Subject: [PATCH 00/22] drm/dma-helper: Add dedicated fbdev emulation
Date: Wed, 1 Mar 2023 16:30:39 +0100 [thread overview]
Message-ID: <20230301153101.4282-1-tzimmermann@suse.de> (raw)
Add fbdev emulation that is optimized for DMA helpers, as used by most
drivers. It operates directly on GEM DMA buffers in system memory.
Memory pages are mmap'ed directly to userspace. No implicit shadow
buffers need to be allocated; as can happen with the generic fbdev
emulation. Convert drivers that fulfil the requirements.
Tested with fbcon and IGT on vc4.
Future direction: providing a dedicated fbdev emulation for GEM DMA
helpers will allow us to remove this case from the generic fbdev code.
The latter can then be simplified.
