From 23e9f06569f58062820ab058d8057e9325042105 Mon Sep 17 00:00:00 2001 From: Chris Forbes Date: Thu, 8 May 2014 17:06:01 +1200 Subject: i965/Gen8: Set up layer constraints properly for depth buffers Same issues as the previous commit fixed for Gen7: - Bogus physical->logical layer conversion; depth/stencil surfaces are still IMS layout on Gen8. - mt_layer ignored in layered rendering case, which breaks handling of views with MinLayer. - Render target array extent not set correctly for arrays. I'm not able to test this one since I can't get a Broadwell yet, but it's the same set of fixes as for Gen7. V2: Restore the MAX2() to account for zero depth/layer_count.
