From c76f0f7cb546b661b5e0ac769850a5c854927f65 Mon Sep 17 00:00:00 2001 From: Noralf Trønnes Date: Tue, 3 Jul 2018 18:03:47 +0200 Subject: drm: Begin an API for in-kernel clients MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This the beginning of an API for in-kernel clients. First out is a way to get a framebuffer backed by a dumb buffer. Only GEM drivers are supported. The original idea of using an exported dma-buf was dropped because it also creates an anonomous file descriptor which doesn't work when the buffer is created from a kernel thread. The easy way out is to use drm_driver.gem_prime_vmap to get the virtual address, which requires a GEM object. This excludes the vmwgfx driver which is the only non-GEM driver apart from the legacy ones. A solution for vmwgfx will have to be worked out later if it wants to support the client API which it probably will when we have a bootsplash client.
