menuconfig SAMPLES
bool "Sample kernel code"
help
You can build and test sample kernel code here.
if SAMPLES
config SAMPLE_AUXDISPLAY
bool "auxdisplay sample"
depends on CC_CAN_LINK
config SAMPLE_TRACE_EVENTS
tristate "Build trace_events examples -- loadable modules only"
depends on EVENT_TRACING && m
help
This builds the trace event example module.
config SAMPLE_TRACE_CUSTOM_EVENTS
tristate "Build custom trace event example -- loadable modules only"
depends on EVENT_TRACING && m
help
This builds the custom trace event example module.
config SAMPLE_TRACE_PRINTK
tristate "Build trace_printk module - tests various trace_printk formats"
depends on EVENT_TRACING && m
help
This builds a module that calls trace_printk() and can be used to
test various trace_printk() calls from a module.
config SAMPLE_FTRACE_DIRECT
tristate "Build register_ftrace_direct() example"
depends on DYNAMIC_FTRACE_WITH_DIRECT_CALLS && m
depends on HAVE_SAMPLE_FTRACE_DIRECT
help
This builds an ftrace direct function example
that hooks to wake_up_process and prints the parameters.
config SAMPLE_FTRACE_DIRECT_MULTI
tristate "Build register_ftrace_direct() on multiple ips example"
depends on DYNAMIC_FTRACE_WITH_DIRECT_CALLS && m
depends on HAVE_SAMPLE_FTRACE_DIRECT_MULTI
help
This builds an ftrace direct function example
that hooks to wake_up_process and schedule, and prints
the function addresses.
config SAMPLE_FTRACE_OPS
tristate "Build custom ftrace ops example"
depends on FUNCTION_TRACER
help
This builds an ftrace ops example that hooks two functions and
measures the time taken to invoke one function a number of times.
config SAMPLE_TRACE_ARRAY
tristate "Build sample module for kernel access to Ftrace instances"
depends on EVENT_TRACING && m
help
This builds a module that demonstrates the use of various APIs to
access Ftrace instances from within the kernel.
config SAMPLE_KOBJECT
tristate "Build kobject examples"
help
This config option will allow you to build a number of
different kobject sample modules showing how to use kobjects,
ksets, and ktypes properly.
If in doubt, say "N" here.
Annotation
- Atlas domain: Support Tooling And Documentation / samples.
- Implementation status: atlas-only.
Implementation Notes
- This generated page is the file-by-file coverage layer; curated subsystem chapters should link here when they synthesize a multi-file control flow.
- Core OS pages should be promoted from atlas-only to deep-reviewed when they explain data structures, invariants, locking, lifecycle, and C implementation snippets.
- Driver-family pages are intentionally pattern-oriented unless they are part of the selected PCIe/NVMe representative device path.
