From 938b9306be240ada0e592f2bf59f428c6e0e5717 Mon Sep 17 00:00:00 2001 From: Vivek Kasireddy Date: Wed, 4 Nov 2015 16:10:15 -0800 Subject: igt/kms_rotation_crc: Add a new subtest to exhaustively test for fence leaks (v3) In this subtest, as a first step, MAX_FENCES+1 number of framebuffers are created backed up by objects that have multiple GGTT views (normal and rotated). Next, we have the i915 driver instantiate a normal view followed by a rotated view. We continue doing the above MAX_FENCES + 1 times. v2: - Add a igt_require() to check if there is enough GTT space left for MAX_FENCES+1 framebuffers. (Tvrtko) - Make data2 local to test_plane_rotation_exhaust_fences(). (Tvrtko) - If there is a failure, deallocate all the previously allocated framebuffers before asserting. v3: Close the gem handle if set_tiling or addfb fails.
