- Add cgroup support for rtla via the -C option - Add --house-keeping option that tells rtla where to place the housekeeping threads. - Have rtla/timerlat have its own tracing instance instead of using the top level tracing instance that is the default for other tracing users to use. - Add auto analysis to timerlat_hist - Have rtla start the tracers after creating the instances - Reduce rtla hwnoise down to 75% from 100% as it runs with preemption disabled and can cause system instability at 100%. - Add support to run timerlat_top and timerlat_hist threads in user-space instead of just using the kernel tasks. - Some minor clean ups and documentation changes. -----BEGIN PGP SIGNATURE----- iIoEABYIADIWIQRRSw7ePDh/lE+zeZMp5XQQmuv6qgUCZKQazxQccm9zdGVkdEBn b29kbWlzLm9yZwAKCRAp5XQQmuv6qn+kAP4uksUlaic1j4eB44pJCdVuia7+WT5N LNwAyOqcupKlRwD9GDjLZf4JgnHkHHFgFmVts3UTQmKmL71YkTTc3aXdVw8= =CC6L -----END PGP SIGNATURE----- Merge tag 'trace-tools-v6.5' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull tracing tooling updates from Steven Rostedt: - Add cgroup support for rtla via the -C option - Add --house-keeping option that tells rtla where to place the housekeeping threads - Have rtla/timerlat have its own tracing instance instead of using the top level tracing instance that is the default for other tracing users to use - Add auto analysis to timerlat_hist - Have rtla start the tracers after creating the instances - Reduce rtla hwnoise down to 75% from 100% as it runs with preemption disabled and can cause system instability at 100% - Add support to run timerlat_top and timerlat_hist threads in user-space instead of just using the kernel tasks - Some minor clean ups and documentation changes * tag 'trace-tools-v6.5' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: Documentation: Add tools/rtla timerlat -u option documentation rtla/timerlat_hist: Add timerlat user-space support rtla/timerlat_top: Add timerlat user-space support rtla/hwnoise: Reduce runtime to 75% rtla: Start the tracers after creating all instances rtla/timerlat_hist: Add auto-analysis support rtla/timerlat: Give timerlat auto analysis its own instance rtla: Automatically move rtla to a house-keeping cpu rtla: Change monitored_cpus from char * to cpu_set_t rtla: Add --house-keeping option rtla: Add -C cgroup support
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
