Subject: [PATCH] drm/i915: set i915 driver probe to asynchronous
Date: Wed, 19 Sep 2018 15:37:12 +0800 [thread overview]
Message-ID: <20180919073712.25463-1-ning.a.zhang@intel.com> (raw)
From: Zhang Ning <ning.a.zhang@intel.com>
when i915 is built in module, and system has built-in display, eg. eDP,
i915 will detect and active it during driver probe. it will take long
time.
set i915 driver probe to asynchrous can save kernel initial time.
