Subject: [PATCH 0/4] thunderbolt: More improvements to USB4STREAM
Date: Tue,  8 Sep 2026 10:14:45 +0200	[thread overview]
Message-ID: <20260908081449.3424884-1-mika.westerberg@linux.intel.com> (raw)

Hi all,

Alan noticed that in certain workloads with concurrent reader and writer
the stream could stall for a while. These below improvements should make it
behave better in these cases.

Mika Westerberg (4):
  thunderbolt: Write descriptors in tb_ring_poll()
  thunderbolt: Add tb_ring_poll_pending()
  thunderbolt: stream: Do not hold the lock while busy polling
  thunderbolt: stream: Check the Rx ring before task starts sleeping
