From eda73d71277a0dd9d7832da96c2aaca2dd513d4d Mon Sep 17 00:00:00 2001 From: "Wladimir J. van der Laan" Date: Sun, 29 Oct 2017 14:59:43 +0000 Subject: [PATCH] etnaviv: GC7000: Texture descriptors MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Create a separate implementation file with texture-descriptor-based sampler views and sampler states. Initialize the one or the other based on the GPU. There is so little in common that this seemed more appropriate that keeping them as one type of state object would only be confusing. This commit is actually a combiation of the original commit by Wladimir, fixes and TS implementation from Jonathan and changed to use softpin by Lucas.
