This patchset adds generic fbdev emulation for drivers that supports GEM based dumb buffers which support .gem_prime_vmap and gem_prime_mmap. An API is begun to support in-kernel clients in general.
I've squashed the client patches to ease review. All patches have ack's and rb's so I'll apply this next week unless something more comes up. It's taken me 6 months to get this done so I look forward to getting it applied.
Thanks a lot Daniel for helping me make this happen!
Noralf.
Changes since version 4:
- Squash the two client patches to ease review.
- Remove drm_client_put() doc references.
- Remove drm_client_funcs->release, it's use went away in version 3.
- Add drm_client_dev_hotplug() doc
Changes since version 3:
- drm/cma-helper: Use the generic fbdev emulation: Fix error path
- Remove setting .lastclose in new tinydrm driver ili9341
Changes since version 2:
- Applied first 3 patches to drm-misc-next
- Drop client reference counting and only allow the driver to release
clients.
Quick aside: I like changelogs also in each patch (for the specific patch), avoids having to jump back&forth to see what's changed ... -Daniel
