From 08c9cc0d3dc7bdea948af7e85200ad5f4460b937 Mon Sep 17 00:00:00 2001 From: Paul Kocialkowski Date: Wed, 9 Jan 2019 17:55:59 +0100 Subject: lib/igt_fb: Add support for allocating T-tiled VC4 buffers This introduces the required bits for allocating buffers with a T-tiled disposition, that is specific to the VC4. It includes calculating the top-tile width and creating a buffer object with the VC4-specific helper. The tiling flag is set to the buffer object so that this can be reused for GPU tests if needed later.
