tools/dma: move dma_map_benchmark from selftests to tools/dma

2025-10-29T08:41:40+00:00

dma_map_benchmark is a standalone developer tool rather than an automated selftest. It has no pass/fail criteria, expects manual invocation, and is built as a normal userspace binary. Move it to tools/dma/ and add a minimal Makefile.

sched_ext: Add scx_simple and scx_example_qmap example schedulers

2024-06-18T20:09:17+00:00

Add two simple example BPF schedulers - simple and qmap. * simple: In terms of scheduling, it behaves identical to not having any operation implemented at all. The two operations it implements are only to improve visibility and exit handling. On certain homogeneous configurations, this actually can perform pretty well. * qmap: A fixed five level priority scheduler to demonstrate queueing PIDs on BPF maps for scheduling. While not very practical, this is useful as a simple example and will be used to demonstrate different features. v7: - Compat helpers stripped out in prepartion of upstreaming as the upstreamed patchset will be the baselinfe. Utility macros that can be used to implement compat features are kept. - Explicitly disable map autoattach on struct_ops to avoid trying to attach twice while maintaining compatbility with older libbpf. v6: - Common header files reorganized and cleaned up. Compat helpers are added to demonstrate how schedulers can maintain backward compatibility with older kernels while making use of newly added features. - simple_select_cpu() added to keep track of the number of local dispatches. This is needed because the default ops.select_cpu() implementation is updated to dispatch directly and won't call ops.enqueue(). - Updated to reflect the sched_ext API changes. Switching all tasks is the default behavior now and scx_qmap supports partial switching when `-p` is specified. - tools/sched_ext/Kconfig dropped. This will be included in the doc instead. v5: - Improve Makefile. Build artifects are now collected into a separate dir which change be changed. Install and help targets are added and clean actually cleans everything. - MEMBER_VPTR() improved to improve access to structs. ARRAY_ELEM_PTR() and RESIZEABLE_ARRAY() are added to support resizable arrays in .bss. - Add scx_common.h which provides common utilities to user code such as SCX_BUG[_ON]() and RESIZE_ARRAY(). - Use SCX_BUG[_ON]() to simplify error handling. v4: - Dropped _example prefix from scheduler names. v3: - Rename scx_example_dummy to scx_example_simple and restructure a bit to ease later additions. Comment updates. - Added declarations for BPF inline iterators. In the future, hopefully, these will be consolidated into a generic BPF header so that they don't need to be replicated here. v2: - Updated with the generic BPF cpumask helpers.

tools/nolibc: make the default target build the headers

2022-06-20T16:43:19+00:00

The help in "make -C tools" enumerates nolibc as a valid target so we must at least make it do something. Let's make it do the equivalent of "make headers" in that it will prepare a sysroot with the arch's headers, but will not install the kernel's headers. This is the minimum some tools will need when built with a full-blown toolchain anyway. Signed-off-by: Willy Tarreau Signed-off-by: Paul E. McKenney

tools/thermal: Add thermal daemon skeleton

2022-05-19T10:11:52+00:00

This change provides a simple daemon skeleton. It is an example of how to use the thermal library which wraps all the complex code related to the netlink and transforms it into a callback oriented code. The goal of this skeleton is to give a base brick for anyone interested in writing its own thermal engine or as an example to rely on to write its own thermal monitoring implementation. In the future, it will evolve with more features and hopefully more logic.

tools/thermal: Add a temperature capture tool

2022-05-19T10:11:52+00:00

The 'thermometer' tool allows to capture the temperature of a set of thermal zones defined in a configuration file at a specified rate. It is designed to have the lowest possible overhead. It will write the captured temperature per thermal zone per file so making easier to write a gnuplot script.
