From 8cf8dfe408a7dda5121cefc2fd5d772186484f76 Mon Sep 17 00:00:00 2001 From: Gert Wollny Date: Sun, 7 Apr 2019 08:37:45 +0200 Subject: [PATCH] softpipe: Add an extra code path for the buffer texel lookup With buffers the addressing is done on a per-byte bases so the code path for normal textures doesn't work properly. Also add an assert to make sure that the bit cound for storing the X coordinate is large enough.
