From: Chad Versace Date: Mon, 8 Apr 2013 20:45:49 +0000 (-0700) Subject: intel: Replace checks for hiz_mt with intel_has*hiz() X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=2d3bbc576c095f0942d131db886f5661dec5680c;p=mesa.git intel: Replace checks for hiz_mt with intel_has*hiz() When appropriate, replace each check `hiz_mt != NULL` with either a call to intel_miptree_slice_has_hiz() or intel_renderbuffer_has_hiz(). No behavioral change. This prepares for selectively enabling hiz on individual miptree slices for Haswell. This refactoring had several side effects. 1. To prevent new warnings about discarding the const qualifier, I removed 'const' from some variable declarations in intel_validate_framebuffer(). The alternative was to add const qualifiers to multiple function signatures in the intel_renderbuffer_has_hiz call graph. Since the dominant convention in the Intel code is to not qualify function parameters as const, I chose to remove rather than add const qualifiers. 2. I changed the signature of brw_emit_depth_stencil_hiz() by replacing `struct intel_mipmap_tree *hiz_mt` with `bool hiz`. The function used hiz_mt mostly as a boolean indicator of the presence of hiz, so the signature change is consistent with the patch's goal.
