From cb6ab17d1fffe2f387ce4ec7691f926260091118 Mon Sep 17 00:00:00 2001 From: Samuel Pitoiset Date: Mon, 13 Apr 2020 11:38:33 +0200 Subject: [PATCH] radv: add radeon_set_context_reg_rmw() helper For emitting RMW packets in the command stream. This new helper will be useful for implementing extended dynamic states to only overwrite the fields that need to be updated instead of storing more values in the pipeline.
