CONFIG_GPIO_SLOPPY_LOGIC_ANALYZER: Sloppy GPIO logic analyzer

General informations

The Linux kernel configuration item CONFIG_GPIO_SLOPPY_LOGIC_ANALYZER:

• prompt: Sloppy GPIO logic analyzer
• type: tristate
• depends on: ( CONFIG_GPIOLIB || CONFIG_COMPILE_TEST ) && CONFIG_CPUSETS && CONFIG_DEBUG_FS && CONFIG_EXPERT
• defined in drivers/gpio/Kconfig
• found in Linux kernels: 6.11-rc+HEAD
• modules built: gpio-sloppy-logic-analyzer

Help text

This option enables support for a sloppy logic analyzer using polled GPIOs. Use the 'tools/gpio/gpio-sloppy-logic-analyzer' script with this driver. The script will make it easier to use and will also isolate a CPU for the polling task. Note that this is a last resort analyzer which can be affected by latencies, non-deterministic code paths, or NMIs. However, for e.g. remote development, it may be useful to get a first view and aid further debugging.

If this driver is built as a module it will be called 'gpio-sloppy-logic-analyzer'.
