Subject: [PATCH 02/10] drm/i915: gen specific ring init
Date: Wed, 7 May 2014 10:26:58 -0700 [thread overview]
Message-ID: <1399483626-7540-3-git-send-email-benjamin.widawsky@intel.com> (raw)
In-Reply-To: <1399483626-7540-1-git-send-email-benjamin.widawsky@intel.com>
Gen8 has already had some differentiation with how it handles rings.
Semaphores bring yet more differences, and now is as good a time as any
to do the split.
Also, since gen8 doesn't actually use semaphores up until this point,
put the proper "NULL" values in for the mbox info.
v2: v1 had a stale commit message
v3: Move everything in the is_semaphore_enabled() check
v4: VCS2 rebase
Remove double assignment of signal in render ring (Ville)
