Subject: [Intel-wired-lan] [PATCH net-next 0/4] ice: lower CPU usage with GNSS
Date: Sat, 1 Apr 2023 19:26:55 +0200 [thread overview]
Message-ID: <20230401172659.38508-1-mschmidt@redhat.com> (raw)
This series lowers the CPU usage of the ice driver when using its
provided /dev/gnss*.
Intel engineers, in addition to reviewing the patches for correctness,
please also consider my doubts expressed in the descriptions of patches
1 and 2. There may be better solutions possible.
Michal Schmidt (4):
ice: lower CPU usage of the GNSS read thread
ice: sleep, don't busy-wait, for sq_cmd_timeout
ice: remove unused buffer copy code in ice_sq_send_cmd_retry()
ice: sleep, don't busy-wait, in the SQ send retry loop
