From: Chad Versace Date: Fri, 5 Apr 2013 22:18:00 +0000 (-0700) Subject: intel: Allocate hiz in intel_renderbuffer_move_to_temp() X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=aa391976dfa12479185d9eeed1f2a0b4dce6c49b;p=mesa.git intel: Allocate hiz in intel_renderbuffer_move_to_temp() When moving the renderbuffer to a new miptree, we neglected to allocate the hiz buffer for the new miptree. Oops. Fixes all Piglit depthstencil-render-miplevels tests from crash to pass on Sandybridge. Note: This is a candidate for the 9.1 branch.
