7 LoongArch is a new RISC ISA, which is a bit like MIPS or RISC-V. There are
10 (PLVs) defined in LoongArch: PLV0~PLV3, from high to low. Kernel runs at PLV0
12 instruction set, virtual memory and some other topics of LoongArch.
17 LoongArch registers include general purpose registers (GPRs), floating point
24 LoongArch has 32 GPRs ( ``$r0`` ~ ``$r31`` ); each one is 32-bit wide in LA32
29 The kernel uses a variant of the LoongArch register convention, as described in
30 the LoongArch ELF psABI spec, in :ref:`References <loongarch-references>`:
58 LoongArch has 32 FPRs ( ``$f0`` ~ ``$f31`` ) when FPU is present. Each one is
