Subject: vk/image: Factor view creation out into separate *_init functions
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=4668bbb16140816138366410ec28357ab5a43a39;p=mesa.git

vk/image: Factor view creation out into separate *_init functions

The *_init functions work basically the same as the Vulkan entrypoints
except that they act on an already-created view and take an optional
command buffer option.  If a command buffer is given, the surface state is
allocated out of the command buffer's state stream.
