Subject: [PATCH net-next v2 0/6] ice: lower CPU usage with GNSS
Date: Wed, 12 Apr 2023 10:19:23 +0200 [thread overview]
Message-ID: <20230412081929.173220-1-mschmidt@redhat.com> (raw)
This series lowers the CPU usage of the ice driver when using its
provided /dev/gnss*.
v2:
- Changed subject of patch 1. Requested by Andrew Lunn.
- Added patch 2 to change the polling interval as recommended by Intel.
- Added patch 3 to remove sq_cmd_timeout as suggested by Simon Horman.
Michal Schmidt (6):
ice: do not busy-wait to read GNSS data
ice: increase the GNSS data polling interval to 20 ms
ice: remove ice_ctl_q_info::sq_cmd_timeout
ice: sleep, don't busy-wait, for ICE_CTL_Q_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
