Looking at '龙芯 3A1000 处理器用户手册 下册 GS464 处理器核 V1.4' Chapter 3.22 'Config 3 寄存器(16,3)', Table 3-24, it seems the MSA bit is not set (which would make sense to me since the GS464 has the Loong-SIMD opcodes). Can you confirm CP0C3_MSAP bit should not be set in the 3A4000 (actually, any GS464-based)?

Loongson 3A4000 is actually a GS464V-based processor with MIPS MSA ASE. Unfortunately no document from Loongson was released to describe it's CP0 register values but I can confirm MIPS MSA is present on real hardware~ Actually there are few more ASE extensions in GS464V. But as they're not presented in public documents and toolchain, we're not going to implement it in QEMU. (Probably we should implement CPUCFG instruction in QEMU, which is used to probe features on Loongson-3A4000 just like cpuid for x86) Thanks. - Jiaxun > > Thanks, > > Phil. > >> + .mmu_type = MMU_TYPE_R4000, >> + }, >> + { >> /* A generic CPU providing MIPS64 DSP R2 ASE features. >> FIXME: Eventually this should be replaced by a real CPU model. */ >> .name = "mips64dspr2", >> diff --git a/target/mips/Makefile.objs b/target/mips/Makefile.objs >> index 91eb691..b820b3b 100644 >> --- a/target/mips/Makefile.objs >> +++ b/target/mips/Makefile.objs >> @@ -1,6 +1,6 @@ >> obj-y += translate.o cpu.o gdbstub.o helper.o >> obj-y += op_helper.o cp0_helper.o fpu_helper.o >> -obj-y += dsp_helper.o lmi_helper.o msa_helper.o >> +obj-y += dsp_helper.o lmmi_helper.o msa_helper.o >> obj-$(CONFIG_SOFTMMU) += mips-semi.o >> obj-$(CONFIG_SOFTMMU) += machine.o cp0_timer.o >> obj-$(CONFIG_KVM) += kvm.o >>
