[Mesa-dev] [PATCH 10/15] anv/android: support creating images from external format
Tapani Pälli

Tue Nov 27 10:53:16 UTC 2018
Since we don't know the exact format at creation time, some initialization
is done only when bound with memory in vkBindImageMemory.
v2: demand dedicated allocation in vkGetImageMemoryRequirements2 if
image has external format
v3: refactor prepare_ahw_image, support vkBindImageMemory2,
calculate stride correctly for rgb(x) surfaces, rename as
'resolve_ahw_image'
v4: rebase to b43f955037c changes
