If you are new to kernel compiling maybe you don't know that you can
optimize the kernel for your specific CPU architecture, if you are using
the GCC compiler:
first make a backup copy of the Makefile:
$ cd linux-source-6.1
$ cp arch/x86/Makefile arch/x86/Makefile.backup
then edit "arch/x86/Makefile":
$ cd linux-source-6.1
$ vi arch/x86/Makefile
at line 152 change:
cflags-$(CONFIG_MK8) += -march=k8
to
cflags-$(CONFIG_MK8) += -march=znver3
and below at line 159 change
rustflags-$(CONFIG_MK8) += -Ctarget-cpu=k8
to
rustflags-$(CONFIG_MK8) += -Ctarget-cpu=znver3
save and exit vim. "znver3" is the GCC's switch for the µarch of your
GPU.
