The current implementation of the mark_victim tracepoint provides only
the process ID (pid) of the victim process. This limitation poses
challenges for userspace tools that need additional information
about the OOM victim. The association between pid and the additional
data may be lost after the

It is now possible to mmap() a ring-buffer to stream its content. Add
some documentation and a code example.

Currently, user-space extracts data from the ring-buffer via splice,
which is handy for storage or network sharing. However, due to splice
limitations, it is imposible to do real-time analysis without a copy.
A solution for that problem is to let the user-space map the ring-buffer
directly.

The tracing ring-buffers can be stored on disk or sent to network
without any copy via splice. However the later doesn't allow real time
processing of the traces. A solution is to give userspace direct access
to the ring-buffer pages via a mapping. An application can now become a
consumer of the

Hi Aiswarya,
I was looking into VirtIO audio controls support in Linux and came across this
patch series, which seems to be marked "archived" on patchwork [0]. I would
love to be able to use this with mainline Linux. I'm wondering about the status
of this series - is the feature still under

Hi!
