From ea783667e4fff16fde9dfb76eefcd6aa484077d4 Mon Sep 17 00:00:00 2001 From: Dave Airlie Date: Tue, 7 Jun 2016 15:25:56 +1000 Subject: [PATCH] mesa: add api to write subroutine indicies to the program storage. This writes the subroutine indicies to the program storage for a stage. This API is intended to be used by drivers to update the uniform storage before uploading to the hw. This isn't the most thread safe effort, but it will be significantly more multi-context safe.
