From 81900e3a37750d8c6ad705045310e002f6dd0356 Mon Sep 17 00:00:00 2001 From: Lionel Landwerlin lionel.g.landwerlin@intel.com Date: Fri, 7 Apr 2023 12:32:37 +0300 Subject: [PATCH] drm/i915: disable sampler indirect state in bindless heap

By default the indirect state sampler data (border colors) are stored in the same heap as the SAMPLER_STATE structure. For userspace drivers that can be 2 different heaps (dynamic state heap & bindless sampler state heap). This means that border colors have to copied in 2 different places so that the same SAMPLER_STATE structure find the right data.

This change is forcing the indirect state sampler data to only be in the dynamic state pool (more convenient for userspace drivers, they only have to have one copy of the border colors). This is reproducing the behavior of the Windows drivers.
