There was a problem hiding this comment.
We should rename this file to xiangshan_defconfig and add nutshell_defconfig
Rename nemu_defconfig to xiangshan_defconfig. DEFAULT_DTB=nutshell or nutshell-* selects nutshell_defconfig (RV64IMAC/lp64); other names keep xiangshan_defconfig. A stamp records which defconfig last configured the Buildroot tree so switching rebuilds the SDK. Bootlin only ships lp64d, so the NutShell config builds gcc inside Buildroot and a linux.config fragment turns off FPU, V, and KVM. SPEC2006 follows the same DEFAULT_DTB switch and defaults to riscv_gcc16_rv64imac_lp64.cfg.

DEFAULT_DTB=nutshell or nutshell-* now selects nutshell_defconfig (RV64IMAC/lp64) in the same build/buildroot tree as XiangShan's nemu_defconfig. A stamp records which defconfig last configured that tree so switching rebuilds the SDK. Bootlin only ships lp64d, so the NutShell config builds gcc inside Buildroot and a linux.config fragment turns off FPU, V, and KVM.
SPEC2006 follows the same DEFAULT_DTB switch and defaults to riscv_gcc16_rv64imac_lp64.cfg.
