2c-acpi-ec /sbin/modprobe acpi-sbs W.r.t. enabling/disabling acbattery when sbs is selected: I'm not so sure if that would be a good idea. You build a kernel with modules, and at some later stage it is selected which modules will be actually be used. -- Johan - To unsubscribe from this list: send the line unsubscribe linux-acpi in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html

I'll send it in another email, since I already generated it for Len ;) Do you think that the whole idea is crap, or if I limit number of possible spawned threads and forsibly put current thread to sleep (which will release ACPICA executer mutex), as it happens in DSDT of nx6125 it will be possible to use it? I don't think the _idea_ is crap per se, but it would at a minimum need a thread limit. But I think it's the wrong approach: especially if you put the current thread to sleep, you really don't want another thread at all, you are really just working around a problem that is totally internal to acpi (and the AML interpreter in particular). So I think the problem really lies elsewhere, and that the whole thread approach was trying to paper over it. And having a limited set of threads is probably potentially _worse_ then what we have now. Is there no way to have the AML interpreter have some state, and just push that current interrupted state back onto the event queue, and just start executing the new one instead? That sounds like it should fix the _real_ problem - a kind of mini-scheduler for ACPI events?

RE: [patch 1/5] ACPI: Atlas ACPI driver
Jaya, Thanks for updating this patch. Note that this driver can not be accepted into the kernel without an entry being added to the MAINTAINERS file showing who is going to look after it. Preferably, that person should be inside Atlas, or have documentation or other connections or insight into the platform. I can't maintain it because I don't have any of the above, and while this platform specific driver uses ACPI, it is not part of ACPI. Yes, I know that you were following the existing examples of platform-specific drivers in /drivers/acpi, but those examples need to change (and they are a little more complex than this one b/c they scribble in their own unique ways /proc/acpi...) But think sonypi, instead. So when this does make it upstream, it will have to live outside the /drivers/acpi/ directory, and acpi should not be part of the driver name. It should build depending on CONFIG_ACPI, and should load depending on acpi_disabled, and should use ACPI routines that are exported by the ACPI sub-system (it does, though the headers are so incestuous at this point that it isn't enforced) thanks, -Len ps. I believe that you want to delete the reference below to /proc/acpi/event, yes? -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Sent: Friday, July 07, 2006 2:53 AM To: Brown, Len Cc: linux-acpi@vger.kernel.org; [EMAIL PROTECTED]; [EMAIL PROTECTED]; [EMAIL PROTECTED]; Yu, Luming Subject: [patch 1/5] ACPI: Atlas ACPI driver From: [EMAIL PROTECTED] An ACPI driver for Atlas boards, including input support.

Lets take a concrete example. CONFIG_ACPI_BUTTON It is totally nuts to to to the trouble of includeing CONFIG_ACPI and not including the few lines of code necessary to handle your power button. But at the same time, most people use =m for this because on a non-ACPI system they want as much out as possible. so we have default y conflicts with most popular use of =m default m taboo default n, no no default makes no sense, give that we get here only if CONFIG_ACPI... Seems the choices are to make the default to =m if modules are enabled, and default to y otherwise, or to simply grow the kernel and have it hard-wired to y with no choice.
