Subject: vk/image: Add anv_image::h_align,v_align
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=e6162c2feff6dee48cd5c1e99e2fe70b5ce07f9f;p=mesa.git

vk/image: Add anv_image::h_align,v_align

Use the new fields to compute RENDER_SURFACE_STATE.Surface*Alignment.
We still hardcode them to 4, though.
