Hi all,
In reply to #302:
> Where did you get the device names ("Dolphin", "Pinnacle", "Mercury",
etc.) and how did you figure out the protocols?
Seconded.
> Can people test Kevin's patch?
I tried it on my dell e6230, it works.
Kevin's patch do not properly take into account the fact that the e6230
has 16 and 12 bits for the MT slots, and not 15 and 11 (this is the
ALPS_BITMAP_X_BITS and ALPS_BITMAP_Y_BITS setting).
> If it works, then I'll layer the Dell I15R, I17R, 13z on top of it and
submit a patch to linux-input.
I'm a bit lost here. Has anybody kept track of the different models
encountered, and on which laptops ? I think that would help a lot (most
of the info is probably in here, but very poorly organized ; In
particular it's difficult to keep track of which laptop models, among
the ones listed, seemingly have different touchpad hardware).
Dave, what's your decision on your ACPI patch ? I haven't understood
what was the rationale behind using it, as it seemed to me that we had
enough material to drive our decision by talking to hardware directly.
If I understand correctly, you are about to forget this patch, is that
right ?
Merging all existing code (yours, mine, kevin's) is in fact easier than
the recollection of what happens where, and possibly requesting some
testing hardware (posters in this thread can be solicited).
Slightly different is the situation for the short v6 init sequence in
#280, which diverges from the usual pattern, to say the least. Not
having RESET_BAT and ENABLE in there makes the sequence functionally
different from what happens with other hardware.
In the ``seemingly different hardware category'', one could be mistaken
into listing the Dell E6230/E6430. These do have identical hardware,
except for the absence of the trackstick on the smaller E6230. My
reverse-engineering work and merge with bgamari's patches show this.
These are differentiated by querying the 0xc2c8 register, which is not
queried in Kevin's patch.
Briefly put, I think we should work making all this stuff cleaner.
