[Intel-gfx] [PATCH i-g-t 1/2] Prep work for adding NV12 testcase
Chandra Konduru
chandra.konduru at intel.com
Wed Aug 19 18:05:24 PDT 2015
From: chandra konduru <chandra.konduru at intel.com>
This patch adds necessary prep work for nv12 testcase:
- updated fb allocation functions to handle NV12 format
- igt helper function to return png image size
- igt helper function to calculate start of uv in a given NV12 buffer
- igt helper function to map buffer for host access
- populates fb->...[4] parameters for NV12
- igt helper function to convert RGB data to NV12
- updated drm_format to bpp to handle NV12
- updated fast copy blit function to deal NV12 subplanes
- made an update to kms_render testcase due to above changes
