Hi Jonathan,
Here's the final(tm) version of the IIO DMABUF patchset.
This v8 fixes the remaining few issues that Christian reported.
I also updated the documentation patch as there has been changes to index.rst.
This was based on next-20240308.
Changelog:
- [3/6]:
- Fix swapped fence direction
- Simplify fence wait mechanism
- Remove "Buffer closed with active transfers" print, as it was dead code
- Un-export iio_buffer_dmabuf_{get,put}. They are not used anywhere else so they can even be static.
- Prevent attaching already-attached DMABUFs
- [6/6]: Renamed dmabuf_api.rst -> iio_dmabuf_api.rst, and updated index.rst whose format changed in iio/togreg.
Cheers, -Paul
Given nature of the build bug issues reported, I'm guessing you never built this as a module :( Not sure how one instance of a missing user marking got through but also easy to fix.
Anyhow, no need to wait before sending a v9 with those sorted.
0-day does it's job again - even better is that it's whilst it's still your problem and not mine :)
