From: Mahesh Kumar <mahesh1.ku...@intel.com>
PIPEC doesnt have 3rd plane in GEN9. So, we skip the
3rd plane related scaling test where 2nd OVERLAY
plane is not available.
Restricting downscaling to (9/10)x original size of the
image to avoid "Max pixel rate limitation" of the hardware.
When testing with a resolution of 1024x768, the test fails
in iterate_plane_scaling because height becomes out of bounds.
Lastly, instead of a fixed test image, generate a test pattern
at runtime to not run into bxt's hardware limits for scaling.
Later patches in this series will cover corner cases of
scaling.
Changes since v1:
- Move out the code reshuffle to a separate commit. (Maarten)
This makes it more clear what's fixed.
Changes since v2:
- Fix iterate_plane_scaling on 1024x768. (Maarten)
- Instead of upscaling a test image, use the test pattern with a color.
(Maarten)
Using a 600x600 test pattern doesn't run into BXT's
hardware limits for scaling.
