From 26e51e413be72256d4d416f8a9b9d04a78bfbf18 Mon Sep 17 00:00:00 2001 From: Philipp Zabel Date: Mon, 10 Apr 2017 11:15:52 +0200 Subject: [PATCH] etnaviv: sync uapi header Import the etnaviv header changes from kernel commits 9ad59fea162c ("drm/etnaviv: submit support for in-fences") and 78ec187f64fa ("drm/etnaviv: submit support for out-fences") for fence fd support. The drm_etnaviv_gem_submit structure was extended to include a flags field, new flags for in-fence and out-fence fds and an input/output fence fd field. This is one-way backwards compatible because old userspace code passing a short structure not including the flags field to new kernels will cause the remaining fields to be zero-filled. New userspace code must make sure to only pass the short structure to old kernels, though. Not generated using make headers_install, since the drm/etnaviv_drm.h uapi header is not installed yet by the kernel.
