[edk2-devel] [PATCH] Ps2KbdCtrller: Make wait for SUCCESS after BAT non-fatal
Posted by Sean Rhodes 3 years, 10 months ago 
From: Matt DeVillier <matt.devillier@gmail.com>

Recent model Chromebooks only return ACK, but not
BAT_SUCCESS, which causes hanging and failed ps2k init.
To mitigate this, make the absence of BAT_SUCCESS reply
non-fatal, and reduce the no-reply timeout from 4s to 1s.

Tested on google/dracia and purism/librem_14
