Build Linux Real-Time patches problem!

[Evil_mage]

when I was build the linux souce(R36.4.4) code according ：

Kernel Customization — NVIDIA Jetson Linux Developer Guide

but a problem accuracy

./generic_rt_build.sh enable

I run this script ,and build the kernel, flash it .at las ,the kernel is not PREEMPT_RT。so I check the generic_rt_build.sh， and find the BSP(Linux) doesn’t exist rt-patched，so how can I apply/acquire the rt patches?

	if [ -d "${SCRIPT_DIR}"/kernel/"${KERNEL_SRC_DIR}"/rt-patches ]; then
		file_list=$(find "${SCRIPT_DIR}"/kernel/"${KERNEL_SRC_DIR}"/rt-patches -name \*.patch -type f | sort)
		for p in $file_list; do
			# set flag in case of failure and continue
			patch -s -d .. -p1 < "$p" || any_failure=1
			if [[ ${any_failure} -eq 1 ]] ; then
				echo "failed patching $p"
				return;
			fi
		done
		echo "The PREEMPT RT patches have been successfully applied!"
	fi

Hi,
On Jetpack 6 r36, the patches are all merged, so no need to apply any patch.

There is a patch for a later-discovered issue. If you would like to enable RT-kernel, please follow the steps in developer guide and also apply this patch:

Thanks a lot, I find the source code has applied rt patcheds:

and I make a mistake which forget copy the Image to kernel/Image。so flashing is still PREEMPT.
