I think this is a really good v1 version of dma_buf. It contains all the required bits (with well-specified semantics in the doc patch) to implement some basic use-cases and start fleshing out the integration with various subsystem (like drm and v4l). All the things still under discussion like
- userspace mmap support
- more advanced (and more strictly specified) coherency models
- and shared infrastructure for implementing exporters
are imo much clearer once we have a few example drivers at hand and a better understanding of some of the insane corner cases we need to be able to handle.
And I think any risk that the resulting clarifications will break a basic use-case is really minimal, so I think it'd be great if this could go into 3.3 (maybe as some kind of staging/experimental infrastructure).
Hence for both patches: Reviewed-by: Daniel Vetter daniel.vetter@ffwll.ch
Yeah I'm with Daniel, I like this one, I can definitely build the drm buffer sharing layer on top of this.
How do we see this getting merged? I'm quite happy to push it to Linus if we don't have an identified path, though it could go via a Linaro tree as well.
so feel free to add: Reviewed-by: Dave Airlie airlied@redhat.com
Thanks Daniel and Dave!
I guess we can start with staging for 3.3, and see how it shapes up. I will post the latest patch version pretty soon.
Arnd, Dave: do you have any preference on the path it takes to get merged? In my mind, Linaro tree might make more sense, but I would leave it upto you gentlemen.
Dave.
