| H A D | vkms_composer.c | diff 1ce76fae2bc14dd776b0c237456d8bd117c0e617 Tue Apr 18 08:05:23 CDT 2023 Maíra Canal <mcanal@igalia.com> drm/vkms: add reflect-y and rotate-180 property
Currently, vkms only supports the reflect-x property. Therefore, add the
reflect-y property to vkms through a software implementation of the
operation. This is possible by reverse reading the y axis during the
blending.
Note that, by implementing the reflect-x and reflect-y properties, it is
also possible to add the rotate-180 property, as it is a combination
of those two properties.
Tested with igt@kms_rotation_crc@primary-reflect-y [1],
igt@kms_rotation_crc@sprite-reflect-y [1],
igt@kms_rotation_crc@primary-rotation-180,
igt@kms_rotation_crc@sprite-rotation-180,
and igt@kms_rotation_crc@cursor-rotation-180.
