linux.git/drivers/net/netdevsim/ethtool.c, branch v6.12.80 Clone of https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git net: Add struct kernel_ethtool_ts_info 2024-07-15T15:02:26+00:00 Kory Maincent kory.maincent@bootlin.com 2024-07-09T13:53:38+00:00 2111375b85ad173d58e7b8604246a3de60950ac8 In prevision to add new UAPI for hwtstamp we will be limited to the struct ethtool_ts_info that is currently passed in fixed binary format through the ETHTOOL_GET_TS_INFO ethtool ioctl. It would be good if new kernel code already started operating on an extensible kernel variant of that structure, similar in concept to struct kernel_hwtstamp_config vs struct hwtstamp_config. Since struct ethtool_ts_info is in include/uapi/linux/ethtool.h, here we introduce the kernel-only structure in include/linux/ethtool.h. The manual copy is then made in the function called by ETHTOOL_GET_TS_INFO.

In prevision to add new UAPI for hwtstamp we will be limited to the struct
ethtool_ts_info that is currently passed in fixed binary format through the
ETHTOOL_GET_TS_INFO ethtool ioctl. It would be good if new kernel code
already started operating on an extensible kernel variant of that
structure, similar in concept to struct kernel_hwtstamp_config vs struct
hwtstamp_config.

Since struct ethtool_ts_info is in include/uapi/linux/ethtool.h, here
we introduce the kernel-only structure in include/linux/ethtool.h.
The manual copy is then made in the function called by ETHTOOL_GET_TS_INFO.

netdevsim: report stats by default, like a real device 2024-04-08T10:40:41+00:00 Jakub Kicinski kuba@kernel.org 2024-04-05T02:45:24+00:00 f216306bfb602b449cb2c49cf03870fb8761d146 Real devices should implement qstats. Devices which support pause or FEC configuration should also report the relevant stats. nsim was missing FEC stats completely, some of the qstats and pause stats required toggling a debugfs knob. Note that the tests which used pause always initialize the setting so they shouldn't be affected by the different starting value.

net: netdevsim: use mock PHC driver 2023-08-09T22:59:21+00:00 Vladimir Oltean vladimir.oltean@nxp.com 2023-08-07T19:33:20+00:00 b63e78fca889e07931ec8f259701718a24e5052e I'd like to make netdevsim offload tc-taprio, but currently, this Qdisc emits a ETHTOOL_GET_TS_INFO call to the driver to make sure that it has a PTP clock, so that it is reasonably capable of offloading the schedule.

netdevsim: don't overwrite read only ethtool parms 2021-12-11T05:23:05+00:00 Filip Pokryvka fpokryvk@redhat.com 2021-12-10T17:50:32+00:00 ee60e626d536da4c710b3634afe68fe7c6d69b59 Ethtool ring feature has _max_pending attributes read-only. Set only read-write attributes in nsim_set_ringparam. This patch is useful, if netdevsim device is set-up using NetworkManager, because NetworkManager sends 0 as MAX values, as it is pointless to retrieve them in extra call, because they should be read-only. Then, the device is left in incosistent state (value > MAX).
