+/**
+ * TEST: kms cursor crc
+ * Category: Display
+ * Description: Use the display CRC support to validate cursor plane functionality.
+ *              The test will position the cursor plane either fully onscreen,
+ *              partially onscreen, or fully offscreen, using either a fully
+ *              opaque or fully transparent surface. In each case, it enables
+ *              the cursor plane and then reads the PF CRC (hardware test) and
+ *              compares it with the CRC value obtained when the cursor plane
+ *              was disabled and its drawing is directly inserted on the PF by
+ *              software.
