* machine/stdarg.h -> sys/stdarg.hBrooks Davis2025-06-111-1/+1
| | | | | | | | | | | | | Switch to using sys/stdarg.h for va_list type and va_* builtins. Make an attempt to insert the include in a sensible place. Where style(9) was followed this is easy, where it was ignored, aim for the first block of sys/*.h headers and don't get too fussy or try to fix other style bugs.

* dtrace/profile: Stop storing the probe name in struct profile_probeMark Johnston2025-06-041-2/+0

* dtrace/profile: Set t_dtrace_trapframe for profile probesMark Johnston2024-01-071-1/+6
| | | | | | | | | | profile provider probes fire in the context of a timer interrupt. Thus, the "regs" action can make use of the interrupt trap frame to get register values when the interrupt happened in kernel mode. Make that trap frame available when possible so that "regs" works more or less as it already does with the fbt and kinst providers. MFC after: 1 week

* Merge OpenZFS support in to HEAD.Matt Macy2020-08-251-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The primary benefit is maintaining a completely shared code base with the community allowing FreeBSD to receive new features sooner and with less effort. I would advise against doing 'zpool upgrade' or creating indispensable pools using new features until this change has had a month+ to soak. Work on merging FreeBSD support in to what was at the time "ZFS on Linux" began in August 2018. I first publicly proposed transitioning FreeBSD to (new) OpenZFS on December 18th, 2018. FreeBSD support in OpenZFS was finally completed in December 2019. A CFT for downstreaming OpenZFS support in to FreeBSD was first issued on July 8th. All issues that were reported have been addressed or, for a couple of less critical matters there are pull requests in progress with OpenZFS. iXsystems has tested and dogfooded extensively internally. The TrueNAS 12 release is based on OpenZFS with some additional features that have not yet made it upstream. Improvements include: project quotas, encrypted datasets, allocation classes, vectorized raidz, vectorized checksums, various command line improvements, zstd compression. Thanks to those who have helped along the way: Ryan Moeller, Allan Jude, Zack Welch, and many others. Sponsored by: iXsystems, Inc.

In this case, provide a representative value, &cpu_idle, instead of 0 for args[0] so that the active thread can be more easily identified from the probe.

This appears to work quite well in practice on the BeagleBone Black, so remove a comment about the value being bogus and replace it with a slightly less negative one. However, the number of frames to skip is quite sensitive to details of the timer and interrupt handling paths, so this is necessarily fragile -- but no more so than on x86.
