From bbc0b3cd92d9ba8bc9053e4546fbc5152a200d34 Mon Sep 17 00:00:00 2001 From: Maarten Lankhorst Date: Wed, 2 Aug 2017 11:57:32 +0200 Subject: tests: Add kms_atomic_interruptible test, v4. This tests the various parts of atomic that I want to make interruptible. Running with --debug shows the stats from __igt_sigiter_continue, which can be used to make sure that we don't fall over. The default igt kms helpers use drmIoctl, which is not intercepted by igt_while_interruptible. Only igt_ioctl is. This means we have to call the ioctls manually here. Changes since v1: - Implement interruptible DPMS checking too. - Use igt_ioctl + igt_while_interruptible, instead of the signal helper shotgun. Changes since v2: - Bump whitespace to get rid of the weird double } at same indent. - Use more newlines in the call to the atomic ioctl. Changes since v3: - Fix copyright on year. (Adrinael) - Use do_ioctl instead of do_or_die(igt_ioctl) (ickle). - Add test description.
