This patch series switch assignment to igt_assign_pipes_for_outputs() and map outputs by their driving CRTC/pipe. Skip outputs that cannot be assigned and continue when at least one output is valid. Store highest_mode as owned copies to avoid stale connector mode pointers after output refresh. Iterate stress/setup by assigned pipe(output_by_pipe) instead of connected-output order. Keep progressive modeset flow by clearing temporary CRTC mappings after assignment. Use min_t(int, ...) for source size calculations to start scaling from a size guaranteed to fit in the FB. *** BLURB HERE *** Sowmiya S (2): tests/kms_pipe_stress: make pipe assignment joiner-aware tests/meson.build: Join header file tests/intel/kms_pipe_stress: Clamp the source size to the FB bounds tests/intel/kms_pipe_stress.c | 209 ++++++++++++++++++---------------- tests/meson.build | 1 + 2 files changed, 110 insertions(+), 100 deletions(-) -- 2.48.1
