From: Tvrtko Ursulin <tvrtko.ursulin@linux.intel.com> To: igt-dev@lists.freedesktop.org Cc: Intel-gfx@lists.freedesktop.org Subject: [Intel-gfx] [PATCH i-g-t v2] i915/gem_engine_topology: Generate engine names based on class Date: Wed, 22 Jan 2020 14:40:28 +0000 [thread overview] Message-ID: <20200122144028.27346-1-tvrtko.ursulin@linux.intel.com> (raw) In-Reply-To: <20200122101043.21347-1-tvrtko.ursulin@linux.intel.com> From: Tvrtko Ursulin <tvrtko.ursulin@intel.com> With the introduction of dynamic subtests we got one step closer towards eliminating the duality of static and dynamic engine enumeration. This patch makes one more step in that direction by removing the dependency on the static list when generating probed engine names. v2: * Fix __for_each_static_engine iterator. * Prefix unknown engines with 'unknown'.
