We don't have access to the kernel's curr_clocksource variable, so just
make a general statement.

The `user_msghdr' structure is designed to send multiple messages as
well, so rtcan_raw_sendmsg() can also send multiple messages. This
avoids having to add the sendmmsg system call which requires more
extensive Xenomai changes.

Bosch C_CAN controller is a full-CAN implementation which is compliant
to CAN protocol version 2.0 part A and B.
Starting from the RTDM porting [1] by Stephen Battazzo, Michael applied
some fixes for proper driver operation. Then I ported the commits from
Linux kernel version 5.12 and finally I ad

Like in the Linux kernel, the API allows to get/set device controller
parameters.
For now it only supports:
- ETHTOOL_GDRVINFO: get general driver and device information
- ETHTOOL_GRINGPARAM: get RX/TX ring parameters
It allows the userspace to know the number of messages managed by the

As mentioned in Linux, can_dlc is a misleading name that suggests a code

Hi Jan
What about following patch? Try to get clocksource name via sys fs.

For dovetail-based, handle_oob_trap_entry would try to demote oob
stage and leave in-band to do panic thing when fault happen.

Some of the features are unportable because ftrace does not
provide equivalent functionality to the ipipe tracer (namely double
buffering so that you can continue to record in flight-recorder mode
while a previous recording remains available).
