Hi Greg, There are the updates for the Intel TH driver that I have for the next cycle. These are multi-window mode buffer management changes, mainly to add support for software trace sinks.
One patch at the top is a dependency, from a pull request I sent last week with fixes for v5.2 [1]. Individual patches are in follow-up emails, a signed tag is also pushed out and available at the URL below. Please consider pulling or applying. Thanks!
