Phis in /proc/bus/input/devices same for all devices?

Phis in /proc/bus/input/devices same for all devices?

[CIJOML]

Hi all,

I use 2.6.20-mh1 patch and would like to differ devices based on Phis, but it 
is the same for all devices??

I: Bus=0005 Vendor=045e Product=007c Version=0035
N: Name="Microsoft Five Button Mouse"
P: Phys=00:0D:88:8E:AB:2F
S: Sysfs=/class/input/input19
H: Handlers=mouse1 event6
B: EV=7
B: KEY=1f0000 0 0 0 0 0 0 0 0
B: REL=103

I: Bus=0005 Vendor=045e Product=007b Version=0039
N: Name="Microsoft Bluetooth keyboard"
P: Phys=00:0D:88:8E:AB:2F
S: Sysfs=/class/input/input20
H: Handlers=kbd event7
B: EV=12000b
B: KEY=10f80 44007 ffe01878 800d7ff febeffdf f3cfffff ffffffff fffffffe
B: ABS=700 0
B: LED=107

I: Bus=0005 Vendor=046d Product=b3e3 Version=2503
N: Name="Logitech Bluetooth Mediapad"
P: Phys=00:0D:88:8E:AB:2F
S: Sysfs=/class/input/input21
H: Handlers=kbd event8
B: EV=12000f
B: KEY=7fff 2c3027 bf004440 0 0 1 10f80 8807c007 ffe67bfa d9415fff febeffdf 
ffefffff ffffffff fffffffe
B: REL=40
B: ABS=301 0
B: LED=1f

Shouldn't be there it's BDADDR?

Thanks for reply

please post this question to LKML. I am not sure that is the right
approach. Currently we fill in phys and uniq like this:

        strncpy(hid->phys, batostr(&src), 64);
        strncpy(hid->uniq, batostr(&dst), 64);

Maybe the input or HID subsystem should be changed to also export the
uniq values to udev.

Marcel

Hi Marcel,

are there any patches available to support uniq? I really want to have easy 
setup of my 2 same diNovo desktops keyboarad sets each with different keymap 
etc...

Dimitri thank you a lot for support so I can push Xguys now ;)

Input core does export uniq in /proc/bus/input/devices so now it is
up to individual drivers to populate this field in input_dev
structure.

Hi Dmitri,

I watched at 2.6.23 and this is still not done yet. Are there any patches 
available to use???

Hi Michal,

the source is always the host (meaning the adapter) and the destination
is always the device.

Xorg just reads lines from devices and match devices against it. So Phis makes 
configuration easier ;), because only one line is enough to match device.

it makes sense to make it analogous to the USB driver, where the phys
includes the USB path. The equivalent for Bluetooth is the source plus
destination.

I don't know how "Phis" suppose to work, but I might think it is better
using vendor and product ID for matching.

Marcel how can you differ what is src and what is dst, when device can connect 
first time from hub to keyboard and later keyboard to hub?

Re: Phis in /proc/bus/input/devices same for all devices?

[CIJOML]

I need this for differing Option "XkbModel" in Xorg, so I can bind to each
device it's model and has correct xev's scancodes based on model.
So I prefer to have as Phis just only BDADDR, because for me this doesn't make 
sense to have there device to which keyboard connect. Then I should have 1 
section for each receiver, which is stupid.

Section "InputDevice"
        Identifier  "Bluetooth Keyboard"
        Driver      "kbd"
        Option  "Name"  "Bluetooth HID Boot Protocol Device"
        Option  "Phis"        "BDADDR"
        Option      "XkbRules"  "xfree86"
        Option      "XkbModel"  "dinovo"
        Option      "XkbLayout" "us"
EndSection

and so on for every other BT keyboard I own.

Hi Dmitry,

there are correct values, but not in 
/proc/bus/input/devices, where is value non of my devices owns.

So where is that damned bug, that I don't see those uniq BDADDRESSes there?
