Hi,

As part of the ongoing rebase effort, the following configuration options need to be reviewed.

As a reminder, the ARK configuration flow involves moving unreviewed configuration options from the pending directory to the ark directory. In the diff below, options are removed from the pending directory and added to the ark hierarchy. The final options that need to be ACKed are the files that are being added to the ark hierarchy.

If the value for a file that is added should be changed, please reply with a better option.

CONFIG_KGDB_HONOUR_BLOCKLIST:

If set to Y the debug core will use the kprobe blocklist to identify symbols where it is unsafe to set breakpoints. In particular this disallows instrumentation of functions called during debug trap handling and thus makes it very difficult to inadvertently provoke recursive trap handling.

If unsure, say Y.

Symbol: KGDB_HONOUR_BLOCKLIST [=y] Type : bool Defined at lib/Kconfig.kgdb:27 Prompt: KGDB: use kprobe blocklist to prohibit unsafe breakpoints Depends on: KGDB [=y] && HAVE_KPROBES [=y] && MODULES [=y] Location: -> Kernel hacking -> Generic Kernel Debugging Instruments -> KGDB: kernel debugger (KGDB [=y]) Selects: KPROBES [=y]
