From: Jonathan Marek Date: Fri, 28 Jun 2019 02:02:45 +0000 (-0400) Subject: etnaviv: prep for UBOs X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=ee1ed59458741d36b217f80ebd83ffbd3426bf05;p=mesa.git etnaviv: prep for UBOs Allow UBO relocs and only emitting uniforms that are actually used. GC7000Lite has no address register, so upload uniforms to a UBO object to LOAD from. I removed the code to check for changes to individual uniforms and just reupload to entire uniform state when the state is dirty. I think there was very limited benefit to it and it isn't compatible with relocs.
