In this IGT, various scaling modes are validated. Scaling
mode is one of the connector properties. This property
defines how a non-native mode is upscaled to the native
mode of an LCD panel.
There are 4 types of scaling modes defined:
None:
No upscaling happens, scaling is left to the panel. Not all
drivers expose this mode.
Full:
The output is upscaled to the full resolution of the panel,
ignoring the aspect ratio. It will expand current image to
the size of the monitor.
Center:
No upscaling happens, the output is centered within the native
resolution the panel. As a result, black bars may appear
around the image.
Full aspect:
The output is upscaled to maximize either the width or height
while retaining the aspect ratio. It will fill the screen w/o
stretching the image. Black bars are placed either on top
and bottom or left and right of the picture.
v2: -removed test flags/test_cycle_flags() (JP)
-removed redundant igt_display_commit_atomic() (JP)
-corrected indentation (JP)
v3: -removed valid_test check, getting covered in
igt_subtest_with_dynamic() (Bhanu)
-removed redundant if statement, moved remove_fb()
before skip (JP)
v4: -Removed unnecessary headers (JP)
-Corrected usage of igt_dynamic_f() (Bhanu)
