From c499faebd77d1d9656774406fe259cd5369af12c Mon Sep 17 00:00:00 2001 From: Jason Ekstrand Date: Thu, 18 May 2017 13:51:16 -0700 Subject: [PATCH] anv: Add an option to abort on device loss This is mostly for running in our CI system to prevent dEQP from continuing on to the next test if we get a GPU hang. As it currently stands, dEQP uses the same VkDevice for almost all tests and if one of the tests hangs, we set the anv_device::device_lost flag and report VK_ERROR_DEVICE_LOST for all queue operations from that point forward without sending anything to the GPU. dEQP will happily continue trying to run tests and reporting failures until it eventually gets crash that forces the test runner to start over. This circumvents the problem by just aborting the process if we ever get a GPU hang. Since this is not the recommended behavior most of the time, we hide it behind an environment variable.
