Hi,
I have a great piece of software, that apparently need HAVE_KPROBES_ON_FTRACE
To config the kernel option I’m using :
make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- menuconfig
The Kernel is Linux/arm64 6.6.63
When I’m doing a search inside menuconfig
i get:
Symbol: HAVE_KPROBES_ON_FTRACE [=n]
Type : bool
Defined at arch/Kconfig:223
Symbol: KPROBES_ON_FTRACE [=n]
Type : bool
Defined at arch/Kconfig:117
Depends on: KPROBES [=y] && HAVE_KPROBES_ON_FTRACE [=n] && DYNAMIC_FTRACE_WITH_REGS [=n]
But I found it no where in the menu…
and if I add it mannuly in the .config
file, then make some more other adapations in menuconfig
my manual entry disappear…
Any ideas ?
Maybe HAVE_KPROBES_ON_FTRACE
is not supported in 6.6.63 ?
Thanks
Thanks @SteveTech@programming.dev
I suppose the file
linux/arch/Kconfig
is the base the menuconfig to know which option is available ? right ?Thanks.
Yes, but it doesn’t look like
KPROBES_ON_FTRACE
is supported on arm64. I did find this patch though which implements it: https://patchwork.kernel.org/project/linux-arm-kernel/patch/20191218140622.57bbaca5@xhacker.debian/If you don’t know how to apply a patch, you can either paste the link into
