Mattia, I didn't want to mess with the DMI stuff, but I suspect we can 
probably drop the setup callbacks there and just enable them on all 
hardware that supports these methods. We possibly also want to be 
calling the ECON method on the SNC since some codepaths in the tables 
seem to depend on them - but I'm also worried to a certain extent on how 
much that might change driver interactions with some machines.

Thanks for these patches, do they enable wwan activation on Vaio Z
series, too?

Currently the stock kernel sony-laptop with all patches floating around
on lkml did not make the wwan interface show up from the turned off
state. The only way to do that is using the 0.6 version for Vaio Z from
http://www.basyskom.org/~eva/log_installation_vaio_z21vnx.html

Thanks and all the best

I expect so.

Sigh. I could have saved some amount of time if these patches had 
actually been sent to the mailing list. They're functionally equivalent, 
except mine integrate with the rfkill class correctly and check whether 
the hardware is present before creating the rfkill device.

Umpf, bad.

I found that out only recently that there is this module floating
around.

Ok, I will give your patches a testing spin on my Vaio Z11.

One question: Should I apply the patches Mattia posted some time ago 
(9 of them if I remember correctly) and your patch on top of them, or
apply your patch to current -rc8?

Best wishes

Mine doesn't depend on any of Mattia's patches, but should work with 
them.

Ok, here some first test result:
kernel 2.6.29-rc8 plus only your patch.

Nice.

Now I have loads of rfkill switches:
/sys/class/rfkill# for i in rfkill*/name ; do echo $i; cat $i; done
rfkill10/name
5100AGN
rfkill11/name
sony-wifi
rfkill12/name
sony-bluetooth
rfkill13/name
sony-wwan
rfkill15/name
hso-0


The interesting thing is that the last one hso-0 does not do anything
when echoing 0/1 onto the state, while echoing 0/1 onto rfkill13/state
the device is actually dis/enabled.

Fine.

Especially since I can now also turn on and off the bluetooth device.
Great.

Thanks a lot!

Best wishes

Norbert

Another result, but this time a bit negative: Your patch does not (well
I know) incorporate the stuff turning off the secondary nvidia card on
the device having Stamina-Speed switch. 

Outcome of that is that the power consumption is much higher with your
modules about 8-10W (measured with powertop). So I have to go back to
the other module.

As far as we can tell, the handling of the handover is consistent across 
all dual-GPU nvidia laptops[1]. The right place for support to end up is 
in the kernel component of the nouveau drivers.

Whatever the nouveau drivers are? You mean those based on the kernel
mode swching? Unfortunately that is far from prime time, and we need
power saving now.

I will take a look over the weekend maybe I can add a patch ontop of
yours that only does that, taken from the code in the special vaio-Z
sony-laptop module.

Ok, here is the code.

For those interested I Cc the  sony-vaio-z-series@lists.launchpad.net
group where I first found that modules.

You need:
	kernel 2.6.29-rc8	(maybe it works with all from .28 on)
	the patch Matthew sent 
	the attached patch

Together you get full rfkill support for bluetooth/wwan/wifi, plus afais
stamina-speed mode setting.

Maybe Matthias the creator of the sony-laptop for vaio-zseries modules
can take a look at the patch and see if I missed something.

Matthias: sony_led_off and sony_dgpu_sta is never used, is that
intentional? And also the #define SONY_WMMX_GUID I couldn't find being
used anywhere.

Maybe Matthew can take a look and fix the compile warnings in function
‘sony_ovga_dsm’ (there are some!).

My intention is that we do not digress too far from the kernel code of
sony-laptop making eventual merging possible.

Best wishes

Norbert

Too much of honour ;) I only took the in-kernel module as a base for my 
experiments. But I'll have a look this weekend.

sony_led_off is an experiment vehicle only, and sony_dgpu_sta can be used to 
query the power state of the nvidia adapter. It's in there for demonstration 
purposes.

I'm aware of that. Most are in debug code, though, which can be removed safely 
without changing the functionality.

I checked the code and I think you didn't miss anything. Looks good.

You can safely get rid of this, its the GUID of the only valid (but broken) 
WMMX function in the DSDT code. It was a dead end.

> Maybe Matthew can take a look and fix the compile warnings in function
> ‘sony_ovga_dsm’ (there are some!).

Check the attached patch, it does away with the compile warnings. I've removed 
the warnings in functional code and put ifdefs (ugh!) around debug only code. 
You can just remove it if you don't like it, I'm only keeping it around for 
reference.

I've also backported Matthews patch to the standard Suse 11.1 kernel so that 
we can test it more easily.

Done, looks quite promising. The "wireless" switch on the Z21 works now, and 
apparently there is some script magic in opensuse that operates all rfkill 
switches, so it kills all wireless devices at once. Not bad.

The new init sequence for SN07 also enables all the special keys, even the 
speed/stamina switch now generates an ACPI event, as well as S1, S2 and Eject. 
But you cannot distinguish them, they all report the same event.

All in all - nice.

You mey need the additional SN07 call to get the actual key press, see
the code in sony_acpi_notify.

Can you try this? I don't have physical access to an appropriate machine 
right now, so I've got no idea if it actually works. I suspect that 
we'll need another table of event mappings for the 0x93 type. This is on 
top of mainline - it migrates everything over to my guesses about how 
this interface is meant to be used, adds support for querying the event 
type in the 0x93 event case and uses it all for the rfkill support as 
well. If this works I'll send the patch series.

Tried it but acpi_listen still reports the same events:

Hm. Try changing 0x93 to 0x90 in the notify handler.

That did the trick, now different syms are reported.

BUT:
- suddenly the sony-laptop module is convinced that the *hardware*
  rfkill switch is always turned on, always. Not even reloading an older
  sony-laptop helped. Rebooting neither. Shutting down and rebooting
  with an older sony-laptop as default made wifi show up again.
  I am not sure if cold booting into the latest version of your patch
  will work, haven't tried till now, sorry, will do tomorrow.

- S1 and S2 do adjustment of the brightness, while Fn-F5 and Fn-F6 do
  not do anything, but this is probably only configuration stuff.

Thanks as usual

Hmm. Don't /think/ I did anything that should affect that, but it's 
possible. If it's reproducable, can you try commenting out the 
sony_call_snc_handle calls in sony_nc_function_setup and see if they 
change the behaviour? You'll probably need to reboot in between.

Ok, sounds like the mapping needs to be changed. Can you let me know 
which ACPI events are generated for each key?

Yes it does.
A vaio SR user sent me this list for 0x9c that after a call to SN07(202)
becomes:

+       { 0x01, SONYPI_EVENT_ANYBUTTON_RELEASED },
+       { 0x82, SONYPI_EVENT_PKEY_P1 },

0x9c as well? Interesting. Easy enough to generalise that code, I guess. 
If we don't have a match, maybe we should just send the scancode with 
KEY_UNKNOWN and let hal remap them?

well, I was thinking of a two layer lookup keyed on the event code
(0x9[02ce]).

> If we don't have a match, maybe we should just send the scancode with 
> KEY_UNKNOWN and let hal remap them?

the problem is that the decoded keypress (after the SN07 call) generates
duplicates, i.e.: 0x81 is fn+f1 for the 0x92 case and some "Mode" key
for 0x9c the an SR model.
I guess sending the whole combination as the scancode would do the trick
(0x9c81).
But as long as we can make it consistent with what sony-laptop currently
sends to userspace then we should try to have a map.

Mm. That ought to work. Still, if we can get a map from the new models, 
it might not be too urgent.

Couldn't test that since several SONYPI_EVENT* are not defined in
current -rc8 plus Matthew patch. And I didn't want to try it out.

the above code was not meant to be tested. What you should do instead is
changing the line (after Matthew's patch):
	if (ev == 0x92 || ev == 0x93) {
in sony_acpi_notify to
	if (ev == 0x92 || ev == 0x93 || ev == 0x90) {
load the driver with debug=1 and press the unrecognized Fn keys.
You *should* get a bunch of "unknown input event XX" in the kernel log,
with those we can build the necessary mappings for your specific model
(hopefully not just yours).

I tried your patch together with Mattia's remark:

and it works fine.

Regarding the key press events I did what Mattia said (loading with
debug=1): Some created an "Unknown event" in the log, some not.

S1:
sony-laptop: sony_acpi_notify, event: 0x20
sony-laptop: sony_acpi_notify, event: 0x10

S2:
sony-laptop: sony_acpi_notify, event: 0x20
sony-laptop: sony_acpi_notify, event: 0x11

Fn-F5 (brightness -)
sony-laptop: Unknown event: 90 85
sony-laptop: sony_acpi_notify, event: 0x85

Re: [PATCH] sony-laptop: support rfkill via ACPI interfaces

[Matthew Garrett]

Interesting. These don't seem to match your earlier numbers, but instead 
look much more like the 0x92-style events. Do any of the other keys 
generate events? This one should be consistent with the events you're 
reporting.

With this patch I get:
S1
sony-laptop: Unknown event: 90 90
sony-laptop: sony_acpi_notify, event: 0x90
sony-laptop: sony_laptop_report_input_event, event not known: 144

Fn-F9

Fn-F10
sony-laptop: sony_acpi_notify, event: 0x15
sony-laptop: sony_acpi_notify, event: 0x3b


and now also Fn-F5 and Fn-F6 do the right thing, i.e., adjust the
brightness, while S1 and S2 are doing nothing.

Thanks a lot and all the best

Norbert

Re: [PATCH] sony-laptop: support rfkill via ACPI interfaces

[Matthew Garrett]

Ok, this one should cover it. Thanks for testing! S1 and S2 will just 
generate events that can be bound with your desktop environment or 
xbindkeys or something similar.

Mattia, how do you feel about this approach? If you're happy enough I 
can send this as a patchset.

Did I mess something up, but now I get
	sony-laptop: sony_acpi_notify, event: 0x20
	sony-laptop: sony_acpi_notify, event: 0x38
	sony-laptop: unknown input event 38
for S1.

Why do I have again different numbers ....

But the Unknwon even is gone, now we have unknown input event.

But it works, now S1 can be bound in gnome shortcuts menu.

Thanks.

Yes, that's fine - it's just coming from 
SONYPI_EVENT_ANYBUTTON_RELEASED, which doesn't map onto an actual event. 
Can you do one last thing and (with debugging enabled) try flicking the 
rfkill switch, then let me know what event it generates?

Besides loads of remove foo bar stuff I get:

for turning from on to off:
sony-laptop: sony_acpi_notify, event: 0x93
sony-laptop: sony_laptop_report_input_event, event not known: 147
sony-laptop: unknown input event 93


for turning to from off to on
sony-laptop: sony_acpi_notify, event: 0x93
sony-laptop: sony_laptop_report_input_event, event not known: 147
sony-laptop: unknown input event 93


One more thing: Can you check the "Eject" button, I always forgot that
one (press-release):
sony-laptop: Unknown event: 90 9f
sony-laptop: sony_acpi_notify, event: 0x9f
sony-laptop: sony_laptop_report_input_event, event not known: 159
sony-laptop: unknown input event 9f
sony-laptop: Unknown event: 90 1f
sony-laptop: sony_acpi_notify, event: 0x1f

Ok, thanks. That's sent as a separate event type, which makes this 
easier. It may need some further work to figure out whether it's going 
from on to off or off to on, but I'll see if I can figure that out.

Sorry, CD eject button. That would be nice, because the hardware eject
button is a pain to press for me with my big fingers ;-)

Thanks, worked perfectly. And my gnome desktop opened the CD drive
without even thinking.

Great.

What remains for me for the moment is some decent rfkill switching
utility GUI. Something that shows the names and one can press the button
next to the name to turn off and on ...

Best wishes

Re: [PATCH] sony-laptop: support rfkill via ACPI interfaces

[Matthew Garrett]

Ok, and here's what I consider to be the "final" version for now. It 
cleans up the event handling (it turns out that the event value 
corresponds to the SN00 value required to call the corresponding 
function) and adds support for the external switch to flag the devices 
as being in HARD_BLOCKED state. Tested on a P series (remotely), if 
someone could check it on a Z and ideally a TT, that would be great. I 
think it's otherwise basically complete for keyboard and rfkill 
handling.

Looks good to me. I asked Michael to test one of you earlier versions
on his TT and he seems to be happy about it (apart from an oops
somewhere in the tty_release path[1] which is unlikely to be related to
sony-laptop).

Please send your series in, I'll then rebase my patches and push to Len.

After looking at this, I think we actually want to be calling SN07(20C) 
on these machines - they implement an 0x127 function in the C function 
slot which also calls GECR. I suspect that this corresponds to the 
larger number of programmable buttons, so should be added to another 
table. Something like the following - some amount of tidying up 
required. That would avoid needing to add a multilevel setup.

Interestingly, the recent SRs also appear to implement the 0x124 rfill 
method, but at SN07(4) rather than SN07(3). This leaves me pretty happy 
that I've got the right idea about how this all works now :)

So does that mean I should test this on on top of your "final" patch?

The Z series doesn't implement the 0x127 method, so it won't make any 
difference.

Re: [PATCH] sony-laptop: support rfkill via ACPI interfaces

[Matthew Garrett]

Ok, thanks. Can you try this instead of the other patches? I'm a touch 
concerned about the release events on the S1 and S2 buttons looking like 
the events for some of the Fn keys, which may mean that we need to find 
some way of distinguishing them.

Against which version of sony-laptop does it apply? Against kernel,
against kernel+Matthew, against yours, against kernel+Matthew+mine? I
couldn't find out ..

Thanks for taking a look into that

I'm more of the idea to provide a module option to force the setup
callback if the module is not in the DMI list.
Although for now all of the models that have SN07 and friends seem to
benefit from throwing some magic numbers at them.

My understanding about ECON is that it is always enabled if the embedded
controller is enabled. The SPIC device has the same kind of dependency
and as far as I could see ECON is always 1. So I don't think it makes
much of a difference.

A couple of comments below.

Thanks

do we really need to unregister if registering failed?
Looking at rfkill_{un,}register this seems unnecessary while an
rfkill_free seems more appropriate.
The same applies for the other rfkill setup functions.

hummm, this is very similar to the callback setup executed when matching
the snc dmi list.
On which vaio model did you get this numbers? Did you find the other
initialization path (the one dependent on the DMI list) any useful on
that model? i.e.: do you need both?

I had one machine where ECON seemed to need to be called explicitly, but 
I can't remember the details now. Calling it probably wouldn't hurt 
anything.

Yeah, I'll fix that up.

The numbers correspond to enabling all events. I couldn't think of any 
reason why we'd only want to enable a subset. The current nc setup code 
seems to enable some events and then disable them again, which I don't 
really understand.

agreed, but I need to figure out if the initialization sequence is
really the same for those new TT/Z models and the olders one (see also
below).

seems to be a TT and Z specific thing though. The DSDT on other models
doesn't provide the ECON method.

Well, the current sequence was taken from a trace in windows on a Vaio C
Type, then it demonstrated to be helpful on other models as well.
The SN07[1] method is very different from the Z and TT type to the AR, C,
FE, FZ and N so I'm starting to suspect that we're just seeing a new
generation of SNC based models. I'll see if some users with older models
can give the new sequence a go.

In the meantime can we make your sony_nc_function_setup less invasive
and depend on the DMI to match?

Yeah. As I said, I don't think there's any harm in causing it - I think 
I was getting more promising results from hotkey events in the Z when I 
called ECON, but I don't have access to that machine right now and never 
got it finished off.

Looking through, the implementation seems quite different but the 
functionality seems the same - the newer machines seem to return values 
directly, whereas older ones tended to trap into SMM. The wireless 
control (at least, the enumeration call I make) seems to be a noop on 
these older machines. It /looks/ like we can probably get some sort of 
versioning information about the interface by calling SN00. I think that 
would probably be a better approach than using DMI for this.

I've put this into rawhide, so I suspect we'll hear complaints if it 
breaks things for anybody.

sure, that DMI whitelist is already annoying in its current shape.

SNI4 or CFGI+0x04 is the only differing number and is returned with
SN00(4).

want to try to push your patch to mainline or would you prefer to wait?
IMO pushing it and eventually fixing support for 0x344a000[10] models is
fine. After all your snc_setup code could be easily plugged into the DMI
list for the time being and Z and TT users would be happy.

(snip)

The second byte seems to be the most consistent here - 0x4a for the 
models currently handled by the nc code, 0x4d for the tt and z, 0x55 for 
the p. I've no idea whether this is a monotonically increasing version 
string or a bitmask of supported functionality, but it ought to be 
enough to key off to begin with.

Might as well push it and see what happens?

Oh, do you have a vaio type P DSDT to share?

Sure, if you're ok I'll apply the patch you sent just changing the
rfkill_free and send the whole patch-set to Len tomorrow morning (JST).

Attached. I'm now fairly sure that the second byte returned by SN00(4) 
is the gross version, with the leading byte being a subversion(!?). 
Machines with 0x4a in the second byte have the following set of methods 
(as called by SN07):

   0x33:  0x34:  0x36:  0x37:
0, 0x0101 0x0101 0x0101 0x0101
1, 0x0102 0x0102 0x0102 0x0102
2, 0x0100 0x0100 0x0100 0x0100
3, 0x0104        0x0104
4, 0x0107 0x010F 0x0107 0x010F
5,               0x0106 0x0106
6,               0x0000 0x0113
7,        0x0111        0x010A
C,               0x010C
D,               0x010D 0x010D
E, 0x0105 0x0105 0x0105 0x0105
F, 0x0103 0x0103 0x0103

They're indexed by the leading byte. Machines with 0x4d as the second 
byte have:

0, 0x0100
1, 0x0101
2, 0x0113
3, 0x0124
4, 0x0126
5, 0x0125
6, 0x011D
7, 0x0121
8, 0x0105
9, 0x0114
a, 0x0119
b, 0x0122
c, 0x0128
d, 0x0115
e, 0x0131
f, 0x12f

Machines with 0x55 as the second byte (only the P, as far as I can 
tell):

0, 0x100
1, 0x101
2, 0x113
3, 0x124
4, 0x132
5, 0x125
6, 0x11d
7, 0x121
8, 0x105
9, 0x114
a, 0x119
b, 0x122
c, 0x130
d, 0x115
e, 0x131

This actually makes me think I've been taking the wrong approach. I'm 
now guessing that the numbers returned by SN00 in the 20-2f range are 
method signatures - 0x100 is hotkeys, 0x124 is rfkill. This fits with 
the fact that SN07(0) looks to return hotkey values on the Z, whereas 
that's SN07(2) on the older hardware. Both have 0x100 returned by 
SN00(0x20). I think if we rewrite the code on this basis we can merge 
the functionality. I'll try to do that tomorrow and also (with luck) get 
the hotkey stuff on the Z back up.

Mind waiting until I've tried this rewrite? It'd be nice to know what a 
bunch more of these methods do, but I guess that's less urgent.

Actually slightly more complicated than that - some are only stored on 
certain OS versions. Here's a more complete table.

   0x33:  0x34:  0x36:  0x37:

0, 0x0101 0x0101 0x0101 0x0101
1, 0x0102 0x0102 0x0102 0x0102
2, 0x0100 0x0100 0x0100 0x0100
3, 0x0104 0x0113 0x0104
4, 0x0107 0x010F 0x0107 0x010F
5,               0x0106 0x0106
6,               0x0113 0x0113
7,        0x0111        0x010A
C,               0x010C
D,               0x010D 0x010D
E, 0x0105 0x0105 0x0105 0x0105
F, 0x0103 0x0103 0x0103

The way that 0x113 moves around leaves me pretty sure that calling SN07 
without checking what the function signature is is not a good idea. I'll 
rewrite my patch.

If that's really a function signature, why are some of the slots empty? If 
you're supposed to read the CFGI first via SN00, that would not make much 
sense. However, it makes sense if the function is encoded by the slot and a 
hole (i.e. Zero) means that the function is not supported or disabled.

If you're right though, it means that "0x124" on all new-style models (those 
with SN07 method) must always operate the killswitch. I might be able to find 
that out from the decompiled DSDT. Right now I only checked the Z series DSDTs 
(Z11 and Z21) and of course they are very similar. But I would be very 
interested to see the code of  functions called for the other "slot 3" 
methods, like 0x0104 and 0x0113. If you had some DSDTs to share...

I thought that at first, but 0x113 is the same code on the machines I 
checked even though it moves around. 0x100 appears to be "Get hotkey 
event" on the newer hardware even though it's not in slot 2.

The P, TT and Z all seem to have 0x124 as killswitch - the 0x113 and 
0x104 methods don't seem to be killswitch related, as far as I can tell. 
Mattia linked to a set of DSDTs earlier in the thread.

Ok no rush, I'll wait until you're done before submitting the batch for
.30.

PS: you forgot the type P DSDT attachment. ;)
