From 075d9eafdb4c1c64099d738a012fe3e063f08fee Mon Sep 17 00:00:00 2001 From: Matt Roper Date: Mon, 30 Jun 2014 16:44:28 -0700 Subject: tests/kms_universal_plane: Universal plane testing (v6) Add a simple test to exercise universal plane support. v6: - Update to new universal plane interface (commit parameter rather than state-changing function). It should now be a lot more explicit which steps are being taken with legacy API's vs universal API's now. v5: - Check that we don't have more than one primary or cursor. This will catch accidental calls to drm_plane_init() in the kernel where drm_universal_plane_init() was intended (these don't cause a compile warning due to type compatibility between enum and bool). v4: - Test disabling the primary plane explicitly when it has previously been implicitly disabled due to clipping. - Skip test if igt_pipe_crc_new() fails v3: - For testing while crtc is off, switch between several different primary plane fb's before reenabling the crtc. This will help catch pin/unpin mistakes. v2: - Test that pageflips error out gracefully when the primary plane is disabled before the ioctl, or between ioctl and pageflip execution. - Test that nothing blows up if we try to disable the primary plane immediately after a pageflip (presumably before the pageflip actually completes). - Test that we can setup primary + sprite planes with the CRTC off and then have them show up properly when we enable the CRTC (drmModeSetCrtc with fb = -1). - Test that we can modeset properly after having disabled the primary plane - Test that proper error codes are returned for invalid plane programming attempts.
