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
