From 5bc3fcf620d428f9413623eee4e14ae753e35b2c Mon Sep 17 00:00:00 2001 From: Lucas Stach Date: Fri, 2 Aug 2019 14:53:08 +0200 Subject: [PATCH] etnaviv: check for softpin availability on Halti5 devices Halti5 uses texture descriptors to control the samplers, and thus needs to know the GPU virtual address for the texture buffers to fill into the descriptor buffer. Without softpin userspace has no control over the GPU VM and also no way to fix up the texture descriptor buffer, so there is no point in creating a screen on a Halti5 device without softpin being available.
