It works well. commit 45d63644d28c34202a97bd812f6c46c853e97d28 Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Fri Jan 10 21:13:56 2014 +0000 tests/gem_pipe_control_store_loop: Delete bogus assertion target_bo->offset was just being used to verify that the batch submission worked and fortunately was not being relied upon for any subsequent conditions. However, address 0 is valid and so the assertion itself was bogus as it is possible (almost assured with full-ppgtt) for the target_bo to be located at address 0. Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=72984 Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Verified.Fixed. Closing old verified. |
