Phi Template Version: @(#)sac_nextcase %I% %G% SMI This information is Copyright 2009 Sun Microsystems 1. Introduction 1.1. Project/Component Working Name: Laptop Hotkey Support 1.2. Name of Document Author/Supplier: Author: Kerry Shu 1.3 Date of This Document: 11 January, 2009 4. Technical Description ACPI video extensions define generic ACPI methods for brightness control and display switch control. We've added the ACPI brightness hotkey support in PSARC/2008/021. The Laptop Hotkey Support case will add the ACPI display switch hotkey support. (With the integration of LSARC/2008/519, we can do display switch via user defined hotkey already.) Since there is no generic ACPI specification for other hotkeys, most vendors just define their own specific ACPI based hotkey method. This case will also add Toshiba specific ACPI hotkey method support for: 1. Fn + ESC: audio mute On/Off 2. Fn + F1: screen lock 3. Fn + F3: suspend to RAM(on S3 capable platform) 4. Fn + F8: wireless LAN On/Off 5. Fn + F9: touchPad On/Off Other vendor specific hotkey method support can be added in future after we get the related documentations. 4.1 Details We'll enhance existing acpi_drv to support the generic ACPI display switch method and introduce a misc module (acpi_toshiba) for Toshiba specific ACPI hotkey method to support hotkeys on Toshiba laptops. Other vendor specific hotkey support can be added one by one in different misc module(acpi_xxxx) in the future. Generally, vendor specific method also covers the brightness and display switch control which are defined in generic ACPI video extensions. In our design, acpi_drv is responsible to load vendor specific module(s). If there is a vendor specific method module being loaded successfully, acpi_drv won't enable its ACPI video extension support and all the hotkeys including brightness and display switch will be handled by vendor specific module. Otherwise, acpi_drv enables its ACPI video extension support to handle just brightness and display switch hotkey. ------------- --------------- ------------------ | audio mute| ... | screen lock | ... | Suspend to RAM | ------------- --------------- ------------------ ^ ^ ^ | | | | | | _____________________________________________________________ |Gnome | | Keyboard Shortcuts Application | | | |___________________________________________________________ | ^key grabbing and keysym translation | | _____________________________________________________________ |Xserver (LSARC XXXX) | | | | post key to input queue | | | (keycode + modifier) | | Xserver hotkey driver | | | receive hotkey sysevents | |___________________________________________________________ | ^hotey sysevent user land | -------------------------------|------------------------------- kernel | | _____________________________________________________________ |ACPI hotkey driver | | ------------ --------------- ------------- | | | acpi_drv | | acpi_toshiba | ... | acpi_xxxx | | | ------------ --------------- ------------- | |____________________________________________________________| ^acpi event | | Hotkey Pressing Figure 1 hotkey architecture Pressing laptop hotkey(it is "Fn + ?" on Toshiba laptops. Other laptops may be different.) will generate ACPI event to ACPI hotkey driver module. The hotkey driver module will then generate a sysevent to notify Xserver. Xserver receives hotkey sysevents and translates the sysevent to a special key input with (keycode + modifier) and then posts the key to the input queue. Gnome Keyboard Shortcuts Application grabs the key and then takes action to call the corresponding application. The changes in Xserver for hotkey support will be covered with a LSARC case. 4.2 Interface sysevent --------- Interface level: Project Private The EC_ACPIEV class defined in PSARC/2006/601 Battery Project will be extended to include below subclasses: ESC_ACPIEV_DISPLAY_SWITCH ESC_ACPIEV_SCREEN_LOCK ESC_ACPIEV_SUSPEND_TO_RAM ESC_ACPIEV_AUDIO_MUTE ESC_ACPIEV_WLAN ESC_ACPIEV_TOUCHPAD 4.3 References LSARC/2008/519 Hot Key Based Display Device Switch (dispswitch) PSARC/2006/601 Battery Project PSARC/2008/021 HAL Power Management Support 6.

I did a research on other vendors' hotkey implementation, they are either based on ACPI or they can generate scan code like other normal key. For the first case, acpi_xxxx can handle; For the second case, they can be handled by current keyboard drivers.

Would it be possible to let users create their own set of hotkeys? Even if the hotkeys are burned into the HW, it'd be nice to be able to let the user input each one and assign a symbol to each. This would be a good workaround for lack of support for a specific laptop. At base what I'm asking for is that it be possible to provide a list of hotkeys and their symbolic mappings via a method other than an ELF kernel module -- a text file, say, read at boot time or at ttymon/Xorg start time (so the parsing could be done in user-land).

In many cases, the keys are just "keyboard keys" and they should be handled through the keyboard driver. In other cases, they are all "ACPI" events. I would like those to be presented as keyboard keys; and then you can easily use GNOME something or other to bind an event to the key press.

However, the problem, as I understand it, is that as rich as the USB spec is, there are still some keys that lack standard keyboard defines in the USB spec -- e.g. the WLAN toggle key, and LCD backlight control keys. I think the current plan has the X server generate key events (X11 events) so that tools like gnome can operate on them the same way as ordinary keys.

That's really difficult to use. An ioctl() that can take a list of mappings provided by a user-land program that parses a configuration file would be better. And either way there needs to be a mechanism by which it is possible to discover what the actual hotkey keyboard layout is (i.e., "what laptop is this?").

That's why our current design leverages Gnome shortcuts application. Uses can define their own hotkeys(shortcuts) as usual. This project will make the dedicated hotkeys also and always work.

One of us is missing something. Let's say I've a laptop A but no vendor support, so no ACPI driver that recognizes the ACPI hotkeys. In order to use the ACPI hotkeys then I'll have to: write a kernel module as if I were the vendor. But if I understand correctly the basic kernel ACPI driver can catch ACPI hotkeys -- it just doesn't know what to do with them. So I propose that you provide a *configurable* mapping of ACPI hotkey IDs to keyboard events. That way instead of having to write a kernel module for my unsupported laptop I need only write a little text file.

There are three levels of mapping: 1) mapping some arbitrary ACPI event to a system event consumable by userland 2) mapping the system event to an X11 key event 3) mapping the X11 key event to an action The first of these is highly platform-specific, and is what is driven by the kernel configuration. Its not entirely clear to me that a table driven approach *could* be used in the general case -- how each BIOS enables and delivers ACPI events might be highly vendor specifc. I don't know that this *is* the case, merely postulate that it *might* be. Even if a table driven approach *were* possible, changing the configuration would probably require fairly detailed knowledge of the platform's BIOS -- well beyond the scope of what one might expect users to be able to configure. The second is an artifact of the implementation, and no user should need or want to change it. (Its a simple identity map.) The third is user configurable today, and will remain so. So, while I do wish that an easier user configuration were available for these ACPI events (the first of those translations), or that the industry had standardized a bit more here, the reality is that this probably isn't practical, at least not at this point. -- Garrett > Nico > From Kerry.Shu@sun.com Mon Jan 12 10:33:07 2009 Received: from newsunmail1brm.central.sun.com (newsunmail1brm.Central.Sun.COM [129.147.62.245]) by sac.sfbay.sun.com (8.13.8+Sun/8.13.8) with ESMTP id n0CIX7os027030 for ; Mon, 12 Jan 2009 10:33:07 -0800 (PST) Received: from brm-avmta-1.central.sun.com (brm-avmta-1.Central.Sun.COM [129.147.4.11]) by newsunmail1brm.central.sun.com (8.13.7+Sun/8.13.7/ENSMAIL,v2.2) with ESMTP id n0CIX2ps003692; Mon, 12 Jan 2009 11:33:06 -0700 (MST) Received: from pmxchannel-daemon.brm-avmta-1.central.sun.com by brm-avmta-1.central.sun.com (Sun Java System Messaging Server 6.2-3.04 (built Jul 15 2005)) id <0KDD00905FJ6UP00@brm-avmta-1.central.sun.com>; Mon, 12 Jan 2009 11:33:06 -0700 (MST) Received: from brmea-mail-4.sun.com ([192.18.98.36]) by brm-avmta-1.central.sun.com (Sun Java System Messaging Server 6.2-3.04 (built Jul 15 2005)) with ESMTP id <0KDD0011AFJ5KO70@brm-avmta-1.central.sun.com>; Mon, 12 Jan 2009 11:33:05 -0700 (MST) Received: from fe-amer-10.sun.com ([192.18.109.80]) by brmea-mail-4.sun.com (8.13.6+Sun/8.12.9) with ESMTP id n0CIX5Qu028993; Mon, 12 Jan 2009 18:33:05 +0000 (GMT) Received: from conversion-daemon.mail-amer.sun.com by mail-amer.sun.com (Sun Java System Messaging Server 6.2-8.04 (built Feb 28 2007)) id <0KDD00I01F9LWV00@mail-amer.sun.com> (original mail from Kerry.Shu@Sun.COM) ; Mon, 12 Jan 2009 11:33:05 -0700 (MST) Received: from [10.1.48.131] by mail-amer.sun.com (Sun Java System Messaging Server 6.2-8.04 (built Feb 28 2007)) with ESMTPSA id <0KDD0012KFIRHAC0@mail-amer.sun.com>; Mon, 12 Jan 2009 11:32:52 -0700 (MST) Date: Mon, 12 Jan 2009 10:32:59 -0800 From: Kerry Shu Subject: Re: Laptop Hotkey Support [PSARC/2009/016 FastTrack timeout 01/16/2009] In-reply-to: <20090112170137.GN6457@Sun.COM> Sender: Kerry.Shu@sun.com To: Nicolas Williams , Henry Zhao Cc: "Garrett D'Amore" , Casper.Dik@sun.com, Darren Kenny , Phi Tran , PSARC-ext@sun.com, laptop-hotkeys-iteam@sun.com Message-id: <496B8CDB.7040601@sun.com> MIME-version: 1.0 Content-type: text/plain; format=flowed; charset=us-ascii Content-transfer-encoding: 7BIT X-PMX-Version: 5.4.1.325704 References: <200901120401.n0C41A5b012275@sac.sfbay.sun.com> <20090112162659.GD6457@Sun.COM> <496B7142.5000308@Sun.COM> <200901121643.n0CGh76h046188@dm-holland-02.uk.sun.com> <496B74B4.8010203@sun.com> <20090112170137.GN6457@Sun.COM> User-Agent: Thunderbird 2.0.0.14 (X11/20080519) Status: RO Content-Length: 1724 Nicolas Williams wrote: > On Mon, Jan 12, 2009 at 08:49:56AM -0800, Garrett D'Amore wrote: >> I had suggested a similar approach (using keyboard keys) -- actually my >> original suggestion went a step further, and suggested that this module >> could emulate a USB keyboard and generate USB boot-protocol HID keyboard >> events. >> >> However, the problem, as I understand it, is that as rich as the USB >> spec is, there are still some keys that lack standard keyboard defines >> in the USB spec -- e.g. the WLAN toggle key, and LCD backlight control keys. >> >> I think the current plan has the X server generate key events (X11 >> events) so that tools like gnome can operate on them the same way as >> ordinary keys.

A kernel module, hotkey driver, is to init and get the hotkey ACPI events. The key mapping is done in Xserver. Xserver maps each hotkey with same "keycode + modifier" no matter what laptop is. For your suggestion, we still need to define different unused keycode for each hotkey in configuration file. Anyway, per my understanding, we can hardly find enough unused keycode for them. (Henry can comment more). And it's also platform dependent.

Do you read the misc/ directories appearing in the kernel's module search path and load every misc module whose name matches acpi_*, and expect at most one of them to return 0 from _init()? > > Are these modules expected to test for platform compatibility by > > probing around in the module's _init(9E) function? > > Yes. And per my understanding, the ACPI method string should be unique > per vendor. OK. I would think that a safer way to do this would be to have a new registry in /etc (acpi_modules?) that maps from method string to module name to be loaded. But as long as you've tested your search method, and it doesn't cause undue hardship, and this is the _only_ thing that's likely to be using it, I guess I don't have a strong feeling about this. -- James Carlson, Solaris Networking Sun Microsystems / 35 Network Drive 71.232W Vox +1 781 442 2084 MS UBUR02-212 / Burlington MA 01803-2757 42.496N Fax +1 781 442 1677 From Nicolas.Williams@sun.com Mon Jan 12 10:45:09 2009 Received: from sunmail5.uk.sun.com (sunmail5.UK.Sun.COM [129.156.85.165]) by sac.sfbay.sun.com (8.13.8+Sun/8.13.8) with ESMTP id n0CIj8Us027326 for ; Mon, 12 Jan 2009 10:45:09 -0800 (PST) Received: from nwk-avmta-2.sfbay.sun.com (nwk-avmta-2.SFBay.Sun.COM [129.145.155.6]) by sunmail5.uk.sun.com (8.13.8+Sun/8.13.8/ENSMAIL,v2.2) with ESMTP id n0CIiuHa019277; Mon, 12 Jan 2009 18:45:03 GMT Received: from pmxchannel-daemon.nwk-avmta-2.sfbay.sun.com by nwk-avmta-2.sfbay.sun.com (Sun Java System Messaging Server 6.2-3.04 (built Jul 15 2005)) id <0KDD00L1FG326900@nwk-avmta-2.sfbay.sun.com>; Mon, 12 Jan 2009 10:45:02 -0800 (PST) Received: from binky.Central.Sun.COM ([129.153.128.104]) by nwk-avmta-2.sfbay.sun.com (Sun Java System Messaging Server 6.2-3.04 (built Jul 15 2005)) with ESMTP id <0KDD00DA1G31N890@nwk-avmta-2.sfbay.sun.com>; Mon, 12 Jan 2009 10:45:02 -0800 (PST) Received: from binky.Central.Sun.COM (localhost [127.0.0.1]) by binky.Central.Sun.COM (8.14.3+Sun/8.14.3) with ESMTP id n0CIhr7L009938; Mon, 12 Jan 2009 12:43:53 -0600 (CST) Received: (from nw141292@localhost) by binky.Central.Sun.COM (8.14.3+Sun/8.14.3/Submit) id n0CIhrGQ009937; Mon, 12 Jan 2009 12:43:53 -0600 (CST) Date: Mon, 12 Jan 2009 12:43:53 -0600 From: Nicolas Williams Subject: Re: Laptop Hotkey Support [PSARC/2009/016 FastTrack timeout 01/16/2009] In-reply-to: <496B8998.6030503@sun.com> To: "Garrett D'Amore" Cc: Kerry Shu , James Carlson , Darren J Moffat , laptop-hotkeys-iteam@sun.com, PSARC-ext@sun.com, Phi Tran Message-id: <20090112184352.GW6457@Sun.COM> MIME-version: 1.0 Content-type: text/plain; charset=us-ascii Content-transfer-encoding: 7BIT Content-disposition: inline X-PMX-Version: 5.4.1.325704 References: <200901120401.n0C41A5b012275@sac.sfbay.sun.com> <496ADAB3.5070906@Sun.COM> <496AE12B.2030003@sun.com> <18795.17896.562807.896342@gargle.gargle.HOWL> <496B861E.5050401@sun.com> <20090112181412.GS6457@Sun.COM> <496B8998.6030503@sun.com> X-Authentication-warning: binky.Central.Sun.COM: nw141292 set sender to Nicolas.Williams@sun.com using -f User-Agent: Mutt/1.5.7i Status: RO Content-Length: 1207 On Mon, Jan 12, 2009 at 10:19:04AM -0800, Garrett D'Amore wrote: > I think there's some confusion. > > There are three levels of mapping: > > 1) mapping some arbitrary ACPI event to a system event consumable by > userland > 2) mapping the system event to an X11 key event > 3) mapping the X11 key event to an action I got that. > The first of these is highly platform-specific, and is what is driven by > the kernel configuration.

I was under the impression that the ACPI event mechanism was generic but the symbolic assignments were not. If the event mechanism itself is not generic, then I agree that support for it will have to come from a kernel module and cannot be table driven.

There is no basic kernel ACPI driver which can catch hotkey ACPI events for all laptops of different vendor. We need to have different corresponding hotkey driver to initialize the hotkey method and catch the ACPI notify per vendor.

I've seen no fewer than three different approaches vendors use, and the details differ for each (I don't know what Apple uses): 1. keys send PS/2 or USB key events. This requires no work other than the user establishing the handling using the gnome applications. 2. keys are handled using microcontroller firmware internally. This requires no work on anyone's part. They just work. 3. keys are handled using ACPI or similar BIOS, and require OS support. In the current proposal, adding support for a laptop that does this requires code modifications in ON. The proposal could probably be refined so that unbundled versions could be developed, but ultimately someone would still need to develop code no matter what. The complete anarchy here (some might call it "freedom for vendor innovation") is not helpful. It would be nice if there were standards for this stuff. IMO, most of the vendors aren't overly inclined to care much though, since they all deliver their own Windows platform drivers already, and usually they don't care that much about making things easy for other operating systems. Even the vendors that cooperate and provide information (Toshiba) might not want to develop common standards, since their openness (or rather the closedness of their competitors) might actually be a competitive edge for them in certain markets. (And developing common standards is *expensive* usually, since committees and politics then get involved.) -- Garrett > -John > From gdamore@sun.com Mon Jan 12 13:03:01 2009 Received: from sunmail4.singapore.sun.com (sunmail4.Singapore.Sun.COM [129.158.71.19]) by sac.sfbay.sun.com (8.13.8+Sun/8.13.8) with ESMTP id n0CL30WP019883 for ; Mon, 12 Jan 2009 13:03:01 -0800 (PST) Received: from nwk-avmta-1.SFBay.Sun.COM (nwk-avmta-1.SFBay.Sun.COM [129.146.11.74]) by sunmail4.singapore.sun.com (8.13.4+Sun/8.13.3/ENSMAIL,v2.2) with ESMTP id n0CL2rFl010393; Tue, 13 Jan 2009 05:03:00 +0800 (SGT) Received: from pmxchannel-daemon.nwk-avmta-1.sfbay.Sun.COM by nwk-avmta-1.sfbay.Sun.COM (Sun Java System Messaging Server 6.2-3.04 (built Jul 15 2005)) id <0KDD0011JMGVKT00@nwk-avmta-1.sfbay.Sun.COM>; Mon, 12 Jan 2009 13:02:55 -0800 (PST) Received: from sca-es-mail-2.sun.com ([192.18.43.133]) by nwk-avmta-1.sfbay.Sun.COM (Sun Java System Messaging Server 6.2-3.04 (built Jul 15 2005)) with ESMTP id <0KDD00HUVMGUK8D0@nwk-avmta-1.sfbay.Sun.COM>; Mon, 12 Jan 2009 13:02:55 -0800 (PST) Received: from fe-sfbay-10.sun.com ([192.18.43.129]) by sca-es-mail-2.sun.com (8.13.7+Sun/8.12.9) with ESMTP id n0CL2scF001195; Mon, 12 Jan 2009 13:02:54 -0800 (PST) Received: from conversion-daemon.fe-sfbay-10.sun.com by fe-sfbay-10.sun.com (Sun Java System Messaging Server 6.2-8.04 (built Feb 28 2007)) id <0KDD00901MFKEO00@fe-sfbay-10.sun.com> (original mail from gdamore@sun.com) ; Mon, 12 Jan 2009 13:02:54 -0800 (PST) Received: from [10.7.251.172] by fe-sfbay-10.sun.com (Sun Java System Messaging Server 6.2-8.04 (built Feb 28 2007)) with ESMTPSA id <0KDD00M86MGJ6SA0@fe-sfbay-10.sun.com>; Mon, 12 Jan 2009 13:02:44 -0800 (PST) Date: Mon, 12 Jan 2009 12:53:16 -0800 From: "Garrett D'Amore" Subject: Re: Laptop Hotkey Support [PSARC/2009/016 FastTrack timeout 01/16/2009] In-reply-to: <18795.42741.945636.587473@gargle.gargle.HOWL> Sender: Garrett.Damore@sun.com To: James Carlson Cc: Kerry Shu , laptop-hotkeys-iteam@sun.com, PSARC-ext@sun.com, Phi Tran Message-id: <496BADBC.2000401@sun.com> MIME-version: 1.0 Content-type: text/plain; format=flowed; charset=ISO-8859-1 Content-transfer-encoding: 7BIT X-PMX-Version: 5.4.1.325704 References: <200901120401.n0C41A5b012275@sac.sfbay.sun.com> <496ADAB3.5070906@Sun.COM> <496AE12B.2030003@sun.com> <18795.17896.562807.896342@gargle.gargle.HOWL> <496B861E.5050401@sun.com> <18795.36533.261864.95194@gargle.gargle.HOWL> <496B938D.7040800@sun.com> <18795.38844.898816.546129@gargle.gargle.HOWL> <496B9C86.9090403@sun.com> <496BA304.9060900@sun.com> <18795.42741.945636.587473@gargle.gargle.HOWL> User-Agent: Thunderbird 2.0.0.14 (X11/20080616) Status: RO Content-Length: 1187 James Carlson wrote: > Garrett D'Amore writes: > >> In retrospect, perhaps having a separate directory under /kernel would >> be better, and then vendors could deploy their own acpi modules without >> having to touch the acpi_drv binary. >> > > If that's where we go, then I'd rather see an /etc registry, as we do > with other forms of hardware/module ID and aliasing. > > >> There's a possibly different approach as well -- you could have acpi_drv >> be a nexus, and create child nodes with the node name of the form >> "acpi,TOS1900" or somesuch.

Kerry describes the general picture how mapping is done in X server. Since not enough unused keycode(s) are available, we use "transit mapping" method in which the same keycode (in the current design, it is 127, which is not being used) and modifier are used for all possible keysysms (events), a mapping to a desired keysym is made prior to key/modifier posting, and an unmapping made after. > > Regards, > Kerry > >> >> Nico From casper@holland.sun.com Mon Jan 12 14:31:36 2009 Received: from newsunmail1brm.central.sun.com (newsunmail1brm.Central.Sun.COM [129.147.62.245]) by sac.sfbay.sun.com (8.13.8+Sun/8.13.8) with ESMTP id n0CMVZTB023687 for ; Mon, 12 Jan 2009 14:31:36 -0800 (PST) Received: from nwk-avmta-2.sfbay.sun.com (nwk-avmta-2.SFBay.Sun.COM [129.145.155.6]) by newsunmail1brm.central.sun.com (8.13.7+Sun/8.13.7/ENSMAIL,v2.2) with ESMTP id n0CMVXGo006674; Mon, 12 Jan 2009 15:31:35 -0700 (MST) Received: from pmxchannel-daemon.nwk-avmta-2.sfbay.sun.com by nwk-avmta-2.sfbay.sun.com (Sun Java System Messaging Server 6.2-3.04 (built Jul 15 2005)) id <0KDD00C0LQKLB400@nwk-avmta-2.sfbay.sun.com>; Mon, 12 Jan 2009 14:31:33 -0800 (PST) Received: from dm-holland-02.uk.sun.com ([129.156.101.225]) by nwk-avmta-2.sfbay.sun.com (Sun Java System Messaging Server 6.2-3.04 (built Jul 15 2005)) with ESMTP id <0KDD004WNQKK6390@nwk-avmta-2.sfbay.sun.com>; Mon, 12 Jan 2009 14:31:33 -0800 (PST) Received: from holland (room101.Holland.Sun.COM [10.16.117.40]) by dm-holland-02.uk.sun.com (8.13.8+Sun/8.13.8/ENSMAIL,v2.2) with ESMTP id n0CMVTkR062475; Mon, 12 Jan 2009 22:31:29 +0000 (GMT) Date: Mon, 12 Jan 2009 23:31:29 +0100 From: Casper.Dik@sun.com Subject: Re: Laptop Hotkey Support [PSARC/2009/016 FastTrack timeout 01/16/2009] In-reply-to: <496B770C.2040306@Sun.COM> Sender: casper@holland.sun.com To: Darren Kenny Cc: Nicolas Williams , Phi Tran , PSARC-ext@sun.com, Kerry.Shu@sun.com, laptop-hotkeys-iteam@sun.com Message-id: <200901122231.n0CMVTkR062475@dm-holland-02.uk.sun.com> MIME-version: 1.0 Content-type: text/plain; charset=us-ascii Content-transfer-encoding: 7BIT X-PMX-Version: 5.4.1.325704 References: <200901120401.n0C41A5b012275@sac.sfbay.sun.com> <20090112162659.GD6457@Sun.COM> <496B7142.5000308@Sun.COM> <200901121643.n0CGh76h046188@dm-holland-02.uk.sun.com> <496B770C.2040306@Sun.COM> Status: RO Content-Length: 523 >Totally agree, but I believe (but could be mistaken) that the issue is that >different laptops will generate different ACPI events - so the mapping from ACPI >event to X event isn't consistent, and I think that this is where we would need >a text document to allow people to do this mapping in the field....

Yes, the platform specific module (hotkey driver) is simple. So is the interface (we use sysevent). Hotkey driver is responsible to tell which hotkey is pressed and generates corresponding hotkey sysevent (by calling ddi_log_sysevent()). The hotkey keymapping work is done in server.

Do I think that all we need to document as the interface these modules use is: 1) the actual event names (and any payload details) 2) ideally, if there is some interface to ACPI itself that these modules should use, then those details. Anyway, I'm not too worried at the moment... both of those sets of details can just be Project Private for now.

(Is that what how they're > classified in the materials?) Yes, 1) is classified as Project Private for now. We've listed current defined subclass. for 2), we uses acpica interface(PSARC/1998/300). It's project private.
