I am building a real time Ubuntu kernel for 20.04 LTS. The kernel version is intel-iotg-5.15.0-1036.41. I tried to build RT kernel by patching it with RT patch, v5.15.125-rt66 and v5.15.70-rt50. But the compile had errors and ... after building the kernel, when the PC turns on, PC said OUT of MEMORY. Is there the right kernel version for intel-iotg-5.15.0-1036.41 or 5.15.0-1016.21?
I built kernel as follows.
First I downloaded a 5.15.origin, and 5.15.0-1036.diff.
After unzip 5.15.origin, I patched using patch -p1 < 5.15.0-1036.diff.
And then, I patched kernel using patch -p1 < rt.patch.
cp /boot/config .config. Then, make menuconfig.
I set the config_preempt_rt and CONFIG_NO_HZ_FULL, CONFIG_HZ_1000 CPU_FREQ_DEFAULT_GOV_PERFORMANCE.
make -j 16 deb-pkg. But it was not working.
