[igt-dev] [PATCH i-g-t 0/5] lib/igt_kms: Add for_each_pipe_with_single_output and igt_get_single_output_for_pipe.

[Maarten Lankhorst]

Some tests don't have to be called on all outputs, because they only manipulate the pipe.
For these tests we create 2 helper functions, so we reduce the amount of modesets required.

for_each_pipe_with_single_output is a drop in replacement for for_each_pipe_with_valid_output,
and only iterates 1 output per pipe.

igt_get_single_output_for_pipe returns a valid output for a given pipe, if it can be found.
It can be used in place of a for_each_valid_output_on_pipe loop.

This is just a sample conversion, other tests can be changed when this is accepted..

Maarten Lankhorst (5):
  lib/igt_kms: Add functions to get only a single output for a pipe.
  tests/kms_rmfb: Use for_each_pipe_with_single_output.
  tests/kms_busy: Convert to using igt_get_single_output_for_pipe.
  tests/kms_chv_cursor_fail: Reorder tests, and use
    igt_display_require_output_on_pipe.
  tests/kms_chv_cursor_fail: Handle cleanup better.
