Verbose user fault messages found in arch/arm/Kconfig.debug

The configuration item CONFIG_DEBUG_USER:

• prompt: Verbose user fault messages
• type: bool
• depends on: (none)
• defined in arch/arm/Kconfig.debug
• found in Linux kernels: 2.6.9–2.6.39, 3.0–3.19, 4.0–4.20, 5.0–5.19, 6.0–6.17, 6.18-rc+HEAD

Help text

When a user program crashes due to an exception, the kernel can print a brief message explaining what the problem was. This is sometimes helpful for debugging but serves no purpose on a production system. Most people should say N here.

In addition, you need to pass user_debug=N on the kernel command line to enable this feature. N consists of the sum of:

1 - undefined instruction events 2 - system calls 4 - invalid data aborts 8 - SIGSEGV faults 16 - SIGBUS faults
