From: Hsiao Chien Sung <[email protected]>
Set DRM mode configs limitation according to the hardware capabilities
and pass the IGT checks as below:
- The test "graphics.IgtKms.kms_plane" requires a frame buffer with
width of 4512 pixels (> 4096).
- The test "graphics.IgtKms.kms_cursor_crc" checks if the cursor size is
defined, and run the test with cursor size from 1x1 to 512x512.
Please notice that the test conditions may change as IGT is updated.

I would like to be different line:
int min_width;
int min_height;
