+Extend virtual test driver (VKMS)
+---------------------------------

+See the documentation of :ref:`VKMS <vkms>` for more details. This is an ideal
+internship task, since it only requires a virtual machine and can be sized to
+fit the available time.

+
+CRC API
+-------
+
+- Optimize CRC computation ``compute_crc()`` and plane blending ``blend()``
+
+- Use the alpha value to blend vaddr_src with vaddr_dst instead of
+ overwriting it in ``blend()``.
+
+- Add igt test to check cleared alpha value for XRGB plane format.
+
+- Add igt test to check extreme alpha values i.e. fully opaque and fully
+ transparent (intermediate values are affected by hw-specific rounding modes).
