From e4f748c6e9d618eb2ee8f15aa22aae8dcde4cc4a Mon Sep 17 00:00:00 2001 From: Simon Ser Date: Wed, 24 Nov 2021 10:33:13 +0100 Subject: render/allocator: fallback to renderer DRM FD in autocreate If the backend doesn't have a DRM FD, fallback to the renderer's. This accomodates for the situation where the headless backend hasn't picked a DRM FD in particular, but the renderer has picked one. --- render/allocator/allocator.c | 3 +++ 1 file changed, 3 insertions(+) (limited to 'render/allocator/allocator.c') diff --git a/render/allocator/allocator.c b/render/allocator/allocator.c index 15d55a0d..5108ad04 100644 --- a/render/allocator/allocator.c +++ b/render/allocator/allocator.c @@ -139,6 +139,9 @@ struct wlr_allocator *wlr_allocator_autocreate(struct wlr_backend *backend, struct wlr_renderer *renderer) { // Note, drm_fd may be negative if unavailable int drm_fd = wlr_backend_get_drm_fd(backend); + if (drm_fd < 0) { + drm_fd = wlr_renderer_get_drm_fd(renderer); + } return allocator_autocreate_with_drm_fd(backend, renderer, drm_fd); } -- cgit v1.2.3
