TiBook trackpad in benh's kernel?

TiBook trackpad in benh's kernel?

[Michel Lanners]

Hi all,

Anyone else seen this? I can't get the trackpad on my TiBook working
with benh's latest tres (rsync'ed a few days ago).

I tried adding a few printk's, but there seem to never be any data
coming from the trackpad. ALso, the 'trackpad' tool claims there is no
trackpad.

Ideas? I do think it is detected on bootup:

adb devices: [2]: 2 c4 [3]: 3 1 [7]: 7 1f
ADB keyboard at 2, handler 1
Detected ADB keyboard, type ISO, swapping keys.
event1: Event device for input1
keybdev.c: Adding keyboard: input1
input1: ADB HID on ID 2:2.c4
event2: Event device for input2
input2: ADB HID on ID 7:7.1f
ADB mouse at 3, handler set to 4 (trackpad)
event3: Event device for input3
mouse1: PS/2 mouse device for input3
input3: ADB HID on ID 3:3.01
adb: finished probe task...

Thanks

Michel

Can it be that the old "booting cmode 32 kills trackpad" bug is still
alive and bit you? Did you try booting using cmode:16 or cmode:8 ?

Yeah, exactly right. cmode:32 and cmode:16 kill the trackpad; cmode:8
works OK. Plus, I am able to run XF4 in 32 bpp, even with cmode:8 set.

Go figure...

Cheers

Michel

Yeah, that one is really weird ;)

I noticed that lately, Apple changed Darwin trackpad code so that instead of
reading the 8 bytes of the config register, changing them, and writing them
back, it always write hard coded default values (doesn't read).

So I guess there might be a problem when reading the ADB datas from the
trackpad (timing issue) and rewriting those bogus datas cause the trackpad
to die.

I'll do some more experiments asap.

Ben.

        Seems to work for me.  I'm using his 2.4.4-pre1 tree rsync'ed
on April 12.  I am using cmode:32, too.

        Oops, sorry, I lied.  I boot in cmode:8 (but run X in 32bpp).
