From 22ac1f692228d8c44155bfa637c8e34356c7e0b7 Mon Sep 17 00:00:00 2001 From: Francisco Jerez Date: Wed, 23 Dec 2015 18:44:59 +0200 Subject: [PATCH] i965: Add state bit to trigger re-emission of color calculator state. This will be used on Gen8+ to make sure that the color calculator state pointers are re-emitted when switching back to the 3D pipeline after some GPGPU workload due to a hardware workaround. There are other state bits already defined that could be used to achieve the same effect but they all cause a ton of unrelated state to be re-emitted (e.g. BRW_NEW_STATE_BASE_ADDRESS), so just define a new one, state bits are cheap.
