Hello All I want to apply similar kernel version rt-patch in my rpi-basic-image for my raspberrypi4-64 machine. So, I tried to apply rt-patch for a standard rasbian image (5.15.61-v8+) but not got success. i did the following things.
1. I downloaded required kernel sources from the kernel building instructions ( Raspberry Pi Documentation - The Linux kernel) ( https://www.raspberrypi.com/documentation/computers/linux_kernel.html#building ) 2. I downloaded https://cdn.kernel.org/pub/linux/kernel/projects/rt/5.15/older/patch-5.15.65-rt49.patch.gz ( https://cdn.kernel.org/pub/linux/kernel/projects/rt/5.15/older/patch-5.15.65-rt49.patch.xz ) cd linux 3. zcat patch-5.15.65-rt49.patch.gz | patch -p1 But after rebooting my pi i am not able to see the patched kernel. I was about to do the same process with my rpi-basic-image. Can anyone tell me what things I am doing wrong? Or please tell me the standard way of rt-patching the kernel through yocto . Any reply would be highly appreicated. Thanks in Advance.
