Version 2 of EGL_KHR_gl_image support. The changes addressed the comments from
Eric Anholt in intel_setup_image_from_mipmap_tree().
The previous implementation had a potential for orphaning EGL images when we
overwrite the original miptree for non-tile-aligned surfaces in order to obtain
corrected offsets back to our exported image. In this version, for
non-tile-aligned
surfaces, we copy the image to a temporary single-level miptree and refer to
the
offsets there instead of re-creating the whole miptree from scratch.
Tested on: Gen4, SandyBridge, IvyBridge
Abdiel Janulgue (6):
dri2: Create image from texture
intel: create a miptree for a region based on an offset, size, and level.
intel: add new miptree helper functions
i965: Account for offsets when emitting SURFACE_STATE.
intel: implement create image from texture
intel: Create a miptree using offsets in intel_set_texture_image_region
