Subject: BAT bug 95634, take 4
Date: Wed, 15 Jun 2016 13:17:45 +0100 [thread overview]
Message-ID: <1465993109-19523-1-git-send-email-chris@chris-wilson.co.uk> (raw)
Since I touched upon an issue with initialisation ordering, trying to
fix an issue between init vs suspend and delayed userspace became a
whole lot more messy with a dip into drm to try and straighten out our
dev->driver->load callback.
There is one major stumbling block in the use of drm_dp_aux's i2c
adapter long before i2c is able to be used (since i2c demands
registration with userspace prior to use!). That's quietly avoided by
initialising enough of drm_dp_aux ourselves to use i2c_transfer, and a
trio of patches to expose the same functionality from i2c await
response. In the meantime, I would like to close the regression...
-Chris
