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
