Subject: [PATCH v2 9/9] drm/i915/gem: hide new uAPI behind CONFIG_BROKEN
Date: Thu, 29 Apr 2021 11:30:56 +0100	[thread overview]
Message-ID: <20210429103056.407067-9-matthew.auld@intel.com> (raw)
In-Reply-To: <20210429103056.407067-1-matthew.auld@intel.com>

Treat it the same as the fake local-memory stuff, where it is disabled
for normal kernels, in case some random UMD is tempted to use this. Once
we have all the other bits and pieces in place, like the TTM conversion,
we can turn this on for real.
