Bugzilla Bug 128863

0.18  2006-04-01
----------------
- Solved embedded controller lockups with HDAPS=1 (see hdaps comments below).
- Added new function tp_controller_try_read_row() to tp_base.
- Added extra status checks in tp_base, to catch abnormal conditions earlier.
- Restructured several functions in tp_base for clarity and reusability.
- Restructured tp_smapi attribute registration code using fancy macros, to 
  remove redundancy.
- Reduced prefetch delay and maximum retries in tp_base.
- Now locks tp_controller when making SMAPI call (just in case).
- Makefile change to fix compilation in Debian.
- Minor cleanups and added comments in tp_smapi.c.
- Major changes to hdaps patch:
  - Whenever we read data from the controller, parse all of it and
    remember the values in global vars.
  - Simplified the device model *_show functions, via the above change.
  - If the mousedev poll timer handler experiences a transient fault, use
    use last saved data from the global vars.
  - Handle delayed calibration at first opportunity, not just mousedev polls.
  - Disable mousedev poll timer when suspending, to prevent readouts before
    the resume code re-initializes the sensor.
  - Don't accept initial status 0x00, it was probably an artifact of 
    the premature mousepoll invocation.
  - When doing a sensor readout in mousedev poll, avoid time-consuming
    retries and fetches, to minimize time in softirq. This effectively 
    exorcises an embedded controller lockup Heisenbug. There may still 
    a nonzero probability of lockup, but now it's not worse than the 
    vanilla hdaps (since they do essentially the same).

Cheers, T.

tp_smapi 0.19 ebuild

https://sourceforge.net/project/showfiles.php?group_id=1212&package_id=171579

The new version 0.19 is out with a proper directory structure now.
You can just copy and rename the old ebuild.

Tobias, please change summary and url

0.19  2006-04-08
----------------
- Added new battery status attributes:
  /sys/devices/platform/smapi/BAT?/first_use_date
  /sys/devices/platform/smapi/BAT?/manufacture_date
- Bugfix in tp_base embedded controller readout 
  (missing prefetch invalidation). This apparently solves remnants of the
  the embedded-controller-lockup problem.
- "make load" now demands "HDAPS=1" if the hdaps module is loaded.
- hdaps driver patch:
  - Remember keyboard/mouse activity for 0.1sec, so that all applications
    get a chance to read it (the hardware resets its activity flag
    when it's read).

Version 0.19 fixes an embedded controller lockup, which is data loss and
possibly hardware damage (oversensitive firmware commits suicide if you talk to
it impolitely). 

Please update ASAP.

Added to Portage.
