These are rather simple. Without the capability of creating
textures out of the images (glEGLImageTargetTexture2DOES()), one
cannot do much with the images as such.
In the tests I've chosen the approach where the creator releases
its own references to the buffers even though the EGL stack closes
the file descriptors used for buffer exporting.
v2:
- use 'struct piglit_dma_buf *' instead of 'void *'
- use ARRAY_SIZE
- clarified the contents of the missing attributes test vector
- clarified the re-using of the buffer in case of:
tests/spec/ext_image_dma_buf_import/invalid_attributes.c
tests/spec/ext_image_dma_buf_import/invalid_hints.c
tests/spec/ext_image_dma_buf_import/missing_attributes.c
Old text:
* "If <target> is EGL_LINUX_DMA_BUF_EXT and eglCreateImageKHR fails,
* EGL does not retain ownership of the file descriptor and it is the
* responsibility of the application to close it."
New text:
* One re-uses the buffer for all the tests. Each test is expected to
* fail meaning that the ownership is not transferred to the EGL in
* any point.
- clarified the 'close_buffer'-test by:
"Here on checks that the creator of the buffer can drop its reference once
it has given the buffer to EGL, i.e., after calling 'eglCreateImageKHR()'"
The test also now checks that 'eglDestroyImageKHR()' does not generate any
error.
- added test for context other than 'EGL_NO_CONTEXT'
- added test for sampling ARGB8888
- added test for sampling XRGB8888
- added test for sampling ARGB8888 without other mip-levels being present
v3:
- added test for YUV420 having all planes in the same buffer
- modified the tests to close the file descriptors whenever EGL does not
take the ownership
