Subject: [RFC 0/7] drm: Add shmem GEM library
Date: Wed, 12 Jul 2017 15:45:58 +0200 [thread overview]
Message-ID: <1499867165-60925-1-git-send-email-noralf@tronnes.org> (raw)
This patchset adds a library for shmem backed GEM objects.
I'm putting out an rfc to find out if I'm on the right track with this.
The shmem library is very similar to the cma library, so I have tried
to pull out the common bits.
A couple of questions:
- What should the default cache mode be?
- Do I need locking around vmap/vunmap?
See TODO in [RFC 5/7] drm: Add library for shmem backed GEM objects
Noralf.
Noralf Trønnes (7):
drm/gem: Add drm_gem_dumb_map_offset()
drm: Add GEM backed framebuffer library
drm/fb-helper: Support shadow buffer with deferred io
drm/fb-helper: Add simple init/fini functions
drm: Add library for shmem backed GEM objects
drm: Add kms library for shmem backed GEM
drm/tinydrm: Switch from CMA to shmem buffers
