From 9f162fa10749fe4ed3dd59d320852e1476420be6 Mon Sep 17 00:00:00 2001 From: "Wladimir J. van der Laan" Date: Sat, 18 Nov 2017 10:44:25 +0100 Subject: [PATCH] etnaviv: Put HALTI level in specs The HALTI level is an indication of the gross architecture of the GPU. It determines for significant part what feature level the GPU has, what state (especially frontend state) is there, and where it is located.
