usbmon support

Hi,

We went to mount the usbmon for the USB data monitor, but the module didn’t build-in, and we also couldn’t find the CONFIG_USB_MON parameter in tegra21_deconfig.
It seems that the kernel support usbmon from version 2.6xx, and we could find it in UBUNTU desktop version.
When I search the usbmon information as below, I could find the it.

ls /sys/kernel/debug/usb/usbmon

Is there any way we could build the usbmon in L4T-24.2.1?

Thanks

Hi,
r24.2.1 is on k3.10 and it looks like the function is not supported in arm64 architecture. Only see it present in arm:

(skip...)
./arch/arm/configs/tct_hammer_defconfig:CONFIG_USB_MON=y
./arch/arm/configs/nuc960_defconfig:CONFIG_USB_MON=y
./arch/arm/configs/at91sam9263_defconfig:CONFIG_USB_MON=y
./arch/arm/configs/at91sam9g20_defconfig:CONFIG_USB_MON=y
./arch/arm/configs/badge4_defconfig:CONFIG_USB_MON=y
./arch/arm/configs/em_x270_defconfig:CONFIG_USB_MON=y
(...ignore)

You may consider to upgrade to r28.2 which is k4.4.
